"Hidden Weight" programme
(available only with ALU1 and
ALU2 programmes)
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.
α ≤ 120°
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
the Hidden Weight button
the main screen.
-
Press this button;
the internal laser pointer will automatically
move onto the outer plane (Pe).
-
Turn the wheel clockwise until you reach the
point where you want to apply the first outer
weight (P1) and align the laser point with a
spoke.

Turn the wheel anticlockwise until you reach
the point where you want to apply the second
outer weight (P2) and align the laser point
with the second spoke.

button on the monitor to confirm the opera-
tion;
-
When the procedure is completed, the unbal-
ance image is displayed on the screen includ-
ing two position indicators for the outer side.
The unbalance value displayed for this side
refers to the indicator in the centred position
condition.
Each of the two balancing weights is applied as
described in the "Balancing weight application"
section.
The Hidden weight function is combined with the
Shift planes function to allow balancing weights
18
which are multiples of 5 grams to be used.
You can quit the Hidden weight procedure at
any time by simply pressing the Exit button
The Hidden weight function can be disabled by
pressing the Hidden Weight.
Hidden Weight Programme is enabled even
when the operator inserts the wheel dimen-
sions manually (possible anomaly of one or
both lasers).
