tive equipment such as gloves, protective
clothing, a dust mask, non-skid safety shoes, a
safety helmet or ear protectors, to suit the type of
machine and its use, you reduce the risk of injury.
Wearing this equipment is recommended.
4.3 Risks associated with recurring move-
ments
- When working with the air tool, you may experi-
ence an uncomfortable sensation in your hands,
arms, shoulders, neck or in other body parts.
- Make sure you are in a comfortable position to
carry out work with the air tool, check that the tool
is held securely, and avoid any awkward positions
that make it difficult, for example, to keep your
balance. If carrying out work over an extended
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 accessory or accessory part is secured or
replaced.
- Only use accessories that are designed for this
machine and that fulfil the requirements and the
specifications listed in these operating instruc-
tions.
- Never use the chisel as a hand tool. They are
specially designed for application in non-rotating
impact air tools and are correspondingly heat-
treated.
- Never use blunt chisels because they require an
excessive amount of pressure and this can result
in fatigue breakage. Blunt tools can result in
increased vibrations, which is why sharp tools
should always be used.
- Never cool hot accessory parts in water. This can
lead to brittleness and premature failure.
- Never misuse the tool as a lever (e.g. for
mortising); this can result in chisel breakage or
damage. Work in small partial sections to avoid
becoming stuck.
- Avoid any direct contact with the accessory both
during and after use because it may be hot or have
sharp edges.
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.

- Ensure that the spot where you wish to work is free
of power cables, gas lines or water pipes (e.g.
using a metal detector).
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 pneumatic tool must be operated in accord-
ance with the recommendations set forth in these
instructions 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 the minimum of dust is raised in a dust-
filled environment.
- If dust or vapours are generated, the main priority
is to control these at the location where they are
released.
- All built-in 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, it must ensured that
consumables and the accessory are 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 accessory must be
selected, maintained and replaced in accordance
with these instructions.
- The integrated sound absorber must not be
removed. You must ensure it is in good working
order.
