Cordless Circular Saw Operator's Manual 7
CAUTION
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.
CHECK THE OPERATION AND CONDITION OF THE LOWER GUARD SPRINGS. IF THE
GUARD SPRINGS 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 THE 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 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.
WHEN RIPPING ALWAYS USE A RIP FENCE OR STRAIGHT EDGE GUIDE. This improves
the accuracy of the cut and reduces the chance for 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 eccentri-
cally, causing loss of control.
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.
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:
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.
