8 • Upper tyre bead coupling (fig. 21) A-B-C
- Create enough space between the rim and
the tyre with the bead breaker disc to allow
the demounting tool to tilt.
- Operate control 28 for demount tool (A-B-C)
tilting.
- It is important to rotate the turntable slightly to
facilitate engagement of the bead.
- For easier bead coupling, it might be very helpful
to use the bead breaker disc on the lower part
of the tyre.
- To perform this, use control 23.

9 • Upper bead demounting (fig. 22)
- Check that the tool has engaged with the tyre
bead.
- Operate (control 28) to get the machine ready
for the subsequent demounting operation
(performed with the wheel at a standstill and
not rotating).
- Make sure that the tyre has not beaded in on
the operator's side. If necessary, use a clamp
and/or a bed presser.
- Only then operate pedal (15) until the bead is
completely demounted.
- Here again, it might be helpful to use the bead
breaker disc on the lower part of the tyre.
- Upon demounting, if the tyre tends to slip on the
rim edge, the HELP accessory supplied can be
used (see "PRACTICAL HINTS, ADVICE AND
USEFUL INFORMATION").
