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.
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.
3
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,
4
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
5
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.

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.

with the notch on the front of the shoe and centering it using the
modified V-shaped kerf indicator allows the operator to keep the
blade in line with the cutting line. If the cutting line is visible through
the narrowest part of the kerf indicator, the blade will pass directly over
the cutting line.
Worklight
The saw is equipped with a worklight that is activated when the trigger
switch is depressed. The light will automatically turn off 20 seconds
after the trigger switch is released. If the trigger switch remains
depressed, the worklight will remain on.
NOTE: The worklight is for lighting the immediate work surface and is
not intended to be used as a flashlight.

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.
16
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
C
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.
17
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.
