2. Fit a wheel of average or larger dimensions
preferably with only small unbalance on the
wheel balancer;
3. activate spinning;
4. At the end of the spin, fix the calibration
weight supplied with the machine on the
swinging unit bell as indicated in figure 27;
5. spin again;

7. spin a third time;
At the end of the fourth calibration spin, the ma-
chine will automatically perform two subsequent
spins at different wheel rotational speeds that
are lower than the previous spins.
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:
