14.3.4 ALU-S procedure
The ALU-S balancing is a procedure that offsets the
wheel vibrations using 2 weights on different planes.
Adhesive weights are used inside the rim, and usually
on alloy rims.
To launch a ALU-S measurement, proceed as follows:
- Make sure there are no stones and/or mud on the
wheel. Remove any counterweights. Fit the wheel and
make sure it is properly fastened (see Chap. 12.0).
- Determine the wheel dimensions using the specific
gauge rod (see Par. 14.1.1).
- Close the protection guard to perform the automatic
wheel spin.
In just a few seconds, the wheel runs at normal speed
and the display screens D1-D2 show wheel rotation.
After the spin, the wheel stops automatically, taking
into account the measured unbalance so that the fitting
position of the outer weight is around at “12 o' clock”.
Open the protection guard.
Display screens D1-D2 show the weight required to
correct the unbalance. The nearby LEDs show the
direction the wheel has to be moved into to fit the
weights (Fig. 31).

Once the unbalance value of the inner and outer wheel
side is known, the wheel can be positioned by turning
it in the direction indicated by the LEDs until the cor-
rect position is reached (see Par. 14.3.6). Once correct
position has been reached, press the pedal brake to
stop the wheel.
Fit the weight to the wheel as indicated in Par. 14.3.2.
Repeat the wheel and weight positioning procedure
for both inner/outer positions. At the end of the proce-
dure, the wheel balancing conditions can be checked
by performing a trial spin.
If the adhesive weight has to be hidden behind spokes,
refer to “weights hidden behind spokes mode”, (see
Chap. 17).
The ALU-S balancing procedure is completed.
14.3.5 Static balancing (STAT)
The STATIC balancing procedure is used to offset
wheel vibrations using 1 weight on a single plane. An
adhesive weight is used inside the rim.
To launch a STATIC measurement, proceed as follows:
- Make sure there are no stones and/or mud on the
wheel. Remove any counterweights. Fit the wheel and
make sure it is properly fastened (see Chap. 12.0).
- Determine the wheel dimensions using the specific
gauge rod (see Par. 14.1.1).
- Close the protection guard to perform the automatic
wheel spin.
In just a few seconds, the wheel runs at normal speed
and the display screens D1-D2 show wheel rotation.
After the spin, the wheel stops automatically, taking
into account the measured unbalance so that the fit-
ting position of the weight is around at “12 o' clock”.
Open the protection guard.
The D2 display screen shows the weight required to
correct the unbalance. The nearby LED show the direc-
tion wheel has to be moved in to fit the weight (Fig. 32).

ing in correct weight fit-
ting point

Once the static unbalance value is known, the wheel can
be positioned by turning it in the direction indicated
by the LEDs until the correct position is reached (see
Par. 14.3.6).
Once correct position has been reached, press the
pedal brake to stop the wheel.
Remove the gauge rod and fit the adhesive weight inside
the pliers as shown in Fig. 33.
