unlocked by pressing the stop
again, by performing a spin or after about 30
seconds.
The shaft locking system can also be useful dur-
ing installation of special centring accessories.
If the STOP
the wheel is spinning, the spin is interrupted
even if it is not completed.
If the "RPA" (automatic position search) pro-
gramme is active, at the end of each balancing
spin the machine stops the wheel in the position
for application of the weight on the inner side;
if it is equal to zero, the wheel is stopped in
the position for application on the outer side.
Pressing the START
guard raised, automatic search for the second
side position is activated.
This function is described at length in the AUTO-
MATIC POSITION SEARCH section.
ALU 1P and ALU 2P programs
These programmes are used for maximum pre-
cision balancing of light alloy rims that require
both weights to be applied on the same side
(inner) in relation to the rim disk.
Wheel data acquisition
Geometric data relating to the actual balancing
planes rather than the rated wheel data (as in
standard ALU programmes) have to be set. The
balancing planes where the adhesive weights
are to be applied may be selected by the user
according to the specific shape of the rim. How-
ever, bear in mind that it is always preferable to
select balancing planes as far apart as possible
in order to reduce the quantity of the weight
to be applied; if the distance between the two
planes is less than 37 mm (1.5"), the A 5 message
is displayed.
- Move the end of the automatic internal meas-
uring arm in line with the plane selected for
the application of the inner weight.
In ALU 1P the balancing plane is approximately
15mm back (centre line of the weight) from the
contact point of the measuring head with the
rim (fig. 20).

In Alu 2 P refer to the rim edge, since the inner
weight is of the traditional clip type (fig. 14).
Pay maximum attention when the end of the arm
is being positioned in an area of the rim free of
discontinuity, so that the weight can be applied
in that position.
- Keep the arm in position. After
machine emits an acoustic confirmation signal to
indicate that the distance and diameter values
have been acquired.
- Return the end of the automatic measuring arm
in line with the plane selected for the applica-
tion of the outer weight (fig. 21), following the
same procedure previously indicated for the
inner side.
