BALANCING PROGRAMMES

Before starting a balancing operation, the
following 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 as
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
Each time it is pressed, the machine automat-
ically changes the type of balancing programme

Dynamic balancing (STANDARD)
This balancing mode is the most commonly
used one and the wheel balancer considers it
standard;
The mask relating to this program (fig. 19) is
displayed.
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
balancing 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 re-
sidual unbalance as large as 5-10 grams during
the verification phase, especially in the case
of large unbalances.
