Tool Use and Care
Use clamps or other practical way to secure and support the workpiece to a
stable platform. Holdingthe work by handor againstyour body is unstableand
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 storingthe
tool. Such preventive safety measures reduce the risk
of starting the tool
accidenta
I I y.
Store idle tools out of 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 terminaltoanother. Shortingthebatteryterminals
together may cause sparks, burns, or a fire.
Maintaintools with care. Keepcuttingtools sharpandclean. Properly maintained
tools
with sharp cutting edge are less likely to bind and are easier to control.
Check for misalignment or bindingof movingparts, breakageof parts, andany
other conditionthat may affectthetool’s operation. Ifdamaged, havethe 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 suitablefor one tool maycreatea risk of injury
when used on another tool.
Service
Tool service must be performed only by qualified repair personnel. Service or
maintenance performed
by unqualified personnel may result in a risk of injury.
When servicinga 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 cuttingarea 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
withthe saw blade. KICKBACK could cause the saw tojump backwards. (See
"Causes and Operator Prevention of Kickback")
Do not reach underneath the work while blade is rotating. The guard can
not protect you from the blade below the work. Don't attempttoremove cut
material when blade is moving.
CAUTION: Blades coast after turn
off.
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 intothe open position.
If saw is accidentally dropped, lower
guard may be bent. Raisethe lower guard
with the Retracting Handleand make
sure
it movesfreely and does nottouch 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
andthe spring are not operating properly, they must be serviced beforeuse.
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, lowerguardmustbe 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 acrossyour leg. It is important
to support the work properly to minimize body exposure, blade binding, or
loss of control.
7. Holdtool by insulatedgripping surfaces when performing an operation where
the cutting tool may contact hidden wiring or its own cord. 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 (diamondvs. round) arbor
holes. Blades that do not matchthe mounting hardware
of the saw will run
eccentrically, causing
loss of control.
IO. Never use damaged or incorrect blade washers or bolts. The blade washers
and bolt were specially designed for your saw, for optimumperformance and
safety or 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 bladeis pinched or bound tightly by thekerf 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 operator.
Kickback is the result of tool misuse and/or incorrect operating procedures
or conditions and can be avoidedby takingproper precautions as given below.
Maintain a firm grip with bothhands onthe saw and positionyour bodyand
arm to allow 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 holdthe saw motionless
in the material until the blade comes
toa complete stop. Never attempt to removethe saw from the work or pull
the saw backward while the blade is
in motion or KICKBACK may occur.
Investigateandtake corrective actionstoeliminate the cause of blade binding.
When restarting a saw
in the workpiece, center the saw blade in the kerf
and check that saw 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 panelstominimize 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.
To avoid kickback do support board
or panel near the cut. Don’t support board or panel away
from the cut.
Fig. 1 Fig.

Do not use dull or damaged blade. Unsharpened or improperly set blades
produce narrow kerf causing excessive friction, blade bindingand KICKBACK.
Blade depth and bevel adjusting lockinglevers must be tight and secure before
making cut. If blade adjustment shifts while cutting,
it may cause binding and
KICKBACK.
Use extra caution when makinga "Pocket Cut" into existing walls or other
blindareas. The protruding blade may cut objects that can cause KICKBACK.
NEVER place your hand or fingers
behind the saw. If kickback occurs,
the saw could easily jump backwards
over your hand, possibly causing
severe injury.
Fig. ,
12. Adjustments. Before cuttingbesure depth and bevel adjustments are tight.
13. Avoid Cutting Nails. Inspect for and remove all nails from lumber before
cutting.
14. When operating the saw, keep the
cord away from the cuttingarea and
position
it so that it willnotbecaught
on the workpiece during the cutting
operation.
Operate with proper hand support,
proper workpiece support, and
supply cord routing away from the
work area.
