back toward the operator;
- If the blade becomes twisted or misalign 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 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 work-piece, 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 minimize 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 product 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.
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.
SAFETY INSTRUCTION FOR CIRCULAR SAW WITH INNER
PENDULUM GUARD
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 and make sure it
moves freely and does not touch the blade or any other parts, in all
angles and depths of cut.
Check the operation of the lower guard spring. If the guard and
the spring are not operating properly, they must be serviced
before use. Lower guard may operate sluggishly due to damaged
parts, gummy deposits, or a build-up of debris.
Lower guard should be retracted manually only for special cuts
such as "plunge cuts" and "compound cuts". Raise lower guard
by retracting handle and as soon as blade enters the material,
the lower guard must be released. For all other sawing, the lower
guard should operate automatically.
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
its path. Be aware of the time it takes for blade to stop after switch
is released.
