h) Never use damaged or incorrect
blade washers or bolt. The blade
washers and bolt were designed for
your saw, for optimum performance
and safety or operation.
Cause and operator prevention of
kickback:
- kickback is sudden reaction to a
pinched, bound or misaligned saw
blade, causing and 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 if the wood causing
the blade to climb out the kerf and
jump back toward the operator.
- 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.

- Kickback is the result of saw
misuse and/or incorrect operating
procedures
or
can be avoided by tacking 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 of kickback
may occur. Investigate and take
corrective actions to eliminate the
cause of blade biding.
c) When restarting a saw in the
workplace, 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 retarded.
