k) Never use the saw without the original
guard protection system. Do not lock the
moving guard in the open position. Ensure that
the guard operates freely without jamming.
l) Only use blades that comply with the
characteristics specified in this manual.
Before using accessories, always compare the
maximum allowed RPM of the accessory with
the RPM of the machine.

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:
1. 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.
2. 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
workpiece causing the blade to climb out of
the kerf and jump back towards the operator.
(3.3)
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) If the blades are binding, or when
interrupting a cut for any reason, release
the trigger and hold the saw motionless
in the material until the blades come to a
complete stop. Never attempt to remove
the saw from the work or pull the saw
backward while the blades are 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,
centre 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 minimise 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) Blade depth and bevel adjusting
locking levers must be tight and secure
before making a cut. If the blade adjustment
shifts while cutting it may cause binding and
kickback.
f) Do not use dull or damaged blades.
Unsharpened or improperly set blades
produce a narrow kerf causing excessive
friction, blade 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.
h) 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 (if equipped) and make sure it moves
freely and does not touch the blade or any
other part, in all angles and depths of cut.
