Additional safety instructions for all
Kickback and corresponding safety instruc-
Kickback is a sudden reaction caused when a
rotating accessory tool, e.g. grinding disc, abrasive
band, wire brush, etc., catches or jams. Catching
or jamming leads to an abrupt stop of the rotating
accessory tool. If this happens, an uncontrolled
power tool will turn rapidly against the direction
of rotation of the accessory tool.
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.
PFBS 12 A1
a) Hold the power tool ﬁrmly in both hands and
position your body and arms so they can
absorb the force of a kickback. 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
accessory tool 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.
c) Do not use toothed saw blades. Such acces-
sories often cause a kickback or loss of control
over the power tool.
d) Always move the accessory tool in the same
direction in the material in which the cutting
edge leaves the material (in other words, the
same direction in which the dust is 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.
