— kickback is a sudden reaction to a pinched,
jammed 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 jammed 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 so that
the saw teeth are not engaged into the
material.
If a saw blade binds, 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 the 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 CIRCULAR SAW WITH
INNER PENDULUM GUARD
Lower guard function
a) Check the lower guard for proper closing
before each use. Do not operate the saw
if the lower guard does not move freely
and close instantly. Never clamp or tie
the lower guard into the open position.
If the saw is accidentally dropped, the 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) The lower guard may be retracted
manually only for special cuts such as
“plunge cuts” and “compound cuts.”
Raise the lower guard by retracting handle
and as soon as the 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 the 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.
3. Use only blade diameter(s) in accordance with
the markings.
4. Identify the correct saw blade to be used for
the material to be cut.
5. Use only saw blades that are marked with a
speed equal or higher than the speed marked
on the tool.
