g ) Always use blades with correct size and shape
(diamond versus round) of arbor holes. Blades that
do not match the mounting hardware of the saw will
run off‑center, causing loss of control.
h ) Never use damaged or incorrect blade washers
or bolt. The blade washers and bolt were specially
designed for your saw, for optimum performance and
safety of operation.
Further Safety Instructions for All Saws
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 saw misuse and/or incorrect operating
procedures or conditions and can be avoided by taking proper
precautions as given below:
a ) Maintain a firm grip with both hands on the saw
and position your arms to resist kickback forces.
Position your body to either side of the blade,
but not in line with the blade. Kickback could cause
the saw to jump backwards, but kickback forces can
be controlled by the operator, if proper precautions
are taken.
b ) 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.
c ) 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.
d ) 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.
e ) Do not use dull or damaged blades. Unsharpened
or improperly set blades produce narrow kerf causing
excessive friction, blade binding and kickback.
f ) Blade depth and bevel adjusting locking levers
must be tight and secure before making cut. If
blade adjustment shifts while cutting, it may cause
binding and kickback.
g ) Use extra caution when making a "plunge
cut" into existing walls or other blind areas.
The protruding blade may cut objects that can
cause kickback.
Lower Guard Function Safety
Instructions
a ) Check lower guard for proper closing before each
use. Do not operate the 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.
b ) Check the operation 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 build‑up of debris.
c ) Lower guard should be retracted manually
only for special cuts such as "plunge cuts" and
"compound cuts." Raise lower guard by retracting
handle and as soon as blade enters the material,
the lower guard must be released. For all other
sawing, the lower guard should operate automatically.
d ) 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.
Additional Safety Information
WARNING: Never modify the power tool or any part of
it. Damage or personal injury could result.
WARNING: ALWAYS use safety glasses. Everyday
eyeglasses are NOT safety glasses. Also use face or
dust mask if cutting operation is dusty. ALWAYS WEAR
CERTIFIED SAFETY EQUIPMENT:
•
ANSI Z87.1 eye protection (CAN/CSA Z94.3),
•
ANSI S12.6 (S3.19) hearing protection,
•
NIOSH/OSHA/MSHA respiratory protection.
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
