CCC - CCC
Unbalance values greater than 999 grams.
CHECK FOR CORRECT
FUNCTIONING OF
BALANCING ACCESSORIES
Checking balancing accessories allows the opera-
tor 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, satisfac-
tory 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-vehicle
wheel balancer to complement the work of the
wheel balancer.

MAINTENANCE
WARNING
The manufacturer declines all responsibility for
claims resulting from the use of non-original
spare parts or accessories.
WARNING
Unplug the machine from the power supply
and make sure that all moving parts have been
locked before performing any adjustment or
maintenance operation.
Do not remove or modify any part of the machine
(except for service interventions).
CAUTION
Keep the work area clean.
Never use compressed air and/or jets of water
to remove dirt or residues from the machine.
Take all possible measures to prevent dust
from building up or raising during cleaning
operations.
Keep the wheel balancer shaft, the securing
ring nut, the centring cones and flange clean.
These components can be cleaned using a brush
previously dripped in environmentally friendly
solvents.
Handle cones and flanges carefully so as to avoid
accidental dropping and subsequent damage
that would affect centring accuracy.
After use, store cones and flanges in a place where
they are suitably protected from dust and dirt.
If necessary, use ethyl alcohol to clean the dis-
play panel.
Perform the calibration procedure at least once
every six months.
INFORMATION
REGARDING MACHINE
DEMOLITION
If the machine is to be scrapped, remove all
electrical, electronic, plastic and metal parts
and dispose of them separately in accordance
with current provisions as prescribed by law.
