6.8 Using the air tool
Always guide the machine with both hands.
Switch the machine on first before mounting it
on the workpiece.
After switching off the machine, only set it
down when the motor has come to a standstill.
To benefit from the air tool's full performance,
always use compressed air hoses with an inner
diameter of at least 10mm. 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.
– Without an oil-fog lubricator: manually apply oil
every day via the compressed air connection.
Use approx. 3-5 drops of pneumatic oil lubricator
for each 15 minutes of continuous operation.
If the tool has not been in use for several days, you
should manually apply about 5 drops of pneumatic
oil lubricator into the compressed air connection.
Caution. Only allow the tool to run at idle
speed for a brief period.
1. Fit a suitable sanding belt (13) (see Section
6.4).
2. Adjust the supply pressure (this is measured at
the air outlet while the air tool is switched on).
For details of the maximum permissible supply
pressure, see the section on "Technical Specifi-
cations".
3. Connect the air tool to the compressed air sup-
ply.
4. To switch on: press switch (4).
Set the rotational speed on the adjusting screw
(9). (The best way to determine the ideal setting
is through a practical trial).
To switch off: release switch (4).
5. Do not press the device too firmly against the
surface being sanded. This does not improve,
but rather impairs, the sanding performance.
6. For optimum operation: sand on the side on
which the sanding belt moves towards the ma-
chine.

7. Care and Maintenance

Danger! Disconnect the compressed air con-
nection before carrying out any work.
Danger! Repair and maintenance work other
than described in this section should only be
carried out by qualified specialists.
- Carry out regular maintenance to ensure the
safety of the air tool.
- Check that all screw fittings are seated securely,
and tighten if necessary.
14
- Clean the filter in the compressed air connection
at least once a week.
- It is recommended that you install a pressure
reducer with an air-water separator and lubricator
upstream of the air tool.
- If a large amount of air or oil is escaping, check the
air tool and have it maintained if necessary. (see
Section 9.)
- Check the rotational speed regularly and after
every use. Also carry out a simple check on vibra-
tion emission.
- Avoid contact with dangerous substances that
have collected on the tool. Wear suitable personal
protective equipment and take appropriate meas-
ures to remove any dangerous substances before
maintenance.
