WARNING
Check that the system which fits the weight
to the rim is in optimum condition.
A weight which is not fitted properly or cor-
rectly may come off as the wheel rotates,
thus creating a potential danger.
The wheel can be locked in three ways in order
to make the weight application operation easier:
- By keeping the wheel in the centred position
for one second. The brake activates auto-
matically with a reduced braking force so
as to allow the operator to move the wheel
manually until the correct position for the
other weight's application is reached.
- By pressing the STOP button
the wheel is in one of the weight application
positions (maximum braking force); the wheel
is unlocked by pressing the stop
button 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
AUTOMATIC POSITION SEARCH section.

EASY ALU 1 and EASY ALU 2
programs
These programmes are used for maximum
precision 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.
However, bear in mind that it is always prefer-
able 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 Easy ALU 1 the balancing plane is approxim-
ately 15mm back (centre line of the weight)
from the contact point of the measuring head
with the rim (fig. 20).
In Easy Alu 2 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 one second the
