4.7 Revolution changer
The potentiometer can be used to infinitely adjust the revolutions of the working spindle from 150-2300
rpm (2nd setting = preset at the factory).
If the lower revolutions of 30-490 rpm (1st setting) are required, the drive belt must be applied. To do
this, proceed as follows:
1. Open the gear cover hood by undoing the safety screw with the supplied special key
2. Undo clamping nut (1) and this loosen the drive belt
3. Turn the nut (2) clockwise in such a way that the drive belt can be apportioned
4. To tension the drive belt this process is to be completed reversed
5. Close the drive cover hood again and secure with the safety screw.
