4.3 - SPLIT FUNCTION
►
(UNBALANCE RESOLUTION)
The SPLIT function is used to position the adhesive weights behind the wheel spokes (angle > 18°) so that
they are not visible. This function should be used in ALU mode where the adhesive weight is applied on the
outside. Input the wheel dimensions and do a spin.
a. Turn the wheel to the outside unbalance correc-
tion position as indicated by the machine
b.
Position one spoke at 12 o'clock (e.g. 1) and press
c. Following the rotation direction indicated on the
display, position spoke 2 at 12 o'clock and press
d. Position the wheel as indicated by the LEDs.
The display indicates the value to be used for the
correction in position 1
e. Repeat the operation for the other spoke
To return to normal unbalance display, press any button.
NOTE: 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 compensa
ted.
This operation is required if no unbalance has a.
been measured previously; otherwise go to the
next step
Mark with chalk a reference point on the adapter b.
and rim. With the aid of a tyre changer, turn the
rim on the tyre by 180°. Refi t the wheel with the
reference mark coinciding between rim and adap
ter
c. RH display: percentage reduction
LH display: actual static unbalance which can be
reduced by matching
d. Mark the two positions of the rim and tyre, and
turn the rim on the tyre until the positions
correspond in order to obtain the optimization
results shown on the display.

4.4 - UNBALANCE OPTIMIZATION
►
This function serves to reduce the amount of weight to be added in order to balance the wheel ▪
It is suitable for static unbalance exceeding 30 g. ▪
Improves the residual eccentricity of the tyre and hence driving comfort. ▪
