Safety instructions for all saws
a) m DANGER: Do not place your hands in the
sawing area or on the saw blade. Hold the ad-
ditional handle or the motor housing with your
second hand. If both hands hold the circular saw,
the saw blade cannot injure them.
b) Do not reach beneath the workpiece. The
protective hood cannot protect you from the saw
blade beneath the workpiece.
c) Adjust the cutting depth to the thickness of the
workpiece. Less than one full tooth height should
be visible beneath the workpiece.
d) Never hold the workpiece that is to be sawn in
the hand or over the leg. Secure the workpiece
on a stable support. It is important to fasten the
workpiece well, in order to minimise any risk of
physical contact, jamming of the saw blade or loss
of control.
e) When performing work during which the tool
attachment can meet with concealed power
lines or its own mains cable, hold the power
tool by the insulated gripping surfaces. Con-
tact with a live cable will also energise the metal
parts of the electrical tool and will lead to an elec-
tric shock.
f) When performing a longitudinal cut always
use a stop or a straight edge guide. This im-
proves the cutting accuracy and reduces the pos-
sibility of the saw blade jamming.
g) Always use the right size of saw blade and an
appropriate location hole (e.g. star-shaped or
round). Saw blades that do not match the mount-
ing hardware of the saw will run off-centre, causing
loss of control.
h) 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.
i) Wear suitable personal protective equipment:
Hearing protection, safety goggles, dust mask
when working with dust and protective gloves
when changing tools.
Further safety instructions for all saws
Causes and avoidance of kick-back by the user:
• 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 precautionary
measures, as described in the following.
a) 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.
b) 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.
c) If you wish to restart a saw that is inserted in a work-
piece, centre the saw blade in the sawing gap and
check that the saw teeth are not hooked in the work-
piece. If the saw blade is jammed, it can move out of the
workpiece or cause kickback when the saw is restarted.
d) Support large panels to minimise the risk of
saw blade pinching and kickback. Large panels
tend to sag under their own weight. Panels must
be supported on both sides, close to the sawing
gap and at the edge.
e) 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.
f) 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.
g) Apply particular caution with "plunge cuts" in
existing walls or other areas that are not visi-
ble. The plunging saw blade can jam in concealed
objects during sawing and result in kickback.
