ENGLISH
If the laser option 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 position 2
is displayed
▪ position the wheel on spoke 1 following the positioning
arrow indicator and correct the unbalance as indicated
on the display.
To return to the normal unbalance indication press .
5.5 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.
