Operation
Reading OP.7 - ===
Readjust the tyre on the rim (the right display bars light
up permanently).
Option 1: Readjust the tyre on the rim
(adjustment program)
•
Readjust the wheel following the right direction
indicator and make a double mark on the right side of
the tyre exactly perpendicular to the main shaft.
•
Remove the wheel from the machine
•
Readjust the tyre on the rim until the double mark
coincides with the valve.
•
Clamp the wheel on the balancer and readjust so that
the valve is exactly perpendicular to the main shaft.
•
Press the PRO-MATCH key (2) to acquire the valve
position.
Reading OP.8 appears.
•
Perform the check run.
If balancing optimisation has been carried out correctly
according to the program cycle, after the check run
the machine automatically returns to the type of weight
positioning previously selected and indicates the
residual dynamic imbalance on the wheel.
•
Balance the wheel according to the readings.
Both optimisation and balancing are accomplished.
Message E9
Message E9 means that at least one error occurred
during the optimisation cycle. Press the STOP key to
exit the optimisation program and repeat optimisation
if necessary.
Option 2: do not adjust the tyre on the rim
•
Press the STOP key 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.
Reading H0
•
Press the STOP key 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.
The optimum balancing optimisation condition has been
achieved and cannot be improved.
Reading H2
Silent wheel running cannot be improved. However, it
is possible to achieve weight minimisation (readings
with code Un.).
Option 1: Weight minimisation
•
Press the F key to continue the program.
As a result reading is === - Un.7 or Un.7 - ===
