Metabo DG 25 Set Notice D'utilisation Originale page 11

- Make sure you hold the pneumatic tool correctly:
Be prepared to counter any standard or unex-
pected movements, so keep both hands ready.
- Ensure you stand in a safe position and keep your
balance at all times.
- Avoid accidental operation. If the air supply is
interrupted, switch off the pneumatic tool using the
On/Off switch.
- 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.
- The rated speed of the accessory must be at least
equal to the maximum speed marked on the pneu-
matic tool. Accessories running faster than their
rated speed can break and fly apart.
- Wear a safety helmet if carrying out work above
your head.
- The tool continues running after the pneumatic
tool has been switched off.
- Ensure the sparks emitted during use do not pose
any risk. Explosive or flammable dust may be
generated while you work on workpieces. There is
therefore a risk of explosion or fire.
4.4 Risks associated with recurring move-
ments
- When working with the pneumatic tool, you may
experience 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 pneumatic 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 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 pneumatic 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.
- Avoid any direct contact with the accessory both
during and after use because it may be hot or have
sharp edges.
- The rated speed of the accessory must be at least
equal to the maximum speed marked on the pneu-
matic tool. Accessories running faster than their
rated speed can break and fly apart.
- Never fit a grinding wheel, cut-off wheel or milling
cutter. If a grinding wheel burst, it can cause
serious or even fatal injury.
- Do not use wheels that are chipped, ripped or that
may have fallen.
- Only the permissible accessories with the appro-
priate shank diameter must be used.
- Observe the manufacturer's recommendations for
small grinding tools. For small grinding tools, the
maximum permissible projection allowed by the
manufacturer (L =length of shank between the
0
end of the collet chuck and the small grinding tool)
must not be exceeded! If the projection is
increased (L ), the permissible speed must be
0
lowered. Insert the accessory with the full length of
the shank if possible into the collet chuck. Ensure
that the clamping length (L

g
- The accessory's shank diameter must correspond
exactly to the collet bore of the collet chuck!
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 slippy as a result
of using the pneumatic 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 pneumatic 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).
4.7 Risks associated with dust and vapours
- The dust and vapours generated when the pneu-
matic 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 suit-
able controls are then implemented.
- The risk assessment should take into account
both the dust generated while the pneumatic 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 pneumatic
tool that are designed to collect, extract or prevent
