The machine performs the second measuring run
with the tire. After the measuring run three readings
are possible:
II - Un.7
Proceed with the UN program. It is recommended that
the tire be turned over on the rim.
Un.7 - II
Proceed with the UN program. It is recommended that
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
II - Un.7
Turn the tire over on the rim (the left display bars are
rotating).
Option 1:
Turn the tire over on the rim
(normal program)
•
Readjust the wheel according to the left direction
indicators and make a double mark
(
Fig. 37
)
on
the left side of the tire exactly perpendicular to and
above the main shaft
(
A
,
Fig. 38
)
.
•
Remove the wheel from the machine.
•
Turn the tire over on the rim and readjust until the
double mark coincides with the valve
(
B
,
Fig. 39
)
.
•
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.

.
•
Spin the wheel
(START
) (check run).
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
positioning previously selected and indicates the
residual dynamic imbalance on the wheel.
•
Balance the wheel according to the readings.
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
(
5
)
to
exit the minimization program and repeat minimization
if necessary.
Option 2:
Do not
turn the tire over on the rim
•
Press the
FINE
