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.
– 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. Insert the appropriate accessory in the toolhold-
er (1). Ensure that the accessory is fitted se-
curely.
2. To set the direction of rotation on the rotation
selector switch (3):
= clockwise
= counter-clockwise
3. 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 Chapter on "Technical Speci-
fications".
4. Connect the air tool to the compressed air sup-
ply.
5. To switch on: Press switch (2).
To switch off: Release switch (2)

Adjusting the torque of the safety clutch
- Ensure the work area is clean and tidy; prepare
clean surfaces to lay out the individual parts.
- Using the toolholder (1), secure or fix the tool in
the upper position.
- Figure A: Unscrew the casing (7) (left-handed
thread).
- Figure B: Remove the safety clutch (8). Note that
the guide head (9) and pressure spring (10) can
also fall out here.
- Figure C: Fit the adjusting tools (11) onto the
safety clutch (8). You can increase or reduce the
torque by turning the adjusting tools (11) against
each other. Pay attention to the limit stops in both
directions during this process.
- Remove the adjusting tools (11).
- Clean the component parts and replenish lubrica-
tion if necessary.
- Assemble the component parts. Ensure that the
guide head (9) and the pressure spring (10) are
fitted in the specified position.

- Fit the casing (7) and tighten in place by hand (left-
handed thread). Only tighten by hand - do not use
tools in this case.
- Check that the newly adjusted torque meets your
requirements.

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.
- 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.
