Fig. 24 Hidden Weights: procedure error
If there is an unbalance on the outer side (Pe) the
machine will display the graphic that indicates
the selection of the P1 weight position.
Press at any time to exit the "Hidden Weights"
programme
4. To make work easier mark the position of the
unbalance Pe on the tyre. To do this, move the
wheel to a centred position and make a chalk
mark at 6 o'clock if the "LASER" configuration is
active and at 12 o'clock if the "H12" or "CLIP"
configuration is active.
5. Turn the wheel to the position in which you
wish to apply the first outer weight (P1) and
press to confirm.
To select the exact position of the weight P1
relative to the Pe unbalance, use 6 o'clock as
the reference if the "LASER" configuration is
active and 12 o'clock if the "H12" or "CLIP"
configuration is active.
The angle between P1 and Pe must be less than
120°.
6. If the angle selected is greater than 120°, the
machine displays the message shown in Fig. 24b
for approximately 3 seconds to indicate that
another position must be chosen. If, however,
the angle selected is less than 120°, the ma-
chine displays a graph indicating the selected
position for the weight P2, allowing the process
to continue to the next step
7. Turn the wheel to the position in which you
wish to apply the second outer weight (P2)
and press to confirm.
To select the exact position of the weight P2
with respect to the Pe unbalance, use 6 o'clock
as the reference if the "LASER" configuration
is active and 12 o'clock if the "H12" or "CLIP"
configuration is active.
The angle between P1 and P2 must be less than
120° and must include the outer weight Pe.
8. If the angle selected is greater than 120°, the
machine displays Fig. 24b for approx. 3 seconds
indicating that the procedure of step 7 must

be repeated correctly. If the angle selected
is less than 120°, the machine immediately
displays the value of the two outer weights
P1 and P2 on the screen.
9. Move the wheel to a centred position (P1 or P2).
10. The brake intervenes automatically in the
centred position, then apply the balancing
weight indicated on the monitor as described
in the chapter "EASY ALU1, EASY ALU2 Pro-
grammes".
11. Move the wheel to a centred position (P1
or P2).
12. Repeat the operations in step 10.
13. Once the Hidden Weights programme pro-
cedure is complete, you may continue working
with any other programme.
Standard ALU Programmes
(ALU 1, 2, 3, 4, 5)
Standard ALU programmes take into account
the different possibilities of weight applica-
tion (fig. 25)
and provide correct unbalance values while
maintaining the rated geometric data setting
of the alloy wheel.
ALU 1 balancing programme:
Calculates statistically the balancing weights
to be applied on the inner part of the rim, as
illustrated by the relevant icon.
