Balancing the wheel
•
Swing the gauge arm out towards the rim and press the
weight firmly against the rim using the ejector
(Fig.
50, item 5)
.
•
Swing the gauge arm in and return it to its home posi-
tion.
•
Firmly press the adhesive weight on the rim by hand.
8.2.3 How to fit adhesive weights based on given
dimensions
If the correction positions are not accessible with the gauge
arm and the rim dimensions have been entered using the
function keys and rotating the wheel:
•
Fit adhesive weights in the given positions according to
the balancing mode. Make sure to observe the given
positioning dimensions
(Fig. 51)
.
8.3 Check run
•
When the balance weights are fitted start a check run.
On completion of the check run when the wheel is perfectly
balanced, both digital displays show 0 and the OK indicators
come up
(Fig. 52)
.
Note
If both amount readings are 0, but there is no OK reading,
dynamic unbalances below the tolerance limit (suppression
preset to 1/4 ounce) add to a static unbalance above the
tolerance limit. These residual unbalances are read out upon
operation of the FINE key (Fig. 11b, item 11) and should then
be balanced.
8.4 Static unbalance
•
To display static unbalance press the key to select the
display of static unbalance (S/D key; Fig.11a, item 10). The
amount of unbalance is then read out at the left digital display.
The direction to be indexed and the correction
position are indicated by both direction indicators
(Fig. 53)
.
For correction diameter and possibilities of correction of static
unbalance see
