Always use the right size of saw blade and an
•
appropriate location hole (e.g. star-shaped or
round). Saw blades that do not fit with the mount-
ing parts of the saw will run out­of­centre and re-
sult in a loss of control.
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 direc-
tion of the operator;
If the saw blade hooks or jams in the closing saw-
•
ing 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 sec-
tion 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 direc-
tion of the operator.
Kickback is the result of incorrect or deficient use
•
of the saw. It can be prevented by suitable precau-
tionary 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
operator is able to control the kickback forces if
suitable 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 acci-
dentally 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
protective 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 kick-
back.
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 run­on time
of the saw here.
