However, it is possible to readjust the tire relative to
the rim to achieve signifi cant weight minimization (i.e.:
smaller balance weights) without having an adverse
effect on silent running.
Depending on the readings, there are several
possibilities for proceeding with the program. These
possibilities are described below.
Reading
Turn the tire over on the rim (the left display bars are
5
rotating).
Option 1: Turn the tire over on the rim (normal program).

Reading OP.8 appears
•
If balancing optimization (silent running) has been
carried out correctly (according to the program cycle),
after the check run the machine automatically returns to
the type of weight positioning previously selected and
indicates the residual dynamic imbalance on the wheel.
•
Both optimization and balancing are accomplished.
Message E9
Message E9 means that at least one error occurred
during the optimization cycle. Press the STOP key
to exit the optimization program and repeat optimization
if necessary.
Option 2: Do not turn the tire over on the rim

The result is recalculated.
Reading

Option 3: Abort optimization
•
The imbalance on the wheel is shown on the readout.

II - OP.7 (Fig. 37)
Readjust the wheel according to the left direction
indicator and make a double mark on the left side
of the tire exactly perpendicular to and above the
main shaft.
Remove the wheel from the machine.
Turn the tire over on the rim and readjust until the
double mark coincides with the valve.
Clamp the wheel on the balancer and readjust it so
that the valve is exactly perpendicular to and above
the main shaft.
Press the ENTER key

(Fig.
Spin the wheel (START).
Balance the wheel according to the readings.
Press the FINE key (3).
OP.7 - II or H0 or H2 appears
To go to II - OP.7 (turning over the tire) press the
FINE key (3) again.
Press the STOP key (5) to exit the OP program and
return to the balancing program.
Balance the wheel according to the readings.
