Kickback and corresponding safety
instructions
Kickback is a sudden reaction caused when a
rotating attachment part, e.g. grinding disc, abra-
sive band, wire brush, etc. catches or jams.
Catching or jamming leads to an abrupt stop of the
rotating attachment part. If this happens, an uncon-
trolled power tool will turn rapidly against the
direction of rotation of the attachment part.
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 improper or incorrect use
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 body and arms, so that they
can absorb the kickback forces. By taking
adequate precautions, the operator can stay in
control of the kickback forces.
b) Take special care when working around
corners, sharp edges, etc. Avoid allowing the
attachment part to bounce back from the work-
piece or jam in the workpiece. The rotating
accessory tool is more likely to jam in corners or
sharp edges or if it rebounds off them. This can
cause a loss of control or kickback.
e) Do not use toothed saw blades. Such accesso-
ries often cause a kickback or loss of control
over the power tool.
d) Always move the attachment part in the
material in the same direction as the direction
in which the cutting edge leaves the material
(in other words, the same direction in which
the chips are thrown out). Guiding the power
tool in the wrong direction will cause the cutting
edge of the accessory tool to jump out of the
workpiece which can lead to the accessory tool
being pulled in this direction.

e) Always fix the workpiece when using rotary
files, cutting discs, high-speed milling tools or
hard-metal tools. Even a minimal tilting in the
groove can cause these tools to jam and lead
to a kickback. When the cutting disc jams, it
usually breaks. When a rotary file, high-speed
milling tool or hard-metal milling tool jams, the
accessory tool can jump out of the groove and
lead to loss of control of the power tool.
Supplementary safety instructions
for grinding and abrasive cutting
Special safety instructions for grinding and
abrasive cutting
a) Use only the grinding accessories approved
for your power tool and only for the recom-
mended applications. Example: Never grind
with the side surface of a cutting disc. Cutting
discs are designed to remove material with the
edge of the disc. Any lateral application of
force on these grinding tools can lead to a
breakage.
b) Use only undamaged mandrels of the correct
size and length and without undercut on the
shoulder for conical and straight pencil
grinders. Using an appropriate mandrel
reduces the risk of breakages.
c) 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 blocking and
thus the possibility of a setback or a breakage
of the grinding tool.
d) Avoid putting your hand in the area in front
of or behind the rotating cutting disc. When
you move the cutting disc away from your hand,
it is possible, in the event of a kickback, that the
power tool along with the rotating disc could be
thrown out directly towards you along with the
rotating disc.
e) 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 a kickback. Identify and
remove the cause of the jam.
