Figure 16. Conditions necessary for using
the Hidden weights programme
For alloy wheels, use the Hidden Weights
programme in conjunction with ALU 1P or
ALU 2P to conceal the external weight be-
hind two spokes for visual reasons.
To use this programme, proceed as follows:
1 Select either ALU 1 P or ALU 2 P before
starting.
2 Perform the wheel balancing procedure
as described in the chapter "ALU 1P, 2P
programmes", but without applying the
outer weight.
3 Press the
LED corresponding to the programme
illuminates
- Press
to enable the Hidden
Weights programme. If the user tries to
select this programme without previously
selecting an ALU P programme, the "A
26" message is displayed. If the wheel is
balanced on the outer side, the machine
displays the message shown in Fig. 16A.

4 To facilitate this procedure, mark the
Pe imbalance position on the tyre.
Move the wheel in the centred posi-
tion and mark the 12 o'clock position
with chalk.
5 Turn the wheel to the position in which
you wish to apply the first outer weight
(P1) and press
Use the 12 o'clock position as reference
in order to mark the exact position of
weight P1 relative to the imbalance Pe.
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. 16A for approximately
3 seconds to indicate that another
position must be chosen. If the angle
selected is less than 120°, the machine
displays the message shown in Fig. 16C,
prompting the user to continue to the
next step.
