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 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 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) Use extra caution when sawing into
existing walls or other blind areas.
The protruding blade may cut objects that
can cause kickback.
SAFETY INSTRUCTIONS FOR SAWS
WITH INNER PENDULUM GUARD
LOWER GUARD FUNCTION
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 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 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 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.
c) Lower guard may 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.
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 its path. Be aware of the time it
takes for the blade to stop after switch is
released.
ADDITIONAL SAFETY RULES FOR YOUR
CIRCULAR SAW
1. Only use saw blades recommended in the
specification.
2. Do not use any abrasive wheels.
