Only use lubricants that have been recommended
by the manufacturer.
Wear personal protective equipment and always
wear safety glasses. By wearing personal protec-
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.
Check the grinding wheel before each use. Do not
use if cracked or broken, or if it has been dropped.
Avoid direct contact with the grinding wheel to
prevent crushing or cutting your hands or other
body parts. To protect your hands, wear suitable
gloves.
Never operate the machine when no grinding
medium is installed.
There is a risk of electrostatic discharge if the
machine is used on plastic and other non-conduc-
tive materials.
Explosive or flammable dust or vapours may be
generated while you work on workpieces. There is
therefore a risk of explosion or fire. Always use a
dust extraction or dust suppression system that is
suitable for the material being processed.
4.4 Risks associated with recurring move-
ments
When working with the air tool, you may experience
an uncomfortable sensation in your hands, arms,
shoulders, neck or 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, you/
the operator should change position occasionally.
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.
4.5 Risks associated with accessory parts
Disconnect the air tool from the air supply before
securing or replacing the mounted tool or accessory
part.
Only use accessories that are designed for this
device and that fulfil the requirements and the spec-
ifications listed in these operating instructions.
Avoid any direct contact with the mounted tool both
during and after use because it may be hot or have
sharp edges.
Parting grinder discs and chopping machines must
not be used.
The rated speed of the mounted tool must be at
least equal to the maximum speed marked on the
air tool. Accessories running faster than their rated
speed can break and fly apart.
Self-adhesive sanding discs must be fitted concen-
trically on the supporting disc.
4.6 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 be careful that the air
hose does not cause someone to trip.
The air tool is not designed for use in explosive envi-
ronments and is not insulated against contact with
sources of electric power.
Ensure that the area where you wish to work is free
of power cables, gas lines or water pipes (e.g. by
using a metal detector).
4.7 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 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, 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 point 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 accord-
ance with the manufacturer's instructions.
To avoid increasing the amount of dust or vapours
generated unnecessarily, the 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.
4.8 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.
