converted from inches to millimetres by selecting the

The arrow keys can be kept pressed for rapid increase or decrease of the values

- Carrying out a spin.
- Select the plane where the first balancing weight is to be applied.
- Rotate the wheel until the central element of the corresponding position indicator
is illuminated.
If the balancing weight is of the traditional clip type (inside plane in ALU 2P),
position the balancing weight at 12 o'clock. If, on the other hand, the weight is of
the adhesive type:
- centre it inside the cavity in the weight holder end of the measuring arm (a,
fig.19), with the backing paper of the adhesive strip facing up. Then remove the
backing paper.
- Move the sensor until the two reference lines (in yellow) in the window provided
on the screen.
- Rotate the end of the sensor until the weight adhesive strip is in position in
correspondence with the rim surface.
- Press the push button (c, fig.19) to eject the weight and make it stick to the rim.
- Return the sensor to the rest position.
- Repeat this process for the application of the second balancing weight.
- Carry out a test spin to check the accuracy of the balancing.
In order to be sure that the weight sticks to the rim the surface must be perfectly
clean. If necessary, clean the rim surface with a suitable detergent.
"Mobile planes" program (only available with ALU P programs)
This function is automatically activated when an ALU P program is selected.
It modifies the positions chosen for application of the adhesive weights in order
to allow the wheel to be perfectly balanced using commercially available adhesive
weights. This means that the balancing weights to be fitted to the rim will always be
multiples of five grams for car wheels and multiples of fifty grams for truck wheels.
This means there is no need to round the weights to be applied up or down or to
cut them to come closer to the real imbalance values. The result is a significant
improvement in balancing precision.
Normally the machine modifies the weight application positions on the basis of
criteria preset by the program.
(only available on demand with ALU P programs)
This program sub-divides the outside balancing weight into two combining
weights, located in a hidden position behind the two spokes on the aluminum rim.
- First select either the ALU 1P or the ALU 2P program; the selection is used making
