if it is RED
NOT read. To remedy this situation, move the wheel
slightly until the sensor status changes.
If the sensor configuration does NOT change by
moving the wheel (or using a different wheel)
enter the dimensions manually and contact
technical support.
Note: 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. It
should be remembered, however, that in order to
reduce the quantity of the weight that is to be ap-
plied it is preferable to select balancing planes that
are as far apart as possible: if the distance between
the two planes is less than 37 mm (1.5"), the A 64
message is displayed.
Dynamic balancing (Dynamic)
This balancing mode is the most commonly used one.
If a different balancing programme is running, the
programme must be set by selecting the correct icons.
Now proceed as follows:
Press the Dimensions button
-
enable automatic dimension measurement. The
button remains pressed
- Spin the wheel by lowering the guard.
To ensure accurate results, do not apply undue stress
to the machine during the spin and do not interfere
with laser sensor reading.
- Select the first side to be balanced.
- Rotate the wheel until the central element of the
corresponding position indicator lights up.
- Apply the indicated balancing weight to the 12
o'clock position on the rim.
- Repeat the operations listed for the second side
of the wheel.
- Perform a test spin to check balancing accuracy.
If it is not considered satisfactory, change the
value and position of the previously applied
weights, according to the data indicated in the
balancing control diagram (Fig. 16).

this means that the laser does
.
Bear in mind that a counterweight positioning error
of just a few degrees may lead to a residual unbalance
as large as 5-10 grams during the verification phase,
especially in the case of large unbalances.
WARNING
Check that the system which fits the weight to the
rim is in optimum condition.
A weight which is not fitted 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
approximately one second. The brake activates
automatically 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
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 during
installation of special centring accessories.
If the Stop button
the wheel is rotating, the spin will be prematurely
interrupted.
