SWITCHING ON THE
MACHINE
Connect the power supply cable (A, Fig. 9b)
supplied with the machine from the external
electrical panel located on the rear side of
the wheel balancer body to the mains.
Switch on the machine using the switch on
the rear side of the body (B, Fig. 9b).

The wheel balancer performs a checking
test (all the LEDs illuminate), and if no
faults are detected, a beeper sounds and
the cycle status initially active is displayed,
as follows:
- active balancing mode: dynamic (DYN);
values displayed : 000 000;
- grams displayed in units of 5 (or 1/4 of an
ounce);
- sensor rounding-off (version with digital
sensor);
- default geometric values: width = 5.5",
diameter = 14", distance = 150 mm.
Now the operator can set the data of the
wheel to be balanced or select one of the
programmes available.

The machine allows for the diameter and
distance values to be entered automati-
cally; the width value can be entered using
the keypad.
- Move the automatic measuring arm (A,
Fig. 7) so it comes into contact with the
inner side of the rim as shown in Fig.
10/10a.
Take great care to position the arm cor-
rectly so as to ensure accurate data
reading.
- Keep the arm in contact with the rim until
the machine has acquired the wheel's
diameter and distance values. The geo-
metric data are displayed in sequence:
• d
distance value;
• di
diameter value.
When a geometric value is displayed, the
corresponding LED illuminates on the
display panel.
- Check the values measured and then
return the arm to the rest position. The
machine now presets for WIDTH meas-
