Operation
indicator and make a double mark on the right side
of the tyre exactly perpendicular to and above 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 and above
the main shaft.
•
Press the
PRO-MATCH
key (2) to acquire the valve
position.
Reading OP.8 appears.
•
Press the START key (3) (check run).
If balancing optimisation (silent running) 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
(4) to exit the optimisation program and repeat
optimisation if necessary.
Option 2: do not adjust the tyre on the rim
•
Press the STOP key (4) 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 (4) 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 - ===
Option 2: Abort optimisation
•
Press the STOP key (4) 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.
