Operation - Metabo DB 10 Original Instructions Manual

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.
- Do not allow the drill bit to rattle on the workpiece:
this will most likely result in much increased vibra-
tion.
- To avoid increasing the level of vibration unneces-
sarily, consumables and the accessory must be
selected, maintained and replaced in accordance
with these instructions.
- To support the weight of the air tool, use a stand,
a clamp or an equaliser whenever possible.
- 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, 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.
- Hoses that whip about 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.
- Ensure that the maximum pressure specified on
the air tool is not exceeded.
- Never carry air tools by the hose.
- Secure the air tool if it is operated in a holder. Loss
of control can cause personal injury.
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
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.

gorised as shown below:

6. Operation

6.1 Before using the tool for the first time
Insert plug-in nipple (8).
6.2 Using the air tool
To benefit from the air tool's full performance,
always use compressed air hoses with an inner
diameter of at least 9 mm. Tool performance can be
significantly impaired if the inner diameter is too
small.
Caution. The compressed air line must not
contain any water condensation.
Caution. To preserve and extend the service
life of this tool, you must ensure that it is regu-
larly maintained with pneumatic oil lubricator. You
can do this as follows:
– Use oiled compressed air by fitting an oil-fog lu-
bricator.
