the other weight's application is reached.
- By pressing the Stop button
the wheel is in one of the weight application
positions and the brake is not on. The wheel is
unlocked by pressing the same button again,
performing a spin or after 50 seconds.
The shaft locking system can also be useful dur-

to zero, the wheel is stopped in the inner side
weight application position.
By selecting the central part of one of the unbal-
ance position indicators, an automatic centred
position search starts.
Balancing programmes for alloy
rims
ALU 1 - 2 - 3 - 4 - 5
These programmes are used for maximum preci-
sion balancing of light alloy rims.
This type of wheel balancer is particularly suit-
able 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 one of these programmes, select at
least one adhesive weight.

Note: the balancing planes where the adhesive
weights are to be applied may be selected by the

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
