clothes may be accidentally caught in
the rotating tool insert and the insert
may injure you.
n Regularly clean the ventilation slots
of your electrical tool. The motor fan
draws dust into the housing, and a
large build up of metal dust can lead
to electrical risks.
o Never use the electrical tool in the
vicinity of flammable materials.
Sparks may set fire to these materials.
p Never use tool inserts that require
liquid coolant. The use of water or
other liquid coolant may cause an
electrical shock.
III. Further safety notes for all
applications
Kickback and the appropriate
warning notes
Kickback is the sudden reaction that
follows on from a stuck or blocked
rotating tool insert, such as a sanding
disc, sanding plate, wire brush etc.
Sticking or blocking leads to an abrupt
stopping of the rotating tool insert. This
results in an uncontrolled electrical tool
accelerating against the direction of
rotation of the tool insert at the point at
which it is blocking.
If, for example, a sanding disc becomes
stuck or blocked in the workpiece, it is
possible for the edge of the disc caught
in the workpiece to become stuck and
the disc breaks out or causes kickback.
The disc then either moves towards the
operator or away from them, depending
on the direction of rotation of the disc at
the point of the blockage. Sanding discs
may also break during this process.

A kickback is a consequence of
incorrect or faulty operation of the
electrical tool. It can be prevented by
the use of suitable safety measures, as
described below.
a Hold the electrical tool securely with
both hands and position your body
and arms in such a way that you are
able to absorb any kickback. Always
use an additional handle, if available,
to ensure you have the greatest
possible level of control over the
kickback forces or reaction torque
when starting up. The operator is able
to control kickback and reaction forces
by means of the appropriate safety
measures.
b Never bring you hand close to the
rotating tool insert. The tool insert
may move over your hand in the
event of kickback.
c Position your body in such a way that
it is not located where the electrical
tool is likely to kickback to. The
kickback will push the electrical tool in
the direction opposite to the movement
of the disc at the blockage point.
d Be especially careful around
corners, sharp edges etc. Prevent
insert tools from bouncing off the
workpiece and becoming jammed.
The rotating tool insert tends to
become jammed at corners, sharp
edges or when it bounces. This will
lead to a loss of control or kickback.
e Do not use a chain or toothed saw
blade. Such tools often cause kick
back or the loss of control of the
electrical tool.
