ELECTRICAL SAFETY
OVERHEATING AND FIRE HAZARD
WARNING: To avoid electrical hazards, fire hazards or damage to the
tool, use proper circuit protection.
This tool is wired at the factory for 120V AC operation. It must be connected
to a 120V AC, 15 AMP circuit that is protected by a time-delayed fuse or
circuit breaker. To avoid shock or fire, replace power cord immediately if it
is worn, cut or damaged in any way.
GENERAL SAFETY WARNINGS
WEAR A DUST MASK THAT IS DESIGNED TO BE USED WHEN
OPERATING A POWER TOOL IN A DUSTY ENVIRONMENT.
WARNING: Dust that is created by power sanding, sawing, grinding,
drilling, and other construction activities may contain chemicals that are
known to cause cancer, birth defects, or other genetic abnormalities. These
chemicals include:
Lead from lead-based paints
Crystalline silica from bricks, cement, and other masonry products
Arsenic and chromium from chemically treated lumber
The level of risk from exposure to these chemicals varies, according to how
often this type of work is performed. In order to reduce exposure to these
chemicals, work in a well-ventilated area, and use approved safety
equipment, such as a dust mask that is specifically designed to filter out
microscopic particles.
!
WARNING: Ventilation openings in batteries and chargers must always be
open to allow cooling air to circulate freely. Air vents that are blocked,
restricted or covered may result in the battery or charger overheating.
Overheating may lead to damage to the tool or cause a fire, resulting in
possible serious injury.
!

5
WARNING: Read all safety warnings
and 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.
Work area safety
Keep work area clean and well lit.
Cluttered or 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 children and bystanders away
while operating a power tool.
Distractions can cause you to lose control.
Electrical safety
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.
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.
Do not 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 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.
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.
If operating a power tool in a damp
location is unavoidable, use a residual
current device (RCD) protected supply.
Use of a ground fault circuit interrupter
(GFCI) reduces the risk of electric shock.
Personal safety
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.
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.
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.
POWER TOOL SAFETY
!

PERSONAL SAFETY –cont’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.
Do not overreach. Keep proper footing
and balance at all times. This enables
better control of the power tool in
unexpected situations.
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.
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.
Power tool use and care
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.
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.
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.
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.
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.
Keep cutting tools sharp and clean.
Properly maintained cutting tools with
sharp cutting edges are less likely to bind
and are easier to control.
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.
Hold power tools 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 make exposed metal
parts of the tool “live“and shock the
operator.
POWER TOOL SAFETY
SAVE THESE INSTRUCTIONS FOR REFERENCE

Battery tool use and care
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.
Use power tools only with specifically
designated battery packs. Use of any
other battery packs may create a risk of
injury and fire.
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.
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.
Service
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.
POWER TOOL SAFETY
SAVE THESE INSTRUCTIONS FOR REFERENCE

WARNING: Know your circular
saw. Do not plug the charger into the
power source or install a battery in the
tool until you have read and understand
this Instruction Manual. Learn the tool’s
applications and limitations, as well as
the specific potential hazards related to
this tool. Following this rule will reduce the
risk of electric shock, fire, or serious injury.
Always wear eye protection.
Any power tool can throw
foreign objects into your eyes
and cause permanent eye
damage. ALWAYS wear safety goggles
(not glasses) that comply with ANSI safety
standard Z87.1. Everyday glasses have
only impact resistant lenses. They ARE
NOT safety glasses.
WARNING: Glasses or goggles
not in compliance with ANSI Z87.1
could cause serious injury when they
break.
Always keep hands out of the path of the
saw blade. Avoid awkward hand positions
where a sudden slip could cause your
hand to move into the path of the saw
blade.
DANGER: Keep hands away from
cutting area and the blade. Keep your
second hand on the tool. If both hands
are holding the saw, they cannot be cut by
the blade.
Do not reach underneath the workpiece.
The guard cannot protect you from the
blade below the workpiece.
Adjust the cutting depth according to
the thickness of the workpiece. Less
than a full tooth of the blade teeth should
be visible below the workpiece or
approximately 3/8" (10 mm).
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.
Hold power 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 power tool “live” and
shock the operator.
When ripping always use a straight
edge guide. This improves the accuracy of
cut and reduces the chance of the blade
binding.
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.
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.

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:
Maintain a firm grip with both hands on
the saw and position your arms to
resist kickback forces. Position your
body to the left or right side of the
blade, but not in line with the blade.
Kickback could cause the saw to jump
backwards, but kickback forces can be
controlled by the operator, if proper
precautions are taken.
When the 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 saw teeth are not engaged
into the material. If the saw blades are
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. Supports 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 blades.
Unsharpened or improperly set blades
produce narrow kerf causing excessive
friction, blade binding and kickback.
ADDITIONAL SPECIFIC SAFETY RULES
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.
Check the lower guard for proper
closing before each use. Do not operate
the saw if the lower guard does not
move freely and close instantly. Never
clamp or tie the lower guard into the
open position. If the saw is accidentally
dropped, the lower guard may be
damaged. Raise the lower guard with the
retracting handle and make sure it moves
freely and does not touch the blade or any
other part in all depths of cuts.
SPECIFIC SAFETY RULES

10
ADDITIONAL SPECIFIC SAFETY RULES –
cont’d
Check the operation of the lower guard
spring. If the guard and the spring are
not operating properly, they must be
serviced before use. The lower guard
may operate sluggishly due to damaged
parts, gummy deposits, or a build-up of
debris.
The 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 the blade enters the
material, the lower guard must be
released. For all other sawing, the lower
guard should operate automatically.
Always observe that the lower guard is
covering the blade before placing saw
down on the bench or on the 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 the switch is
released.
Never operate the saw while it is being
carried to another location. The blade
guard may be open and potentially cause
serious injury.
If the switch fails to turn the saw ON or
OFF properly, stop using it immediately
and have the saw switch repaired.
Always allow the saw to reach full speed
before beginning the cut.
Never use the side of the blade for cutting.
When making horizontal cuts, make sure
the weight of the tool is not forcing the side
of the blade to do the cutting. This will
reduce the risk of kickback.
Make sure there are no nails or foreign
objects in the area of the workpiece to be
cut.
Never lay workpiece on hard surfaces
like concrete, stone, etc. The protruding
blade may cause tool to jump.
DANGER: To avoid injury from
accidental starting, always remove the
plug from the power source before
making any adjustments and before
installing or removing a saw blade.
When replacing the blade, make sure
the replacement blade is 5½"
(14 cm) in diameter and is rated for at
least 3,800 RPM. Installing an incorrect
blade will result in possible injury and poor
cutting action.
After changing a blade or making
adjustments, make sure the blade
clamp screw is securely tightened.
Loose blades and adjustment devices will
be violently thrown.
Never touch the blade during or
immediately after use. After use the
blade is too hot to be safely touched with
bare hands.
DANGER: Never use the laser in the
presence of small children. Small children
may stare directly into the laser light beam
and cause serious eye injury.
DANGER: The laser light beam that
is projected from the front of the laser level
can be dangerous to eyesight. Never allow
anyone to stare directly into the light.
Staring directly into the light beam may
result in serious eye damage.
DANGER: Always remove the
battery when changing the blade.
