• Never use damaged or incorrect saw blade
clamping flanges or screws. The saw blade
clamping flanges and screws have been specially
designed for your saw, for optimum performance
and operational safety.
• Wear suitable personal protective equipment:
Hearing protection, safety goggles, dust mask with
work that generates dust, protective gloves when
working with rougher materials and with a tool
change.
Kickback - cause and corresponding safety in-
structions
• Kickback is a sudden reaction to a hooked, jammed
or incorrectly aligned saw blade, which leads to an
uncontrolled rebounding of the saw, whereby it
moves out of the workpiece in the direction of the
operator;
• If the saw blade hooks or jams in the closing sawing
gap, it is blocked and the motor power forces the
device back in the direction of the operator;
• If the saw blade skews or is incorrectly aligned in
the saw cut, the teeth of the rear saw blade section
can hook into the surface of the workpiece. This
results in the saw blade jumping out of the sawing
gap and the saw jumps back in the direction of the
operator.
Kickback is the result of incorrect or deficient use of
the saw. It can be prevented by suitable precaution-
ary measures, as described in the following.
• Hold the saw firmly with both hands and bring
your arms into a position in which you can
absorb the kickback forces. Always stand to
the side of the saw blade; never bring the saw
blade in line with your body. During kickback, the
circular saw can jump backwards, although the op-
erator is able to control the kickback forces if suit-
able measures have been implemented.
• If the saw blade jams or you interrupt your
work, release the on/off switch and hold the
saw calmly in the material, until the saw blade
has come to a complete standstill. Never at-
tempt to remove the saw from the workpiece or
draw it backwards whilst the saw blade is mov-
ing, otherwise kickback can occur. Determine
and remedy the cause of the saw blade jamming.
• If you wish to restart a saw that is inserted in
a workpiece, centre the saw blade in the saw-
ing gap and check that the saw teeth are not
hooked in the workpiece. If the saw blade is
jammed, it can move out of the workpiece or cause
kickback when the saw is restarted.
• Support large panels, in order to avoid the risk
of kickback due to a jammed saw blade. Large
panels may bend under their own weight. Panels
must be supported on both sides, close to the saw-
ing gap and at the edge.

• Do not use blunt or damaged saw blades. Saw
blades with blunt or incorrectly aligned teeth cause
increased friction, jamming of the saw blade and
kickback due to the sawing gap being too tight.
• Before sawing, determine the cutting depth
and cutting angle settings. If you change the
settings during sawing, the saw blade can jam and
result in kickback.
• Apply particular caution with "plunge cuts" in
existing walls or other areas that are not vis-
ible. The plunging saw blade can jam in concealed
objects during sawing and result in kickback.
Function of the protective hood
• Check that the protective hood closes correct-
ly before every use. Do not use the saw if the
protective hood does not move freely or does
not close immediately. Never clamp or bind the
protective hood; this would result in the saw
blade being unprotected. If the saw should ac-
cidentally fall to the floor, the protective hood may
be bent.
• Make sure the protective hood moves freely and
does not touch the saw blade or any other parts
with all cutting angles and depths.
• Check the condition and function of the spring
for the protective hood. Have the device main-
tained before use, if the protective hood and
spring do not function properly. Damaged parts,
sticky deposits or adhered chips cause the protec-
tive hood to function with a delay.
• With "plunge cuts" that are not executed at a
right angle, secure the base plate of the saw
against moving. Lateral movement can lead to the
saw blade jamming and therefore also to kickback.
• Do not place the saw on the workbench or the
floor without the protective hood covering the
saw blade. An unprotected saw blade running on
moves the saw against the cutting direction and
saws anything in its path. Observe the run-on time
of the saw here.
Function of the riving knife
• Use the correct saw blade for the riving knife. In
order that the riving knife functions, the disc of the
saw blade must be thinner than the riving knife and
the tooth width must be greater than the riving knife
thickness.
• Never use the saw if the riving knife is bent. Even a
slight disruption can slow the closure of the protec-
tive hood.
Additional safety instructions
• Avoid a blockage in the protective hood (e.g. with
plastics), because this can impair the safety func-
tion.
