CHECK FOR CORRECT FUNCTIONING OF
BALANCING ACCESSORIES
Checking balancing accessories allows the operator to make sure that wear has not altered
the mechanical specifications of flanges, cones, etc. beyond the specified limits.
A perfectly balanced wheel, which has been disassembled and reassembled in a different
position, should not show an unbalance value greater than 10 grams.
When a higher unbalance is found, check all the accessories carefully and replace the components
that are not in perfect condition (e.g. showing dents, abnormal wear, flange unbalance, etc.).
Anyhow it is necessary to bear in mind that, if the cone is used to centre the wheel, satisfactory
balancing results cannot be achieved if the central hole of the wheel is out-of-round or incor-
rectly centred; Better results can be achieved by centring the wheel using the securing holes.
Bear in mind that any re-centring error made when the wheel is mounted on the car can be
removed only removed with an "on-the-vehicle balancing" of the wheel, using an on-the-ve-
hicle wheel balancer to complement the work of the wheel balancer.
Below is a list of faults that may occur and that the user can solve if the cause is found among
those indicated.
For any other malfunction or fault call in the technical support centre.
No power at the socket.
Check the mains voltage is present.
➥
Check the electrical power circuit in the workshop.
➥
The machine plug is defective.
Check that the plug is undamaged.
➥
One of the FU1-FU2 fuses of the rear electrical panel has blown
Replace the blown fuse.
➥
The diameter measured by the automatic measuring sensor does
not match the specification of the wheel.
The sensor was not positioned correctly when measuring.
Bring the sensor to the position shown in the manual and follow the instructions in
➥
the WHEEL DATA ENTRY section.
The automatic measuring sensor does not work
The sensor was not in the rest position at switch-on (A 10) and the
pressed to enter the wheel geometric data with the keypad, disabling control of the au-
tomatic sensor.
Return the sensor to the correct position.
