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 satisfactory, modify the value and position of the weights previously ap-
plied.
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.
WARNING
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 acces-
sories.

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
inner side; if it is equal to zero, the wheel is stopped in the position for application on
the outer side.
