 The pneumatic tool may not be modified in any way.
Modifications can reduce the effectivity of the safety
measures and increase the risks for the operator.
Service
 Have your pneumatic tool repaired only through a qual-
ified repair person and only using original replacement
parts. This will ensure that the safety of the pneumatic tool
is maintained.
Safety Warnings for Pneumatic Impact Wrenches
 Check if the type plate can be read. If required, provide
for replacement from the manufacturer.
 In case of breakage of the workpiece or an accessory,
or even of the pneumatic tool itself, parts can be
thrown about at high speed.
 During operation, repairs or maintenance, and when
replacing accessories on the pneumatic tool, always
wear shock-resistant eye protection. The degree of the
required protection should be separately evaluated for
each individual application.
 Never switch the pneumatic tool on while carrying it.
Clothing or hair can be caught in a rotating tool holder and
lead to injuries.
 Wear close-fitting gloves. The flow of compressed air
makes the handles of pneumatic tools cold. Warm hands
are less sensitive to vibrations. Loose fitting gloves can be
caught by rotating parts.
 Keep your hands away from the socket drive and the ro-
tating application tool. Never hold a rotating applica-
tion tool or the drive. You could injure yourself.
 Be careful in confined work spaces. Keep hands away
from the reaction bar. Reaction torques may result in in-
juries due to pinching or crushing.
 The operators and the maintenance personnel must be
physically capable to handle the size, weight and pow-
er of the pneumatic tool.
 Be prepared for unexpected movements of the pneu-
matic tool that can develop owing to reaction forces or
breakage of the application tool. Maintain a firm grip
on the pneumatic tool and position your body and arms
to allow you to resist such movements. These precau-
tions can prevent injuries.
 Use auxiliary aids to absorb reaction torque, such as a
supporting fixture. If this is not possible, use an auxilia-
ry handle.
 In case of an interruption of the air supply or reduced
operating pressure, switch the pneumatic tool off.
Check the operating pressure and start again when the op-
erating pressure is optimal.
 When using the pneumatic tool for the performance of
work-related activities, the operator may experience
unpleasant sensations in the hands, arms, shoulders,
neck area or other body parts.
 When working with this pneumatic tool, assume a com-
fortable stance, hold the tool securely and avoid unfa-
vourable positions or such positions, where it is diffi-
cult to keep your balance. For prolonged work, the
1 609 92A 39P | (2.9.16)
operator should change the stance or posture, which
can help avoid discomfort and fatigue.
 Should the operator perceive symptoms such as persis-
tent nausea, discomfort, throbbing, pain, tingling,
numbness, burning or stiffness, these warning signs
should not be ignored. The operator should notify his
employer about the symptoms and consult a qualified
physician.
 Do not touch any socket drives or accessories during
the impact procedure, as this may increase the risk of
cutting, burning or injuries caused by vibrations.
 Only use impact sockets in good working condition. A
defective condition of hand sockets and accessories can
cause them to shatter and be ejected when used with im-
pact wrenches.
 Use appropriate detectors to determine if utility lines
are hidden in the work area or call the local utility com-
pany for assistance. Contact with electric lines can lead
to fire and electric shock. Damaging a gas line can lead to
explosion. Penetrating a water line causes property dam-
age.
 Avoid contact with "live" conductors. The pneumatic
tool is not insulated; contact with a "live" conductor can
lead to an electric shock.
The dust developing during sanding,
WARNING
sawing, grinding, drilling and similar
operations can act carcinogenic, teratogenic or mutagen-
ic. Some of the substances contained in these dusts are:
– Lead in lead-based paints and varnishes;
– Crystalline silica in bricks, cement and other masonry
work;
– Arsenic and chromate in chemically treated wood.
The risk of disease depends on how often you are exposed to
these substances. To reduce the risk, you should work only in
well ventilated rooms with appropriate protective equipment
(e. g. with specially designed respirators that filter out even
the smallest dust particles).
 Wear ear protectors. Exposure to noise can cause hear-
ing loss.
 When working on the workpiece, additional noise can
develop, which can be avoided through appropriate
measures (e. g. by using damping materials on occur-
rence of ringing noise from the workpiece).
 When the pneumatic tool is equipped with a silencer,
always ensure that it is available and in proper working
condition when operating the pneumatic tool.
 Vibration effects may cause damage to the nerves and
blood circulation disorders in the hands and arms.
 If you notice that the skin of your fingers or hands be-
comes numb, tingles, hurts or turns white, stop work-
ing with the pneumatic tool, notify your employer and
consult a physician.
 Do not use worn or poorly fitting socket drives and ex-
tensions. This can lead to intensification of vibrations.
 If possible, use a stand, spring pull/balancer or com-
pensation device in order to support the weight of the
pneumatic tool.
