Setting V-belt tension left:

Loosen screw 2.

Tighten screw 2 again.
Setting V-belt tension right:
–
Turn the nuts 4 back so far that they do not lie onto the motor support plate.
The weight of the motor is now held by the V-belt.
–
Set the pressure spring 3 with the nuts 1 so that there is a clearance of 58 mm
between the nuts and the plate.
–
Screw the nuts 4 until they touch and then tighten one more turn.
This raises the support plate and slightly relieves the V-belt.
