Operation
between the air sander and the air hose, but use the supplied quick
coupling adaptor (11) instead. Seal the end of the quick coupling
adaptor (11) with Teflon tape before you screw it onto the air
connection (2).
The air sander has to be provided with lubricating oil during operation.
Before each use add oil through the air fitting or use an oil-fog
lubricator. Also pay attention to the chapter “Lubrication”.
1. Select the desired sanding tool and attach it on the drive shaft resp.
insert it into the drill chuck.
2. Connect the quick coupling adaptor of the air sander to the
compressor. Switch on the compressor and setup a pressure of 6 bar.
3. Use the speed controller (1) to steplessly control the air supply for the
air sander. This way you setup the max. possible rotation speed of the
sander that can be obtained when you fully press down the trigger.
4. Press down the trigger (3) to start the air supply and to operate the unit.
The trigger is also used to control the rotation speed. The deeper the
trigger is pressed, the faster the unit runs.
5. Release the trigger to interrupt the air supply and to stop the sander.
6. While working hold the unit firmly with your hands. Move the sander
evenly and as parallel as possible to the work piece to avoid ridges and
brush marks.
7. First disconnect the compressed air sander from the air supply when
exchanging the sanding tool, when not using the unit, after finished
working and when applying maintenance work. Press the trigger in
order to remove any remaining air from the compressed air sander.
Air Pressure and Air Volume
Operate the compressed air sander with a pressure of 6 bar (90 psi)
(when using higher pressure than the max. permitted pressure of 6.3
bar for operating the compressed air sander, self life of the tool will be
reduced drastically) using a compressor with an air suction capacity of
at least 150 l/min. The ideal capacity is provided by compressors with a
suction capacity of 200 – 300 l/min.
Only use air hoses with an inner diameter of at least 9 mm. When
setting up the air pressure, always keep in mind that the pressure will
