GENERAL POWER TOOL SAFETY WARNINGS
WARNING Read all safety warnings, instructions, illustrations and specications
provided with this power tool. Failure to follow all instructions listed below 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 adapter plugs with earthed
(grounded) power tools. Unmodied 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 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 a 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 and clothing 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.
Do not let familiarity gained from frequent
use of tools allow you to become
complacent and ignore tool safety
principles. A careless action can cause severe
injury within a fraction of a second.

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 remove the battery pack,
if detachable, 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 and accessories.
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.
Keep handles and grasping surfaces dry,
clean and free from oil and grease. Slippery
handles and grasping surfaces do not allow
for safe handling and control of the tool in
unexpected situations.
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.
Do not use a battery pack or tool that is
damaged or modied. Damaged or modied
batteries may exhibit unpredictable behavior
resulting in re, explosion or risk of injury.
Do not expose a battery pack or tool to
re or excessive temperature. Exposure to
re or temperature above 265 °F may cause
explosion.
Follow all charging instructions and do
not charge the battery pack or tool outside
the temperature range specied in the
instructions. Charging improperly or at
temperatures outside the specied range may
damage the battery and increase the risk of re.
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.
Never service damaged battery packs.
Service of battery packs should only be
performed by the manufacturer or authorized
service providers.

SAFETY INSTRUCTIONS FOR CIRCULAR SAWS
Cutting procedures
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.
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 workpiece in your hands or
across your leg while cutting. 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 the 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
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 correct size and
shape (diamond versus round) of arbor
holes. Blades that do not match the mounting
hardware of the saw will run off-center, 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.
Kickback causes and related warnings
Kickback is a sudden reaction to a pinched,
jammed 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 jammed 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 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 backwards, 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 so that the
saw teeth are not engaged into the material.
If a saw blade binds, 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.
Blade depth and bevel adjusting locking
levers must be tight and secure before
making the cut. If blade adjustment shifts while
cutting, it may cause binding and kickback.
Use extra caution when sawing into existing
walls or other blind areas. The protruding
blade may cut objects that can cause kickback.

Lower guard function
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 it moves freely and does
not touch the blade or any other part, in all
angles and 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. Lower guard may operate
sluggishly due to damaged parts, gummy
deposits, or a build-up of debris.
The lower guard may be retracted manually
only for special cuts such as “plunge cuts”
and “compound cuts”. Raise the lower guard
by the 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 the saw
down on 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.
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.
Inspect the condition and quality of the wood
and remove all nails from lumber before
cutting. Wet lumber, green lumber or pressure
treated lumber require special attention during
cutting operation to prevent kickback.
Hold the saw rmly to prevent loss of
control. Figures in this manual illustrate typical
hand support of the saw.
This circular saw should not be mounted to
a table and converted to a table saw. Circular
saws are not designed or intended to be used
as table saws.
Never place your hand behind the saw
blade. Kickback could cause the saw to jump
backwards over your hand.
Do not use the saw with an excessive depth
of cut setting. Too much blade exposure
increases the likelihood of the blade twisting
in the kerf and increases the surface area of
the blade available for pinching that leads to
kickback
Do not run the tool while carrying it at your
side. Lower guard may be opened by a
contact with your clothing. Accidental contact
with the spinning saw blade could result in
serious personal injury.
Periodically remove the blade, clean the
upper, lower guards with kerosene and wipe
it dry, or blow it clean with compressed air.
Preventive maintenance and properly operating
guard will reduce the probability of an accident.
ADDITIONAL SAFETY WARNINGS
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, cement, and
other masonry products.
– Arsenic and chromium from chemically-treated
lumber.
• Your risk from these exposures varies,
depending upon how often you do this type
of work. To reduce your exposure to these
chemicals:
– Work in a well-ventilated area.
– Work with approved safety equipment, such as
dust masks that are specially designed to lter
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 or eyes or
to lie on the skin may promote absorption of
harmful chemicals.
