injury, or may cause machine damage.
NOTE emphasizes essential information.
SAFETY
GENERAL SAFETY RULES – FOR ALL BATTERY OPERATED TOOLS
WARNING:
Read and understand all instructions.
Failure to follow all instructions listed below, may result in electric shock, fire and/or serious personal injury.
SAVE THESE INSTRUCTIONS
1. Work Area
(1) Keep your work area clean and well lit.
Cluttered benches and dark areas invite
accidents.
(2) 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 of
fumes.
(3) Keep bystanders, children, and visitors away
while operating a power tool. Distractions
can cause you to lose control.
2. Electrical Safety
(1) 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.
(2) Use battery operated tool only with
specifically designed battery pack. Use of any
other batteries may create a risk of fire.
3. 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
off position before inserting battery. 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 enables better control of the tool in
unexpected situations.
(6) Use safety equipment. Always wear eye
protection. Dust mask, non-skid safety shoes,
hard hat, or hearing protection must be used
for appropriate conditions.
3
English
4. 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. Any tool that cannot be controlled with
the switch is dangerous and must be repaired.
(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 tools. 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 edges 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 tools 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.
5. Service
(1) Tool service must be performed only by
qualified repair personnel. Service or
maintenance performed by unqualified
personnel could 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 Instruction may create a risk of
electric shock or injury.

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 and cement and other
masonry products, and
●
Arsenic and chromium from chemically-treated
lumber.
Your risk from these exposures varies, depending
on how often you do this type of work. To reduce
your exposure to these chemicals: work in a well
ventilated area, and work with approved safety
equipment, such as those dust masks that are
specially designed to filter out microscopic particles.
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 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.
English
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:
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 as shown in Fig. 1.
To minimize the risk of blade pinching and
kickback. When cutting operation requires the
resting of the saw on the work piece, the saw shall
be rested on the larger portion and the smaller
piece cut off.
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.
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.
19. Hold 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.
20. Never touch moving parts.
Never place your hands, fingers or other body parts
near the tool’s moving parts.
To avoid kickback, do support board
or panel near the cut.

Don't support board or panel
away from the cut.

features in place and in proper working order. If
maintenance or servicing requires the removal of
a guard or safety feature, be sure to replace the
guard or safety feature before resuming operation
of the tool.
22. Use right tool.
Don’t force small tool or attachment to do the job
of a heavy-duty tool.
Don’t use tool for purpose not intended —for
example— don’t use circular saw for cutting tree
limbs or logs.
23. Never use a power tool for applications other than
those specified.
Never use a power tool for applications other than
those specified in the Instruction Manual.
