Self-adhesive weights are generally used to balance alloy wheels and are applied differ-
ently than for standard balancing (Fig. 12).
Several ALU balancing programs are available, specially designed for these types of rim.
ALU programs can be selected as follows:
- Press the

desired (the corresponding balancing planes are highlighted on the rim shown on the
control panel).
These programmes are used for maximum precision balancing of light alloy rims that
require both weights to be applied on the same side (inner) in relation to the rim disk.
This type of wheel balancer is particularly suitable for application of adhesive weights on
the rim, thanks to the forward position of the wheel in relation to the body, which allows
a large zone on the inside of the rim to be accessed freely.
After selecting the desired ALU P programme, the wheel data must be acquired.
Wheel data acquisition
Geometric data relating to the actual balancing planes rather than the rated wheel
data (as in standard ALU programmes) have to be set. The balancing planes where the
adhesive weights are to be applied may be selected by the user according to the specific
shape of the rim. It should be remembered, however, that in order to reduce the quantity
of the weights to be applied it is better to select balancing planes placed as far apart
as possible; if the distance between the two planes is less than 37 mm (1.5"), the "A 5"
message is displayed.
In the version with digital sensor, proceed as follows:
