Now proceed as follows:
1. Set the wheel's geometric data.
2. Spin the wheel by pressing the START
key.
To obtain the most accurate results, do
not apply any undue stress to the ma-
chine 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 of the rim corresponding to 12
o'clock.
7. Repeat the operations listed for the second side of the wheel.
8. Perform a test wheel spin to check the balancing accuracy.
If it is not satisfactory, modify the value and position of the weights previously applied.
Bear in mind that a counterweight positioning error of just a few degrees may lead to
a residual unbalance as large as 5-10 grams during the verification phase, especially in
the case of large unbalances.
CAUTION
Check that the system which fits the weight to the rim is in optimum condition.
A weight which is not fitted properly or correctly may come off as the wheel rotates,
thus creating a potential danger.
The wheel can be locked in three ways in order to make the weight application opera-
tion easier:
- by keeping the wheel in the centred position for one second. The brake activates au-
tomatically with a reduced braking force so as to allow the operator to move the wheel
manually until the correct position for the other weight's application is reached;
- pressing the STOP
positions; the wheel is unlocked by pressing the Stop button again, by performing a
spin or after about 30 seconds.
The shaft locking system can also be useful during installation of special centring accessories.
If the STOP key
even if it is not completed.
If the "RPA" (automatic position search) programme is active, at the end of each balanc-
ing spin the machine stops the wheel in the position for application of the weight on the
outer side; if it is equal to zero, the wheel is stopped in the position for application on
the inner side.
