compressed air hose to this. The compressed air hose between the compressed air connection (5) 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 (6) on the compressed air connection (5): using an open-end spanner, secure the compressed air connection against twisting and then screw on the hose connection (6) 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 the compressed air hose on 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 (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 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 regu-

larly maintained with pneumatic oil lubricator. You can do this as follows:

• Use oiled compressed air by fitting an oil-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. Only allow the tool to run at idle speed for a brief period.

1. Place the socket on the square (1) attachment. Ensure that the accessories are fitted securely.

2. To adjust the direction of rotation on the slide switch (2):
