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

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.
