Reading OP
.5
– I (1 Reference mark
Fig. 5-35)
• After the measuring run readjust the wheel following
the direction indicator and make a chalk mark on
the right side of the tire exactly perpendicular to and
above the main shaft.
• Readjust the tire on the rim so that the reference
mark made is aligned with the valve (use tire
changer).
• Clamp the wheel on the balancer and readjust it until
the valve is exactly perpendicular to and above the
main shaft.
• Press the ENTER
key (1) to acquire the valve
position.
The OP.6 reading appears (Fig. 5-34).
• Spin the wheel (START).
After the measuring run four readings are possible:
II - OP.7
Proceed with the OP program. It is recommended that
the tire be turned over on the rim.
OP.7 - II
Proceed with the OP program. It is recommended to
shift the tire on the rim (manual rotation).
H0
Optimum condition has been achieved and cannot be
improved.
H2
Silent running cannot be improved.
• Press STOP (5) to exit.
However, it is
possible to readjust the tire relative to
the rim to achieve signifi cant weight minimization (i.e.:
smaller balance weights) without having an adverse
effect on silent running.
Depending on the readings, there are several
possibilities for proceeding with the program. These
possibilities are described below.
Reading II - OP.7 (Fig. 5-37)
Turn the tire over on the rim (the left display bars are
rotating).
Option 1: Turn the tire over on the rim (normal program).
• Readjust the wheel according to the left direction
indicator and make a double mark on the left side
of the tire exactly perpendicular to and above the
main shaft.
• Remove the wheel from the machine.
• Turn the tire over on the rim and readjust until the
double mark coincides with the valve.
• Clamp the wheel on the balancer and readjust it so
that the valve is exactly
perpendicular to and above
the main shaft.
• Press the ENTER key (1) to acquire the valve
position.
