3.4 V-belt Tension

Setting V-belt tension left:

–

Loosen screw 2.

–

Turn the nuts 4 back so far that they do not lie onto the motor support plate.

The motor's own weight sets the correct tension for the left V-belt (at the right in the

picture).

–

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.
