h) 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.
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;
-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 of the wood causing the blade
to climb out of the kerf and jump back toward the
operator.
Kickback is 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) 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.
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) Do not use dull or damaged blades.
Unsharpened 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) Take particular care when making a "plunge
cut" in a hidden area, e.g. an existing wall. The
saw blade can lock when sawing in concealed
objects and cause a back-kick.
---------------------------------------------------
a) 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 posi-
tion. If saw is accidentally dropped, lower guard
may be bent. Raise the lower guard with the
retracting handle and make sure it 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 lower guard
spring. If the guard and the spring are not oper-
ating properly, they must be serviced before use.
Lower guard may operate sluggishly due to
damaged parts, gummy deposits, or a build-up of
debris.
c) Open the bottom protective cover by hand
only when making special cuts, such as plunge
cuts and angle cuts. Open the bottom protective
cover with the pull-back lever and release it as
soon as the saw blade has penetrated the work-
piece. For all other sawing tasks, the bottom
protective cover must operate automatically.
d) Always observe that the lower guard is
covering the blade before placing saw down on
bench or floor. An unprotected, coasting blade will
cause the saw to walk backwards, cutting whatever
is in path. Be aware of the time it takes for the blade
to stop after switch is released.
Riving knife:
a) Use the appropriate riving knife for the blade
being used. For the riving knife to work, it must be
thicker than the body of the blade but thinner than
the tooth set of the blade.
b) Adjust the riving knife as described in this
instruction manual. Incorrect spacing, positioning
and alignment can make the riving knife ineffective
in preventing kickback.
c) Always use the riving knife.
d) For the riving knife to work, it must be
engaged in the workpiece. The riving knife is
ineffective in preventing kickback during short cuts.
e) Do not operate the saw if riving knife is bent.
Even a light interference can slow the closing rate of
a guard.
Pull the plug out of the plug socket before any
adjustments or servicing are performed.
Keep hands away from the rotating tool! Remove
chips and similar material only with the machine at
standstill.
