Kickback - causes and corresponding safety
instructions
▯ Kickback is a sudden reaction caused when a
rotating grinding disc catches or jams. Catching
or jamming causes the rotating accessory tool
to stop abruptly. If this happens, an uncontrolled
power tool turns rapidly against the direction
of rotation of the accessory tool caught in the
blockage.
▯ If, for example, a grinding disc catches or jams,
the edge of the grinding disc that is projecting
into the workpiece can get caught and break
off the grinding disc or cause a kickback. The
grinding disc can then fly in the direction of the
operator or away from him, depending on the
direction of rotation of the disc at the blockage.
This can also break grinding discs.
A kickback is caused by incorrect use or misuse
of the power tool. This can be avoided by taking
proper precautions as given below.
a) Hold the power tool firmly in both hands and
position your arms so they can absorb the
force of a kickback. Always use the additional
handle, if available, so you have the maximum
control over the kickback force or reaction
torques at full speed. By taking adequate pre-
cautions, the operator can stay in control of the
kickback and reaction torques.
b) Never hold your hand close to a rotating
accessory tool. The accessory tool could hit
your hand in the case of a kickback.
c) Avoid the area in front of and behind the rotat-
ing cutting disc. The kickback will force the power
tool in the opposite direction to the direction of
rotation of the grinding disc at the blockage.
d) Take special care when working around
corners, sharp edges, etc. Avoid allowing
the accessory tool to bounce back from the
workpiece or jam. The rotating accessory tool
is more likely to jam in corners or sharp edges
or if it bounces. This can cause a loss of control
or kickback.

e) Do not use a toothed or chain saw blade or
segmented diamond-coated disc with more
than 10 mm wide slits. Such accessory tools
cause a kickback or loss of control over the
power tool.
f) Avoid cutting disc jams or excessive contact
pressure. Do not make any excessively deep
cuts. Overloading the cutting disc increases the
stress and likelihood of tilting or jamming and
thus the possibility of kickback or breakage of
the grinding tool.
g) If the cutting disc jams or you stop working,
switch the tool off and hold it steady until the
disc has completely stopped turning. Never
attempt to pull a rotating cutting disc out of a
cut. This could lead to kickback. Identify and
remove the cause of the jam.
h) Do not switch the power tool back on as long
as it is in the workpiece. Allow the cutting disc
to reach its full speed before you carefully
continue the cut. Otherwise, the disc may jam,
jump out of the workpiece or cause kickback.
i) Support panels or large workpieces to reduce
the risk of the cutting disc jamming and causing
a kickback. Large workpieces can bend under
their own weight. The workpiece must be sup-
ported on both sides, namely in the vicinity of
the cut and also at the edge.
j) Be particularly careful when making "pocket
cuts" into existing walls or other obscured
areas. The inserted cutting disc may cut into
gas or water pipes, electrical wiring or other
objects that can cause kickback.
