Operation
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 openend spanner, secure the compressed air connection against twisting and then screw on the hose connection (7) with another open-end spanner. Fig. A.
-
Fit the enclosed double ear hose clamp onto the compressed air hose that you want to connect.
-
Push the compressed air hose onto the hose connection as far as it will go.
-
Slide the double ear hose clamp onto the hose connection. Using a suitable pliers, pinch the two ears together ( Fig. B).
Attaching the auxiliary handle
Danger! Only work when the auxiliary handle is attached! Attach the
auxiliary handle securely to the device using the screws provided. Firmly
tighten thescrews with the Allen keys provided.
Danger! Always hold the machine with both hands using the handles
provided, stand securely and concentrate.
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 10 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 regularly maintained with pneumatic oil lubricator. You can
do this as follows:
- Use oiled compressed air by fitting an oil-fog lubricator.
- 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. Only allow the tool to run at idle speed for a brief period.
- Place the socket on the square (1) attachment. Ensure that accessories are fitted securely.
- To set the direction of rotation and the torque on the rotation selector switch (8):
- = clockwise
- = counter-clockwise
- 1 = low torque
- 2 = medium torque
- 3 = high torque
- 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 Specifications”.
- Connect the air tool to the compressed air supply.
- To switch on: press switch (4). To switch off: release switch (4)
