GENERAL POWER TOOL SAFETY WARNINGS



WARNING: Read all safety warnings, instructions, illustrations and specifications

provided with this power tool. Failure to follow all instructions listed below may result in

electric shock, fire and/or seriousinjury.

SAVE ALL WARNINGS AND INSTRUCTIONS FOR FUTURE

REFERENCE

The term “power tool” in the warnings refers to your mains-operated (corded) power tool or battery-

operated (cordless) powertool.

1) Work Area Safety

a ) Keep work area clean and well lit. Cluttered or dark areas inviteaccidents.

b ) Do not operate power tools in explosive atmospheres, such as in the presence of

flammable liquids, gases or dust. Power tools create sparks which may ignite the dust

orfumes.

c ) Keep children and bystanders away while operating a power tool. Distractions can

cause you to losecontrol.

2) Electrical Safety

a ) Power tool plugs must match the outlet. Never modify the plug in any way. Do not

use any adapter plugs with earthed (grounded) power tools. Unmodified plugs and

matching outlets will reduce risk of electricshock.

b ) Avoid body contact with earthed or grounded surfaces such as pipes, radiators,

ranges and refrigerators. There is an increased risk of electric shock if your body is earthed

orgrounded.

c ) Do not expose power tools to rain or wet conditions. Water entering a power tool will

increase the risk of electricshock.

d ) Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the

power tool. Keep cord away from heat, oil, sharp edges or moving parts. Damaged

or entangled cords increase the risk of electricshock.

e ) When operating a power tool outdoors, use an extension cord suitable for outdoor

use. Use of a cord suitable for outdoor use reduces the risk of electricshock.

f ) If operating a power tool in a damp location is unavoidable, use a ground

fault circuit interrupter (GFCI) protected supply. Use of a GFCI reduces the risk of

electricshock.

3) Personal Safety

a ) Stay alert, watch what you are doing and use common sense when operating a

power tool. Do not use a power tool while you are tired or under the influence of

drugs, alcohol or medication. A moment of inattention while operating power tools may

result in serious personalinjury.

b ) Use personal protective equipment. Always wear eye protection. Protective

equipment such as dust mask, non-skid safety shoes, hard hat, or hearing protection used for

appropriate conditions will reduce personalinjuries.

c ) Prevent unintentional starting. Ensure the switch is in the off position before

connecting to power source and/or battery pack, picking up or carrying the tool.

Carrying power tools with your finger on the switch or energizing power tools that have the

switch on invitesaccidents.

d ) Remove any adjusting key or wrench before turning the power tool on. A wrench or a

key left attached to a rotating part of the power tool may result in personalinjury.

e ) Do not overreach. Keep proper footing and balance at all times. This enables better

control of the power tool in unexpectedsituations.

f ) Dress properly. Do not wear loose clothing or jewelry. Keep your hair, clothing and

gloves away from moving parts. Loose clothes, jewelry or long hair can be caught in

movingparts.

g ) If devices are provided for the connection of dust extraction and collection facilities,

ensure these are connected and properly used. Use of dust collection can reduce dust-

relatedhazards.

h ) Do not let familiarity gained from frequent use of tools allow you to become

complacent and ignore tool safety principles. A careless action can cause severe injury

within a fraction of asecond.

4) Power Tool Use and Care

a ) Do not force the power tool. Use the correct power tool for your application. The

correct power tool will do the job better and safer at the rate for which it wasdesigned.

b ) Do not use the power tool if the switch does not turn it on and off. Any power tool that

cannot be controlled with the switch is dangerous and must berepaired.

c ) Disconnect the plug from the power source and/or the battery pack from the power

tool before making any adjustments, changing accessories, or storing power tools.

Such preventive safety measures reduce the risk of starting the power toolaccidentally.

d ) Store idle power tools out of the reach of children and do not allow persons

unfamiliar with the power tool or these instructions to operate the power tool.

Power tools are dangerous in the hands of untrainedusers.

e ) Maintain power tools. Check for misalignment or binding of moving parts,

breakage of parts and any other condition that may affect the power tool’s

operation. If damaged, have the power tool repaired before use. Many accidents are

caused by poorly maintained powertools.

f ) Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting

edges are less likely to bind and are easier tocontrol.

g ) Use the power tool, accessories and tool bits, etc. in accordance with these

instructions, taking into account the working conditions and the work to be

performed. Use of the power tool for operations different from those intended could result

in a hazardoussituations.

h ) Keep handles and grasping surfaces dry, clean and free from oil and grease. Slippery

handles and grasping surfaces do not allow for safe handling and control of the tool in

unexpectedsituations.

5) Service

a ) Have your power tool serviced by a qualified repair person using only identical

replacement parts. This will ensure that the safety of the power tool ismaintained.

Safety Instructions for Miter Saws

a ) Miter saws are intended to cut wood or wood-like products, they cannot be used

with abrasive cut-off wheels for cutting ferrous material such as bars, rods, studs,

etc. Abrasive dust causes moving parts such as the lower guard to jam. Sparks from abrasive

cutting will burn the lower guard, the kerf insert and other plasticparts.

b ) Use clamps to support the workpiece whenever possible. If supporting the

workpiece by hand, you must always keep your hand at least 4" (100 mm) from

either side of the saw blade. Do not use this saw to cut pieces that are too small to

be securely clamped or held by hand. If your hand is placed too close to the saw blade,

there is an increased risk of injury from bladecontact.

c ) The workpiece must be stationary and clamped or held against both the fence and

the table. Do not feed the workpiece into the blade or cut “freehand” in any way.

Unrestrained or moving workpieces could be thrown at high speeds, causinginjury.

d ) Push the saw through the workpiece. Do not pull the saw through the workpiece. To

make a cut, raise the saw head and pull it out over the workpiece without cutting,

start the motor, press the saw head down and push the saw through the workpiece.

Cutting on the pull stroke is likely to cause the saw blade to climb on top of the workpiece

and violently throw the blade assembly towards theoperator.

e ) Never cross your hand over the intended line of cutting either in front or behind the

saw blade. Supporting the workpiece “cross handed” i.e. holding the workpiece to the right

of the saw blade with your left hand or vice versa is verydangerous.

f ) Do not reach behind the fence with either hand closer than 4" (100 mm) from

either side of the saw blade, to remove wood scraps, or for any other reason while

the blade is spinning. The proximity of the spinning saw blade to your hand may not be

obvious and you may be seriouslyinjured.

g ) Inspect your workpiece before cutting. If the workpiece is bowed or warped, clamp

it with the outside bowed face toward the fence. Always make certain that there

is no gap between the workpiece, fence and table along the line of the cut. Bent or

warped workpieces can twist or shift and may cause binding on the spinning saw

blade while cutting. There should be no nails or foreign objects in theworkpiece.

h ) Do not use the saw until the table is clear of all tools, wood scraps, etc., except

for the workpiece. Small debris or loose pieces of wood or other objects that contact the

revolving blade can be thrown with highspeed.

i ) Cut only one workpiece at a time. Stacked multiple workpieces cannot be adequately

clamped or braced and may bind on the blade or shift duringcutting.

j ) Ensure the miter saw is mounted or placed on a level, firm work surface before use.

A level and firm work surface reduces the risk of the miter saw becomingunstable.

k ) Plan your work. Every time you change the bevel or miter angle setting, make sure

the fence will not interfere with the blade or the guarding system. Without turning

the tool “ON” and with no workpiece on the table, move the saw blade through a complete

simulated cut to assure there will be no interference or danger of cutting thefence.

l ) Provide adequate support such as table extensions, saw horses, etc. for a workpiece

that is wider or longer than the table top. Workpieces longer or wider than the miter

saw table can tip if not securely supported. If the cut-off piece or workpiece tips, it can lift the

lower guard or be thrown by the spinningblade.

m ) Do not use another person as a substitute for a table extension or as additional

support. Unstable support for the workpiece can cause the blade to bind or the workpiece to

shift during the cutting operation pulling you and the helper into the spinningblade.

n ) The cut-off piece must not be jammed or pressed by any means against the

spinning saw blade. If confined, i.e. using length stops, the cut-off piece could get wedged

against the blade and thrownviolently.

o ) Always use a clamp or a fixture designed to properly support round material such

as rods or tubing. Rods have a tendency to roll while being cut, causing the blade to “bite”

and pull the work with your hand into theblade.

p ) Let the blade reach full speed before contacting the workpiece. This will reduce the risk

of the workpiece beingthrown.

q ) If the workpiece or blade becomes jammed, turn the miter saw off. Wait for all

moving parts to stop and disconnect the plug from the power source and/or remove

the battery pack. Then work to free the jammed material. Continued sawing with a

jammed workpiece could cause loss of control or damage to the mitersaw.

ENGLISH

r ) After finishing the cut, release the switch, hold the saw head down and wait for

the blade to stop before removing the cut-off piece. Reaching with your hand near the

coasting blade isdangerous.

s ) Hold the handle firmly when making an incomplete cut or when releasing the

switch before the saw head is completely in the down position. The braking action of

the saw may cause the saw head to be suddenly pulled downward, causing a risk ofinjury.

Additional Safety Rules for Miter Saws



WARNING: Do not allow familiarity (gained from frequent use of your saw) to replace

safety rules. Always remember that a careless fraction of a second is sufficient to inflict

severeinjury.



WARNING: Never modify the power tool or any part of it. Damage or personal injury

couldresult.

• DO NOT OPERATE THIS MACHINE until it is completely assembled and installed according to

the instructions. A machine incorrectly assembled can cause seriousinjury.

• OBTAIN ADVICE from your supervisor, instructor, or another qualified person if you are not

thoroughly familiar with the operation of this machine. Knowledge issafety.

• FOLLOW ALL WIRING CODES and recommended electrical connections to prevent shock

or electrocution. Protect electric supply line with at least a 15 ampere time-delay fuse or a

circuitbreaker.

• MAKE CERTAIN the blade rotates in the correct direction. The teeth on the blade should point in

the direction of rotation as marked on thesaw.

• TIGHTEN ALL CLAMP HANDLES, knobs and levers prior to operation. Loose clamps can cause

parts or the workpiece to be thrown at highspeeds.

• BE SURE all blade and blade clamps are clean, recessed sides of blade clamps are against blade

and arbor screw is tightened securely. Loose or improper blade clamping may result in damage

to the saw and possible personalinjury.

• DO NOT OPERATE ON ANYTHING OTHER THAN THE DESIGNATED VOLTAGE for the saw.

Overheating, damage to the tool and personal injury mayoccur.

• DO NOT WEDGE ANYTHING AGAINST THE FAN to hold the motor shaft. Damage to tool and

possible personal injury mayoccur.

• NEVER CUT FERROUS METALS or masonry. Either of these can cause the carbide tips to fly off

the blade at high speeds causing seriousinjury.

• NEVER PLACE HANDS CLOSER THAN 4" (100 mm) FROM THEBLADE.

• NEVER HAVE ANY PART OF YOUR BODY IN LINE WITH THE PATH OF THE SAW BLADE.

Personal injury willoccur.

• NEVER APPLY BLADE LUBRICANT TO A RUNNING BLADE. Applying lubricant could cause

your hand to move into the blade resulting in seriousinjury.

• DO NOT place either hand in the blade area when the saw is connected to the power source.

Inadvertent blade activation may result in seriousinjury.

• NEVER REACH AROUND OR BEHIND THE SAW BLADE. A blade can cause seriousinjury.

• DO NOT REACH UNDERNEATH THE SAW unless it is unplugged and turned off. Contact with

saw blade may cause personalinjury.

• SECURE THE MACHINE TO A STABLE SUPPORTING SURFACE. Vibration can possibly cause

the machine to slide, walk, or tip over, causing seriousinjury.

• USE ONLY CROSSCUT SAW BLADES recommended for miter saws. For best results, do not

use carbide tipped blades with hook angles in excess of 7 degrees. Do not use blades with deep

gullets. These can deflect and contact the guard, and can cause damage to the machine and/or

seriousinjury.

• USE ONLY BLADES OF THE CORRECT SIZE AND TYPE specified for this tool to prevent

damage to the machine and/or seriousinjury.

• INSPECT BLADE FOR CRACKS or other damage prior to operation. A cracked or damaged

blade can come apart and pieces can be thrown at high speeds, causing serious injury. Replace

cracked or damaged bladesimmediately.

• CLEAN THE BLADE AND BLADE CLAMPS prior to operation. Cleaning the blade and blade

clamps allows you to check for any damage to the blade or blade clamps. A cracked or damaged

blade or blade clamp can come apart and pieces can be thrown at high speeds, causing

seriousinjury.

• DO NOT USE WARPED BLADES. Check to see if the blade runs true and is free from vibration. A

vibrating blade can cause damage to the machine and/or seriousinjury.

• DO NOT use lubricants or cleaners (particularly spray or aerosol) in the vicinity of the plastic

guard. The polycarbonate material used in the guard is subject to attack by certainchemicals.

• KEEP GUARD IN PLACE and in workingorder.

• ALWAYS USE THE KERF PLATE AND REPLACE THIS PLATE WHEN DAMAGED. Small chip

accumulation under the saw may interfere with the saw blade or may cause instability of

workpiece whencutting.

• USE ONLY BLADE CLAMPS SPECIFIED FOR THIS TOOL to prevent damage to the machine

and/or seriousinjury.

• CLEAN THE MOTOR AIR SLOTS of chips and sawdust. Clogged motor air slots can cause the

machine to overheat, damaging the machine and possibly causing a short which could cause

seriousinjury.

• NEVER LOCK THE SWITCH IN THE “ON” POSITION. Severe personal injury mayresult.

• NEVER STAND ON TOOL. Serious injury could occur if the tool is tipped or if the cutting tool is

unintentionallycontacted.

• ADDITIONAL INFORMATION regarding the safe and proper operation of power tools (i.e., a

safety video) is available from the Power Tool Institute, 1300 Sumner Avenue, Cleveland, OH

44115-2851 (www.powertoolinstitute.com). Information is also available from the National

Safety Council, 1121 Spring Lake Drive, Itasca, IL 60143-3201. Please refer to the American

National Standards Institute ANSI 01.1 Safety Requirements for Woodworking Machines and the

U.S. Department of Labor OSHA 1910.213Regulations.



WARNING: Cutting plastics, sap coated wood, and other materials may cause melted

material to accumulate on the blade tips and the body of the saw blade, increasing the risk

of blade overheating and binding whilecutting.



WARNING: ALWAYS use safety glasses. Everyday eyeglasses are NOT safety glasses.

Also use face or dust mask if cutting operation is dusty. ALWAYS WEAR CERTIFIED

SAFETYEQUIPMENT:

• ANSI Z87.1 eye protection (CAN/CSA Z94.3),

• ANSI S12.6 (S3.19) hearing protection,

• NIOSH/OSHA/MSHA respiratoryprotection.



WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other

construction activities contains chemicals known to the State of California to cause cancer,

birth defects or other reproductive harm. Some examples of these chemicalsare:

• lead from lead-based paints,

• crystalline silica from bricks and cement and other masonry products, and

• arsenic and chromium from chemically-treatedlumber.

Your risk from these exposures varies, depending on how often you do this type of work. To reduce

your exposure to these chemicals: work in a well ventilated area, and work with approved safety

equipment, such as those dust masks that are specially designed to filter out microscopicparticles.

• Avoid prolonged contact with dust from power sanding, sawing, grinding, drilling, and

other construction activities. Wear protective clothing and wash exposed areas with

soap and water. Allowing dust to get into your mouth, eyes, or lay on the skin may promote

absorption of harmfulchemicals.



WARNING: Use of this tool can generate and/or disperse dust, which may cause serious

and permanent respiratory or other injury. Always use NIOSH/OSHA approved respiratory

protection appropriate for the dust exposure. Direct particles away from face andbody.



WARNING: Always wear proper personal hearing protection that conforms to ANSI

S12.6 (S3.19) during use. Under some conditions and duration of use, noise from this

product may contribute to hearingloss.

• Air vents often cover moving parts and should be avoided. Loose clothes, jewelry or long

hair can be caught in movingparts.

• An extension cord must have adequate wire size (AWG or American Wire Gauge) for

safety. The smaller the gauge number of the wire, the greater the capacity of the cable, that is,

16 gauge has more capacity than 18 gauge. An undersized cord will cause a drop in line voltage

resulting in loss of power and overheating. When using more than one extension to make up

the total length, be sure each individual extension contains at least the minimum wire size. The

following table shows the correct size to use depending on cord length and nameplate ampere

rating. If in doubt, use the next heavier gauge. The lower the gauge number, the heavier thecord.

Double Insulation

Double insulated tools are constructed throughout with two separate layers of electrical

insulation or one single layer of reinforced insulation between you and the tool’s electrical

system. Tools built with this insulation system are not intended to be grounded. As a result,

your tool is equipped with a two prong plug which permits you to use extension cords without

concern for maintaining a groundconnection.

NOTE: Double insulation does not take the place of normal safety precautions when operating

this tool. The secondary insulation system is for protection against injury resulting from a possible

failure of the primary insulation within thetool.



CAUTION: WHEN SERVICING USE ONLY IDENTICAL REPLACEMENT PARTS. Repair or replace

damagedcords.

Polarized Plugs

Polarized plugs (one blade is wider than the other) are used on equipment to reduce the risk of

electric shock. When provided, this plug will fit in the polarized outlet only one way. If the plug

does not fit fully in the outlet, reverse the plug. If it still does not fit, contact a qualified electrician

to install the proper outlet. Do not change the plug in any way.

Electrical Connection

Be sure your power supply agrees with the nameplate marking. 120 volts, AC means that your

saw will operate on alternating current only. A voltage decrease of 10 percent or more will cause

a loss of power and overheating. All

DeWALT

tools are factory tested. If this tool does not operate,

check the powersupply.

Intended Use

This heavy duty miter saw is designed for professional wood cuttingapplications.

DO NOT use under wet conditions or in presence of flammable liquids orgases.

This miter saw is a professional power tool. DO NOT let children come into contact with the tool.

Supervision is required when inexperienced operators use thistool.

Familiarization (Fig. A, B)

Your miter saw is not fully assembled in the carton.Refer to the Assembly section for assembly

instructions. Open the box and lift the saw out by the convenient carrying handle

13

, as shown

in FigureB.

Place the saw on a smooth, flat surface such as a workbench or strongtable.

Examine Figure A to become familiar with the saw and its various parts. The section on

adjustments will refer to these terms and you must know what and where the partsare.



CAUTION: Pinch Hazard. To reduce the risk of injury, keep thumb underneath the handle

when pulling the handle down. The lower guard will move up as the handle is pulled down

which could cause pinching.The handle is placed close to the guard for specialcuts.

Press down lightly on the operating handle

2

and pull lock down pin

17

. Gently release the

downward pressure and hold the arm allowing it to rise to its full height. Use the lock down pin

when carrying the saw from one place to another. Always use the lifting handle

13

to transport

the saw or the hand indentations

9

Bench Mounting (Fig. A)

Mounting holes

3

are provided in all 4 feet to facilitate bench mounting, as shown in FigureA.

(Two different-sized holes are provided to accommodate different sizes of screws. Use either

hole, it is not necessary to use both.) Always mount your saw firmly to a stable surface to prevent

movement. To enhance the tool’s portability, it can be mounted to a piece of 1/2” (12.7 mm) or

thicker plywood which can then be clamped to your work support or moved to other job sites

andreclamped.

NOTE: If you elect to mount your saw to a piece of plywood, make sure that the mounting

screws don’t protrude from the bottom of the wood. The plywood must sit flush on the work

support. When clamping the saw to any work surface, clamp only on the clamping bosses where

the mounting screw holes are located. Clamping at any other point will surely interfere with the

proper operation of thesaw.



CAUTION: To prevent binding and inaccuracy, be sure the mounting surface is not warped

or otherwise uneven. If the saw rocks on the surface place a thin piece of material under one

saw foot until the saw sits firmly on the mountingsurface.

Installing a Blade

1. Unplug thesaw.

2. With the arm raised, the lower guard held open and the guard bracket raised, place the blade

on the spindle, onto the blade adapter [if using a blade with a 1" (25.4 mm) diameter blade

hole] and against the inner blade clamp with the teeth at the bottom of the blade pointing

toward the back of thesaw.

3. Assemble the outer blade clamp onto thespindle.

4. Install the blade screw

34

and, engaging the spindle lock, tighten the screw firmly with the

blade wrench provided. (Turn counterclockwise, left-hand threads.)

NOTE: When using blades with a 5/8" (15.88 mm) diameter blade hole, the blade adapter will

not be used and should be stored in a safe place for futureuse.

5. Return the guard bracket to its original position and firmly tighten the guard bracket

screw

58

to hold bracket inplace.



WARNING:

• The guard bracket must be returned to its original position and the screw

tightened before activating thesaw.

• Failure to do so may allow the guard to contact the spinning saw blade resulting

in damage to the saw and severe personalinjury.

Miter Scale Adjustment (Fig. A, G)

Unlock the miter lock handle

5

and swing the miter arm until the miter latch button

6

locks

it at the 0° miter position. Do not lock the miter lock handle. Place a square against the saw’s

fence and blade, as shown. (Do not touch the tips of the blade teeth with the square. To do

so will cause an inaccurate measure ment.) If the saw blade is not exactly perpendicular to the

fence

10

, loosen the four miter scale screws

8

that hold the miter scale and move the miter

lock handle and the scale left or right until the blade is perpendicular to the fence, as measured

with the square. Retighten the four screws. Pay no attention to the reading of the miter pointer

at thistime.

ENGLISH

Fig. G

Miter Pointer Adjustment (Fig. A)

Unlock the miter lock handle

5

to move the miter arm to the zero position. With the miter lock

handle unlocked, allow the miter latch to snap into place as you rotate the miter arm to zero.

Observe the miter pointer

30

and miter scale

7

shown in FigureA. If the pointer does not

indicate exactly zero, loosen the miter pointer screw

26

holding the pointer in place, reposition

the pointer and tighten thescrew.

Bevel Square to Table (Fig. A, H, I)

To align the blade square to the table

16

, lock the arm in the down position with the lock down

pin

17

. Place a square against the blade, ensuring the square is not on top of a tooth. Loosen

the bevel lock knob

and ensure the arm is firmly against the 0° bevel stop. Rotate the 0° bevel

adjustment screw

41

with the 1/2” blade wrench as necessary so that the blade is at 0° bevel to

thetable.

Fig. H

Fig. I

Bevel Pointer (Fig. I)

If the bevel pointer

42

does not indicate zero, loosen the screw

43

that holds it in place and

move the pointer as necessary. Ensure the 0° bevel is correct and the bevel pointers are set before

adjusting any other bevel anglescrews.

Adjusting the Bevel Stop to 45° Left or Right (Fig. A, I)

To adjust the right 45° bevel angle, loosen the bevel lock knob

11

and pull the 0° bevel stop

to override the 0° bevel stop. When the saw is fully to the right, if the bevel pointer does not

indicate exactly 45°, turn the left 45° bevel adjustment screw

44

with the 1/2” blade wrench

until the bevel pointer indicates 45°.

To adjust the left 45° bevel stop, first loosen the bevel lock knob and tilt the head to the left. If the

bevel pointer does not indicate exactly 45°, turn the right 45° bevel adjustment screw

44

until

the bevel pointer

42

reads 45°.

Adjusting the Bevel Stop to 22.5° (or 33.9°) (Fig. A, I)

NOTE: Adjust the bevel angles only after performing the 0° bevel angle and bevel

pointeradjustment.

• To set the left 22.5° bevel angle, flip out the left 22.5° bevel pawl

46

. Loosen the bevel lock

knob

11

and tilt the head fully to the left. If the bevel pointer does not indicate exactly 22.5°,

turn the crown adjustment screw

45

contacting the pawl with a 7/16” wrench until the

bevel pointer reads 22.5°.

• To adjust the right 22.5° bevel angle, flip out the right 22.5° bevel pawl. Loosen the bevel lock

knob and pull the 0° bevel stop to override the 0° bevel stop. When the saw is fully to the

right, if the bevel pointer does not indicate exactly 22.5°, turn the crown adjustment screw

contacting the pawl with a 7/16” wrench until the bevel pointer indicates exactly22.5°.

Fence Adjustment (Fig. A)

In order that the saw can bevel to many bevel positions, one of the fences may have to be

adjusted to provide clearance. To adjust each fence, loosen the fence adjustment knob

14

and slide the fence outward. Make a dry run with the saw turned off and check for clearance.

Adjust the fence to be as close to the blade as practical to provide max imum workpiece support,

without interfering with arm up and down movement. Tighten the fence adjustment knob

securely. When the bevel operations are complete, don’t forget to relocate thefence.

For certain cuts, it may be desirable to bring the fences closer to the blade. To use this feature,

back the fence adjustment knobs out two turns and move the fences closer to the blade past the

normal limit, then tighten the fence adjustment knobs to keep the fences in this location. When

using this feature, make a dry cut first to ensure the blade does not contact thefences.

NOTE: The tracks of the fences can become clogged with sawdust. If you notice that they are

becoming clogged, use a brush or some low pressure air to clear the guidegrooves.

Guard Actuation and Visibility (Fig. A, Z)



CAUTION: Pinch Hazard. To reduce the risk of injury, keep thumb underneath the handle

when pulling the handle down. The lower guard will move up as the handle is pulled down

which could causepinching.

The lower guard

4

on your saw has been designed to automatically uncover the blade when the

arm is brought down and to cover the blade when the arm israised.

The guard can be raised by hand when installing or removing saw blades or for inspection of the

saw. NEVER RAISE THE LOWER GUARD MANUALLY UN LESS THE BLADE ISSTOPPED.

NOTE: Certain special cuts of large material will require that you manually raise the guard. Refer

to Cutting Large Material under SpecialCuts.

The front section of the guard is louvered for visibility while cutting. Although the louvers

dramatically reduce flying debris, they are openings in the guard and safety glasses should be

worn at all times when viewing through thelouvers.

Kerf Plate Adjustment (Fig. A)

To adjust the kerf plates

25

, loosen the screws holding the kerf plates in place. Adjust so that the

kerf plates are as close as possible without interfering with the blade’smovement.

If a zero kerf width is desired, adjust the kerf plates as close to each other as possible. They can

now be cut slowly with the saw blade to give the smallest gap possible between the blade and

the kerfplates.

Rail Guide Adjustment (Fig. A)

Periodically check the rails

23

for any play or clearance. The right rail can be adjusted with the

rail set screw 

31

shown in FigureA. To reduce clearance, use a 4 mm hex wrench and rotate the

rail set screw clockwise gradually while sliding the saw head back and forth. Reduce play while

maintaining minimum slideforce.

Miter Lock Adjustment (Fig. A, J)

The miter lock rod

47

should be adjusted if the table of the saw can be moved when the

miter lock handle

5

is locked (down). To adjust the miter lock, put the miter lock handle in the

unlocked (up) position. Using a 1/2” open end wrench, loosen the lock

48

nut on the miter lock

rod. Using a slotted screwdriver, tighten the miter lock rod by turning it clockwise. Turn the lock

rod until it is snug, then turn counterclockwise one turn. To ensure the miter lock is functioning

properly, re-lock the miter lock to a non-detented measurement on the miter scale – for example,

34º – and make sure the table will not rotate. Tighten locknut.

Controls

Your compound miter saw has several main controls, which will be discussed briefly here. For

more information on these controls, see the respective sections later in themanual.

Miter Control (Fig. A)

The miter lock handle

5

and miter latch button

6

allow you to miter your saw to 60° right and

50° left. To miter the saw, lift the miter lock handle, push the miter latch button and set the miter

angle desired on the miter scale

7

. Push down on the miter lock handle to lock the miterangle.

Trigger Switch (Fig. A)

The trigger switch

1

turns your saw on and off. A hole is provided in the trigger for insertion of a

padlock to secure thesaw.

Miter Latch Override (Fig. A)

The miter latch override

22

allows your saw to override the common stop angles. To override

the common stop angles, push the miter latch button

6

and flip the miter latch override lever to

the verticalposition.

Bevel Lock Knob (Fig. A)

The bevel lock knob

11

allows you to bevel the saw 49° left or right. To adjust the bevel setting,

turn the knob counterclockwise. The saw head bevels easily to the left or to the right once the 0°

bevel override knob is pulled. To tighten, turn the bevel lock knobclockwise.

0° Bevel Override (Fig. A)

The bevel stop override allows you to bevel the saw to the right past the 0°mark.

When engaged, the saw will automatically stop at 0° when brought up from the left. To

temporarily move past 0° to the right, pull the bevel lock knob

11

. Once the knob is released, the

override will be reengaged. The bevel lock knob can be locked out by twisting the knob 180°.

When at 0°, the override locks in place. To operate the override, bevel the saw slightly to theleft.

45° Bevel Stop Override (Fig. I)

There are two bevel stop override levers

49

, one on each side of the saw. To bevel the saw, left

or right, past 45°, push the 45° bevel override lever rearward. When in the rearward position,

the saw can bevel past these stops. When the 45° stops are needed, pull the 45° bevel override

leverforward.

Crown Bevel Pawls (Fig. I)

When cutting crown molding laying flat, your saw is equipped to accurately and rapidly set a

crown stop, left or right (refer to

Instructions for Cutting Crown Molding Laying Flat and

Using the Compound Features). The crown bevel pawl

50

can be rotated to contact the crown

adjustment screw

45

. The saw is factory set to be used for typical crown in North America

(52/38), but can be reversed to cut non-typical (45/45) crown. To reverse the crown bevel pawl,

remove the retaining screw, the 22.5° bevel pawl and the 33.9° crown bevel pawl. Flip the crown

bevel pawl so the 30° text is facing up. Reattach the screw to secure the 22.5° bevel pawl and the

crown bevel pawl. The accuracy setting will not beaffected.

22.5° Bevel Pawls (Fig. I)

Your saw is equipped to rapidly and accurately set a 22.5° bevel, left or right. The 22.5° bevel

pawl 

46

can be rotated to contact the crown adjustmentscrew.

Rail Lock Knob (Fig. A)

The rail lock knob

29

allows you to lock the saw head firmly to keep it from sliding on the rails.

This is necessary when making certain cuts or when transporting thesaw.

Depth Stop (Fig. A)

The depth stop

24

allows the depth of cut of the blade to be limited. The stop is useful for

applications such as grooving and tall vertical cuts. Rotate the depth stop forward and adjust the

depth adjustment screw

28

to set the desired depth of cut. To secure the adjustment, tighten

the wing nut

20

. Rotating the depth stop to the rear of the saw will bypass the depth stop

feature. If the depth adjustment screw is too tight to loosen by hand, the provided blade wrench

can be used to loosen thescrew.

Lock Down Pin (Fig. A)



WARNING: The lock down pin should be used only when carrying or storing the saw. NEVER

use the lock down pin for any cuttingoperation.

To lock the saw head in the down position, push the saw head down, push the lock down pin

17

in and release the saw head. This will hold the saw head safely down for moving the saw from

place to place. To release, press the saw head down and pull the pinout.

Slide Lock Lever (Fig. K)

The slide lock lever

places the saw in a position to maximize cutting of base molding when

cut vertically as shown in FigureK.

Fig. K

Automatic Electric Brake

Your saw is equipped with an automatic electric blade brake which stops the saw blade within 5

seconds of trigger release. This is notadjustable.

On occasion, there may be a delay after trigger release to brake engagement. On rare occasions,

the brake may not engage at all and the blade will coast to astop.

If a delay or “skipping” occurs, turn the saw on and off 4 or 5 times. If the condition persists, have

the tool serviced by an authorized D

WALT servicecenter.

Always be sure the blade has stopped before removing it from the kerf. The brake is not a

substitute for guards or for ensuring your own safety by giving the saw your completeattention.

OPERATION



WARNING: To reduce the risk of serious personal injury, turn unit off and disconnect

it from power source before making any adjustments or removing/installing

attachments or accessories. An accidental start-up can causeinjury.



WARNING: Always use eye protection. All users and bystanders must wear eye protection

that conforms to ANSI Z87.1 (CAN/CSA Z94.3).

Plug the saw into any household 60 Hz power source. Refer to the nameplate for voltage. Be sure

the cord will not interfere with yourwork.

Body and Hand Position (Fig. L1–L4)



WARNING: To reduce the risk of serious personal injury, ALWAYS use proper hand position

asshown.



WARNING: To reduce the risk of serious personal injury, ALWAYS hold securely in anticipation of

a suddenreaction.

Proper positioning of your body and hands when operating the miter saw will make cutting

easier, more accurate and safer. Never place hands near cutting area. Place hands no closer than

4" (100mm) from the blade. Hold the workpiece tightly to the table and the fence when cutting.

Keep hands in position until the trigger has been released and the blade has completely stopped.

ALWAYS MAKE DRY RUNS (UNPOWERED) BEFORE FINISH CUTS SO THAT YOU CAN CHECK THE

PATH OF THE BLADE. DO NOT CROSS ARMS, AS SHOWN IN FIGUREL3.

Keep both feet firmly on the floor and maintain proper balance. As you move the miter arm

left and right, follow it and stand slightly to the side of the saw blade. Sight through the guard

louvers when following a pencilline.

Fig. L1 Fig. L2

ENGLISH

Fig. L3 Fig. L4

Trigger Switch (Fig. M)

To turn the saw on, push the lock-off lever

39

to the left, then depress the trigger switch

1

. The

saw will run while the switch is depressed. Allow the blade to spin up to full operating speed

before making the cut. To turn the saw off, release the switch. Allow the blade to stop before

raising the saw head. There is no provision for locking the switch on. A hole

54

is provided in the

trigger for insertion of a padlock to lock the switchoff.

Always be sure the blade has stopped before removing it from thekerf.

Fig. M

Dust Extraction (Fig. N)

Your saw has a built-in dust port

15

that allows either the supplied dust bag or a shop vacuum

system to beconnected.

NOTE: This saw has a dust port equipped with an AirLock

fitting, which is a universal system

that connects tools to dust extraction shrouds to minimize cleanup on thejobsite.

To Attach the Dust Bag

1. Fit the dust bag

37

to the dust port

15

as shown in FigureN.

Fig. N

Use of XPS

LED Worklight System (Fig. A)

NOTE: The miter saw must be connected to a powersource.

The XPS

LED Worklight System is equipped with an ON/OFF switch

19

. The XPS

LED

Worklight System is independent of the miter saw’s triggerswitch.

The light does not need to be on in order to operate thesaw.

To cut through an existing pencil line on a piece of wood, turn on the XPS

system, then pull

down on the operating handle to bring the saw blade close to the wood. The shadow of the

blade will appear on the wood. This shadow line represents the material that the blade will

remove when performing a cut. To correctly locate your cut to the pencil line, align the pencil

line with the edge of the blade’s shadow. Keep in mind that you may have to adjust the miter or

bevel angles in order to match the pencil lineexactly.

Through-Cutting Operations (Fig. A)

If the slide feature is not used, ensure the saw head is pushed back as far as possible and the

rail lock knob is tightened. This will prevent the saw from sliding along its rails as the workpiece

isengaged.

NOTE: Although this saw will cut wood and many non-ferrous materials, we will limit our

detailed discussion to the cutting of wood only. The same guidelines apply to the other

materials. DO NOT CUT FERROUS (IRON AND STEEL) MAT ERIALS OR MASONRY WITH THIS SAW.

Do not use any abrasiveblades.

NOTE: Refer to Guard Actuation and Visibility in the Adjustments section for important

information about the lower guard beforecutting.

Crosscuts (Fig. A, O)

A crosscut is made by cutting wood across the grain at any angle. A straight crosscut is made

with the miter arm at the zero degree position. Set and lock the miter arm at zero, hold the wood

firmly on the table and against the fence. With the rail lock knob tightened, turn on the saw by

squeezing the trigger switch

1

shown in FigureA.

When the saw comes up to speed (about 1 second) lower the arm smoothly and slowly to cut

through the wood. Let the blade come to a full stop before raising arm.

When cutting anything larger than a 2 x 8 (51 x 203mm [2 x 6 (51 x 152) at 45º miter]) use an

out-down-back motion with the rail lock knob loosened. Pull the saw out, toward you, lower the

saw head down toward the workpiece, and slowly push the saw back to complete the cut. Do

not allow the saw to contact the top of the workpiece while pulling out. The saw may run toward

you, possibly causing personal injury or damage to theworkpiece.

Cutting of multiple pieces is not recommended but can be done safely by ensuring that each

piece is held firmly against the table and fence.

NOTE: To provide greater crosscut capacity with reduced stroke, the blade on the DWS780

extends deeper into the table. As a result, a greater lifting force on the workpiece may be

experienced during thecut.



CAUTION: Always use a work clamp to maintain control and reduce the risk of workpiece

damage and personal injury, if your hands are required to be within 6” (152 mm) of the blade

during thecut.

NOTE: The rail lock knob

29

shown in Figure A must be loose to allow the saw to slide along its

rails

23

Miter crosscuts are made with the miter arm at some angle other than zero. This angle is often

45º for making corners, but can be set anywhere from zero to 50º left or 60° right. Make the cut as

described above.

When performing a miter cut on workpieces wider than a 2 x 6 that are shorter in length, always

place the longer side against the fence

10

(Figure O).

To cut through an existing pencil line on a piece of wood, match the angle as close as possible.

Cut the wood a little too long and measure from the pencil line to the cut edge to determine

which direction to adjust the miter angle and recut. This will take some practice, but it is a

commonly usedtechnique.

Fig. O

Bevel Cuts

A bevel cut is a crosscut made with the saw blade leaning at an angle to the wood. In order

to set the bevel, loosen the bevel lock

11

, and move the saw to the left or right as desired.

(It is necessary to move the fence to allow clearance.) Once the desired bevel angle has been

set, tighten the bevel lock firmly. Refer to the Controls section for detailed instructions on the

bevelsystem.

Bevel angles can be set from 49º right to 49º left and can be cut with the miter arm set between

50º left or 60º right. At some extreme angles, the right or left side fence might have to be

removed. To remove the left or right fence, unscrew the fence adjustment knob

14

several turns

and slide the fenceout.

NOTE: Refer to Fence Adjustment in the Adjustments section for important information on

adjusting the fences for certain bevelcuts.

Quality of Cut

The smoothness of any cut depends on a number of variables. Things like material being cut,

blade type, blade sharpness and rate of cut all contribute to the quality of thecut.

ENGLISH

When smoothest cuts are desired for molding and other precision work, a sharp (60 tooth

carbide) blade and a slower, even cutting rate will produce the desiredresults.

Ensure that the material does not move or creep while cutting; clamp it securely in place. Always

let the blade come to a full stop before raisingarm.

If small fibers of wood still split out at the rear of the workpiece, stick a piece of masking tape

on the wood where the cut will be made. Saw through the tape and carefully remove tape

whenfinished.

For varied cutting applications, refer to the list of recommended saw blades for your saw and

select the one that best fits your needs. Refer to Saw Blades underAccessories.

Non-Through-Cutting (Grooving and Rabbeting)

Instructions in the Crosscuts, Bevel Cuts and Cutting Compound Miters sections are for cuts

made through the full thickness of the material. The saw can also perform non-through cuts to

form grooves or rabbets in thematerial.

Groove Cut (Fig. A)

Refer to Depth Stop for detailed instructions for setting depth of cut. A piece of scrap wood

should be used to verify the desired depth of cut.

Hold the wood firmly on the table and against the fence

. Align the cut area underneath

the blade. Position the saw arm fully forward, with blade in down position. Turn on the saw by

squeezing the trigger switch

1

shown in FigureA. Smoothly, push saw arm rearward to cut a

groove through the workpiece.

Release the trigger switch with the saw arm down. When saw blade has completely stopped,

raise the saw arm. Always let the blade come to a full stop before raising thearm.

To widen the groove, repeat steps 1–4 until the desired width is obtained.

Clamping the Workpiece (Fig. A)



WARNING: To reduce the risk of serious personal injury, turn off the tool and

disconnect it from the power source before attempting to move it, change

accessories or make anyadjustments.



WARNING: A workpiece that is clamped, balanced and secure before a cut may become

unbalanced after a cut is completed. An unbalanced load may tip the saw or anything the

saw is attached to, such as a table or workbench. When making a cut that may become

unbalanced, properly support the workpiece and ensure the saw is firmly bolted to a stable

surface. Personal injury mayoccur.



WARNING: The clamp foot must remain clamped above the base of the saw whenever the

clamp is used. Always clamp the workpiece to the base of the saw–not to any other part of

the work area. Ensure the clamp foot is not clamped on the edge of the base of thesaw.



CAUTION: Always use a work clamp to maintain control and reduce the risk of workpiece

damage and personalinjury.

If you cannot secure the workpiece on the table and against the fence by hand, (irregular shape,

etc.) or your hand would be less than 4" (100mm) from the blade, a clamp or other fixture must

beused.

For best results use the vertical material clamp

21

provided with your saw. Additional DW7082

clamps can be purchased at your local retailer or

DeWALT

servicecenter.

Other aids such as spring clamps, bar clamps or C-clamps may be appropriate for certain sizes

and shapes of material. Use care in selecting and placing these clamps. Take time to make a dry

run before making the cut. The left fence will slide from side to side to aid in clamping

To Install Clamp (Fig. A)

1. Insert it into the hole behind the fence

10

. The clamp should be facing toward the back of

the miter saw. The groove on the clamp rod should be fully inserted into the base. Ensure this

groove is fully inserted into the base of the miter saw. If the groove is visible, the clamp will

not besecure.

2. Rotate the clamp 180º toward the front of the mitersaw.

3. Loosen the knob to adjust the clamp up or down, then use the fine adjust knob to firmly

clamp theworkpiece.

NOTE: Place the clamp on the opposite side of the base when beveling. ALWAYS MAKE DRY

RUNS (UNPOWERED) BEFORE FINISH CUTS TO CHECK THE PATH OF THE BLADE. ENSURE THE

CLAMP DOES NOT INTERFERE WITH THE ACTION OF THE SAW ORGUARDS.

Support for Long Pieces



WARNING: To reduce the risk of serious personal injury, turn off the tool and

disconnect it from the power source before attempting to move it, change

accessories or make anyadjustments.

ALWAYS SUPPORT LONGPIECES.

Never use another person as a substitute for a table extension; as additional support for a

workpiece that is longer or wider than the basic miter saw table or to help feed, support or pull

theworkpiece.

For best results, use the DW7080 extension work support to extend the table width of your saw,

available from your dealer at extracost.

Support long workpieces using any convenient means such as sawhorses or similar devices to

keep the ends fromdropping.

Cutting Picture Frames, Shadow Boxes And Other Four-Sided

Projects (Fig. P, Q)

To best understand how to make the items listed here, we suggest that you try a few simple

projects using scrap wood until you develop a “feel” for yoursaw.

Your saw is the perfect tool for mitering corners like the one shown in FigureP. Sketch 1 in

FigureQ shows a joint made by using the bevel adjustment to bevel the edges of the two boards

at 45º each to produce a 90º corner. For this joint the miter arm was locked in the zero position

and the bevel adjustment was locked at 45º. The wood was positioned with the broad flat side

against the table and the narrow edge against the fence. The cut could also be made by mitering

right and left with the broad surface against thefence.

Fig. P

Fig. Q

Cutting Trim Molding And Other Frames (Fig. Q)

Sketch 2 in FigureQ shows a joint made by setting the miter arm at 45º to miter the two boards

to form a 90º corner. To make this type of joint, set the bevel adjustment to zero and the miter

arm to 45º. Once again, position the wood with the broad flat side on the table and the narrow

edge against thefence.

The two sketches in FigureQ are for four-sided objectsonly.

As the number of sides changes, so do the miter and bevel angles. The chart below gives the

proper angles for a variety ofshapes.

– EXAMPLES –

NUMBER OF SIDES MITER OR BEVEL ANGLE

4 45°

5 36°

6 30°

7 25.7°

8 22.5°

9 20°

10 18°

The chart assumes that all sides are of equal length. For a shape that is not shown in the chart,

use the following formula: 180º divided by the number of sides equals the miter (if the material is

cut vertically) or bevel angle (if the material is cut laying flat).

Cutting Compound Miters (Fig. R)

A compound miter is a cut made using a miter angle and a bevel angle at the same time. This is

the type of cut used to make frames or boxes with slanting sides like the one shown in FigureR.

NOTE: If the cutting angle varies from cut to cut, check that the bevel lock knob and the miter

lock handle are securely locked. These must be locked after making any changes in bevel

ormiter.

The chart at the end of this manual (Table 1) will assist you in selecting the proper bevel and

miter settings for common compound miter cuts. To use the chart, select the desired angleA

(Fig.R) of your project and locate that angle on the appropriate arc in the chart. From that point

follow the chart straight down to find the correct bevel angle and straight across to find the

correct miterangle.

Fig. R

Angle “A”

Set your saw to the prescribed angles and make a few trial cuts. Practice fitting the cut pieces

together until you develop a feel for this procedure and feel comfortable withit.

Example: To make a 4-sided box with 26º exterior angles (Angle A, Fig.R), use the upper right arc.

Find 26° on the arc scale. Follow the horizontal intersecting line to either side to get miter angle

setting on saw (42°). Likewise, follow the vertical intersecting line to the top or bottom to get the

bevel angle setting on the saw (18°). Always try cuts on a few scrap pieces of wood to verify the

settings on thesaw.

ENGLISH

Cutting Base Molding (Fig. S)

ALWAYS MAKE A DRY RUN WITHOUT POWER BEFORE MAKING ANYCUTS.

Straight 90° cuts:

Position the wood against the fence and hold it in place as shown in FigureS. Turn on the saw,

allow the blade to reach full speed and lower the arm smoothly through thecut.

Fig. S

Cutting Base Molding up to 6.75" (171 mm) Vertically Against

the Fence (Fig. K, S)

NOTE: Use the slide lock lever, shown in Figure K, when cutting base molding measuring from 3”

to 6.75” (76 mm to 171 mm) high vertically against thefence.

Position material as shown in FigureS.

All cuts should be made with the back of the molding against the fence and with the bottom of

the molding against thetable.

Cutting Crown Molding

Your miter saw is better suited to the task of cutting crown molding than any tool made. In order

to fit properly, crown molding must be compound mitered with extremeaccuracy.

The two flat surfaces on a given piece of crown molding are at angles that, when added together,

equal exactly 90°. Most, but not all, crown molding has a top rear angle (the section that fits flat

against the ceiling) of 52° and a bottom rear angle (the part that fits flat against the wall) of38°.

Your miter saw has special pre-set miter latch points at 31.6° left and right for cutting crown

molding at the proper angle and bevel stop pawls at 33.9° left and right. There is also a mark on

the bevel scale at 33.9°.

The chart below gives the proper settings for cutting crown molding. (The numbers for the miter

and bevel settings are very precise and are not easy to accurately set on your saw.) Since most

rooms do not have angles of precisely 90º, you will have to fine tune your settingsanyway.

PRETESTING WITH SCRAP MATERIAL IS EXTREMELY IMPORTANT!

When setting bevel and miter angles for all compound miters, remember that:

The angles presented for crown moldings are very precise and difficult to set exactly. Since they

can easily shift slightly and very few rooms have exactly square corners, all settings should be tested

on scrapmolding.

PRETESTING WITH SCRAP MATERIAL IS EXTREMELY IMPORTANT!

Alternative Method for Cutting Crown Molding (Fig. U)

Place the molding on the table at an angle between the sliding fence

10

and the saw

table

16

, as shown in FigureU. Use of the crown molding fence accessory (DW7084) is highly

recommended because of its degree of accuracy and convenience. The crown molding fence

accessory is available for purchase from your localdealer.

The advantage to cutting crown molding using this method is that no bevel cut is required.

Minute changes in the miter angle can be made without affecting the bevel angle. This way,

when corners other than 90° are encountered, the saw can be quickly and easily adjusted for

them. Use the crown molding fence accessory to maintain the angle at which the molding will

be on thewall.

Fig. U

Instructions for Cutting Crown Molding Angled Between the

Fence and Base of the Saw for All Cuts

1. Angle the molding so the bottom of the molding (part which goes against the wall when

installed) is against the fence and the top of the molding is resting on the base of the saw, as

shown in FigureU.

2. The angled “flats” on the back of the molding must rest squarely on the fence and base of

thesaw.

Special Cuts

NEVER MAKE ANY CUT UNLESS THE MATERIAL IS SECURED ON THE TABLE AND AGAINST

THEFENCE.

Aluminum Cutting (Fig. A, V, W)

ALWAYS USE THE APPROPRIATE SAW BLADE MADE ESPECIALLY FOR CUTTING ALUMINUM. These

are available at your local

DeWALT

retailer or

DeWALT

service center. Certain workpieces, due to

their size, shape or surface finish, may require the use of a clamp or fixture to prevent movement

during the cut. Position the material so that you will be cutting the thinnest cross section, as

shown in FigureV. FigureW illustrates the wrong way to cut these extrusions.

Use a stick wax cutting lubricant when cutting aluminum. Apply the stick wax directly to the saw

blade

38

before cutting. Never apply stick wax to a movingblade.

The wax, available at most hardware stores and industrial mill supply houses, provides proper

lubrication and keeps chips from adhering to theblade.

Be sure to properly secureworkpiece.

ENGLISH

Fig. W

WRONG

Refer to Saw Blades under Accessories for correct sawblade.

Bowed Material (Fig. X, Y)

When cutting bowed material always position it as shown in FigureX and never like that

shown in Figure Y. Positioning the material incorrectly will cause it to pinch the blade near the

completion of thecut.

Fig. X

Fig. Y

Cutting Plastic Pipe or Other Round Material

Plastic pipe can be easily cut with your saw. It should be cut just like wood and CLAMPED OR

HELD FIRMLY TO THE FENCE TO KEEP IT FROM ROLLING. This is extremely important when

making anglecuts.

Cutting Large Material (Fig. Z)

Occasionally you will encounter a piece of wood a little too large to fit beneath the lower guard.

If this occurs, simply place your right thumb on the upper side of the guard and roll the guard up

just enough to clear the workpiece, as shown in Figure Z. Avoid doing this as much as possible,

but if need be, the saw will operate properly and make the bigger cut. NEVER TIE, TAPE, OR

OTHERWISE HOLD THE GUARD OPEN WHEN OPERATING THISSAW.

Fig. Z

MAINTENANCE



WARNING: To reduce the risk of serious personal injury, turn unit off and disconnect

it from power source before making any adjustments or removing/installing

attachments or accessories. An accidental start-up can causeinjury.



WARNING: To reduce the risk of serious personal injury, DO NOT touch the sharp

points on the blade with fingers or hands while performing anymaintenance.

DO NOT use lubricants or cleaners (particularly spray or aerosol) in the vicinity of the plastic

guard. The polycarbonate material used in the guard is subject to attack by certainchemicals.

1. All bearings are sealed. They are lubricated for life and need no furthermaintenance.

2. Periodically clean all dust and wood chips from around AND UNDER the base and the

rotary table. Even though slots are provided to allow debris to pass through, some dust

willaccumulate.

3. The brushes are designed to give you several years of use. To replace the brushes return the

tool to the nearest service center for repair. A list of service center locations is packed with

yourtool.

Removing and Replacing Belt (Fig. AA)

The belt is designed to last the life of the tool. However, abuse of the tool could cause the belt

tofail.

If the blade does not turn when the motor is running, the belt has failed. To inspect or replace the

belt, remove the belt cover screws

53

. Remove the belt cover

59

. Inspect the ribs of the belt for

wear or failure. Check belt tension by squeezing the belt as shown in Figure AA. The belt halves

should almost touch when squeezing firmly with the thumb and index finger. To adjust the tension,

loosen, but do not remove, the four crosshead screws shown. Then rotate the set screw on the

top of the motor plate casting until the proper tension is achieved. Tighten the four screws

securely and replace the belt cover.

NOTICE: Overtightening the belt will cause premature motorfailure.

Worklight Cleaning

For the best worklight performance, perform the following maintenanceregularly.

1. Carefully clean sawdust and debris from worklight lens with a cotton swab.

2. DO NOT use solvents of any kind, they may damage the lens.

ENGLISH

3. Dust build-up can block the worklight and prevent it from accurately indicating the line

ofcut.

4. Follow miter saw’s instruction manual to remove and install blade.

5. With blade removed from saw, clean pitch and build-up from blade. Pitch and debris can

interfere with the worklight and prevent it from accurately indicating the line ofcut.

AVERTISSEMENTS DE SÉCURITÉ GÉNÉRAUX POUR LES OUTILS

ÉLECTRIQUES



AVERTISSEMENT: lisez tous les avertissements de sécurité, toutes les instructions,

les illustrations et les caractéristiques fournis avec cet outil électrique. Ne pas suivre

toutes les instructions comprises aux présentes peut conduire à un choc électrique, un

incendie et/ou des blessuresgraves.

CONSERVER TOUS LES AVERTISSEMENTS ET TOUTES LES

DIRECTIVES POUR UN USAGE ULTÉRIEUR

Le terme « outil électrique » cité dans les avertissements se rapporte à votre outil électrique à

alimentation sur secteur (avec fil) ou par piles (sansfil).

1) Sécurité du lieu de travail

a ) Tenir l’aire de travail propre et bien éclairée. Les lieux encombrés ou sombres sont

propices auxaccidents.

b ) Ne pas faire fonctionner d’outils électriques dans un milieu déflagrant, tel qu’en

présence de liquides, de gaz ou de poussières inflammables. Les outils électriques

produisent des étincelles qui pourraient enflammer la poussière ou lesvapeurs.

c ) Éloigner les enfants et les personnes à proximité pendant l’utilisation d’un outil

électrique. Une distraction pourrait en faire perdre la maîtrise à l’utilisateur.

2) Sécurité en matière d’électricité

a ) Les fiches des outils électriques doivent correspondre à la prise. Ne jamais modifier

la fiche d’aucune façon. Ne jamais utiliser de fiche d’adaptation avec un outil

électrique mis à la terre. Le risque de choc électrique sera réduit par l’utilisation de fiches

non modifiées correspondant à laprise.

b ) Éviter tout contact physique avec des surfaces mises à la terre comme des tuyaux,

des radiateurs, des cuisinières et des réfrigérateurs. Le risque de choc électrique est plus

élevé si votre corps est mis à laterre.

c ) Ne pas exposer les outils électriques à la pluie ou à l’humidité. La pénétration de l’eau

dans un outil électrique augmente le risque de chocélectrique.

d ) Ne pas utiliser le cordon de façon abusive. Ne jamais utiliser le cordon pour

transporter, tirer ou débrancher un outil électrique. Tenir le cordon éloigné de

la chaleur, de l’huile, des bords tranchants et des pièces mobiles. Les cordons

endommagés ou enchevêtrés augmentent les risques de chocélectrique.

e ) Pour l’utilisation d’un outil électrique à l’extérieur, se servir d’une rallonge

convenant à cette application. L’utilisation d’une rallonge conçue pour l’extérieur réduira

les risques de chocélectrique.

f ) S’il est impossible d’éviter l’utilisation d’un outil électrique dans un endroit

humide, brancher l’outil dans une prise ou sur un circuit d’alimentation dotés d’un

disjoncteur de fuite à la terre (GFCI). L’utilisation de ce type de disjoncteur réduit les

risques de chocélectrique.

3) Sécurité personnelle

a ) Être vigilant, surveiller le travail effectué et faire preuve de jugement lorsqu’un

outil électrique est utilisé. Ne pas utiliser d’outil électrique en cas de fatigue ou sous

l’influence de drogues, d’alcool ou de médicaments. Un simple moment d’inattention

en utilisant un outil électrique peut entraîner des blessures corporellesgraves.

b ) Utiliser des équipements de protection individuelle. Toujours porter une protection

oculaire. L’utilisation d’équipements de protection comme un masque antipoussière, des

chaussures antidérapantes, un casque de sécurité ou des protecteurs auditifs lorsque la

situation le requiert réduira les risques de blessurescorporelles.

c ) Empêcher les démarrages intempestifs. S’assurer que l’interrupteur se trouve à la

position d’arrêt avant de relier l’outil à une source d’alimentation et/ou d’insérer

un bloc-piles, de ramasser ou de transporter l’outil. Transporter un outil électrique alors

que le doigt repose sur l’interrupteur ou brancher un outil électrique dont l’interrupteur est à

la position de marche risque de provoquer unaccident.

d ) Retirer toute clé de réglage ou clé avant de démarrer l’outil. Une clé ou une clé

de réglage attachée à une partie pivotante de l’outil électrique peut provoquer des

blessurescorporelles.

e ) Ne pas trop tendre les bras. Conserver son équilibre en tout temps. Cela permet de

mieux maîtriser l’outil électrique dans les situationsimprévues.

f ) S’habiller de manière appropriée. Ne pas porter de vêtements amples ni de

bijoux. Garder les cheveux, les vêtements et les gants à l’écart des pièces mobiles.

Les vêtements amples, les bijoux ou les cheveux longs risquent de rester coincés dans les

piècesmobiles.

g ) Si des composants sont fournis pour le raccordement de dispositifs de

dépoussiérage et de ramassage, s’assurer que ceux-ci sont bien raccordés et

utilisés. L’utilisation d’un dispositif de dépoussiérage peut réduire les dangers engendrés par

lespoussières.

h ) Ne pas laisser votre connaissance acquise suite l’utilisation fréquente des outils

vous permettre de baisser la garde et ignorer les principes de sécurité de l’outil. Un

acte irréfléchi peut causer une blessure grave en une fraction deseconde.

4) Utilisation et entretien d’un outil électrique

a ) Ne pas forcer un outil électrique. Utiliser l’outil électrique approprié à l’application.

L’outil électrique approprié effectuera un meilleur travail, de façon plus sûre et à la vitesse

pour laquelle il a étéconçu.

b ) Ne pas utiliser un outil électrique dont l’interrupteur est défectueux. Tout outil

électrique dont l’interrupteur est défectueux est dangereux et doit êtreréparé.

c ) Débrancher la fiche de la source d’alimentation et/ou du bloc-piles de l’outil

électrique avant de faire tout réglage ou changement d’accessoire ou avant de

ranger l’outil. Ces mesures préventives réduisent les risques de démarrage accidentel de

l’outilélectrique.

d ) Ranger les outils électriques hors de la portée des enfants et ne permettre à

aucune personne n’étant pas familière avec un outil électrique ou son mode

d’emploi d’utiliser cet outil. Les outils électriques deviennent dangereux entre les mains

d’utilisateursinexpérimentés.

e ) Entretien des outils électriques. Vérifier si les pièces mobiles sont mal alignées ou

coincées, si des pièces sont brisées ou présentent toute autre condition susceptible

de nuire au bon fonctionnement de l’outil électrique. En cas de dommage, faire

réparer l’outil électrique avant toute nouvelle utilisation. Beaucoup d’accidents sont

causés par des outils électriques malentretenus.

f ) S’assurer que les outils de coupe sont aiguisés et propres. Les outils de coupe bien

entretenus et affûtés sont moins susceptibles de se coincer et sont plus faciles àmaîtriser.

g ) Utiliser l’outil électrique, les accessoires, les forets, etc. conformément aux

présentes directives en tenant compte des conditions de travail et du travail à

effectuer. L’utilisation d’un outil électrique pour toute opération autre que celle pour

laquelle il a été conçu estdangereuse.

h ) Gardez vos mains et les surfaces de prise sèches, propres et libres de graisse et de

poussière. Les mains et les surfaces de prise glissante ne permettent pas la manutention et

le contrôle sécuritaires de l’outil dans les situationsimprévues.

5) Réparation

a ) Faire réparer l’outil électrique par un réparateur professionnel en n’utilisant que

des pièces de rechange identiques. Cela permettra de maintenir une utilisation sécuritaire

de l’outilélectrique.

Consignes de sécurité propres aux scies à onglet

a ) Les scies à onglet ont été conçues pour découper le bois ou des produits similaires.

Elles ne peuvent être utilisées avec des meules à tronçonner pour découper des

matériaux ferreux tels barres, tiges, montants, etc. Les poussières abrasives pourront

enrayer les pièces mobiles comme le carter inférieur. Les étincelles provenant de la découpe

abrasive pourront brûler le carter inférieur, la plaque du trait de scie ou toute autre pièce

enplastique.

b ) Utilisez des serre-joints pour soutenir les pièces de travail lorsque possible. Si vous

soutenez la pièce de travail à la main, vous devez toujours garder votre main à au

moins 100 mm (4po) de chaque côté de la lame de la scie. Ne pas utiliser cette scie

pour couper des pièces trop petites pour être arrimées ou tenues manuellement

de façon sécuritaire. Si la main s’approche trop près de la lame, les risques de dommages

corporels par contact avec la lameaugmentent.

c ) La pièce à travailler doit être fixe et bien arrimée, ou maintenue, contre le guide

et la table. Ne jamais alimenter la pièce à travailler vers la lame ou couper à main

levée. Une pièce non maintenue ou mobile pourrait être éjectée à grande vitesse et causer

des dommagescorporels.

d ) Poussez la scie dans la pièce de travail. Ne pas tirer la scie dans la pièce de travail.

Pour faire une coupe, levez la tête de la scie et sortez-la au-dessus de la pièce de

travail sans couper, démarrez le moteur, baissez la tête de la scie et poussez la scie

dans la pièce de travail. Couper sur un coup en traction risque de faire grimper la lame

de la scie sur le dessus de la pièce de travail et projeter violemment l’assemblage de la lame

versl’utilisateur.

e ) Ne jamais laisser la main traverser la ligne de coupe, que ce soit devant ou derrière

la lame. Le fait de maintenir la pièce en croisant les bras (la maintenir du côté droit de la scie

avec la main gauche, ou inversement) est extrêmementdangereux.

f ) Ne pas atteindre l’arrière du guide avec une ou l’autre des mains plus près de

100mm (4po) de chaque côté de la lame de la scie, pour retirer les résidus de bois

ou pour toute autre raison pendant que la lame tourne. La proximité de la lame en

mouvement avec la main pourrait ne pas être évidente et poser des risques de dommages

corporelsgraves.

g ) Vérifier la pièce avant la coupe. Si la pièce est gauchie ou voilée, l’arrimer avec la

courbe externe orientée vers le guide. S’assurer systématiquement qu’il n’y a aucun

espace entre la pièce, le guide et la table le long de la ligne de coupe. Les pièces

gauchies ou voilées peuvent se tordre ou bouger et causer un grippage au niveau de

la lame en mouvement pendant la coupe. La pièce devrait être exempte de clous ou de

tout autre objetétranger.

h ) Ne pas utiliser la scie tant que la table ne sera pas débarrassée de tout outil,

débris de bois, etc., autre que la pièce à travailler. Les petits débris, morceaux de bois,

ou autres objets qui entreraient en contact avec la scie en mouvement pourraient être

éjectésviolemment.

FRANÇAIS

i ) Couper une pièce à la fois. Les pièces mises les unes sur les autres ne peuvent être arrimées

de façon adéquate et pourraient rester coincées dans la lame ou bouger pendant lacoupe.

j ) S’assurer que la scie à onglet est montée ou installée sur une surface plane et ferme

avant son utilisation. Une surface plane et ferme réduit les risques d’instabilité de la scie

àonglet.

k ) Planifier le travail. À chaque changement de réglage d’angle de biseau ou d’onglet,

vérifier que le guide n’interfèrera pas avec la lame et le dispositif de protection.

Alors que l’outil n’est pas en ‘”MARCHE” et qu’aucune pièce ne se trouve sur la table, déplacer

la lame tout du long pour simuler une coupe complète pour s’assurer qu’il n’y aura aucune

interférence ou risque de couper leguide.

l ) Offrir un soutien adéquat, tel que rallonges de table, chevalets, etc., pour toute

pièce plus longue ou plus large que la table de l’établi. Les pièces plus longues ou plus

larges que la table de scie à onglet pourraient tomber si elles ne sont pas soigneusement

soutenues. Si c’était le cas, aussi bien pour la pièce ou la découpe, elles pourraient soulever le

carter inférieur ou être rejetées par la lame enmouvement.

m ) Ne pas utiliser un autre individu comme substitut à une rallonge ou à un support

additionnel. Le soutien instable de la pièce pourra gripper la lame ou faire bouger la pièce

pendant la découpe, et attirer l’utilisateur et son aide vers la lame enmouvement.

n ) La découpe ne doit pas être coincée ou appuyée en aucune façon contre la lame en

mouvement. Si elle était coincée (à l’aide de butées longitudinales), la découpe pourrait être

bloquée contre la lame et rejetéeviolemment.

o ) Utiliser systématiquement un serre-joint ou un dispositif de fixation pour soutenir

correctement des matériaux arrondis comme les barreaux ou la tubulure. Les

barreaux ont tendance à rouler pendant la coupe, gripper la lame et attirer la pièce et la

main vers lalame.

p ) Laisser la lame tourner à plein régime avant de la mettre en contact avec la pièce.

Cela réduira les risques que la pièce soitéjectée.

q ) Si la pièce ou la lame se grippait, arrêter la scie à onglet. Attendre l’arrêt complet de

toutes les pièces mobiles, déconnecter l’outil du secteur et/ou retirer le bloc-piles. Et

alors seulement, libérer le matériau coincé. Le fait de continuer à scier alors que la pièce

est grippée pourra causer la perte de contrôle de la scie à onglet et l’endommager.

r ) Une fois la coupe terminée, relâchez l’interrupteur, maintenir la tête de scie

abaissée et attendre l’arrêt complet de la lame avant de retirer la découpe.

Approcher la main d’une lame au ralenti estdangereux.

s ) Maintenir fermement la poignée pour effectuer une coupe partielle ou pour libérer

l’interrupteur alors que la tête de scie n’est pas encore complètement abaissée. Le

freinage de la scie pourrait abaisser soudainement la tête de scie, et poser des risques de

dommagescorporels.

Règles de sécurité additionnelles relatives aux scies à onglet



AVERTISSEMENT : ne pas laisser une bonne connaissance de l’outil (acquise par l’utilisation

fréquente de la scie) prendre préséance sur les règles de sécurité. Toujours se souvenir qu’une

fraction de seconde d’imprudence est suffisante pour infliger de gravesblessures.



AVERTISSEMENT: ne jamais modifier l’outil électrique ou toute pièce de celui-ci. Cela

pourrait entraîner des dommages matériels ou des blessurescorporelles.

• NE PAS UTILISER CETTE MACHINE tant qu’elle n’est pas complètement assemblée et installée,

conformément aux instructions données. Une machine incorrectement assemblée pose des

risques de dommages corporelsgraves.

• DEMANDER CONSEIL à un supérieur, un instructeur, ou à toute autre personne qualifiée, si

l’on n’est pas complètement familier avec l’utilisation de cette machine. Le savoir est source

desécurité.

• SE CONFORMER AUX NORMES DU CODE EN MATIÈRE DE CÂBLAGE et connexions

électriques pour prévenir tout risque de décharges électriques ou d’électrocution. Protéger la ligne

électrique avec un fusible temporisé d’au moins 15 ampères ou undisjoncteur.

• S’ASSURER QUE la lame tourne dans le bon sens. Les dents de la lame devraient pointer dans le

sens de rotation indiqué sur lascie.

• RESSERRER TOUS LES LEVIERS DE VERROUILLAGE, boutons et autres leviers avant toute

utilisation. Les dispositifs de fixation lâches posent des risques d’éjection rapide et violente de la

pièce àtravailler.

• S’ASSURER que l’ensemble lame et serre-lames est propre, que les côtés encastrés des serre-

lames se trouvent contre la lame et que la vis de l’arbre est resserrée soigneusement. Une lame

mal ou incorrectement arrimée pose des risques de dommages matériels etcorporels.

• NE PAS UTILISER LA SCIE SUR TOUTE AUTRE TENSION AUTRE QUE CELLE SPÉCIFIÉE.

Surchauffe, dommages à l’outil et dommages corporels pourraientsurvenir.

• NE RIEN BLOQUER CONTRE LE VENTILATEUR pour maintenir l’arbre de moteur. Des

dommages à l’outil et dommages corporels pourraientsurvenir.

• NE JAMAIS COUPER DES MÉTAUX MÉTAUX ou la maçonnerie. Ce genre de coupes pourrait

faire éclater les pointes au carbure de la lame et les projeter violemment posant des risques de

dommages corporelsgraves.

• NE JAMAIS PLACER LES MAINS PLUS DE 100 mm (4 po) DE LALAME.

• NE JAMAIS LAISSER AUCUNE PARTIE DU CORPS ENTRER DANS LE SILLAGE DE LA LAME

SCIE, car cela pose des risques de dommagescorporels.

• NE JAMAIS APPLIQUER DE LUBRIFIANT À LAMES SUR UNE LAME EN MOUVEMENT. Lors de

l’application du lubrifiant, les mains pourraient rencontrer la lame et provoquer des dommages

corporelsgraves.

• NE PAS approcher les mains de la lame lorsque la scie est branchée sur une source

d’alimentation. L’activation accidentelle de la lame pose des risques de dommages

corporelsgraves.

• NE JAMAIS APPROCHER LES MAINS DE LA LAME, NI AUTOUR NI DERRIÈRE. Une lame peut

causer des dommages corporelsgraves.

• NE PAS PASSER LES MAINS SOUS LA SCIE à moins qu’elle ne soit à l’arrêt et débranchée. Tout

contact avec la lame de scie pose des risques de dommagescorporels.

• ARRIMER SOIGNEUSEMENT LA MACHINE À UN SUPPORT STABLE. Les vibrations

pourraient faire glisser la machine, ou bouger ou basculer, posant des risques de dommages

corporelsgraves.

• UTILISER UNIQUEMENT DES LAMES DE SCIE À COUPE TRANSVERSALE recommandées pour

scies à onglet. Pour optimiser les résultats, ne pas utiliser de lames à pointes de carbure avec un

angle d’attaque supérieur à 7 degrés. Ne pas utiliser des lames à creux de dent profonds. Elles

pourraient changer de course et toucher le carter, et poser des risques de dommages matériels

et/ou corporelsgraves.

• UTILISER UNIQUEMENT DES LAMES DE LA TAILLE ET DU TYPE CORRECTS indiqués pour cet

outil pour prévenir tout dommage matériel et/ou corporelgrave.

• VÉRIFIER QUE LES LAMES NE COMPORTENT AUCUNE FISSURE ni aucun autre dommage

avant chaque utilisation. Une lame fissurée ou endommagée peut se casser et des morceaux

pourraient être éjectés violemment, et causer des dommages corporels graves. Changer

immédiatement toute lame fissurée ouendommagée.

• NETTOYER LA LAME ET LES SERRE-LAMES avant chaque utilisation. Leur nettoyage

permettra de vérifier qu’ils ne comportent aucun dommage. Une lame ou un serre-lame fissuré

ou endommagé peut se casser et des morceaux pourraient être éjectés violemment, et causer des

dommages corporelsgraves.

• NE PAS UTILISER DE LAMES VOILÉES. Vérifier que la lame tourne correctement et sans

vibration. Une lame qui vibre pose des risques de dommages matériels et corporelsgraves.

• NE PAS utiliser de lubrifiant ou de nettoyant (particulièrement en vaporisateur ou en aérosol)

à proximité du carter en plastique. Le matériau en polycarbonate utilisé pour le carter peut être

attaqué par certains produitschimiques.

• MAINTENIR LES DISPOSITIFS DE PROTECTION EN PLACE et en bon état demarche.

• UTILISER SYSTÉMATIQUEMENT LA PLAQUE DE TRAIT ET LA REMPLACER SI ELLE EST

ENDOMMAGÉE. De petits débris s’accumulant sous la scie pourraient interférer avec la lame de

scie et causer l’instabilité de la pièce lors de lacoupe.

• UTILISER UNIQUEMENT LES SERRE-LAMES RECOMMANDÉS POUR CET OUTIL pour

prévenir tout dommage matériel et/ou corporelgrave.

• ÉLIMINER DES ORIFICES D’AÉRATION DU MOTEUR tout débris ou sciure. Des orifices

d’aération bouchés pourraient causer la surchauffe de la machine et l’endommager. Cela

pourrait aussi provoquer un court-circuit qui poserait de risques de dommages corporelsgraves.

• NE JAMAIS VERROUILLER L’INTERRUPTEUR EN POSITION DE MARCHE (ON), car cela pose

des risques de dommages corporelsgraves.

• NE JAMAIS MONTER SUR L’OUTIL. De sérieux dommages corporels pourraient en résulter si

l’outil basculait ou en cas de contact involontaire avec l’organe decoupe.

• DES INFORMATIONS COMPLÉMENTAIRES sur la sécurité et l’utilisation correcte des

outils électriques (ex.: vidéo sécurité) sont à votre disposition auprès du Power Tool Institute

(l’Institut des outils électriques), 1300 Sumner Avenue, Cleveland, OH 44115-2851 (www.

powertoolinstitute. com). Des informations sont aussi à votre disposition auprès du National

Safety Council (Conseil National de la Sécurité), 1121 Spring Lake Drive, Itasca, IL 60143-3201. Se

reporter aux standards de l’institut: American National Standards Institute ANSI 01.1, Directives

de sécurité pour les machines à bois et à la réglementation OSHA 1910. 213 du Ministère du

travailaméricain.



AVERTISSEMENT: le fait de découper des plastiques, du bois enduit de sève ou autres

matériaux pouvant causer l’accumulation de matériaux fondus sur les pointes de lame et le

corps de lame, augmente les risques de surchauffe et de grippage lors de lacoupe.



AVERTISSEMENT: porter SYSTEMATIQUEMENT des lunettes de protection. Les lunettes

courantes NE sont PAS des lunettes de protection. Utiliser aussi un masque antipoussières si

la découpe doit en produire beaucoup. PORTER SYSTÉMATIQUEMENT UN ÉQUIPEMENT DE

SÉCURITÉ HOMOLOGUÉ:

• Protection oculaire ANSI Z87.1 (CAN/CSA Z94.3);

• Protection auditive ANSI S12.6 (S3.19);

• Protection des voies respiratoires NIOSH/OSHA/MSHA.



AVERTISSEMENT: les scies, meules, ponceuses, perceuses ou autres outils de construction

peuvent produire des poussières contenant des produits chimiques reconnus par l’État

californien pour causer cancers, malformations congénitales ou être nocifs au système

reproducteur. Parmi ces produits chimiques, on retrouve:

• Le plomb dans les peintures à base de plomb;

• La silice cristallisée dans les briques et le ciment, ou autres produits de maçonnerie; et

• L’arsenic et le chrome dans le bois ayant subi un traitementchimique.

Le risque associé à de telles expositions varie selon la fréquence à laquelle on effectue ces travaux.

Pour réduire toute exposition à ces produits: travailler dans un endroit bien aéré, en utilisant du

FRANÇAIS

matériel de sécurité homologué, tel un masque antipoussières spécialement conçu pour filtrer les

particulesmicroscopiques.

• Limiter toute exposition prolongée avec les poussières provenant du ponçage, sciage,

meulage, perçage ou toute autre activité de construction. Porter des vêtements de

protection et nettoyer à l’eau savonneuse les parties du corps exposées. Le fait de laisser

la poussière pénétrer dans la bouche, les yeux ou la peau peut favoriser l’absorption de produits

chimiquesdangereux.



AVERTISSEMENT: cet outil peut produire et/ou répandre de la poussière susceptible

de causer des dommages sérieux et permanents au système respiratoire. Utiliser

systématiquement un appareil de protection des voies respiratoires homologué par le NIOSH

ou l’OSHA. Diriger les particules dans le sens opposé au visage et aucorps.



AVERTISSEMENT: pendant l’utilisation, porter systématiquement une protection

auditive individuelle adéquate homologuée ANSI S12.6 (S3.19). Sous certaines

conditions et suivant la durée d’utilisation, le bruit émanant de ce produit pourrait contribuer

à une perte de l’acuitéauditive.

• Prendre des précautions à proximité des évents, car ils cachent des pièces mobiles.

Vêtements amples, bijoux ou cheveux longs risquent de rester coincés dans ces piècesmobiles.

• Pour la sécurité de l’utilisateur, utiliser une rallonge de calibre adéquat (AWG,

American Wire Gauge [calibrage américain normalisé des fils électriques]). Plus le calibre

est petit, et plus sa capacité est grande. Un calibre16, par exemple, a une capacité supérieure

à un calibre18. L’usage d’une rallonge de calibre insuffisant causera une chute de tension qui

entraînera perte de puissance et surchauffe. Si plus d’une rallonge est utilisée pour obtenir une

certaine longueur, s’assurer que chaque rallonge présente au moins le calibre de fil minimum.

Le tableau ci-dessous illustre les calibres à utiliser selon la longueur de rallonge et l’intensité

nominale indiquée sur la plaque signalétique. En cas de doute, utiliser le calibre suivant. Plus le

calibre est petit, plus la rallonge peut supporter decourant.



AVERTISSEMENT: GARDEZ VOS MAINS ET VOTRE CORPS HORS

DE PORTÉE DE LA TRAJECTOIRE DE LA LAME DE LA SCIE. TOUT

CONTACT AVEC LA LAME ENTRAÎNERA UNE BLESSURE GRAVE.

NE PAS UTILISER LA SCIE SANS LES PROTECTEURS EN PLACE. VÉRIFIEZ LE SYSTÈME DE

PROTECTION AFIN D’ASSURER QU’IL FONCTIONNE CORRECTEMENT. NE FAIRE AUCUN

TRAVAIL À MAIN LEVÉE. NE JAMAIS TOUCHER L’ARRIÈRE DE LA LAME DE LA SCIE

ÉTEIGNEZ L’OUTIL ET ATTENDEZ QUE LA LAME S’ARRÊTE AVANT DE DÉPLACER LA

PIÈCE DE TRAVAIL, MODIFIER LES RÉGLAGES OU DÉPLACER VOS MAINS. NE JAMAIS

RÉGLAGE AVANT CHAQUE UTILISATION. DÉBRANCHEZ L’ALIMENTATION AVANT DE

CHANGER LA LAME OU L’ENTRETIEN.

SUR LA TABLE : (À 2 ENDROITS)

Double isolation

Afin de protéger l’utilisateur contre les décharges électriques, les outils à double isolation sont

complètement recouverts de deux couches distinctes d’isolant électrique ou d’une simple

épaisseur renforcée de matière isolante. Les outils comportant ce système d’isolation ne sont

pas conçus pour être mis à la terre. L’outil est donc doté d’une prise à deux broches qui permet

d’utiliser des rallonges sans avoir à se soucier de maintenir une connexion à laterre.

REMARQUE: le fait que cet outil soit muni d’une double isolation ne signifie pas que l’utilisateur

peut cesser de respecter les consignes de sécurité qui s’imposent. L’isolation secondaire offre une

protection contre tout dommage corporel pouvant résulter d’une défaillance électrique possible

du système primaire d’isolationinterne.



ATTENTION : EN CAS DE RÉPARATION, UTILISER UNIQUEMENT DES PIÈCES DE RECHANGE

IDENTIQUES. Réparer ou remplacer les cordons d’alimentationendommagés.

Fiches polarisées

Certains appareils comportent des fiches polarisées (c’est-à-dire qu’une lame est plus large

que l’autre) afin de réduire le risque de choc électrique. Lorsqu’elle est présente, cette fiche ne

se branche que d’une seule façon dans une prise de courant polarisée. Si la fiche ne s’insère

pas totalement dans la prise de courant, l’inverser. Si elle ne s’insère toujours pas dans la prise,

demander à un électricien compétent d’installer une fiche polarisée. Ne pas remplacer lafiche.

Connexion électrique

S’assurer que votre bloc d’alimentation est compatible avec l’inscription de la plaque

signalétique. 120 volts, c.a. signifie que votre scie ne peut uniquement fonctionner qu’en courant

alternatif. Une diminution de tension de 10 pour cent ou plus risquera de provoquer une perte de

puissance et une surchauffe. Tous les outils

DeWALT

sont testés en usine. Si l’outil ne fonctionne

pas, vérifier l’alimentation.
