r) Do not use the power tool in the vicinity of
flammable materials. Sparks can ignite such
materials .
s) Do not use any accessory tools which require
liquid coolant. The use of water or other liquid
coolants may lead to electric shock .

for all applications
Kickback and corresponding safety
instructions
Kickback is a sudden reaction caused when a
rotating accessory tool, e .g . grinding disc, grinding
band, wire brush, etc ., catches or jams and 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 improper or incorrect use
of the power tool . This can be avoided by taking
proper precautions as described below .
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 on corners,
sharp edges, etc. Avoid allowing the accessory
tool to bounce back from the workpiece 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 .
PFBS 12 B4
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 clamp the workpiece when using
rotary files, cutting discs, highspeed milling
tools or hardmetal tools. Even a minimal tilting
in the groove can cause these tools to jam and
lead to a kickback . When a 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 breakage .
b) For conical and straight pencil grinders, use
only undamaged mandrels of the correct size
and length and without an undercut on the
shoulder. 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 jamming and
thus the possibility of kickback or 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 .
