Additional safety instructions
• Compressed air can cause serious injury.
• Whenever the air tool is not in use, and before replac-
ing accessory parts or when carrying out repairs, you
must ensure that air supply is shut off, that the air hose
is depressurised and that the air tool is disconnected
from the compressed air supply.
• Never direct the air jet at yourself or other people.
• Whiplashing hoses can cause serious injury. There-
fore always check that the hoses and their xtures
are in good condition and that they have not become
loose.
• Cold wind should be directed away from the hands.
• Do not use quick-lock couplings on the tool inlet. For
threaded hose connections, only use those made
with hardened steel (or a material with similar shock
resistance).
• If universal swivel couplings (claw couplings) are be-
ing used, locking pins are also required. You should
also use whip check hose restraints in case there is
a problem with the connection between the hose and
air tool or between the hoses themselves.
• Ensure that the maximum pressure specied on the
air tool is not exceeded.
• Never carry air tools by the hose.
• Secure the air tool if it is operated in a holder. Loss
of control can cause personal injury.
Additional safety instructions
• If applicable, observe any particular health and safety
or accident prevention regulations governing the use
of compressors and compressed air tools.
• Ensure that the maximum supply pressure specied
in the Technical Specications is not exceeded.
• Do not overload the tool – use it only within the perfor-
mance range for which it was designed (see “Techni-
cal Specications”).
• Use non-hazardous lubricants. Ensure the workplace
is adequately ventilated. If there is a large amount of
discharge: check the air tool and have it repaired if
necessary.
• Do not operate the tool unless you are completely
focused. You must be alert, pay attention to what you
are doing and proceed cautiously when working with
an air tool. Never use a tool when you are tired or
under the inuence of drugs, alcohol or medication.
Just one moment‘s carelessness when using the tool
can cause serious injury.
• Make sure your workplace is clean and well lit. Untidy
or poorly lit workplaces can cause accidents.
• Keep air tools away from children.
• Do not store the tool outdoors or in damp conditions
without protection.
• Protect the air tool, especially the compressed air
connection and the control elements from dust and
dirt.
• Appropriate risk control measures may include, for
example, the use of sound-insulating materials to
prevent the knocking sounds that occur on the work-
pieces.
• Use ear protection in accordance with your employer
instructions or in accordance with health and safety
regulations.
• The air tool must be operated in accordance with the
recommendations provided in these instructions and
must be maintained in order to avoid unnecessarily
raising the noise level.
• To avoid increasing the noise level unnecessarily, the
consumables and the mounted tool must be selected,
maintained and replaced in accordance with these
instructions.
• The integrated sound absorber must not be removed.
You must ensure the sound absorber is in good work-
ing order.
Hazards due to vibrations
The device is not designed for working over extended
periods of time. In case of extended working periods, the
operating personnel may suffer circulatory disturbances
in their hands (vibration white nger) due to vibrations.
Vibration white nger is a vascular disease in which
small blood vessels on the ngers and toes suddenly
cramp. The affected areas are no longer supplied with
sufcient blood and therefore appear extremely pale.
The frequent use of vibrating devices can cause nerve
damage in people whose circulation is impaired (e.g.
smokers, diabetics). If you notice unusual adverse ef-
fects, stop working immediately and seek medical ad-
vice. Observe the following information to reduce haz-
ards: Keep your body and especially your hands warm in
cold weather. Take regular breaks and move your hands
to promote circulation. Make sure that the machine emits
the least vibration possible through regular maintenance
and xed parts on the device.
• When working in cold environments, you must wear
warm clothing and keep your hands warm and dry.
• If you notice that the skin on your ngers or hands is
numb, prickling or turning white, stop working with the
air tool immediately, notify your employer and consult
a doctor.
• The air tool must be operated in accordance with the
recommendations provided in these instructions and
must be maintained in order to avoid unnecessarily
raising the level of vibration.
• Do not hold the mounted tool with your free hand
because this results in an increased vibration effect.
• When working on concrete, knock out small parts with
crushers to avoid jamming of the tool.
• Move the cutting tool of crushers every couple of sec-
onds. Stop the crusher when you raise the air tool to
change its position. Otherwise strong vibrations can
result when you lift up the air tool by the handles.
• Hold the air tool rmly but not too tightly using the
required manual torque reaction: the risk of vibration
is increased when the grip force is higher.
