Recommendation to readjust tire on the rim (the right display
segments light up permanently).
Choice 1: Readjust tire on the rim (standard program)
• Index the wheel following the right direction indicator
and provide a double mark on right side of the tire at
12:00 o'clock.
• Remove the wheel from the machine.
• Readjust the tire on the rim until the double mark coin-
cides with the valve.
• Clamp the tire/rim assembly on the machine and turn
until it is at the 12:00 o'clock position.
• Press the PRO MATCH key to enter the valve position.
Reading Un.8 comes up.
• Press the START key (check run).
If the minimisation run has been carried out correctly following
the above sequence of operations, the balancer will return to
the balancing mode selected before minimisation and read out
the dynamic unbalance still left in the wheel (Fig. 128).
• Balance the wheel according to the readings.
Reading of error code E9
If E9 is read out, at least one error was made with respect to
the sequence of operations when performing minimisation
(see § 11. Error codes). Abort the minimisation program by
pressing the STOP key and, if desired, start minimisation once
again.
Choice 2: Do not readjust tire on the rim
• Press the STOP key to return from the minimisation to
the balancing program.
The unbalance present in the wheel is read out.
• Balance the wheel according to the readings.
