Following c. the direction of rotation indicated by the
position LED’s, move spoke 2 to12 o’clock and press
. The value to use for correction in position 2 is
displayed.
Mov d. e spoke 1 to the correction position as indicated
by the position LED’s
If the “OPPOSITE POSITION” function is enabled (see the
relative paragraph), the bottom correction position (at 6
o’clock) is indicated by the central LED coming on for each
phase column.
To return to the normal unbalance indication press any
button.
INFORMATION
The distance between the spokes must be at least 18°
and at most 120° (if not, the errors 24,25 or 26 appear).
Spokes with irregular or inconstant angles can be
compensated.
5.6 UNBALANCE OPTIMISATION
This operation is performed to reduce the static unba-
lance of the wheel.
It is suitable for static unbalance values in excess of 30
grams.
I a. f no unbalance was measured before, START appears
on the display. Press this button to proceed.
Mak b. e a reference mark on the flange and the rim (using
a piece of chalk, for example).
With the aid of a tyre remover, turn the tyre on the rim
by 180°.
Refi t the wheel in such a way that the reference marks
on the rim and the fl ange coincide.
Press START to begin reading.
RH displ c. ay: percentage reduction value
LH display: actual static unbalance value which can be
reduced by rotation
Ma d. rk the two positions of the rim and tyre, and turn the
tyre on the rim until the positions coincide to achieve
the optimisation shown on the display
To cancel optimisation at any time, press .
5.7 OPPOSITE POSITION
The normal balancing condition requires the correction
weight to be applied at the top (12 o’clock) when the
symbol is displayed:
If OPPOSITE POSITION is enabled, the eventual appli-
cation position for the bottom weight is also indicated
next to the positioning arrows to facilitate cleaning the
rim and the relative application of adhesive weights. The
symbol used is:
