4. Make a chalk mark on the tyre external side
at 12 o'clock.
5. Confirm you marked the tyre by selecting
the Kis knob or ENTER.
6. Remove the wheel from the wheel balancer.
7. Turn the tyre on the rim until the mark made
matches the valve (180º rotation).
8. Refit the wheel on the wheel balancer and
confirm the operation described in points 6
and 7 by pressing the Kis knob or the enter
button;
Then, following the new indications on the
monitor:
9. Turn the wheel until the valve gets to 12
o'clock position.
10. Press the the Kis knob or ENTER button to
confirm the execution.
11. Perform a spin.
Now, the real unbalance values of the wheel thus
mounted on the wheel balancer are displayed.
Take the wheel to the position shown on the
monitor. The foreseen unbalances are displayed
by performing the matching and the proportional
improvement which can be obtained if the user
decides to continue the optimisation procedure.
In case optimising is insufficient, or significant
improvements cannot be obtained, select the
Exit key twice (first to exit the pro-
cedure and restart the menu, and then to exit
the programme permanently); perform a spin to
balance the wheel; otherwise, the system goes
to the third and final programme phase.
OPT PHASE 3
Following the indications on the monitor:
12. Turn the wheel up to the position shown on
the position indicator.
13. Make a second mark on the tyre external
side at 12 o'clock. If the indication to invert
the tyre mounting direction on the rim is
displayed, make the second mark on the
internal side.
14. Confirm you marked the tyre again by se-
lecting the Kis knob or ENTER.
15. Remove the wheel from the wheel balancer.
16. Turn the tyre on the rim (and invert mounting
direction, if required) until the mark made
before matches the valve.
17. Refit the wheel on the wheel balancer.
18. Press the Kis knob or ENTER again to confirm
74
the operation.
19. Perform a spin. When the spin is over the op-
timisation programme has been completed
and the weights to be applied to balance the
wheel are displayed.
In case an error compromises the final result,
the machine signals this with the E 6 message.
Now, the procedure can be repeated. The error
message disappears by selecting any of the
available functions.
Special cases
- At the end of the first spin, the message
"OUT 2" may be displayed on the screen.
In this case, it is convenient to exit the
programme by selecting exit
weight values needed to balance the wheel
will be shown on the monitor. The execution
of the programme is interrupted, thus not
achieving the moderate improvement of
the end results. However, the optimisation
procedure can be run by selecting the OPT
continue procedure icon.
- At the end of the second spin, the indication
to invert the tyre mounting on the rim may be
displayed. If you do not want to invert it or
it is impossible to do so, select the disable
tyre inversion icon. the machine will provide
the instructions to complete the programme
without inversion.
The Enable tyre inversion icon restores the
inversion function.
- It is possible to exit the optimisation proce-
dure at any time by simply selecting the Exit
key twice
- If a different working environment is recalled
between one step of the OPT programme
and the next one, the OPT procedure always
remains stored. Therefore, going back to the
start environment, the programme resumes
the execution from the point where it was
interrupted. This situation is possible when
the Temporary Exit icon is selected.
