CAUTION
Check that the system which fi ts the weight to the rim is in optimum condition.
A weight which is not fi tted properly or correctly 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 au-
tomatically 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;
- pressing the STOP
tions; 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 during installation of special centring ac-
cessories.

If the "RPA" (automatic position search) programme is active, at the end of each balanc-
ing 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 key

This function is described at length in the AUTOMATIC POSITION SEARCH section.
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.
This type of wheel balancer is particularly suitable for application of adhesive weights on
the rim, thanks to the forward position of the wheel in relation to the body, which allows
a large zone on the inside of the rim to be accessed freely.
To access these programmes:
Wheel data acquisition
Geometric data relating to the actual bal-
ancing 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
specifi c shape of the rim. However, bear in
mind that it is always preferable to select Centre of the weight holder cavity
