will electrify the metal parts of the electrical tool as well
and cause an electric shock.
c) Always use saw blades of the correct size and with the
correct mounting hole (e.g. trapezoidal or round sha
pe). Saw blades that do not match the assembly parts
of the saw will not run true and could cause a loss of
control.
d) Never use damaged or incorrect saw blade washers
or screws. The saw blade washers and screws were
designed especially for your saw, for ideal perfor
mance, and operating safety.
2.5 Additional safety instructions for all saws
Backlash – causes and corresponding safety inst-
ructions
- A backlash is a sudden reaction as the result of a
hooked, jammed, or incorrectly aligned saw blade,
which causes the uncontrolled saw to lift and move
out of the workpiece and towards the operator.
- If the saw blade catches or jams in the enclosed saw
gap, it will stick and the motor power will cause the saw
to whip back in the direction of the operator.
- If the saw blade is twisted or incorrectly aligned in the
saw cut, the tooth of the rear saw blade edge can catch
in the wooden surface, which will move the saw blade
out of the saw gap and cause the saw to jump back in
the direction of the operator. A backlash movement is
the result of incorrect or insufficient saw use. This can
be prevented with suitable safety measures as follows.
a) Hold the saw tightly with both hands and move your
arms into a position that enables you to counteract
the backlash forces. In case of a backlash movement,
the circular saw can jump backwards, but the opera-
tor should be able to counteract backlash forces with
suitable safety measures.
b) If the saw blade clamps or you interrupt the work,
switch off the saw and hold it steady in the work
material until the saw blade has come to a stop.
Never try to remove the saw from the workpiece or pull
it backwards while the saw blade edge is moving, since
backlash could result. Determine and correct the cause
of the clamped saw blade.
c) If you want to restart a saw blade that is stuck in the
workpiece, centre the saw blade in the saw gap and
make sure that the saw teeth are not hooked in the
workpiece. If the saw blade is hooked, then it could
move out of the workpiece or cause a backlash when
the saw is started again.

d) Do not use blunted or damaged saw blades. Saw
blades with blunted or incorrectly aligned teeth cause
increased abrasion due to a saw gap that is too tight,
jam the saw blade, and cause backlash movements.
e) Before sawing, lock in the saw depth settings. If you
change the settings during sawing, the saw blade can
jam and cause backlash movements.
f) Be especially careful when sawing into areas that are
not easily visible. The penetrating saw blade may be
jammed by hidden objects and cause backlash
movements.
2.6 Safety instructions for functionality of the
protective hood
a) Prior to every use, ensure that the protective hood
closes smoothly. Do not use the saw if the protec-
tive hood does not move freely and does not
close immediately. Never permanently clamp or bind
the protective hood, since this will cause the saw blade
to be unprotected. If the saw falls onto the floor unin-
tentionally, the protective hood may be bent. Make
sure that the protective hood is able to move freely
and does not touch the saw blade or other parts
in all cutting angles and depths.
b) Check the condition and function of the spring for the
protective hood. Have the saw maintained prior to use
if the protective hood and the spring do not work pro-
perly. Damaged parts, sticky accumulations or crusts
from chips will delay the function of the lower protective
hood.
c) Do not set the saw down on the workbench or the floor
without covering the saw blade with the protective co-
ver. A saw blade that is unprotected as it runs down
moves against the cut direction and saws whatever is
in its path. Observe the run-after time of the saw blade.

2.7 Additional safety warnings

Wear safety goggles.
► Use suitable detectors to determine if utility lines
are hidden in the work area or call the local utility
company for assistance.
Contact with electric lines can lead to fire and electric
shock. Damaging a gas line can lead to explosion.
Penetrating a water line causes property damage or
may cause an electric shock.
