the tire be readjusted on the rim.
H0
The optimum minimization condition has been achieved
and cannot be improved.
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
rotating).
Option 1: Turn the tire over on the rim
(normal program)

Reading Un.8 appears
•
If weight minimization was carried out correctly
(according to the program cycle), after the check run
the machine automatically returns to the type of weight
B
positioning previously selected and indicates the
residual dynamic imbalance on the wheel.
•
Both weight minimization and balancing are accomplished.
Message E9
Message E9 means that at least one error occurred
during the minimization cycle. Press the STOP key
exit the minimization program and repeat minimization
if necessary.

(Fig.
Spin the wheel (START).
The machine performs the second measuring run
with the tire. After the measuring run three readings
are possible:
II - Un.7
Readjust the wheel according to the left direction
indicators and make a double mark
the left side of the tire exactly perpendicular to and
above the main shaft (A, Fig.
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 (1) to acquire the valve
position.
(Fig.
Spin the wheel (START) (check run).
Balance the wheel according to the readings.
Press the FINE key (3).
