red, it means that one of the automatic control
parameters has not been met and it is therefore
advisable to check the dimension. Using the touch
screen select, if necessary, the feedback window
and manually enter the nominal width of the rim,
press enter and exit the manual entry mode.
NOTE
If the laser sensors fail to operate, the geometric
data can be entered manually by following the pro-
cedure indicated in the "Manual wheel data entry"
section. This function is present in the Utility and
Configuration programmes.
NOTE
The laser sensors may not measure the rim dimensions
correctly on particularly reflective surfaces. In this
case enter the geometric data manually following
the procedure described in the paragraph "Manual
wheel data entry", which is a function present in the
Utility and Configuration programmes.
CAUTION
bear in mind that the nominal wheel diameter
(e.g. 14") refers to the planes on which the
tyre beads rest which are obviously inside the
rim. On the other hand, the data measured refer
to external planes, so they will be lower than
the rated values because of the thickness of
the rim. The correction value therefore refers
to an average thickness of the rim. This means
that the data measured on wheels with different
thicknesses may vary slightly (2 or 3 tenths of
an inch maximum) from the rated values. This is
not a lack of accuracy of the measuring devices,
but reflects reality.
WARNING
Do not operate the machine without the guard and/
or if the safety device has been tampered with.
WARNING
Never raise the guard before the wheel has come
to a stop.

WARNING
If the wheel keeps spinning permanently due to a
fault on the machine, switch off the machine using
the main switch or disconnect the plug from the
power supply board (emergency stop) and wait
until the wheel stops before raising the guard.
- Wait for the wheel to stop automatically and the
image shown in figure 14 to be displayed showing
the automatically recognised edge and indicated by
the laser point of the internal sensor on the rim.
If the selected balancing programme requires the
application of a spring weight on the inner side,
the laser point must correspond with the rim edge
(figure 15).
Position 1 spring weight
If the selected balancing programme requires the
application of an adhesive weight on the inner side,
the laser point must correspond with the application
plane of the adhesive weight. Please remember that
the laser point indicates the centre of the weight
(figure 15a).
Position 2 adhesive weight
