— Rotate the wheel into marking position following the
arrows.
— In this position mark the tyre, on the outer side of
the wheel, precisely above the chuck.
— Confi rm by pressing the key 26.
The OPTIMISATION "OP.7" may be displayed (Fig.
5-49).
Alternately the indication H1 may appear
If H1 is displayed (Fig. 5-48), further optimisation is not
recommended since the measurement values which
activate the optimisation recommendation are below
the pre-set limit value.
However, it is possible to continue optimisation so as
to improve silent running conditions even for values
below the threshold limit (critical vehicle).
To continue optimisation:
— Continue as shown on screen OPTIMISATION OP
"OP.7" (Fig. 5-49).
To abort optimisation
— Press the STOP key to return to the balancing
program and balance the wheel according to the
readings 5.8.
