8.1.1 Static unbalance

In general the wheels should be balanced dynamically,
i.e. in two correction planes.

If the wheels to be balanced are rather small (e. g.
motorcycle wheels), only static unbalance should be
measured and corrected.

•

For the static imbalance indication press the

key and then select Static

(2,Figure 8-15)

A screen as in

Fig. 8-16

comes up.

For correction diameter and possibilities of correction of
static unbalance see

Recommendations for fitting balance weights
for static unbalance correction

The correction diameter for static unbalance correction
is pro-grammed as follows:

As it is not always possible to correct static unbalance
in the ideal rim position, the following recommendations
for correction

(Fig. 8-17)

should be observed.

Balance clips

(Alu 0 , Alu 4 and Alu 5)

•

With large static unbalance (e. g. 30 g) divide the

unbalance into two fairly equal parts and correct it at
both sides of the wheel, considering the chosen
balancing mode

(Fig. 8-17.1)

•

With small static unbalance fit the balance weight

either in the outer or inner correction plane

(Fig. 8-

17.2 and 8-17.3)

The dynamic unbalance created thereby is negligible.

Note

Figures

–8-17.3

illustrate how balance clips can

be fitted.When adhesive weights are used, or both
types are mixed, proceed analogously depending on
balancing mode.

•

For balancing modes Alu 2 and Alu 3 fit a balance
weight in hidden position inside the rim; in this case
the correction diameter for static unbalance correction
lies inside the rim
