7.2. Centrifugal force adjustment with swivel
unbalance discs

From size HV 12/4-60 (exception HV 30/2 and HV 55) the centrifugal force is
adjusted by turning the two outer unbalance disks.

The percentage centrifugal force can be either:

a) read off the scale on the shaft. One division corresponds to 10%.

or

b) read off the back (fixed) unbalance on the etched scale. One division
corresponds to 5%

The setting must be symmetrical (see illustration on page 20).
