If the unbalance is out of tolerance:

 At the end of the spin, the wheel automatically 

comes near to the outer side (on the inner side if the 

outer side is already within tolerance). In case of both 

sides (or static) within tolerance, no approaching is 

carried out. The spindle is automatically locked in cor-

rection position (if not disabled the spindle lock and for 

rotation speeds less than 20 rpm).

If the unbalance is out of tolerance:

1. At the end of the spin, the wheel automatically comes near to the outer side (on the inner side if the

outer side is already within tolerance). In case of both sides (or static) within tolerance, no
approaching is carried out.

 The spindle is automatically locked in correction position (if not disabled

the spindle lock and for rotation speeds less than 20 rpm).
If the acoustic signal is enabled (

MENU - ACOUSTIC SIGNAL

), a beep will sound when the correction

position has been reached.

2. The symbol 

 is shown on the display on the side corresponding to the active correction plane.

If a flashing arrow appears, move slightly by hand the wheel to complete positioning on the correction plane.

3. Manually apply the number of weights shown on the display on the rim at 12 o’clock using clip-on weights:

.

4. Press

 to position the wheel in proximity of the other side and correct the unbalance according to 

what is shown on the screen

5. After applying the weights, spin the wheel to check the correction made checking that both planes are within

tolerance.

Enabled buttons:

measuring spin with closed guard/automatic wheel positioning in proximity of the correction position  
with open guard

 is shown on the display on the 

side corresponding to the active correction plane.

If a flashing arrow appears, move slightly by hand 

the wheel to complete positioning on the correction 

plane.

Note:

 If the out-of-balance is less than the chosen 

threshold value, “0” appears instead of the out-of-

balance value to indicate, on that particular side, that 

the wheel is in tolerance; If AUTOADAPTIVE is dis-

abled, press
