• If the saw blade is twisted in the saw
cut or incorrectly aligned, the teeth of
the rear edge of the saw blade can
jam in the wood surface, causing the
sawbladetomoveoutofthesawing
gap and the saw to recoil in the
direction of the operator.
Spring-back is caused by wrongly or
incorrectly operating the saw. It can
beavoidedbysuitableprecautionary
measures, such as those described below.
a) Hold the saw firmly with both hands
and bring your arm into a position in
which you can resist the spring-back
force. Always hold onto the side of the
saw blade and never align the saw
blade with your body.Intheeventofa
spring-back, the circular saw can kick
back, but the operator can keep control
overthespring-backforcesusing
suitable precautionary measures.
b) If the saw blade jams or you interrupt
your work, switch the saw off and keep
it still in the workpiece until the saw
blade has come to a full stop. Never try
to remove the saw from the workpiece
or pull it back as long as the saw blade
is moving, as otherwise it may spring
back. Identify and correct the cause of
the saw blade jamming.
c)
If you want to restart a saw that is in
the workpiece, centre the saw blade in
the sawing gap and check whether the
teeth are jammed in the workpiece. If
thesawbladejams,itcanmoveout
of the workpiece or cause spring-back
when the saw is restarted.
d) Support large plates to reduce the
risk of spring-back due to a jammed
saw blade. Large plates can bend
under their own weight. Plates must be
supported on both sides, not only near
the sawing gap, but also at the edge.
e)
Do not use any blunt or damaged
saw blades. Saw blades with blunt
or improperly aligned teeth cause
increased friction, saw blade jamming
andspring-backduetoanexcessively
tight sawing gap.
f)
Before sawing, fix the cutting depth
and cutting angle settings. If the
settings change during sawing, the saw
blade can jam, resulting in spring-back.
g) Be particularly careful when sawing
existing walls or other areas where
you cannot see what is there.During
sawing, the cutting saw blade can jam
in hidden objects and cause spring-
back.
FUNCTION OF THE BOTTOM GUARD
COVER
a) Before each use, check whether the
bottom guard cover closes properly.
Do not use the saw if the bottom guard
cover does not move freely or close
right away. Never clamp or bind the
bottom guard cover in an open posi-
tion. If the saw accidentally falls to the
ground,thebottomguardcovermay

b) Check the function of the springs for
the bottom guard cover. If the bottom
guard cover and spring do not work
properly, have the saw serviced before
using it.Damagedparts,stickydepos-
