your fi ngers or hands has become pale, stop
working with the mini die grinder and consult a
doctor.
■
The mini die grinder must be operated and
maintained in accordance with the recommen-
dations contained in this manual to reduce any
unnecessary increase in vibration.
■
Consumables/machine tools must be selected,
maintained and replaced in accordance with
the recommendations in this guide in order to
avoid unnecessary increase in vibration.
■
Always use a stand, a clamp or a compensation
device to support the weight of the machine.
■
Hold the machine securely but not too fi rmly
while maintaining the necessary hand-reaction
force, as the vibration risk generally increases
the harder the machine is held.
■
An inadequately mounted or damaged ma-
chine tool can lead to excessive vibrations.
Additional safety instructions for
pneumatic machines
■
Compressed air can cause serious injury.
Ensure that the air supply is switched off , the
hose is not under pressure and that the machine
is disconnected from the air supply when the
machine is not in us, and also before exchang-
ing accessories or carrying out repairs. Never
aim the airfl ow towards yourself or any other
person.
■
Thrashing hoses can cause serious injury.
Therefore, always check that the hoses and
their fi xings are not damaged or have not come
loose.
■
If universal rotary joints (claw couplings) are
used, locking pins must be used to provide pro-
tection; Whipchek® air hose restraints must be
used to provide protection in case of a failure at
the connection of the hose to the machine.
■
Ensure that the maximum permissible pressure
stated on the machine is not exceeded.
■
Never carry compressed-air-powered machines
by the hose.
Hazards caused by accessories
■
Disconnect the grinder for whetstones from the
power supply before fi tting or replacing the
machine tools or accessories.
■
Use only accessories and consumables of the
size and type recommended by the manufacturer
of the grinder for whetstones.
■
Avoid direct contact with the machine tool during
and after use, since this can have heated up or
have become sharp.
■
The maximum operating speed recommended
by the manufacturer of the grinder for whetstones
must be the same or higher than the rotational
speed labelled on the machine.
■
Never fi t a grinding disc, cut-off disk or milling
cutter to a grinder for whetstones. A bursting
grinding disc can lead to extremely serious
injuries or death.
■
Do not use discs which are damaged, cracked
or could have fallen down.
■
Only approved machine tools with the correct
shaft diameter may be used.
■
Please note that you must ensure that the per-
missible rotational speed of small grinding
tools is reduced due to raising the position of
the shaft between the end of the chuck and the
small grinding tool (overhang). You must ensure
that the minimum clamping length of 10 mm is
retained (see Figure 1).
min. 10 mm

■
You must be aware that there is a danger of
mismatching between the shaft diameter of the
small grinding tool and of the chuck.
