 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 when working conditions are tight. Danger
of injury from pinched or caught fingers due to reaction
torque.
 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
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 ex-
posed to these substances. To reduce the risk, you should
work only in well ventilated rooms with appropriate protec-
tive 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.
