Hazards caused by vibrations
■
Vibrations can damage the nerves and cause
malfunctions to the blood circulation in the
hands and arms.
■
Keep your hands away from the fittings of the
nut wrenches.
■
Wear warm clothing when working in a cold
environment and keep your hands warm and
dry.
■
If you notice that the skin of your fingers or
hands is becoming numb, tingles, hurts or shows
white discolouration, stop working with the
machine and consult a doctor.
■
The automatic screwdriver must to be operated
and maintained in accordance with the recom-
mendations contained in this manual to reduce
any unnecessary increase of the vibrations.
■
Do not use any worn-out or poorly matching
fittings and extensions, as there is a high prob-
ability that this will lead to a significant increase
in the vibrations.
■
Consumables and the machine tool should be
selected, maintained and replaced in accor-
dance with the recommendations in this guide
in order to avoid unnecessary increase of oscil-
lations.
■
If possible, sleeve fittings should be used.
■
To support the weight of the machine, use a
stand, clamp or a balancing unit wherever
possible.
■
Hold the machine securely but not too firmly
while maintaining the necessary hand-reaction
force, as the vibration risk generally increases
the harder the machine is held.
■
An inadequately mounted or damaged acces-
sory tool can lead to excessive vibrations.

Additional safety instructions for
pneumatic machines
■
Compressed air can cause serious injury.
–
When the machine is not in use, the air
supply must always be shut off and the air
hose depressurised. The machine must be
disconnected from the compressed air sup-
ply before replacing accessories or when
conducting repair work.
–
Never aim the airflow at yourself or anyone
else.
■
Thrashing hoses can cause serious injury. There-
fore, always check whether the hoses and their
fixings are undamaged and have not come
loose.
■
Cold air must be directed away from the hands.
■
Do not use any quick-lock couplings on the tool
inlet for impact and impulse drills. For hose con-
nections with a thread, always only use those
made of tempered steel (or a material with
comparable impact resistance).
■
If universal rotary joints (claw couplings) are
used, locking pins must be inserted and Whip-
check hose restraints must be used to provide
protection in the case of a failure of the connec-
tion between the hose and the machine.
■
Ensure that the maximum permissible pressure
on the machine is not exceeded.
■
For torque-controlled machines with continuous
rotation, the air pressure has effects on per-
formance that are relevant in terms of safety.
Requirements for the length and diameter of the
hose must therefore be defined.
■
Never carry pneumatic machines by the hose.
