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 work-
piece 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. Un-
sharpened or improperly set blades pro-
duce narrow kerf causing excessive fric-
tion, 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 circular saws
with outer pendulum guard, circular
saws with inner pendulum guard , cir-
cular saws with tow guard
а) 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 saw-
ing, the lower guard should operate auto-
matically.
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 instructions for all
saws with riving knife
а) Use the appropriate saw blade for the riv-
ing knife. For the riving knife to function,
the body of the blade must be thinner than
the riving knife and the cutting width of the
blade must be wider than the thickness of
the riving knife.
b) Adjust the riving knife as described in
this instruction manual. Incorrect spacing,
positioning and alignment can make the riv-
ing knife ineffective in preventing kickback.
c) Always use the riving knife except when
plunge cutting. Riving knife must be re-
placed after plunge cutting. Riving knife
causes interference during plunge cutting
and can create kickback
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.
Wear hearing protection during continu-
ous operation. Exposure to noise can cause
hearing loss.
During operation provide eye protection
to prevent eyes from exposure to flying
particles. Wear goggles.
Take protective measures against inha-
lation of dust. Some materials can contain
toxic ingredients. Wear a dust mask and
work with dust/chip extraction when connect-
able.
▪ Do not process materials containing asbes-
tos. Asbestos is considered carcinogenic.
▪ Use of protective gloves is recommended.
