Several ALU balancing programmes are
available, specially designed for these
types of rim.
ALU programmes can be selected as fol-
lows:
- Press the
the LED corresponding to the ALU pro-
gramme illuminates.
- Press the
essary to confirm selection of the Alu
programme desired (the corresponding
balancing planes are highlighted on the
rim shown on the control panel).
ALU 1P and ALU 2P programmes
These programmes are used for maximum
precision balancing on light aluminium
rims that require the application of both
weights on the same side (inner) in rela-
tion 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 pro-
gramme, the wheel parameters must be
acquired.
Wheel data acquisition
Geometric data relating to the actual bal-
ancing 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

keys until
key as often as nec-
is displayed.
With the version with automatic sensor,
proceed as follows:
- bring the end of the automatic measuring
arm level with the selected plane for the ap-
plication of the inner weight. In Alu 1 P, the
centre of the peg at the end section of the
arm is used as the reference for the centre
line of the weight (Fig. 13).
- In Alu 2 P, use the rim edge as reference,
as a conventional clip weight is used
(Fig.10).
Pay maximum attention when the end
of the arm is being placed 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 two
seconds the machine emits an acoustic
confirmation signal to indicate that the
distance and diameter values have been
acquired.
- bring the end of the automatic measur-
ing arm level with selected plane for
applying the external weight (Fig. 13a),
as described for the inner side.
