ENGLISH
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 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.
NOTE For circular saws with 185 mm or smaller
diameter blades, the words "with both hands" may
be omitted.
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 making a "plunge cut"
into existing walls or other blind areas. The
protruding blade may cut objects that can cause
kickback.
SAFETY INSTRUCTIONS FOR CIRCULAR SAW
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
6
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.
SAFETY INSTRUCTIONS FOR CIRCULAR SAW
a. Check guard for proper closing before each use.
Do not operate the saw if guarddoes not move
freely and enclose the blade instantly. Never
clamp or tie the guard with the blade exposed. If saw
is accidentally 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 and condition of the guard
return spring. If the guard and the spring are not
operating 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 guide 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 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.
