Operation
• Perform compensation according to the indication.
In this way weight minimisation is completed and
unbalance compensation is carried out.
If message E9 appears
Message E9 means that at least one error occurred
during the minimisation program run. Exit the
minimisation program by pressing the STOP (5) key
and repeat the minimisation if necessary.
Option 2: do not invert the tyre on the rim
• Press the FINE (3) key.
The result is recalculated. Indication Un.7 - II or H0
appears.
Option 3
• Exit the minimisation program and return to the
balancing program by pressing the STOP key (5).
The unbalance on the wheel will be displayed.
• Perform compensation according to the indication.
If indication Un.7 - II appears (Fig. 5-37)
It is recommended to turn the tyre on the rim (the right
indication marks light up permanently).
Option 1: Readjust the tyre on the rim (normal
program)
• Turn the wheel according to the right direction
indication and make a double mark on the right side
of the tyre exactly perpendicular to and above the
main shaft (Fig. 5-38).
• Remove the wheel from the unit.
• Readjust the tyre on the rim until the double mark
coincides with the valve (Fig. 5-39).
• Clamp the wheel on the unit and readjust it so that
the valve is exactly perpendicular to and above the
main shaft.
• Press ENTER (1) to acquire the valve position.
Indication Un.8 appears (Fig. 5-34).
• Start the check run (START).
If weight minimisation was carried out correctly
(according to the program cycle), after the check run
the machine returns to the weight application position
selected before minimisation and indicates the residual
dynamic unbalance of the wheel.
• Perform compensation according to the indication.
In this way weight minimisation is completed and
unbalance compensation is carried out.
If message E9 appears
Message E9 means that at least one error occurred
during the minimisation program run. Exit the
minimisation program by pressing the STOP (5) key
and repeat the minimisation if necessary.
