NOTE
If the width measurement is highlighted in
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
procedure 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 Configura-
tion 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 differ-
ent 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).
