Possible Mistakes:
- The program can only split the weights on the right
plane of the wheel
- If a two tone audible signal is heard it means that the
balance position is not exactly at „12 o´ clock positi-
on“.
- The position of the spokes cannot be calculated by
the program when they are more than 150° apart and
if both spokes are positioned left or right of the original
weight placement area.
9 Matching
Applicable to all machines BM xx Touch Touch and for
all programs.
Purpose:
Wheels with large unbalance weights (larger than 60g in
either plane) should be matched.
This large unbalance can be caused by the unbalance
of the rim and unbalance of the tyre combining toge-
ther at the same angle causing the wheel to become
top heavy.
Matching optimizes the rim to the tyre in the best com-
bination to reduce the large unbalance.
Routine:
The result of a normal balance run is seen to be too high
on any plane.
The Symbol shows a to high static imbalance.
Touching the button starts the matching pro-
gram.

The tire needs to be dismounted from the rim, then
clamp the rim to the machine with the valve positioned
on the „12 o´ clock position“.
Start the measuring run by touching the
button.
In this measuring run the imbalance of the rim is de-
tected.
