Operation
according to the direction indicator and make a
chalk mark
(
Fig. 5-36
)
on the right side of the tyre
exactly perpendicular to and above the main shaft.
•
Readjust the tyre on the rim so that the mark
coincides with the valve (use the tyre changer
Fig.
5-37
).
•
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.

The machine performs the second measuring run
with the tyre. After the measuring run three readings
are possible:
II - Un.7
Proceed with the UN program. It is recommended that
the tyre be turned over on the rim.
Un.7 - II
Proceed with the UN program. It is recommended that
the tyre be readjusted on the rim.
H0
The optimum minimisation 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 tyre over on the rim (the left display bars are
rotating).
Option 1:
Turn the tyre over on the rim
(normal program)
•
Readjust the wheel according to the left direction
indicator and make a double mark on the left side
of the tyre exactly perpendicular to and above the
main shaft
(
Fig. 5-36
)
.
•
Remove the wheel from the machine.
•
Turn the tyre over on the rim and readjust until the
double mark coincides with the valve
(
Fig. 5-37
)
.
•
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 (

) to acquire the valve
position.

•
Spinn the wheel
(START
) (check run).
If weight minimisation 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.
