performed by displaying the E 1 error message.
Calibrate as follows:
- select the sensitivity calibration icon in the
configuration programme menu;
- Fit a wheel of average dimensions (diameter
no less than 14") and preferably with a small
imbalance only on the wheel balancer.
- perform a spin;
- At the end of the spin, fix the calibration
weight supplied with the machine on the
shaft assembly bell as indicated in figure 22.
- perform a second spin;
- At the end of the spin, change the position of
the calibration weight on the shaft assembly
bell as indicated in figure 23
- Perform a third spin. This last calibration phase
70
consists of three consecutive spins executed
automatically.
If the calibration has been successful, a permis-
sion acoustic signal goes off at the end of the
spin; otherwise, the E 2 message is temporarily
displayed.
Notes:
- Once the procedure is finished, remove the
calibration weight.
- Press the key to interrupt the calibration pro-
cedure at any time.
- This calibration is valid for any kind of wheel.

consult them.
6.5. C emergency system release (wheel
clamping device)
This programme allows, in case of emergency,
the device C to be opened when it is NOT
