BALANCING
PROGRAMMES
Before starting a balancing operation, the follow-
ing steps must be followed:
- Mount the wheel on the hub using the most
suitable centring system.
- Make sure that the wheel is locked correctly
to the shaft so that no displacement can occur
during the spin and braking phases.
- Remove any counterweight, pebble, dirt or
other foreign body.
- Set the wheel's geometric data correctly
indicated in the "WHEEL DATA ENTRY" chapter..
The balancing programmes are grouped within
the balancing programmes icon in the main
working screen.
Select the icon
Kis knob or
the keypad Enter button.
Each time it is pressed, the machine automati-
cally changes the type of balancing programme
(as shown on the graphic on the video) in the
following sequence:

- ALU1
- ALU2

This balancing mode is the most commonly used
one and the wheel balancer considers it standard;

as
Now proceed as follows:
1. set the wheel's geometric data as indicated
in the " WHEEL DATA ENTRY" chapter.
2. Spin the wheel by lowering the guard.
To obtain the most accurate results, do not
apply any undue stress to the machine during
wheel spin.
3. Wait for the wheel to stop automatically and
for the calculated unbalance values to be
displayed.
4. Select the first side to be balanced.
5. Turn the wheel until the central element of
the corresponding position indicator lights
up.
6. Apply the indicated balancing weight in
the position on the rim corresponding to 12
o'clock.
7. Repeat the operations listed above for the
second side of the wheel.
8. Perform a test wheel spin to check the bal-
ancing accuracy.
If it is not considered satisfactory, change the
value and position of the previously applied
weights.
Bear in mind that a counterweight positioning
error of just a few degrees may lead to a resid-
ual unbalance as large as 5-10 grams during the
verification phase, especially in the case of large
unbalances.
