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.

General Power Tool Safety Warnings

WARNING! Read all safety warnings and all instructions.

Failure to follow the warnings and instructions 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.

English

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.

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 situation.

5) BATTERY TOOL USE AND CARE

a) Recharge only with the charger specified by the

manufacturer. A charger that is suitable for one type of

battery pack may create a risk of fire when used with another

battery pack.

b) Use power tools only with specifically designated battery

packs. Use of any other battery packs may create a risk of

injury and fire.

English

c) When battery pack is not in use, keep it away from other

metal objects, like paper clips, coins, keys, nails, screws,

or other small metal objects, that can make a connection

from one terminal to another. Shorting the battery terminals

together may cause burns or a fire.

d) Under abusive conditions, liquid may be ejected from

the battery; avoid contact. If contact accidentally occurs,

flush with water. If liquid contacts eyes, additionally seek

medical help. Liquid ejected from the battery may cause

irritation or burns.

6) 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 All Saws

a) DANGER: Keep hands away from cutting area and

the 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.

b) Do not reach underneath the workpiece. The guard cannot

protect you from the blade below the workpiece.

c) Adjust the cutting depth to the thickness of the workpiece.

Less than a full tooth of the blade teeth should be visible below

the workpiece.

d) Never hold piece being cut in your hands or across

your leg. Secure the workpiece to a stable platform. It

is important to support the work properly to minimize body

exposure, blade binding, or loss of control.

e) Hold power tool by insulated gripping surfaces when

performing an operation where the cutting tool may

contact hidden wiring. Contact with a “live” wire will also

make exposed metal parts of the power tool “live” and shock

the operator.

f) When ripping always use a rip fence or straight edge

guide. This improves the accuracy of cut and reduces the

chance of blade binding.

g) Always use blades with correct size and shape (diamond

versus round) of arbor holes. Blades that do not match the

mounting hardware of the saw will run eccentrically, causing

loss of control.

h) Never use damaged or incorrect blade washers or bolt.

The blade washers and bolt were specially designed for your

saw, for optimum performance and safety of operation.

Further Safety Instructions for All Saws

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 the

operator.

Kickback is the result of saw misuse and/or incorrect operating

procedures or conditions and can be avoided by taking proper

precautions as given below:

a) Maintain a firm grip with both hands on the saw and

position your arms to resist kickback forces. Position

your body to either side of the blade, but not in line with

the blade. Kickback could cause the saw to jump backwards,

English

handle and make sure it moves freely and does not touch the

blade or any other part, in all angles and depths of cut.

b) Check the operation 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 build-

up of debris.

c) Lower guard should be retracted manually only for

special cuts such as “plunge cuts” and “compound cuts.”

Raise lower guard by retracting handle and as soon

as blade enters the material, the lower guard must be

released. For all other sawing, the lower guard should operate

automatically.

d) 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.

NOTE: Although the above information references wood, this saw is

only to be used to cut metal. Kickback can occur when cutting metal.

Additional Speciﬁ c Safety Instructions for

Circular Saws

WARNING: Do not use abrasive wheels or blades.

WARNING: Do not use water feed attachments.

CAUTION: Do not attempt to cut stainless steel, rebar,

hardened or heat-treated steel, cast iron, masonry or unknown

materials

• Use clamps or another practical way to secure and support

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

or against your body leaves it unstable and may lead to loss of

control.

but kickback forces can be controlled by the operator, if proper

precautions are taken.

b) 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.

c) When restarting a saw in the workpiece, center the

saw blade in the kerf and check that 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.

d) Support large panels to minimize the risk of blade

pinching and kickback. Large panels tend to sag under their

own weight. Supports must be placed under the panel on both

sides, near the line of cut and near the edge of the panel.

e) Do not use dull or damaged blades. Unsharpened or

improperly set blades produce narrow kerf causing excessive

friction, blade binding and kickback.

f) 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.

g) Use extra caution when making a “plunge cut” into

existing walls or other blind areas. The protruding blade

may cut objects that can cause kickback.

LOWER GUARD SAFETY INSTRUCTIONS

a) Check lower guard for proper closing before each use. Do

not operate the 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, lower

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

English

• 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).

• Air vents often cover moving parts and should be avoided.

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

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.

CAUTION: When not in use, place circular saw on a stable

surface, shoe side down, where it will not cause a tripping or

falling hazard. Some tools with large battery packs will stand upright

on the battery pack but may be easily knocked over.

FIG. 1

appropriate outlet before inserting

the battery pack.

2. Insert the battery pack (I)

into the charger, as shown in

Figure 1, making sure the pack

is fully seated in charger. The

red (charging) light will blink

continuously, indicating that the

charging process has started.

3. The completion of charge will

be indicated by the red light

remaining ON continuously. The pack is fully charged and may be

used at this time or left in the charger.

English

LEAVING THE BATTERY PACK IN THE CHARGER

The charger and battery pack can be left connected with the charge

indicator showing Pack Charged.

WEAK BATTERY PACKS: Weak batteries will continue to function

but should not be expected to perform as much work.

FAULTY BATTERY PACKS: This charger will not charge a faulty

battery pack. The charger will indicate faulty battery pack by refusing

to light or by displaying problem pack or charger.

NOTE: This could also mean a problem with a charger.

PROBLEM POWER LINE

Some chargers have a Problem Powerline indicator. When the charger

is used with some portable power sources such as generators or

sources that convert DC to AC, the charger may temporarily suspend

operation, flashing the red light with two fast blinks followed by a pause.

This indicates the power source is out of limits.

Important Charging Notes

1. Longest life and best performance can be obtained if the battery

pack is charged when the air temperature is between 65°F and

75 °F (18° – 24 °C). DO NOT charge the battery pack in an air

temperature below +40°F (+4.5°C), or above +105°F (+40.5°C).

This is important and will prevent serious damage to the battery

pack.

2. The charger and battery pack may become warm to the touch

while charging. This is a normal condition, and does not indicate

a problem. To facilitate the cooling of the battery pack after use,

avoid placing the charger or battery pack in a warm environment

such as in a metal shed or an uninsulated trailer.

3. A cold battery pack will charge at about half the rate of a warm

battery pack. The battery pack will charge at that slower rate

throughout the entire charging cycle and will not return to

maximum charge rate even if the battery pack warms.

Charge Indicators

This charger is designed to detect certain problems that can arise.

Problems are indicated by the red light flashing at a fast rate. If this

occurs, re-insert the battery pack into the charger. If the problem

persists, try a different battery pack to determine if the charger is

working properly. If the new pack charges correctly, then the original

pack is defective and should be returned to a service center or other

collection site for recycling. If the new battery pack elicits the same

trouble indication as the original, have the charger and the battery pack

tested at an authorized service center.

HOT/COLD DELAY

This charger has a hot/cold delay feature: when the charger detects a

battery that is hot, it automatically starts a delay, suspending charging

until the battery has cooled. After the battery has cooled, the charger

automatically switches to the pack charging mode. This feature

ensures maximum battery life. The red light flashes long, then short

while in the hot/cold delay mode.

English

4. If the battery pack does not charge properly:

a. Check operation of receptacle by plugging in a lamp or other

appliance;

b. Check to see if receptacle is connected to a light switch which

turns power off when you turn out the lights;

c. Move the charger and battery pack to a location where the

surrounding air temperature is approximately 65 °F – 75 °F

(18° – 24°C);

d. If charging problems persist, take the tool, battery pack and

charger to your local service center.

5. The battery pack should be recharged when it fails to produce

sufficient power on jobs which were easily done previously. DO

NOT CONTINUE to use under these conditions. Follow the

charging procedure. You may also charge a partially used pack

whenever you desire with no adverse effect on the battery pack.

6. Foreign materials of a conductive nature such as, but not limited

to, grinding dust, metal chips, steel wool, aluminum foil, or any

buildup of metallic particles should be kept away from charger

cavities. Always unplug the charger from the power supply when

there is no battery pack in the cavity. Unplug the charger before

attempting to clean.

7. Do not freeze or immerse the charger in water or any other liquid.

WARNING: Shock hazard. Don’t allow any liquid to get inside the

charger. Electric shock may result.

WARNING: Burn hazard. Do not submerge the battery pack in

any liquid or allow any liquid to enter the battery pack. Never attempt

to open the battery pack for any reason. If the plastic housing of the

battery pack breaks or cracks, return to a service center for recycling.

Storage Recommendations

1. The best storage place is one that is cool and dry, away from direct

sunlight and excess heat or cold.

2. For long storage, it is recommended to store a fully charged

battery pack in a cool dry place out of the charger for optimal

results.

NOTE: Battery packs should not be stored completely depleted of

charge. The battery pack will need to be recharged before use.

spindle with the large

flat surface facing out

toward the blade

(Fig.4, 5).

2. Retract the lower blade

guard (G) and place

blade on saw spindle

against the inner clamp

washer (O), 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.

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

only. Remove old blade.

3. Clean any metal chips/shavings 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.

Blades

WARNING: To minimize the risk of eye injury, always use eye

protection. Carbide is a hard but brittle material. Foreign objects in

the workpiece such as wire or nails can cause tips to crack or break.

Only operate saw when proper saw blade guard is in place. Mount

blade securely in proper rotation before using, and always use a

clean, sharp blade.

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 material 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

exists.

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. 9).

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 (Fig. 9).

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 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 a tooth as shown in Figure 8. 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 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. Overreaching 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.

4. 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.

5. 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 the

sections Further Safety Instructions for All Saws and Blades

for procedures and techniques that will minimize the occurrence of

kickback.

Depth Adjustment (Fig. 7, 8)

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

disconnect it from power source before installing and removing

accessories, before adjusting or when making repairs. An

accidental start-up can cause injury.

English

The metal-cutting saw is equipped with a pivoting shoe that allows the

operator to set the depth of cut. For the most efficient cutting action,

set the depth adjustment so that one tooth of the blade projects below

the material to be cut. This distance is from the tip of the tooth to the

bottom of the gullet in front of the tooth. This keeps blade friction at a

minimum, removes metal chips from the cut, results in cooler, faster

sawing and reduces the chance of kickback.

FIG. 7

FIG. 8

TO SET THE DEPTH OF CUT

1. Lay the piece of material you plan to cut along the blade as shown.

2. Note how much tooth projects beyond the material.

3. Loosen the depth adjustment lever (C) and move the shoe to

change the depth of cut.

4. Retighten the depth adjustment lever securely.

Workpiece Support (Fig. 9)

CUTTING SHEETS OF METAL

Figure 9 shows the correct and incorrect way to support a large sheet.

To avoid kickback, support material near the cut. Do not support it

away from the cut. If material is supported away from the cut, it will

bind the blade and cause kickback. When cutting thin strips, keep

the blade at least 1/2" (approximately 13 mm) from the edge of the

material. Thin strips may bind, causing kickback and increasing the

risk of personal injury.

FIG. 9

1/2"

(13 mm)

CUTTING RECTANGULAR METAL STOCK

Clamp the material you plan to cut to a workbench or other work

surface as shown above.

Cutting (Fig. 10, 11)

1. Hold the saw securely using both

FIG. 10

hands. Figure 10 shows

appropriate hand position. Keep

your body to one side of the line

along which you are cutting. This

will protect you from injury related

to kickback.

English

2. When cutting ends off of rectangular metal stock, place the widest

part of the shoe on the part of the material that is clamped to the

workbench or other support, not on the part of the material that

will fall when the cut is made.

3. Depress the trigger switch and allow the saw to reach full speed

before the blade contacts the material to be cut (Fig. 11).

FIG. 11

4. Push the saw forward at a speed that allows the blade to cut

without laboring.

5. As you finish a cut, release the trigger and allow the blade to stop

before lifting the saw from the work. As you lift the saw, the guard

will automatically close under the blade.

CORRECTING A CUT

Should your cut begin to leave the cutting line, don’t try to force it

back on. Forcing a correction can stall the saw and cause kickback.

Instead, release the switch and allow the blade to come to a complete

stop. Then, back the saw out of the cut. Restart the saw and re-enter

the cut, following the desired cutting line.

CAUTION: Do not cut through bolts with the metal-cutting saw.

Damage to the saw or personal injury could result.

Maximizing Blade Life

To extend blade life, follow these practices:

• Do not force the blade through the metal. The saw must cut at its

own pace and at a constant rate.

• Keep base of the saw firmly against metal you are cutting.

• If the metal you are cutting is vibrating or shaking, clamp the

material as close to the cut as possible and slow down the cutting

rate.

MAINTENANCE

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

disconnect it from power source before installing and removing

accessories, before adjusting or when making repairs. An

accidental start-up can cause injury.

Replacing Sight Window (Fig. 1)

WARNING: Do not operate the saw with a damaged or missing

sight or front window. If window is damaged or missing, have the

saw serviced at an authorized service center. If the saw is operated

without the window, metal chips could fly through the guard and

cause personal injury.

The sight window (J) must be replaced by an authorized D

EWALT

service center.

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.

CAUTION: Do not use any cleaning fluids on the sight window or

the front window to avoid clouding them and compromising the safe

operation of the saw. Use compressed air to remove accumulated

dust from the inside of the sight and front windows. Wear safety

glasses when performing this.
