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.
4.9 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.
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.
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 discon-
nected from the compressed air supply.
Never direct the air jet at yourself or other people.
Whiplashing hoses can cause serious injury. There-
fore always check that the hoses and their fixtures
are in good condition and that they have not
become loose.
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.
Ensure that the maximum pressure specified on the
air tool is not exceeded.
Never carry air tools by the hose.
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
12
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.
- Dust from material such as paint containing lead,
some wood species, minerals and metal may be
harmful. Contact with or inhalation of the dust may
cause allergic reactions and/or respiratory
diseases to the operator or bystanders.
Certain kinds of dust are classified as carcino-
genic, such as oak and beech dust, especially in
conjunction with additives for wood conditioning
(chromate, wood preservative). Material
containing asbestos must only be treated by
specialists.
- Use a dust extraction device where possible.
- For efficient dust collection, use a suitable
Metabo vacuum cleaner together with this air
tool.
- The workplace must be well ventilated.
- The use of a dust mask of filter class P2 is
recommended.
- Follow national requirements for the materials you
want to work with.
- Materials emitting dusts or vapours that may be
harmful to health (e.g. asbestos) must not be
processed.
- Secure the workpiece against slipping, e.g. with
the help of clamping devices.
- Flying sparks are created when sanding metal.
Ensure that no persons are in danger. Due to the
risk of fire, all combustible materials must be
removed from the work area (area affected by
flying sparks).
- Use of a fixed extractor system is recommended.
- Always guide the machine with both hands on the
handles provided. Loss of control can cause
personal injury.
- Never place your hand near rotating parts of the
device or near the rotating sanding belt.
- Remove sanding dust and similar material only
when the machine is not in operation.
- The rated speed of the sanding belt must be at
least equal to the specified belt speed in idling. A
sanding belt running faster than its rated speed
can break and fly apart.
- Check prior to each use that the sanding belt is
correctly attached and is completely on the rollers.
Carry out a trial run: allow the machine to run at
idling speed for 30 seconds in a safe location.
Stop immediately if significant vibrations occur or
if other defects are noted. If such a situation
occurs, check the machine to determine the
cause.

gorised as shown below:
