- Press to display the unbalance values (recalculated according to the new dimen-
sions) or perform a wheel spin.
Applying balancing weights. (Fig. 15)
- Select the plane where the first balancing weight is to be applied.
- Rotate the wheel until the central element of the corresponding position indicator lights up.
If the weight to be applied is a conventional clip type(inner side in Alu 2P), apply it on
the corresponding 12 o'clock position. If the weight to be applied is instead the adhesive
type and the weight-holder device is installed, proceed as follows:
- Position it inside the cavity of the weight-holder terminal of the measuring arm (Fig.
15,a,b), with the backing paper of the adhesive strip facing up. Then remove the guard
(Fig. 15c).

- IN THE MACHINE VERSION WITH AUTOMATIC SENSOR move the sensor until
it reaches the indicated position. In this phase, one display continues to show the
unbalance value of the side to be balanced, while the other shows a numerical value
updated on the basis of the sensor position, which becomes zero when the position
for application of the weight is reached.
- IN THE MACHINE VERSION WITH MANUAL SENSOR with the wheel in a centred
position, the machine indicates the unbalance value on a display, whereas the other
display shows the message "d1" or "d2" alternately to the distance value of the plane
corresponding to the body.
- Move the sensor to the position shown on the display in which the message "d1" or "d2"
appears alternately to the distance value (the distance is read on the rule).
- Rotate the end of the measuring arm until the weight adhesive strip is in line with the
rim surface.
- Press the button (Fig. 15d) to eject the weight and make it stick to the rim.
- Return the measuring arm to the rest position (Fig. 15e).
- Repeat the operations to apply the second balancing weight.
