Operation
•
Press the PRO-MATCH key (2).
The OP.1 reading appears.
•
Readjust the rim so that the valve is exactly
perpendicular to and above the main shaft.
•
Press the PRO-MATCH key (2) to acquire the valve
position.
The OP.2 reading appears.
An incorrect valve position entry can be corrected
afterwards.
Weight minimisation
If no optimisation, but only weight minimisation (i.e.
without compensation run for the rim without tyre),
proceed as follows:
•
Clamp the complete wheel (rim and tyre).
•
Press F (1) + PRO-MATCH (2) if minimisation is
starter separately from optimisation.
The OP.1 reading appears.
•
Press the
F
key (1) to activate the weight
minimisation program.
The Un.3 reading appears. Run the minimisation
program.
•
With program OP.2 the rim compensation run can
still be omitted. Go to the next step in the program
by pressing the
F key (1).
The UN.4 reading appears.
•
Continue the minimisation program.
The valve position entered with OP.1 is automatically
used.
Continuing balancing optimisation
•
Press the START key (3) to start the rim
compensation run without the tyre.
After the measuring run the OP.3 reading appears.
•
Mount the tyre and inflate 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.
