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 appli
cations
Kickback and appropriate safety
notes
Kickback is the sudden reaction that fol-
lows on from a stuck or blocked rotat-
ing 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 acceler-
ating 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 incor-
rect 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 availa
ble, 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 elec-
trical tool in the direction opposite
to the movement of the disc at the
blockage point.
d Be especially careful around cor
ners, 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 elec-
trical tool.
Additional safety precautions for
grinding and separating:
Special safety precautions for grind
ing and separating:
a Use only grinding tools expressly
permitted for use with your electri
cal tool and the appropriate protec
tive hood for these grinding tools.
Grinding tools which are not designed
for use with the electrical tool cannot
be properly shielded and are unsafe.
b Cropped grinding discs must be
mounted in such a way that their
grinding surface does not protrude
