weight P2 relative to the imbalance Pe.
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. 16D for
approximately 3 seconds to indicate
that the procedure described in step
7 must be repeated correctly. If the
angle selected is less than 120°, the
machine immediately displays the
value of weight P2. The LED
remains on to indicate that the "Hidden
Weight" programme is active.

9 Manually turn the wheel, the two
unbalance values calculated are dis-
played in alternation on the display
regarding the outer side as the angular
position of the wheel changes.
10 Apply each of the two balancing
weights as described in the chapter
"ALU 1P, 2P Programmes".
11 Once the Hidden Weights programme
procedure is complete, you may
continue working with any other pro-
gramme.
The HIDDEN WEIGHT function is combined
with the SHIFT PLANES function to allow
balancing weights which are multiples of 5
grams to be used.
Standard ALU Programmes
(ALU 1, 2, 3, 4, 5)
The standard ALU programmes allow for
66
the various modes of application of the
weights (Fig. 12) and supply correct unbal-
ance values maintaining the settings of the
rated geometric alloy wheel data.
- Press the
until the LED corresponding to the ALU
programme illuminates.
- Press the
sary to confirm selection of the desired Alu
programme (the corresponding balancing
planes are highlighted on the rim shown
on the display).
- Set the rated geometric data.
If the values of the diameter and of the
distance between the balancing planes,
recalculated on a statistical basis starting
from the rated geometric data of the wheel,
exceed the normally accepted interval
stated in the TECHNICAL DATA section,
the "A Alu" message is displayed.
- Proceed as described for dynamic balanc-
ing.
- For the application of the balancing
weights, refer to the paragraph "SELEC-
TION OF ADHESIVE WEIGHTS APPLICA-
TION POSITION".
Some slight residual unbalances may
remain at the end of the test spin due to
the considerable difference in shape that
may be found on rims having the same
rated dimensions. Therefore modify the
value and position the previously applied
weights for accurate wheel balancing.
Motorcycle Wheel balancing
Motorcycle wheels can be balanced in:
- Dynamic mode; when the wheel width is
such (over 3 inches) to generate significant
unbalance components which cannot
be eliminated with static balancing (the
recommended procedure).
- Dynamic mode for alloy rims; a pro-
