7o Do not reach underneath
the workpiece.
The guald cannot protect you from
the blade below the workpiece.

Always observe that the lower guard is covering the blade before placing
the 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.
9.
Always
use a rip fence
or straight
edge guide
when
ripping.
This improves
the accuracy
of the cut and reduces
the chance
of the blade binding,
I0
Always
use blades
with the correct
size and shape
(diamond
versus
round)
of arbor
holes.
Blades that do not match the mounting
hardware
of the saw will
run erratically,
causing
loss of control,
11, 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.
KICKBACK

r
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 reac-
tion drives the unit rapidly
back towards 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 ked
and jump back toward the
operator.

Incorrect Support
support is too far from cut line
Kickback is the result of
misuse and/or incorrect operating procedures or conditions and can be avoided
by taking proper precautions, as given below:
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.
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.
