ELECTRICAL SAFETY
1. Do not abuse the cord. Never use the cord to carry the tool. Keep cord away
from heat, oil, sharp edges, or moving parts. Replace damaged cords
immediately. Damaged cords may create a fire.
2. 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.
3. Use battery operated tool only with specifically designated battery pack. Use
of any other batteries may create a risk of fire.
PERSONAL SAFETY
1. 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.
2. Dress properly. Do not wear loose clothing or jewelry. Contain long hair. Keep
your hair, clothing, and gloves away from moving parts. Loose clothes, jewelry,
or long hair can be caught in moving parts.
3. 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.
4. 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.
5. Do not overreach. Keep proper footing and balance at all times. Proper footing
and balance enable better control of the tool in unexpected situations.
6. 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
1. 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.
2. 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.
3. 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.
SKU 93808 For technical questions, please call 1-800-444-3353.
Page 3
English
4. Disconnect battery pack from tool or place the switch in the locked or off
position before making any adjustments, changing accessories, or storing
the tool. Such preventive safety measures reduce the risk of starting the tool
accidentally.
5. Store idle tools out of reach of children and other untrained persons. Tools are
dangerous in the hands of untrained users.
6. 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.
7. Maintain tools with care. Keep cutting tools sharp and clean. Properly maintained
tools with sharp cutting edge are less likely to bind and are easier to control.
8. 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.
9. 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
1. Tool service must be performed only by qualified repair personnel. Service or
maintenance performed by unqualified personnel may result in a risk of injury.
2. 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
1. 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. (See
KICKBACK)
Do not reach underneath the work. The guard can not protect you from the blade
below the work.
2. Check 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 accidentally 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.
3. 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.
4. 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.
5. 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.
6. 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.
7. Hold 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 tool “live” and shock the operator.
8. When ripping always use a rip fence or straight edge guide. This improves the
accuracy of cut and reduces the chance for blade binding.
9. 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.

10. Never use damaged or incorrect blade washers or bolts. The blade washers
and bolt were specially designed for your saw, for optimum performance and safety
of operation.
11. 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 tool misuse and/or incorrect operating procedures or
conditions and can be avoided by taking proper precautions as given below:
12. 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.
13. 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.
14. 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.
15. 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.
16. Do not use dull or damaged blade. Unsharpened or improperly set blades produce
narrow kerf causing excessive friction, blade binding, and KICKBACK.
17. Blade depth and bevel adjusting locking levers must be tight and secure before
making cut. If blade adjustment shifts while cutting, it will cause binding and
KICKBACK.
18. 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.
