components that are not in perfect condition (e.g. showing dents, abnormal wear, flange
unbalance, etc.).
Anyhow it is necessary to bear in mind that, if the cone is used to centre the wheel, satisfactory
balancing results cannot be achieved if the central hole of the wheel is out-of-round or incor-
rectly centred; Better results can be achieved by centring the wheel using the securing holes.
Bear in mind that any re-centring error made when the wheel is mounted on the car can be
removed only removed with an "on-the-vehicle balancing" of the wheel, using an on-the-
vehicle wheel balancer to complement the work of the wheel balancer.
Below is a list of faults that may occur and that the user can solve if the cause is found
among those indicated.
For any other malfunction or fault call in the technical support centre.

➥
The diameters and width values measured with the automatic
measuring devices do not match the rated values of the rims.
The sensors have not been positioned correctly during measurement.
➥ Bring the sensors to the position shown in the manual and follow the instructions
in the WHEEL DATA ENTRY section.
The external sensor has not been calibrated.
➥ Calibrate the ultrasonic sensor. See warning instructions at the end of the ULTRASONIC
WIDTH SENSOR CALIBRATION section
The automatic measuring devices are not working
The sensors were not in the rest position when switching on the machine and the Enter
