4.9 Risks associated with vibration
- The effects of vibrations can damage nerves and
impair blood circulation in the hands and arms.
- Keep your hands away from the pin wrench
mounts.
- 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 fingers 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 instruc-
tions and must be maintained in order to avoid
unnecessarily raising the level of vibration.
- Do not use mounts or extensions that are either
worn or badly fitting, since this will most likely
result in greater vibration.
- To avoid increasing the level of vibration unneces-
sarily, the consumables and the mounted tool
must be selected, maintained and replaced in
accordance with these instructions.
- If possible, you should use sleeve fittings.
- To support the weight of the air tool, use a stand,
a clamp or an equaliser whenever possible.
- Hold the air tool firmly but not too tightly using the
required manual torque reaction: the risk of vibra-
tion is increased when the grip force is higher.
4.10 Additional safety instructions
- Compressed air can cause serious injury.
- Whenever the air tool is not in use, and before
replacing 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.
Therefore always check that the hoses and their
fixtures 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
being 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 specified 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.
4.11 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 speci-
fied in the Technical Specifications is not
exceeded.
- Do not overload the tool – use it only within the
performance range for which it was designed (see
"Technical Specifications").
- Use non-hazardous lubricants. Ensure the work-
place 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 influence 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 acci-
dents.
- Keep air tools away from children.
- Do not store the tool outdoors or in damp condi-
tions without protection.
- Protect the air tool, especially the compressed air
connection and the control elements from dust
and dirt.
Information in these operating instructions is cate-
gorised as shown below:

mental damage.
