GENERAL SAFETY RULES
WARNING:
Read and follow all instructions. Failure to follow all
instructions listed below, may result in electric shock, fire
and/or serious personal injury.
SAVE THESE INSTRUCTIONS
Work Area
■ Keep your work area clean and well lit. Cluttered
benches and dark areas invite accident.
■ 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 bystanders, children, and visitors away while
operating a power tool. Distractions can cause you to
lose control.
Electrical Safety
■ Do not abuse the cord. Never use the cord to carry
the charger. Keep cord away from heat, oil, sharp
edges, or moving parts. Replace damaged cords
immediately. Damaged cords may create a fire.
■ A battery operated tool with integral batteries or a
separate battery pack must be recharged only with
the specified charger for the battery. A charger that
may be suitable for one type of battery may create a risk
of fire when used with another battery. Use battery only
with charger listed.

130256001 or 130224007
■ Use battery operated tool only with specifically designated battery pack. Use of any other batteries may
create a risk of fire. Use only with battery pack listed.
Personal Safety
■ Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use
tool while tired or under the influence of drugs, alcohol, or medication. A moment of inattention while
operating power tools may result in serious personal injury.
■ Dress properly. Do not wear loose clothing or jewelry. Contain long hair. Keep your hair, clothing, and
gloves away from moving parts. Loose clothes, jew-
elry, or long hair can be caught in moving parts.
■ Avoid accidental starting. Be sure switch is in the
locked or off position before inserting battery pack.
Carrying tools with your finger on the switch or inserting
the battery pack into a tool with the switch on invites
accidents.
■ Remove adjusting keys or wrenches before turning
the tool on. A wrench or a key that is left attached to a
rotating part of the tool may result in personal injury.
■ Do not overreach. Keep proper footing and balance
at all times. Proper footing and balance enable better
control of the tool in unexpected situations.
■ Use safety equipment. Always wear eye protection.
Dust mask, nonskid safety shoes, hard hat, or hearing
protection must be used for appropriate conditions.
Tool Use and Care
■ 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.
■ Do not force tool. Use the correct tool for your application. The correct tool will do the job better and safer
at the rate for which it is designed.
■ Do not use tool if switch does not turn it on or off. A
tool that cannot be controlled with the switch is dangerous and must be repaired.
■ Disconnect battery pack from tool or place the switch
in the locked or off position before making any adjustments, changing accessories, or storing tool.
Such preventive safety measures reduce the risk of starting the tool accidentally.
■ Store idle tools out of the reach of children and other
untrained persons. Tools are dangerous in the hands
of untrained users.
■ 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
sparks, burns, or a fire.
■ Maintain tools with care. Keep cutting tools sharp
and clean. Properly maintained tools with sharp cutting
edges are less likely to bind and are easier to control.
■ Check for misalignment or binding of moving parts,
breakage of parts, and any other condition that may
affect the tool’s operation. If damaged, have the tool
serviced before using. Many accidents are caused by
poorly maintained tools.
■ Use only accessories that are recommended by the
manufacturer for your model. Accessories that may
be suitable for one tool, may create a risk of injury when
used on another tool.
Service
■ Tool service must be performed by qualified repair
personnel. Service or maintenance performed by un-
qualified personnel may result in a risk of injury.
■ When servicing a tool, use only identical replacement parts. Follow instructions in the Maintenance
section of this manual. Use of unauthorized parts or
failure to follow Maintenance Instructions may create a
risk of shock or injury.

SPECIFIC SAFETY RULES
Hold tool by insulated gripping surfaces when performing an operation where the cutting tool may contact hidden
wiring. Contact with a "live" wire will make exposed metal parts of the tool "live" and shock the operator.
Additional Rules For Safe Operation
■ Know your power tool. Read operator’s manual carefully. Learn its 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.
■ Make sure your extension cord is in good condition.
When using an extension cord, be sure to use one
heavy enough to carry the current your product will
draw. A wire gage size (A.W.G.) of at least 16 is recommended for an extension cord 100 feet or less in
length. A cord exceeding 100 feet is not recommended. If in doubt, use the next heavier gage. The
smaller the gage number, the heavier the cord. An
undersized cord will cause a drop in line voltage resulting in loss of power and overheating.
Important Rules For Battery Tools
■ Battery tools do not have to be plugged into an electrical outlet; therefore, they are always in operating
condition. Be aware of possible hazards when not
using your battery tool or when changing accessories.
■ Do not place battery tools or their batteries near fire
or heat. This will reduce the risk of explosion and pos-
sible injury.
WARNING:
Batteries vent hydrogen gas and can explode in the
presence of a source of ignition, such as a pilot light. To
reduce the risk of serious personal injury, never use any
cordless product in the presence of open flame. An
exploded battery can propel debris and chemicals. If
exposed, flush with water immediately.
■ Do not charge battery tool in a damp or wet location. Following this rule will reduce the risk of electric
shock, fire, or serious personal injury.
■ Your battery tool should be charged in a location
where the temperature is more than 50°F but less
than 100°F. Following this rule will reduce the risk of
electric shock, fire, or serious personal injury.
■ Under extreme usage or temperature conditions,
battery leakage may occur. If liquid comes in contact with your skin, wash immediately with soap and
water, then neutralize with lemon juice or vinegar. If
liquid gets into your eyes, flush them with clean water
for at least 10 minutes, then seek immediate medical attention. Following this rule will reduce the risk of
serious personal injury.
Additional Specific Safety Rules
■ DANGER! Keep hands away from cutting area and
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.
■ Keep your body positioned to either side of the saw
blade, but not in line with the saw blade. KICKBACK
could cause the saw to jump backwards.
■ Do not reach underneath the work. The guard cannot
protect you from the blade below the work.
■ Check the lower guard for proper closing before each
use. Do not operate 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 acciden-
tally dropped, 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 and condition 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 buildup of debris.
■ Lower guard should be retracted manually only for
special cuts such as “Pocket Cuts” and “Compound
Cuts”. Raise lower guard by Retracting Handle. As
soon as blade enters the material, 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 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.
■ NEVER hold piece being cut in your hands or across
your leg. It is important to support the work properly to
minimize body exposure, blade binding, or loss of control.
■ Hold tool by insulating 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 tool “live” and shock
the operator.
■ When ripping always use a rip fence for a straight
edge guide. This improves the accuracy of cut and re-
duces the chance of blade binding.
■ Always use blades with correct size and shape (diamond vs. round) arbor holes. Blades that do not match
the mounting hardware of the saw will run eccentrically,
causing loss of control.

SPECIFIC SAFETY RULES
Additional Specific Safety Rules Continued
■ Never use damaged or incorrect blade washers or
bolts. The blade washers and bolt were specially de-
signed 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 a result of tool misuse and/or incorrect operating procedures or conditions and can be avoided by
taking proper precautions as given below:
■ Maintain a firm grip on the saw and position your
body and arm in a way that allows you to resist KICKBACK forces. 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 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.
■ 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 blade. 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 cut. If blade ad-
justment shifts while cutting, it will cause binding and
KICKBACK.
■ Use extra caution when making a “Pocket Cut” into
existing walls or other blind areas. The protruding
blade may cut objects that can cause KICKBACK.
