Use and maintenance manual
▪
Rotate the gauge until the correction weight adheres
to the rim
▪
The fact that the weight application position is no longer
vertical is automatically compensated.
To cancel the function, press the
button again.

SPLIT FUNCTION
(hidden weight)
The SPLIT function is used to position the adhesive weights
behind the wheel spokes (angle > 18°) so that they are no
longer visible (for alloy rims). Use this function in the ALU
or STATIC mode where the adhesive weight is applied to
the outer side of the rim.
▪
Perform an unbalance measurement spin.
▪
position the unbalance to be split in the correction
position in order to turn on the laser.
▪
Press and hold the button
until the laser
points to the spoke you wish to correct.
▪
Release the button
.
▪
Turn the wheel in the rotation direction indicated by
the positioning arrows until the second spoke is in the
position indicated by the laser and press
.
▪
Position the wheel as indicated by the LEDs. The
unbalance is indicated on the display.
To return to the normal unbalance indication press
.
The spoke-to-spoke distance must be a minimum of
18° and a maximum of 120° (if not, errors 24,25,26 ap-
pear). Spokes with irregular or inconstant angles can be
compensated.
If the laser is disabled (
MENU
), operate as follows:
▪
Turn the wheel to the correction position of the unba-
lance to be split.
▪
Move one of the spokes where you want to split the
unbalance to 12 o’clock (e.g. 1) and press
.
▪
Following the rotation direction indicated by the posi-
tioning arrows, move spoke 2 to 12 o’clock and press
. The value to use for correction in posi-
tion 2 is displayed.
▪
Position the wheel on spoke 1 following the positioning
arrow indicator and correct the unbalance as indicated
on the display.

5.6 AUTOMATIC MINIMIZATION OF STATIC
UNBALANCE
This program is designed to improve the quality of balancing
without any mental effort or loss of time by the operator. In
fact by using the normal commercially available weights, with
pitch of 5 in every 5 g, and by applying the two counterweights
which a conventional wheel balancer rounds to the nearest
value, there could be a residual static unbalance of up to 4
g. The damage of such approximation is emphasized by the
fact that static unbalance is cause of most of disturbances
on the vehicle. This new function, resident in the machine,
automatically indicates the optimum entity of the weights
to be applied by approximating them in an “intelligent” way
according to their position in order to minimize residual static
unbalance.
