desired (the corresponding balancing planes are highlighted on the rim shown on the
control panel).
- Set the nominal geometrical data of the wheel as described in the ENTERING THE
WHEEL DATA section. The machine will calculate new width and diameter values
using corrections on a statistical basis. If these values are outside the normally
accepted range stated in the TECHNICAL DATA section, the message "Alu Err" is
displayed.
- Perform a wheel spin, following the instructions provided for dynamic balancing.
Some slight residual imbalance may remain at the end of the spin test due to the
considerable difference in shape found in rims with the same nominal diameters. To
counter this, change the amount and position of the weights in accordance with the
"balance check" diagram (fig. 16) until an accurate balance status has been obtained.
FLASH OPT OPTIMISATION PROGRAM
This program has been made even simpler and faster than other types of OPT
program; in most cases, the results obtained can be compared with those of the
complete program described below, using fewer wheel spins and therefore speeding
up the procedure.
For guidance on this procedure, refer to the next section, bearing in mind that the flash
version of the program must not be accessed until a wheel spin has been performed.
The calculations made by this program are based on the imbalance values measured
during the last wheel spin performed, which must therefore refer to the wheel to be
balanced.
To recall this program proceed as follows:
- Press the

After the selection has been made, in all cases the machine indicates whether
execution of the program is advisable by displaying the message:
• "YES OPT" if it considers execution of the program is advisable;
• "NO OPT" in the opposite case.
