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 behind 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

The angle between P1 and Pe must be
less than 120°.
6 If the angle selected is greater than 120°,
