Operation
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 and
above the main shaft.
• Press the PRO-MATCH key (2) to acquire the valve
position.
Reading Un.4 appears.
• Press the START key (3).
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 critical vehicles).
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 and above 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 and above
the main shaft.
• Press the PRO-MATCH key (2) to acquire the valve
position.
Reading Un.6 appears.
• Press the START key (3).
The machine performs the second measuring run with
the tyre. After the measuring run three readings
are possible:
=== - Un.7
Proceed with the UN program. It is recommended that
the tyre be turned over on the rim.
Un.7 - ===
Proceed with the UN program. It is recommended that
