Application of adhesive
balancing weights
- Select the plane where the balancing weight
is to be applied.
- Turn the wheel until the central part of the
corresponding position indicator lights up
or press the centre of the round indicator to
start the automatic position search.
- The internal laser pointer automatically comes
out indicating the exact position for applying
the adhesive weight.
- Apply the adhesive weight as indicated in
the figure.

The rim surface must be perfectly clean to make
the weight stick efficiently to the rim. If neces-
sary, clean the surface using suitable cleansing
products.
Note: the adhesive weights outside the rim folder
in the ALU3 and ALU4 balancing programmes
should be applied manually in the 12 o' clock
position.
"Shift Planes" programme
(available only with ALU1 and
ALU2 programmes)
This function is automatically enabled when an
ALU1 or ALU2 programme is selected. It modi-
fies the selected positions for the application of
adhesive weights, so as to ensure perfect balanc-
60
ing of the wheel using commercially available
adhesive weights (i.e. multiples of five grammes).
The accuracy of the machine is thereby improved,
avoiding rounding-off or cutting the weights to be
applied to come closer to the actual unbalance
values. For this reason, the secondary control
key is not enabled
The modified positions, where the adhesive
weights are to be applied, are identified by the
user according to the information given by the
wheel balancer.
"Hidden Weight" programme
(available only with ALU1 and
The Hidden Weight programme should be used
on alloy rims in conjunction only with the ALU1
or ALU2 programmes when the external weight
needs to be hidden behind two spokes for
aesthetic reasons. This programme subdivides
the outer balancing weight (Pe) into two equal
weights (P1 and P2) placed in concealed positions
behind two spokes of the alloy rim.

The two weights must be placed within an arc of
120°, including the Pe weight.
To start this programme, proceed as indicated
below:
- Select one of the balancing programmes, ALU1
or ALU2.
- Perform a spin.
- At the end of the spin, if there is an unbalance
on the outer side (Pe), the machine will display
.
ALU2 programmes)
