Operation
After the measuring run the
OP.3
reading appears.
•
Mount the tyre and infl ate correctly (see note below).
Note
For mounting and demounting (tyre changer) and tyre
turning or readjustment on the rim, always apply a
suffi cient amount of tyre lubricant on the tyre beads and
the rim edges and shoulders. Each time the position
of the tyre is changed on the rim, infl ate the tyre to
overpressure (approx. 3.5 bar) then defl ate to correct
tyre pressure.
Make sure the centring line is correctly positioned on
the tyre bead.
•
Clamp the wheel.
•
Position the valve exactly perpendicular to and
above the main shaft.
•
Press the
ENTER
key
(
1
)
to acquire the valve
position.
OP.4
appears
(

)
.
•
Spinn the wheel
(START
).
The measuring run is carried out. After the measuring
run two readings are possible:
OP.5 - H1
Further optimisation is not recommended, but possible.
OP.5
– I
(1 Reference mark
Fig. 5-35
)
Continue with the OP program.
Reading
OP.5 - H1
If
OP.5 - H1
appears, further optimisation is not
recommended, since the measurement values which
activated the optimisation recommendation are below
the limit value. However, it is possible to continue
optimisation for the most silent possible wheel running,
reducing imbalances below the limit value (critical
vehicle).
To continue optimisation
•
To continue with the OP program proceed as
specifi ed for
OP.5 – I
(given below).
To abort optimisation
•
Press the
STOP
key to return to the balancing
program and balance the wheel according to the
readings
(
F
5.9)
.
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 tyre exactly perpendicular to
and above the main shaft.
•
Readjust the tyre on the rim so that the reference
mark made is aligned with the valve (use tyre
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
)
