Selecting 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.
