Balancing

Preliminary operations:
– If necessary, perform a compensation run (
– Check the wheel is clamped correctly (
– Select the Type of Vehicle (
– 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:
— Close the wheel guard.
or, if disabled the automatic measuring run,
— Close the wheel guard and press START.
— Starting from the completely lifted position, lower
the wheel guard, at medium speed without stops
or jerks even to the side.
Note: You must be very careful when lowering
the guard, as the machine simultaneously
detects the width of the rim on the outside
of the wheel.
The BALANCING screen is displayed (Fig. 5-11).
After measurement the balance weights can be fi tted
or a weight minimisation or optimisation run can be
carried out.
The specifi c icon with yellow profi le (1, Fig.5-11) and
the value of static unbalance with yellow background
inside the wheel (2, Fig.5-11), indicate that the
machine suggests to carry out a weight Optimisation
or Minimisation procedure.
The display shows the unbalance measured for
each correction plane and the rotation direction for
positioning.
