GENERAL SAFETY INSTRUCTIONS

WARNING! Read and understand all instructions.

Failure to follow all instructions listed below may result

in electric shock, fire and/or serious personal injury.

SAVE THESE INSTRUCTIONS

WORK AREA

• Keep your work area clean and well lit. Cluttered benches and

dark areas invite accidents.

• 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.

• Keep bystanders, children, and visitors away while operating

a power tool. Distractions can cause you to lose control.

ELECTRICAL SAFETY

• Grounded tools must be plugged into an outlet properly

installed and grounded in accordance with all codes and

ordinances. Never remove the grounding prong or modify

the plug in any way. Do not use any adapter plugs. Check

with a qualified electrician if you are in doubt as to whether

the outlet is properly grounded. If the tools should electrically

malfunction or break down, grounding provides a low resistance

path to carry electricity away from the user. Applicable only to

Class I (grounded) tools.

• Double insulated tools are equipped with a polarized plug

(one blade is wider than the other.) This plug will fit in a

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 a polarized outlet. Do not

change the plug in any way. Double insulation

eliminates

the need for the three wire grounded power cord and grounded

power supply system. Applicable only to Class II (double

insulated) tools. The DW367, DW368 and DW369 are double

insulated tools.

• Avoid body contact with grounded surfaces such as pipes,

radiators, ranges and refrigerators. There is an increased risk

of electric shock if your body is grounded.

• Don’t expose power tools to rain or wet conditions. Water

entering a power tool will increase the risk of electric shock.

• Do not abuse the cord. Never use the cord to carry the

tools or pull the plug from an outlet. Keep cord away from

English

heat, oil, sharp edges or moving parts. Replace damaged

cords immediately. Damaged cords increase the risk of electric

shock.

• When operating a power tool outside, use an outdoor

extension cord marked “W-A” or “W.” These cords are rated

for outdoor use and reduce the risk of electric shock. When using

an extension cord, be sure to use one heavy enough to carry the

current your product will draw. An undersized cord will cause a

drop in line voltage resulting in loss of power and overheating.

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 smaller the gauge number, the heavier

the cord.

PERSONAL SAFETY

• Stay alert, watch what you are doing and use common

sense when operating a power tool. Do not use tool while

tired or under the influence of drugs, alcohol, or medication.

A moment of inattention while operating power tools may result

in serious personal injury,

• Dress properly. Do not wear loose clothing or jewelry.

Contain long hair. Keep your hair, clothing, and gloves away

from moving parts. Loose clothes, jewelry, or long hair can be

caught in moving parts. Air vents often cover moving parts and

should also be avoided.

• Avoid accidental starting. Be sure switch is off before

plugging in. Carrying tools with your finger on the switch or

plugging in tools that have the switch on invites accidents.

• Remove adjusting keys or wrenches before turning the tool

on. A wrench or a key that is left attached to a rotating part of

the tool may result in personal injury.

• Do not overreach. Keep proper footing and balance at all

times. Proper footing and balance enables better control of the

tool in unexpected situations.

• Use safety equipment. Always wear eye protection. Dust

mask, non-skid safety shoes, hard hat, or hearing protection

must be used for appropriate conditions.

TOOL USE AND CARE

• Use clamps or other practical way to secure and support the

workpiece to a stable platform. Holding the work by hand or

against your body is unstable and may lead to loss of control.

• Do not force tool. Use the correct tool for your application.

The correct tool will do the job better and safer at the rate for

which it is designed.

• Do not use tool if switch does not turn it on or off. Any tool

that cannot be controlled with the switch is dangerous and must

be repaired.

• Disconnect the plug from the power source before making

any adjustments, changing accessories, or storing the tool.

Such preventative safety measures reduce the risk of starting

the tool accidentally.

• Store idle tools out of reach of children and other untrained

persons. Tools are dangerous in the hands of untrained users.

• Maintain tools with care. Keep cutting tools sharp and

clean. Properly maintained tools, with sharp cutting edges are

less likely to bind and are easier to control.

English

• Check for misalignment or binding of moving parts, breakage

of parts, and any other condition that may affect the tools

operation. If damaged, have the tool serviced before using.

Many accidents are caused by poorly maintained tools.

• Use only accessories that are recommended by the

manufacturer for your model. Accessories that may be

suitable for one tool, may become hazardous when used on

another tool.

SERVICE

• Tool service must be performed only by qualified repair

personnel. Service or maintenance performed by unqualified

personnel could result in a risk of injury.

• When servicing a tool, use only identical replacement

parts. Follow instructions in the maintenance section of

this manual. Use of unauthorized parts or failure to follow

maintenance instructions may create a risk of electric shock or

injury.

Additional Safety Instructions for

Circular Saws

DANGER! Keep hands away from cutting area and blade.

Keep your second hand on auxiliary handle, or motor housing.

If both hands are holding the saw, they cannot be cut by the

blade.

WARNING: Blades coast after turn off.

• Keep your body positioned to either side of the blade, but

not in line with the saw blade. KICKBACK could cause the

saw to jump backwards (see Causes and Operator Prevention of

Kickback and KICKBACK).

• Do not reach underneath the work. The guard can not protect

you from the blade below the work.

• Check lower guard for proper closing before each use. Do

not operate saw if lower guard does not move freely and

close instantly. Never clamp or tie the lower guard into the

open position. If saw is accidentally dropped, the lower guard

may be bent. Raise the lower guard with the retracting handle and

make sure it moves freely and does not touch the blade or any

other part, at all angles and depth of cut.

• Check the operation and condition of the lower guard spring.

If the guard and the spring are not operating properly, they

must be serviced before use. Lower guard may operate

sluggishly due to damaged parts, gummy deposits, or a buildup

of debris.

• Lower guard should be retracted manually only for special

cuts such as “pocket cuts” and “compound cuts.” Raise

lower guard by retracting handle. As soon as blade enters the

material, lower guard must be released. For all other sawing,

the lower guard should be allowed to operate automatically.

• Always observe that the lower guard is covering the blade

before placing saw down on bench or floor. An unprotected,

coasting blade will cause the saw to walk backwards, cutting

whatever is in its path. Be aware of the time it takes for the blade

to stop after switch is released.

• NEVER hold piece being cut in your hands or across your

leg. It is important to support the work properly to minimize body

exposure, blade binding, or loss of control.

• Hold tool by insulated gripping surfaces when performing

an operation where the cutting tool may contact hidden

wiring or its own cord. Contact with a “live” wire will also make

exposed metal parts of the tool “live” and shock the operator.

• When ripping, always use a rip fence or straight edge guide.

This improves the accuracy of cut and reduces the chance for

blade binding.

English

• When blade is binding, or when interrupting a cut for any

reason, release the trigger and hold the saw motionless

in the material until the blade comes to a complete stop.

Never attempt to remove the saw from the work or pull the

saw backward while the blade is in motion or kickback may

occur. Investigate and take corrective actions to eliminate the

cause of blade binding.

• When restarting a saw in the workpiece, center the saw blade

in the kerf and check that the saw teeth are not engaged into

the material. If saw blade is binding, it may walk up or kickback

from the workpiece as the saw is restarted.

• Support large panels to minimize the risk of blade pinching

and kickback. Large panels tend to sag under their own weight.

Support must be placed under the panel on both sides, near the

line of cut and near the edge of the panel.

• Do not use dull or damaged blade. Unsharpened or improperly

set blades produce narrow kerf causing excessive friction, blade

binding, and kickback.

• Blade depth and bevel adjusting locking levers must be tight

and secure before making cut. If blade adjustment shifts while

cutting, it may cause binding and KICKBACK.

• Use extra caution when making a “Pocket Cut” into existing

walls or other blind areas. The protruding blade may cut objects

that can cause kickback.

WARNING: Some dust created by power sanding, sawing,

grinding, drilling, and other construction activities contains chemicals

known 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

(CCA).

• Always use blades with correct size and shape (diamond

vs. round) arbor holes. Blades that do not match the mounting

hardware of the saw will run eccentrically, causing loss of

control.

• Never use damaged or incorrect blade washers or bolts. The

blade washers and bolt were specially designed for your saw, for

optimum performance and safety of operation.

• Avoid cutting nails. Inspect for and remove all nails from lumber

before cutting.

• Do not operate this tool for long periods of time. Vibration

caused by the operating action of this tool may cause permanent

injury to fingers, hands, and arms. Use gloves to provide extra

cushion, take frequent rest periods, and limit daily time of use.

CAUSES AND OPERATOR PREVENTION OF KICKBACK

• Kickback is a sudden reaction to a pinched, bound or misaligned

saw blade, causing an uncontrolled saw to lift up and out of the

workpiece toward the operator.

• When the blade is pinched or bound tightly by the kerf closing

down, the blade stalls and the motor reaction drives the unit

rapidly back toward the operator.

• If the blade becomes twisted or misaligned in the cut, the teeth

at the back edge of the blade can dig into the top surface of the

wood causing the blade to climb out of the kerf and jump back

toward operator.

• Kickback is the result of tool misuse and/or incorrect operating

procedures or conditions and can be avoided by taking proper

precautions as given below:

• Maintain a firm grip with both hands on the saw and position

your body and arm to allow you to resist kickback forces.

Kickback forces can be controlled by the operator, if proper

precautions are taken.

English

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 disburse 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 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 repiratory protection.

WARNING: When cutting into walls, floors or wherever live

electrical wires may be encountered, DO NOT TOUCH ANY METAL

PARTS OF THE TOOL! Hold the tool only by insulated grasping

surfaces to prevent electric shock if you cut into a live wire.

TO INSTALL THE BLADE (FIG. 1–4)

1. Place inner clamp washer (G) on saw spindle with the large flat

surface facing out toward the blade.

2. Retract the lower blade guard (F) and place blade on saw spindle

against the inner clamp washer, making sure that the blade will

rotate in the proper direction (the direction of the rotation arrow

on the saw blade and the teeth must point in the same direction

as the direction of rotation arrow on the saw). Do not assume that

the printing on the blade will always be facing you when properly

installed. When retracting the lower blade guard to install the

blade, check the condition and operation of the lower blade guard

to assure that it is working properly. Make sure it moves freely

and does not touch the blade or any other part, in all angles and

depths of cut.

3. Place outer clamp washer (H) on saw spindle with the large flat

surface against the blade and the wording on the outer clamp

washer facing you.

4. Thread blade clamping screw (E) into saw spindle by hand

(screw has right-hand threads and must be turned clockwise to

tighten).

5. Depress the blade lock (I) while turning the saw spindle with the

blade wrench until the blade lock engages and the blade stops

rotating.

6. Tighten the blade clamping screw firmly with the blade wrench.

NOTE: Never engage the blade lock while saw is running, or engage

in an effort to stop the tool. Never turn the saw on while the blade

lock is engaged. Serious damage to your saw will result.

TO REPLACE THE BLADE

1. To loosen the blade clamping screw (E), depress the blade lock

(I) and turn the saw spindle with the blade wrench until the blade

lock engages and the blade stops rotating. With the blade lock

engaged, turn the blade clamping screw counterclockwise with

SPINDLE

the blade wrench (screw has right-hand threads and must be

turned counterclockwise to loosen).

2. Remove the blade clamping screw (E) and outer clamp washer

(H) only. Remove old blade.

3. Clean any sawdust that may have accumulated

in the guard or clamp washer area and check

the condition and operation of the lower blade

guard as previously outlined. Do not lubricate

this area.

4. Select the proper blade for the application

(see Blades). Always use blades that are the

correct size (diameter) with the proper size

and shape center hole for mounting on the

saw spindle. Always assure that the maximum

recommended speed (rpm) on the saw blade

meets or exceeds the speed (rpm) of the saw.

5. Follow steps 2 through 6 under To Install the Blade, making

sure that the blade will rotate in the proper direction.

LOWER BLADE GUARD

WARNING: The lower blade guard is a safety feature which

reduces the risk of serious personal injury. Never use the saw if

the lower guard is missing, damaged, misassembled or not

working properly. Do not rely on the lower blade guard to protect

you under all circumstances. Your safety depends on following

all warnings and precautions as well as proper operation of the

saw. Check lower guard for proper closing before each use as

outlined in Additional Safety Rules for Circular Saws. If the

lower blade guard is missing or not working properly, have the

saw serviced before using. To assure product safety and

reliability, repair, maintenance and adjustment should be

performed by an authorized service center or other qualified

service organization, always using identical replacement

parts.

English

Cutting Depth Adjustment (Fig. 5, 6)

WARNING: To reduce the risk of serious personal injury,

turn tool off and disconnect tool from power source before

making any adjustments or removing/installing attachments or

accessories.

1. Hold the saw firmly. Raise the depth adjustment lever (J) to

loosen and move shoe to obtain the desired depth of cut,

as shown. Make sure the depth adjustment lever has been

retightened (lowered) before operating the saw.

2. Your saw is equipped with a carbide tipped saw blade for long life

and efficient cutting.

3. Setting the saw at the proper cutting depth keeps blade friction

to a minimum, removes sawdust from between the blade teeth,

results in cooler, faster sawing and reduces the chance of

kickback. Align the appropriate mark on the depth adjustment

strap with triangle on the upper blade guard (K). Your depth is

set.

FIG. 5

FIG. 6

4. For the most efficient cutting action using a carbide tipped saw

blade, set the depth adjustment so that about one half of a tooth

projects below the surface of the wood to be cut.

5. A method of checking for the correct cutting depth is shown in

Figure 6. Lay a piece of the material you plan to cut along the

side of the blade, as shown in the figure, and observe how much

tooth projects beyond the material.

Bevel Angle Adjustment (Fig. 7, 8)

WARNING: To reduce the risk of serious personal injury,

turn tool off and disconnect tool from power source before

making any adjustments or removing/installing attachments or

accessories.

The full range of bevel adjustment on the DW367 is 0 to 50 degrees.

The pivot bracket is graduated in 5 degree increments.

On the DW368 and DW369, the full range of bevel adjustment is

0 to 56 degrees. The pivot bracket is graduated in increments of

1 degree.

There is a bevel angle adjustment mechanism (M) consisting of a

quadrant with a pointer (N) and a lever (L) on the front of the saw.

The DW367 has a bevel stop at 45 degrees. To set the bevel at an

angle greater than 45 degrees, tilt the shoe to 45 degrees, then slide

the knob and bolt into the upper slot. When you reach the desired

angle, tighten the knob.

The DW368 and DW369 are equipped with a bevel detent feature.

As you tilt the shoe you will hear a click and feel the shoe stop at both

22.5 and 45 degrees. If either of these is the desired angle, retighten

the lever (L) by lowering it. If you desire another angle, continue

tilting the shoe until the pointer aligns with the desired mark.

Kerf Indicator (Fig. 9)

The front of the saw shoe has a kerf indicator for vertical and bevel

cutting. This indicator enables you to guide the saw along cutting

lines penciled on the material being cut. The indicator lines up with

the left (inner) side of the saw blade, which makes the slot or "kerf"

cut by the moving blade fall to the right of the indicator. The ribs

on the front of the DW368 and DW369 shoe are at 1/4" (6.35 mm)

spacing. The notches on the front of the shoe are at 1/2" (13 mm)

intervals.

OPERATION

WARNING: To reduce the risk of serious personal injury,

turn tool off and disconnect tool from power source before

making any adjustments or removing/installing attachments or

accessories.

Switch (Fig. 1)

Pull the trigger switch (B) to turn the motor on. Releasing the trigger

turns the motor off. This tool has no provision to lock the switch in the

on position, and the tool should never be locked on in any way.

English

Workpiece Support

Figures 10 and 12 show proper sawing position. Figures 11 and 13

show an unsafe condition. Hands should be kept away from cutting

area, and power cord is positioned clear of the cutting area so that

it will not get caught or hung up on the work.

To avoid kickback, DO support board or panel NEAR the cut,

(Fig. 10 and 12). DON’T support board or panel away from the cut

(Fig. 11 and 13). When operating the saw, keep the cord away from

the cutting area and prevent it from becoming hung up on the work

piece.

FIG. 12

FIG. 10

FIG. 11

FIG. 13

WARNING: It is important to support the work properly and to hold

the saw firmly to prevent loss of control which could cause personal

injury; Figure 12 illustrates typical hand support of the saw.

ALWAYS DISCONNECT SAW BEFORE MAKING ANY ADJUST-

MENTS! Place the work with its “good” side - the one on which

appearance is most important - down. The saw cuts upward, so any

splintering will be on the work face that is up when you saw it.

English

Cutting

Support the work so that the waste will be on your right. Place the

wider portion of the saw shoe on that part of the work piece which

is solidly supported, not on the section that will fall off when the cut

is made. As examples, Figure 12 illustrates the RIGHT way to cut off

the end of a board, and Figure 13 the WRONG way. Always clamp

work. Don’t try to hold short pieces by hand! Remember to support

cantilevered and overhanging material. Use caution when sawing

material from below.

Be sure that the saw is up to full speed before blade contacts

material to be cut. Starting the saw with blade against material to be

cut or pushed forward into kerf can result in kickback.

Push the saw forward at a speed which allows the blade to cut

without laboring. Hardness and toughness can vary even in the

same piece of material, and knotty or damp sections can put a heavy

load on the saw. When this happens, push the saw more slowly, but

hard enough to keep it working without much decrease in speed.

Kickback

When the saw blade becomes pinched or twisted in the cut, kickback

can occur. The saw is thrust rapidly back toward the operator. When

the blade is pinched or bound tightly by the kerf closing down, the

blade stalls and the motor reaction drives the unit backward. When

the blade becomes twisted or misaligned in the cut, the teeth at

the back edge of the blade can dig into the top surface of the wood

causing the blade to climb out of the kerf and jump back toward the

operator.

Kickback is more likely to occur when any of the following conditions

exist.

1. IMPROPER WORKPIECE SUPPORT

A. Sagging or improper lifting of the cut off piece can cause

pinching of the blade and lead to kickback (Fig. 11).

B. Cutting through material supported at the outer ends only

can cause kickback. As the material weakens it sags, closing

down the kerf and pinching the blade.

C. Cutting off a cantilevered or overhanging piece of material

from the bottom up in a vertical direction can cause kickback.

The falling cut off piece can pinch the blade.

D. Cutting off long narrow strips (as in ripping) can cause

kickback. The cut off strip can sag or twist closing the kerf and

pinching the blade.

E. Snagging the lower guard on a surface below the material

being cut momentarily reduces operator control. The saw

can lift partially out of the cut increasing the chance of blade

twist.

2. IMPROPER DEPTH OF CUT SETTING ON SAW

To make the most efficient cut, the blade should protrude only

far enough to expose 1/2 of a tooth as shown in figure 5. This

allows the shoe to support the blade and minimizes twisting and

pinching in the material. See the section titled Cutting Depth

Adjustment.

3. BLADE TWISTING (MISALIGNMENT IN CUT)

A. Pushing harder to cut through a knot, a nail, or a hard grain

area can cause the blade to twist.

B. Trying to turn the saw in the cut (trying to get back on the

marked line) can cause blade twist.

C. Over-reaching or operating the saw with poor body control

(out of balance), can result in twisting the blade.

D. Changing hand grip or body position while cutting can result

in blade twist.

E. Backing up the saw to clear blade can lead to twist if it is not

done carefully.

4. MATERIALS THAT REQUIRE EXTRA ATTENTION

A. Wet lumber

English

B. Green lumber (material freshly cut or not kiln dried)

C. Pressure treated lumber (material treated with preservatives

or anti-rot chemicals)

5. USE OF DULL OR DIRTY BLADES

Dull blades cause increased loading of the saw. To compensate,

an operator will usually push harder which further loads the

unit and promotes twisting of the blade in the kerf. Worn blades

may also have insufficient body clearance which increases the

chance of binding and increased loading.

6. LIFTING THE SAW WHEN MAKING BEVEL CUTS

Bevel cuts require special operator attention to proper cutting

techniques – especially guidance of the saw. Both blade angle

to the shoe and greater blade surface in the material increase

the chance for binding and misalignment (twist) to occur.

7. RESTARTING A CUT WITH THE BLADE TEETH JAMMED

AGAINST THE MATERIAL

The saw should be brought up to full operating speed before

starting a cut or restarting a cut after the unit has been stopped

with the blade in the kerf. Failure to do so can cause stalling and

kickback.

Any other conditions which could result in pinching, binding,

twisting, or misalignment of the blade could cause kickback. Refer

to Additional Safety Instructions and Operation for procedures and

techniques that will minimize the occurrence of kickback.

MAINTENANCE

WARNING: To reduce the risk of serious personal injury,

turn tool off and disconnect tool from power source before

making any adjustments or removing/installing attachments or

accessories.

Cleaning

WARNING: Blow dirt and dust out of all air vents with clean, dry

air at least once a week. To minimize the risk of eye injury, always

wear ANSI Z87.1 approved eye protection when performing this.

WARNING: Never use solvents or other harsh chemicals for

cleaning the non-metallic parts of the tool. These chemicals may

weaken the plastic materials used in these parts. Use a cloth

dampened only with water and mild soap. Never let any liquid get

inside the tool; never immerse any part of the tool into a liquid.

Lubrication

Self lubricating ball and roller bearings are used in the tool and

relubrication is not required. However, it is recommended that, once

a year, you take or send the tool to a service center for a thorough

cleaning, inspection and lubrication of the gear case.

Electric Brake (DW369 Only)

Your saw has an automatic electric brake which is designed to stop

the blade from coasting in about two seconds, after you release the

trigger switch. It is useful when making certain cuts in wood where

a coasting blade would result in a wide, imprecise cut.

Occasionally, the brake will not function properly and won’t stop the

saw in the 2 seconds discussed above. If this condition persists,

turn the saw on and off four or five times. If the brake still does

not stop the blade in about 2 seconds, the problem may be worn

brushes. Replace the brushes as described below and try the

saw again. If the problem still persists, have the tool serviced at a

EWALT certified service center.

Repairs

To assure product SAFETY and RELIABILITY, repairs, maintenance

and adjustment should be performed by a D

EWALT factory service

center, a D

EWALT authorized service center or other qualified

English

service personnel. Always use identical replacement parts. (Refer to

Brushes for brush replacement information.)

Brushes

WARNING: To reduce the risk of serious personal injury,

turn tool off and disconnect tool from power source before

making any adjustments or removing/installing attachments or

accessories.

Inspect carbon brushes regularly by unplugging tool, removing the

end cap and withdrawing the brush assembly. Keep brushes clean

and sliding freely in their guides. Always replace a used brush in the

same orientation in the holder as it was prior to removal. Carbon

brushes have varying symbols stamped into their sides, and if either

brush is worn down to the line closest to the spring, the brushes

must be replaced. Use only identical D

EWALT brushes. New brush

assemblies are available at your local service center. Always replace

the end cap after inspecting or servicing brushes. The tool should

be allowed to “run in” (run at no load without a blade) for 5 minutes

before use to seat new brushes.

While “running in” DO NOT TIE, TAPE, OR OTHERWISE LOCK THE

TRIGGER SWITCH ON. HOLD BY HAND ONLY.

Shoe Adjustment

WARNING: To reduce the risk of serious personal injury,

turn tool off and disconnect tool from power source before

making any adjustments or removing/installing attachments or

accessories.

Your shoe has been factory set to assure that the blade is perpen-

dicular to the shoe. If after extended use, you need to re-align the

blade follow the directions below:

ADJUSTING FOR 90 DEGREE CUTS

1. Return the saw to 0 degrees bevel.

2. Place the saw on its side, and retract the lower guard.

FIG. 14

3. Loosen the bevel adjustment lever (L). Place a square against

the blade and the shoe as shown in Figure 14.

4. Using a hex wrench, turn the set screw on the underside of the

shoe until the blade and the shoe are both in flush contact with

the square. Retighten the bevel adjustment lever.

ADJUSTING BEVEL ADJUSTMENT AND DEPTH

ADJUSTMENT LEVERS

It may be desirable to adjust the depth adjustment lever or the bevel

adjustment lever. They may loosen in time and hit the shoe before

tighten ing. To tighten the levers, follow the steps below.

ADJUSTING THE BEVEL ADJUSTMENT LEVER

(DW368, DW369)

NOTE: The following instructions also apply to adjusting the

DW367 and DW368 depth adjustment lever.

1. Using a small screwdriver, pry the lock ring off.

2. Remove the lever and rotate it in the desired direction about 1/8

of a revolution.

3. Reinstall the lock ring with the concave side against the lever.

English

ADJUSTING DEPTH ADJUSTMENT LEVER (DW369 ONLY)

1. Loosen the screw securing the depth adjustment lever.

2. Remove the depth adjustment lever and rotate it to the desired

location, about 1/8 of a revolution.

3. Tighten the lever screw.

Blades

A dull blade will cause inefficient cutting, overload on the saw

motor, excessive splintering and increase the possibility of kickback.

Change blades when it is no longer easy to push the saw through

the cut, when the motor is straining, or when excessive heat is built

up in the blade. It is a good practice to keep extra blades on hand

so that sharp blades are available for immediate use. Dull blades

can be sharpened in most areas; see SAWS-SHARPENING in the

yellow pages.

Hardened gum on the blade can be removed with kerosene,

turpentine, or oven cleaner. Anti-stick coated blades can be used

in applications where excessive build-up is encountered, such as

pressure treated and green lumber.

Règles de sécurité – Généralités

AVERTISSEMENT! Lire et comprendre toutes les

directives, car le non-respect des directives suivantes

peut entraîner un choc électrique, un incendie ou des

blessures graves.

CONSERVER CES DIRECTIVES

ZONE DE TRAVAIL

• Garder la zone de travail propre et bien éclairée; les établis

encombrés et les endroits sombres sont propices aux accidents.

• Ne pas utiliser les outils électriques dans une atmosphère

explosive, comme à proximité de liquides, de gaz ou de

poussières inflammables; le moteur peut créer des étincelles

et enflammer les vapeurs ou les poussières environnantes.

• Tenir les enfants, les visiteurs ou toute autre personne

éloignés lorsqu’on utilise un outil électrique; les distractions

peuvent faire perdre la maîtrise de ce dernier.

MESURES DE SÉCURITÉ - ÉLECTRICITÉ

• Les outils mis à la terre doivent être branchés dans une prise

bien installée et mise à la terre conformément à tous les

codes et règlements en vigueur. Ne jamais retirer la broche

de terre ni modifier la fiche. Ne pas utiliser d'adaptateur.

Vérifier auprès d'un électricien qualifié en cas de doute

quant à la mise à la terre de la prise. En cas de défaillance

électrique ou de bris de l'outil, la mise à la terre procure un

chemin de faible résistance au courant qui autrement traverserait

l'utilisateur. Cette protection ne s’applique qu’aux outils de

classe I (mis à la terre).

• Les outils à double isolation sont munis d’une fiche polarisée

(c’est-à-dire que l’une des lames est plus large que l’autre),

laquelle ne peut être raccordée qu’à une prise polarisée et

ce, dans un seul sens; on doit l’inverser si on est incapable

de l’enfoncer complètement. Si la fiche ne s’adapte toujours

pas, on doit demander à un électricien qualifié d’installer la

prise appropriée. On ne doit jamais modifier la fiche. La double

isolation

élimine le besoin d’installer un cordon d’alimentation

trifilaire et un système d’alimentation électrique pourvus d’une

mise à la terre; seuls les outils de classe II (à double isolation)

sont munis d’une telle protection. Les modèles DW367, DW368

et DW369 sont des outils à double isolation.

Français

• Éviter tout contact entre le corps et les éléments mis à la

terre, comme les tuyaux, les radiateurs, les cuisinières et les

réfrigérateurs, afin de réduire les risques de choc électrique.

• Ne pas utiliser l’outil électrique dans des endroits mouillés,

ni l’exposer à la pluie; l’infiltration d’eau à l’intérieur de l’outil

augmente les risques de choc électrique.

• Ne pas utiliser le cordon de manière abusive; on ne doit

pas transporter l’outil en le tenant par le cordon, ou utiliser

ce dernier pour le débrancher. On doit tenir le cordon éloigné

des sources de chaleur, de l’huile, des bords tranchants ou

des pièces mobiles. Remplacer immédiatement les cordons

endommagés, car ces derniers augmentent les risques de choc

électrique.

• Lorsqu’on utilise un outil électrique à l’extérieur, on ne doit

utiliser que des rallonges conçues pour cet usage, comme

celles de type « W-A » ou « W », afin de réduire les risques de

choc électrique. S’assurer que la rallonge est en mesure de porter

le courant nécessaire à l’outil. Une rallonge de calibre inférieur

entraînera une chute de tension se traduisant par une perte de

puissance et une surchauffe. Le tableau ci-dessous illustre les

calibres que l’on doit utiliser selon la longueur de la 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 porter du courant.

SÉCURITÉ PERSONNELLE

• Rester vigilant en tout temps et faire preuve de jugement

lorsqu’on utilise un outil électrique; ne pas utiliser l’outil

lorsqu’on est fatigué ou sous l’influence de drogues, d’alcool

ou de médicaments, car un moment d’inattention peut entraîner

des blessures graves.

• Porter des vêtements appropriés; ne pas porter de vêtements

amples, de gants ni de bijoux, et couvrir ou attacher les

cheveux longs, car ceux-ci peuvent rester coincés dans

les pièces mobiles. Se tenir éloigné des évents puisque ces

derniers pourraient camoufler des pièces mobiles.

• Éviter les démarrages accidentels; s’assurer que

l’interrupteur soit en position d’arrêt avant de brancher

l’outil. Ne pas transporter l’outil en laissant le doigt sur

l’interrupteur ni le brancher lorsque l’interrupteur est en position

de marche, car cela pourrait causer un accident.

• Retirer les clés de réglage avant de démarrer l’outil; une clé

laissée sur une pièce rotative peut entraîner des blessures.

• Ne pas trop étendre les bras; les pieds doivent rester

ancrés fermement au sol afin de maintenir son équilibre

en tout temps et de mieux maîtriser l’outil dans des situations

imprévues.

• Utiliser le matériel de sécurité approprié; toujours porter

des lunettes de protection. Porter un masque anti-poussières,

des chaussures antidérapantes, un casque de sécurité ou des

protecteurs auditifs lorsque la situation le requiert.

UTILISATION ET ENTRETIEN DE L’OUTIL

• Fixer et soutenir la pièce sur une plate-forme stable au

moyen d’une butée fixe ou de tout autre dispositif semblable;

la pièce est instable lorsqu’on la retient manuellement ou qu’on

l’appuie contre le corps, ce qui peut faire perdre la maîtrise de

l’outil.

Français

• Ne pas forcer l’outil ni l’utiliser pour des travaux autres que

ceux pour lesquels il a été conçu. Pour obtenir de meilleurs

résultats et prévenir les risques de blessure, laisser l’outil couper

à la vitesse pour laquelle il a été conçu.

• Ne pas utiliser l’outil lorsque l’interrupteur marche-arrêt ne

fonctionne pas; tout outil qui ne peut être commandé au moyen

de l’interrupteur est dangereux et doit être réparé.

• Débrancher l’outil avant d’effectuer un réglage, de changer

les accessoires ou de ranger l’outil; ces mesures de sécurité

préventives réduisent les risques de démarrage accidentel.

• Lorsqu’on n’utilise pas l’outil, le ranger hors de la portée

des enfants ou des personnes non qualifiées; les outils sont

dangereux entre les mains de personnes inexpérimentées.

• Bien entretenir l’outil et s’assurer qu’il soit toujours bien

propre et aiguisé; les outils bien entretenus et dont les bords

sont bien tranchants sont moins susceptibles de rester coincés

et sont plus faciles à maîtriser.

• Vérifier les pièces mobiles afin de s’assurer qu’elles soient

bien alignées et qu’elles ne restent pas coincées; vérifier

également les pièces afin de s’assurer qu’il n’y ait ni bris

ni aucune autre condition susceptible de nuire au bon

fonctionnement de l’outil; faire réparer l’outil si ce dernier

est endommagé avant de s’en servir à nouveau, car les

accidents sont souvent causés par des outils mal entretenus.

• N’utiliser que les accessoires recommandés par le fabricant

pour le modèle en question; un accessoire destiné à un outil

particulier peut devenir dangereux lorsqu’il est utilisé avec un

autre.

ENTRETIEN

• L’outil doit être entretenu par le personnel qualifié seulement;

toute maintenance effectuée par une personne non qualifiée

peut entraîner des risques de blessure.

• Lors de l’entretien, n’utiliser que des pièces de

rechange identiques et suivre les directives de la section

« Entretien » du présent manuel afin de prévenir les risques de

choc électrique ou de blessure.

Règles de sécurité additionnelles

concernant les scies circulaires

DANGER! Garder les mains éloignées des zones de coupe et

de la lame. Toujours tenir l’outil en plaçant une main sur la poignée

auxiliaire ou le carter du moteur; on protège ses mains en les utilisant

toutes les deux pour tenir l’outil.

AVERTISSEMENT : les lames ne s’arrêtent pas immédiatement

lorsque l’interrupteur est mis en position d’arrêt.

• Toujours se placer d’un côté ou de l’autre de la lame

en évitant de se tenir dans son trajet, car la scie pourrait

reculer brusquement par suite d’un REBOND. (Voir les sections

« Causes du rebond et mesures préventives » et « Effet de

rebond ».

• Ne pas mettre les mains sous la pièce car il n’y a aucune

protection contre la lame à cet endroit.

• Vérifier le protège-lame inférieur afin de s’assurer qu’il soit

bien fermé avant d’utiliser l’outil; ne pas faire fonctionner ce

dernier si le protège-lame ne se déplace pas librement ou

s’il ne se ferme pas instantanément. Ne jamais le bloquer

en position ouverte. Si on laisse tomber la scie, soulever le

protège-lame inférieur au moyen du levier d’escamotage et le

vérifier afin de s’assurer qu’il n’y ait aucun dommage, qu’il se

déplace librement et qu’il n’entre pas en contact avec la lame

ou toute autre pièce de l’outil, quels que soient l’angle et la

profondeur de coupe.

• S’assurer que le ressort du protège-lame inférieur soit en

bon état de fonctionnement; sinon, on doit lui faire subir

un entretien avant d’utiliser l’outil. Le protège-lame peut être
