6. Operation

6.1 Before using the tool for the first time
Prepare the compressed air connection.
Danger! Do not fit quick-lock couplings
directly to the compressed air connection (6).
Never screw the enclosed connection pieces for
quick-lock couplings directly onto the compressed
air connection (6) - simply screw the hose
connection (7) onto the device and then connect the
compressed air hose to this. The compressed air
hose between the compressed air connection (6)
and a quick-lock coupling must be at least 20 cm in
length. If fitted too close to the device, a quick-lock
coupling may fail: whiplashing hoses can cause
serious injury as a result.
- Screw the enclosed hose connection (7) on the
compressed air connection (6): Using an open-
end spanner, secure the compressed air connec-
tion against twisting and then screw on the hose
connection (7) with another open-end spanner.
See page 2, fig. A.
- Fit the enclosed double ear hose clamp onto the
compressed air hose that you want to connect.
- Push along the compressed air hose until it meets
the stop on the hose connection.
- Slide the double ear hose clamp onto the hose
connection. Using a suitable pliers, pinch the two
ears together (see Page 2, Fig. B).
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.
– 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 10 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. Do not run the tool at idle speed.
1. Install tool: fit retaining spring (2) on chisel (1)
as shown on page 2. Insert chisel in chisel hold-
er (3) and then screw retaining spring (2) onto
air tool as far as the stop.
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
12
pressure, see the Chapter on "Technical Speci-
fications".
3. Connect the air tool to the compressed air sup-
ply.
4. Place chisel on workpiece to be processed.
5. To switch on: Press switch (4).
To switch off: Release switch (4)
.

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.
- To prevent deposits of dust and foreign bodies,
apply a few drops of oil to the chisel holder every
2 operating hours.
- 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.
