Operation
Figure 5-73 OPTIMISATION "6"
(second measuring run with tyre)
 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.
 Confirm by pressing key 8.
The OPTIMISATION "7" screen may be displayed
(Fig. 5-75).
Alternately the indication H1 may appear
If H1 is displayed (Fig. 5-74), 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 wheel silent running conditions even below
the limit value (critical vehicle).
To continue optimisation:
 Continue as shown on screen OPTIMISATION OP
"7" (Fig. 5-75).
To abort optimisation
 To abort optimisation, press the STOP key, return
to the balancing program and balance the wheel
according to the instructions displayed
Figure 5-75 OPTIMISATION "7"
 On the tyre changer, turn the tyre with respect to
the rim until the valve is aligned with the mark made
on the tyre.
 Confirm by pressing key 8.
The OPTIMISATION "8" screen appears (Fig. 5-76).
