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 vehicles. 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.

5.4.4 - ALU AND STATIC MODES

From the measurement screen, press button to select the type required. The 5-Led displays show

the position where to apply the weights. If a spin has already been performed, the processor automatically

recalculates, for each change of mode, the amounts of unbalance according to the new calculation.

DYNAMIC Balancing of steel or light alloy rims with application of

clip-on weights on the rim edges.

STATIC The STATIC mode is necessary for motorcycle wheels or

when it is not possible to place the counterweights on

both sides of the rim.

ALU - 1 Balancing light alloy rims by ﬁ tting adhesive weights to

the shoulders of the rim.

ALU - 2 Balancing of light alloy rims with hidden application of the

outer adhesive weights. Outer weight position is ﬁ xed.

ALU - 3 Combined application: clip-on weight inside and hidden adhe-

sive weight on outside (Mercedes). Outer weight position is the

same as ALU-2.

ALU - 4 Combined application: adhesive weight outside and clip-on

weight inside.
