Alloy wheel balancing (ALU)
Self-adhesive weights are generally used to balance
alloy wheels and are applied differently than for
standard balancing (fig.22).
Several ALU balancing programmes are available,
specially designed for these types of rim.
ALU programmes can be selected as follows:
- press the
necessary to confirm the selection of the Alu
programme desired (the corresponding balancing
planes are highlighted on the rim shown on the
LCD display).
ALU 1P and ALU 2P programmes
These programmes are used for maximum preci-
sion balancing on light aluminium rims that require
the application of both weights on the same side
(inner) in relation to the rim disk.
This type of wheel balancer is particularly suit-
able 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.
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 accord-
ing 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

button as many times as
select balancing planes placed as far apart as pos-
sible; if the distance between the two planes is less
than 37 mm (1.5"), the "A 5" message is displayed.
- Move the end of the automatic measuring arm in
line with the plane selected for the application
of the inner weight. In Alu 1 P the centre of the
cavity where the adhesive weight is to be applied
must be used as reference (fig. 23).
- In Alu 2 P refer to the rim edge, since the inner
weight is of the traditional clip type (fig.16). Pay
maximum attention when the end of the arm is
being positioned in an area of the rim free of
discontinuity, so that the weight can be applied
in that position.
- Keep the arm in position. After one second the
machine emits an acoustic confirmation signal and
the weight icon on the LCD display stops blinking
to indicate that the distance and diameter values
have been acquired.
- Return the end of the automatic measuring arm
in line with the plane selected for the application
of the outer weight (fig.24), following the same
procedure previously indicated for the inner side.
- Keep the arm in position and wait for the acoustic
confirmation signal or until the weight icon stops
blinking.
- Return the measuring arm to the rest position.
Automatically the machine will setup in the ALUP
balancing programmes (FSP programme).
- Perform a spin
- at the end of the spin, if you want to change the
balancing programme set automatically by the
machine (FSP), select the
