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, re 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.
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
ammable 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 adaptor plugs with earthed (grounded) power tools. Unmodied plugs and matching
outlets will reduce the 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.
6
SAFETY INFORMATION
• 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 ground-fault circuit
interrupter (GFCI) protected supply. Use of a 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 inuence 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 nger on the switch or energizing power tools that have the
switch on invites accidents.
• 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 that these are connected and properly used. Use of these devices 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, 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.

SAFETY INFORMATION
Battery Tool Use and Care
• Recharge only with the charger specied by the manufacturer. A charger that is suitable
for one type of battery pack may create a risk of re when used with another battery pack.
• Use power tools only with specically designated battery packs. Use of any other
battery packs may create a risk of injury and re.
• 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 re.
• Under abusive conditions, liquid may be ejected from the battery; avoid contact. If
contact accidentally occurs, ush 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 qualied repair person using only identical
replacement parts. This will ensure that the safety of the power tool is maintained.
Specic Safety Warnings for Circular Saws
Safety Instructions for All Saws
DANGER
• Keep hands away from cutting area and the blade. Keep your second hand on the
auxiliary handle or motor housing. 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 to the thickness of the workpiece. Less than a full tooth of the
blade teeth should be visible below the workpiece.
• Never hold the 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, and loss of control.
• Hold the power tool by insulated gripping surfaces only, 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 could give the operator an
electric shock.
• When ripping, always use a rip fence or straight-edge guide. This improves the
accuracy of cut and reduces the chance of blade binding.
• Always use blades with arbor holes of the correct size and sharp (diamond versus
round).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 safe operation.

SAFETY INFORMATION
Cause 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 upper 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 rm 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 backward, but kickback forces can be
controlled by the operator if proper precautions are taken.
• 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 in the material. If the saw blade is binding, it may
walk up or kickback from the workpiece as the saw is restarted.
• Support larger panels to minimize the risk of blade pinching and kickback. Larger
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. Dull 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 a cut. If the blade adjustment shifts while cutting, it may cause binding and
kickback.
• Use extra caution when making a “plunge cut” into existing walls or other blind
areas. The protruding blade may contact hidden objects that can cause kickback.
Safety Instructions for Lower Blade Guard
• 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
bent. Raise the lower guard with the retracting handle and make sure that it moves freely
and does not touch the blade or any other part, in all angles and all depths of cut.
• Check the operation of the lower guard spring. If the guard and the spring are not
operating properly, they must be serviced before use. A 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 the lower guard with the retracting handle and,
as soon as blade enters the material, the 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 the saw down
on the bench or oor. 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.

Electric Brake
The circular saw is equipped with an electric brake.
When the trigger switch is released, the electric
brake engages automatically to quickly stop the rotation.
3. Blade Guard System
The lower blade guard (H) on the circular saw is
there for the operator’s protection and safety. Do
not alter it for any reason.
If the lower blade guard becomes damaged or if the
blade begins to run slowly or sluggishly, DO NOT
operate the saw until the damaged part has been
repaired or replaced. ALWAYS leave the guard in its
correct operating position when using the saw.
DANGER
• When sawing through a workpiece, the lower
blade guard does not cover the blade on the
underside of the workpiece. ALWAYS keep hands and body away from the cutting area.
Serious injury will result if any part of the body comes into contact with the moving blade.
WARNING
• To avoid possible serious injury, never use the saw when the lower blade guard is not
operating correctly. Check the lower blade guard for correct operation before each use. It
should move freely and instantly return to the closed position. If the saw is dropped, check
the lower blade guard and bumper for damage at all depth settings before using it.
If the lower blade guard does not snap closed at any time, take it to a qualied service
technician for repair.
