Hazards due to vibrations
Vibrations can cause damage to the nerves and
impairment of the circulation in the hands and
arms.
Keep your hands away from the sockets of the
nut wrench.
When working in a cold environment, wear
warm clothing and keep your hands warm and
dry.
f you detect that the skin on your fingers or
hands becomes numb, tingles, aches or becomes
white stop working with the tool, inform your
employer and consult a doctor.
The threaded fastener tool must be operated and
maintained according to the recommendations in
this manual, to avoid an unnecessary amplifica-
tion of the vibrations.
Do not use any worn or poorly fitting sockets and
extension bars, because it is extremely likely that
this will lead to a considerable amplification of
the vibrations.
The consumables and the tool bit must be
selected, maintained and replaced according to
the recommendations of this manual, to prevent
an unnecessary amplification of the vibrations
here possible sleeve fittings must be used
Wherever possible use a column, clamp or an
equaliser to support the weight of the tool.
Do not hold the tool too tightly but with a secure
grip while maintaining the necessary hand reac-
tion forces because the risk of vibration generally
increases with increasing gripping force.

S ecial safety instructions
Additional safety instructions for
pneumatic tools
Compressed air can cause serious injuries.
If the tool is not in use, before exchanging acces-
sories or when performing repair work, always
shut o the air supply, depressurise the air hose
and disconnect the tool from the compressed air
supply.
Never direct the air ow towards yourself or
anybody else.
Flailing hoses can cause serious injuries.
Therefore always check whether hoses and their
fastenings are undamaged and have not come
loose.
Direct cold air away from the hands.
Do not use quick-release couplings at the tool
inlet with impact and impulse drives. Only use
threaded hose connectors made from hard-
ened steel (or a material of comparable impact
strength).
Ensure that the maximum pressure indicated on
the tool is not exceeded.
If universal rotational couplings (claw couplings)
are used, lock pins must be used together with
whip-check hose clips to provide protection in the
event of failure of the hose connection to the tool
or of connections between hoses.
For torque-controlled tools with continuous rota-
tion, the air pressure has safety relevant e ects
on the performance. Therefore hose length and
diameter re uirements must be specified
Never carry air tools by the hose.
