Balancing
Preliminary operations:
– If necessary, perform a compensation run (C4
7.1.1).
– Check the wheel is clamped correctly (
– Read the rim dimension parameters (
If more than one wheel of the same type needs to be
balanced (the same nominal dimensions) the data need
only be set for the fi rst wheel. The selections stay set
until other new data is set or the machine is switched off.

Measuring imbalance
Having completed the preliminary operations, a
Measuring run can be launched:

— Lower the wheel guard from the fully raised position.
Pull the guard smoothly at medium speed, without
stops or jerking even to the side.
Note:
You must be very careful when lowering
the guard, as the machine simultaneously
