Operation
Option 2: Abort optimisation
•
Press the STOP key (3) to exit the OP program
and return to the balancing program.
The imbalance on the wheel is shown on the readout.
•
Balance the wheel according to the readings.
Weight minimisation program cycle
If the rim compensation run was omitted and the F key
(1) was pressed to go directly into the minimisation
program (reading Un.), proceed as follows.
- Clamp the wheel.
- Position the valve exactly perpendicular to the main
shaft.
- Press the PRO-MATCH key (2) to acquire the valve
position.
Reading Un.4 appears.
- Perform the run.
The measuring run is carried out. After the measuring
run two readings are possible:
Un.5 - H1
Further minimisation is not recommended, but is
possible.
Un.5 – Reference mark
Continue with the UN program.
Reading Un.5 - H1
If Un.5 - H1 appears, further minimisation is not
recommended since the measurement values do not
exceed the limit values. However, it is possible to
continue minimisation so as to achieve an improvement,
if only slight (e.g.: for vehicles with problems).
To continue minimisation:
- Proceed as indicated for reading Un.5 – Reference
mark.
To abort minimisation:
- Press the STOP key to return to the balancing program
and balance the wheel according to the readings.
Reading Un.5 – Reference mark
- After the measuring run readjust the wheel according
to the direction indicator and make a chalk mark on
the right side of the tyre exactly perpendicular to the
main shaft.
- Readjust the tyre on the rim so that the mark coincides
with the valve (use the tyre changer).
- Clamp the wheel on the balancer and readjust it so
that the valve is exactly perpendicular to the main shaft.
- Press the PRO-MATCH key (2) to acquire the valve
position.
Reading Un.6 appears.
- Perform the run.
