Operation

QSelecting the correct rotational speed and sanding belt

You can select the belt speed using the belt speed adjuster wheel 1 even whilst the sander is running. The optimum belt speed depends on the workpiece and the workpiece material. Always confirm the best speed by carrying out a small test. The follow- ing table lists some recommended values to help you determine the optimum speed.

QUsing the sander in a fixed mounting

The fixed mounting kit allows you to use the device for sanding vertically or horizontally by fastening it on to a flat stable surface (e.g. workbench).

Sanding horizontally (see Fig. E):

jInsert the two spacer plates 15 e into the holes provided for them on the supporting surface of the mounting frame 12. The tapers must narrow towards the outside (see Fig.).
