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 speci-
fied limits.
A perfectly balanced wheel, which has been
disassembled and reassembled in a differ-
ent 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 incorrectly 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-vehicle wheel balancer
to complement the work of the wheel
balancer.

TROUBLESHOOTING

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.
The machine does not switch on
(the displays remain switched off)
No power at the socket.
- Check that mains power is on.
- Check that the workshop electrical
system is working correctly.
The machine plug is defective.
Check if the plug is working properly
-
and replace if necessary.
One of the FU1-FU2 fuses of the rear
electrical panel has blown
- Replace the blown fuse.
The diameters and width
values measured with the
automatic measuring devices
do not match the rated values
of the rims.
The sensors have not been positioned
correctly during measurement.
- Bring the sensors to the position
shown in the manual and follow the
instructions in the WHEEL DATA
ENTRY section.
The external sensor has not been
calibrated.
- Perform the sensor calibration proce-
dure. See warning instructions at the
end of the SENSOR CALIBRATION
section.
The automatic measuring
devices are not working
The sensor was not in the rest position
at switch-on (A 10) and the
key has been pressed to enter the wheel
