1. SWITCHING ON THE MACHINE
Connect the power supply cable (A, Fig.10) sup-
plied 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.10).
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 ac-
tive 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);
- active 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 pro-
grammes available.
2. BALANCING PROGRAMME SELECTION
Before starting a balancing operation, the following steps must be followed:
- fit the wheel on the hub using the most suitable flange;
- lock the wheel so that no movement is possible during the wheel spin and braking
phases;
- remove any counterweight, pebble, dirt or other foreign body;
- set the wheel's geometric data correctly.
At start-up, by default, the wheel balancer executes the dynamic programme (dyn) which
uses clip weights on both sides.
The various balancing programmes can be recalled by simply selecting the keys
that represent the type of weight according to the rim and professional experi-
ence, both for the inner side as well as for the outer side.
The following balancing programmes are available:
