OPTIMISATION “
OP.4
”
(fi rst measuring run of tyre/rim assembly)
—
Clamp the wheel on the balancer.
—
Readjust the wheel such that the valve is exactly
perpendicular to and above the main shaft.
—
Enter the valve position by pressing menu key
F1
.
The OPTIMISATION “OP.5” screen (
Fig. 5-40
) is displayed.

START is signalled on the screen.
—
Press the
START
key.
A measuring run is performed.
The OPTIMISATION “OP.6” screen (

) is displayed.
5.10.5 Continue minimisation and
optimisation
Fig. 5-41
OPTIMISATION “
OP.6
”
(second measuring run of tyre/rim assembly)
From this screen weight minimisation is carried out in the
same way as optimisation.
—
Rotate the wheel into marking position following the
arrows.
—
Provide a
single mark
on the tyre outer side exactly
perpendicular to and above the main shaft.
—
Confi rm by pressing menu key
F1
The OPTIMISATION “OP.7” screen (
Fig. 5-43
) is displayed.
Reading H 1
If
H 1
(
Fig. 5-42
)
is read out further optimisation is not
recommended. In this case the measured data does not
exceed the limit for recommendation of the optimisation
program. However, it is possible to continue optimisation so
as to improve wheel running conditions even below the limit
value (critical vehicle).
To continue optimisation:
—
Continue as shown on screen OPTIMISATION “OP.7”
(
Fig. 5-43
).
To abort optimisation:
—
Press the
STOP
key to return to the balancing program
and balance the wheel according to the readings.
