period, the operator should change position occa-
sionally. This should help to avoid fatigue and any
unpleasant sensation.
- If the operator experiences persistent symptoms
such as feeling unwell, aches, pains or throbbing,
a prickling or burning sensation, loss of hearing, or
joint stiffening, these warning signs must not be
ignored. The operator should advise the employer
of these symptoms and consult a qualified doctor.
4.4 Risks associated with accessory parts
- Disconnect the air tool from the air supply before
the mounted tool or accessory part is secured or
replaced.
- Only use accessories that are designed for this
device and that fulfil the requirements and the
specifications listed in these operating instruc-
tions.
4.5 Risks in the workplace
- Slipping, tripping and falling are the main reasons
for accidents in the workplace. Pay attention to
surfaces that may have become slippery as a
result of using the air tool, and also watch that the
air hose does not cause someone to trip.
- Proceed carefully when working in unfamiliar envi-
ronments. Power cables and other supply lines
may represent a hidden risk.
- The air tool is not designed for use in explosive
environments and is not insulated against contact
with sources of electric power.
4.6 Risks associated with dust and vapours
- The dust and vapours generated when the air tool
is used may carry health risks (e.g. cancer, birth
defects, asthma and/or dermatitis); it is therefore
imperative that a risk assessment is carried out in
relation to these risks and that suitable controls
are then implemented.
- The risk assessment should take into account
both the dust generated while the air tool is used
and any existing dust that may be raised during
operation.
- The air tool must be operated in accordance with
the recommendations set forth in these instruc-
tions and must be maintained in order to minimise
the release of dust and vapours.
- The extracted air must be discharged in such a
way that, in a dust-filled environment, the
minimum of dust is raised.
- If dust or vapours are generated, the main priority
is to control these at the location where they are
released.
- All integral or accessory parts on the air tool that
are designed to collect, extract or prevent airborne
dust or vapours must be used and maintained in
accordance with the manufacturer's instructions.
- To avoid increasing the amount of dust or vapours
generated unnecessarily, consumables and the
mounted tool must be selected, maintained and
replaced in accordance with these instructions.
- Use protective breathing apparatus in accordance
with your employer instructions or in accordance
with health and safety regulations.

4.7 Risks associated with noise
- Failure to use adequate ear protectors when the
noise level is high can result in lasting damage to
hearing, hearing loss and other problems, such as
tinnitus (ringing, whistling or buzzing in the ear).
- It is vital to carry out a risk assessment in relation
to these risks and to implement appropriate
control measures that take the risks into account.
- Appropriate risk control measures may include,
for example, the use of sound-insulating materials
to prevent the knocking sounds that occur on the
workpieces.
- 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 instruc-
tions and must be maintained in order to avoid
unnecessarily raising the noise level.
- To avoid increasing the noise level unnecessarily,
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 working order.
4.8 Risks associated with vibration
- The effects of vibrations can damage nerves and
impair blood circulation in the hands and arms.
- 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.
- To avoid increasing the level of vibration unneces-
sarily, consumables and the mounted tool must be
selected, maintained and replaced in accordance
with these instructions.
4.9 Additional safety instructions
- Compressed air can cause serious injury.
- When 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.
- If universal swivel couplings (claw couplings) are
being used, locking pins must also be used. 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.
