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 cutting disc jams, it usually
breaks. When a rotary ﬁle, high-speed milling
tool or hard-metal milling tool jams, the acces-
sory 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
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 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 re-
duces 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 jamming and
thus the possibility of kickback or breakage of
the grinding tool.
d) Avoid putting your hand in the area in front
of and 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.
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 kickback. Identify and
remove the cause of the jam.
PMGS 12 C3
f) 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.
g) Support panels or large workpieces to re-
duce the risk of the cutting disc jamming and
causing a kickback. Large workpieces can
bend under their own weight. The workpiece
must be supported on both sides, namely in the
vicinity of the cut, and also at the edge.
h) 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.
Supplementary safety instructions
for working with wire brushes
Special safety instructions for working with
a) Be aware that the brush can lose wire bristles
even during normal operation. Do not over-
stress the wires by applying excessive pres-
sure to the brush. The wire bristles can easily
penetrate light clothing and/or skin.
b) Allow the brush to run at working speed for
at least one minute before applying it to the
workpiece. Ensure that no one is standing in
front of or in line with the brush during this
time. Loose pieces of wire could ﬂy oﬀ during
the run-in period.
c) Aim the rotating steel brush away from your-
self. When working with these brushes, small
particles and minute pieces of wire can ﬂy oﬀ
at great speed and pierce skin.
Safety instructions for drills
Loss of control can lead to injuries.
Hold the appliance by the insulated handles
when you are carrying out work during which
the deployed tool may come into contact with
concealed power cables or its own power
cable. Contact with a live cable can also make
metal parts of the appliance live and could
result in an electric shock.
