by the kerf closing down, the blade stalls
and the motor reaction drives the unit rap-
idly 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 precau-
tions 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 inter-
rupting 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,
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 work-
piece 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) Do not use dull or damaged blades. Un-
sharpened 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 sawing into
existing walls or other blind areas. The
protruding blade may cut objects that can
cause kickback.
GUARD FUNCTION
a) Check guard for proper closing before
each use. Do not operate the saw if
guard does not move freely and close in-
stantly. Never clamp or tie the guard so
that the blade is exposed. If saw is acci-
dentally dropped, guard may be bent. Check
to make sure that guard 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 guard spring.
If the guard and the spring are not op-
erating properly, they must be serviced
before use. Guard may operate sluggishly
due to damaged parts, gummy deposits, or
a build-up of debris.
c) Assure that the base plate of the saw will
not shift while performing the "plunge
cut" when the blade bevel setting is not
at 90°. Blade shifting sideways will cause
binding and likely kick back.
d) Always observe that the guard is cover-
ing the blade before placing saw down
on bench or floor. An unprotected, coast-
ing blade will cause the saw to walk back-
wards, cutting whatever is in its path. Be
aware of the time it takes for the blade to
stop after switch is released.
RIVING KNIFE FUNCTION
a) Use the appropriate saw blade for the
riving knife. For the riving knife to func-
tion, the body of the blade must be thinner
than the riving knife and the cutting width of
the blade must be wider than the thickness
of the riving knife.
b) Adjust the riving knife as described in
this instruction manual. Incorrect spac-
ing, positioning and alignment can make
the riving knife ineffective in preventing
