This procedure reduces the possible vibrations still present in running vehicles after an
accurate balancing. based on our experiences, the programme can be recalled every time
it is convenient to minimise the running noise produced by the vibrations mentioned above.
The machine also indicates whether or not it is necessary to carry out the procedure by
displaying the following icon
The calculations performed by this programme are based on the unbalance values meas-
ured during the last spin performed which must therefore refer to the wheel being serviced.
Proceed as follows to recall this programme:
- Select the OPT Flash icon
OPT STEP 1
1. take the valve to 12 o'clock;
2. press Enter
OPT STEP 2
3. turn the wheel until the valve gets to 6 o'clock position (the bottom arrow turns from
red to green);
4. make a chalk mark on the tyre external side at 12 o'clock;
5. confirm you marked the tyre by selecting Enter
6. remove the wheel from the wheel balancer;
7. turn the tyre on the rim until the mark made matches the valve (180º rotation);
8. refit the wheel on the wheel balancer and confirm the operation described in points 6
and 7 by selecting enter
Then, following the new indications on the monitor:
9. turn the wheel until the valve gets to 12 o'clock position:
10. press the Enter button
11. perform a spin.
Now, the real unbalance values of the wheel thus mounted on the wheel balancer are
displayed. Take the wheel to the position shown on the monitor. The foreseen unbalances
are displayed by performing the matching and the proportional improvement which can be
obtained if the user decides to continue the optimisation procedure.
In case optimising is insufficient, or significant improvements cannot be obtained, select
