5.5.3 - Unbalance optimization
The symbol is displayed automatically for static unbalance exceeding 30 grams (1.1 oz). The program allows
reducing the total unbalance of the wheel by compensating, when possible, the unbalance of the tyre with that of the
rim. It requires two spins with rotation of the tyre on the rim in the second spin.
Press + after a first spin and follow the instructions appearing on the monitor.
5.5.4 - Correction mode
After having performed automatic measurement of the inner side, it is possible to place the correction weights as
required by pressing pushbuttons and .
N.B.: In the event of automatic measurement of both sides, if the difference between the inner and
outer diameters is greater than or equal to 2”, the system sets the inner side spring weight. To
modify this presetting, press the button. The external side may only be “adhesive”.
To display static unbalance, press the button on the measurement screen (for ALUS static, the inner side
diameter is always considered).

adaptor in the same position.
Remove the wheel from the balancer.
Turn the tyre 180° on the rim.
Re-assemble the wheel on the balancer by positioning the rim reference mark with
the adaptor’s.
