- For easier bead engagement, it might be very helpful to use the bead breaker disc on
the underside of the tyre (D).
- To do this, repeat the steps up to point 7a.
10 • Demounting the top bead (fig.19)
- Check that the tool has engaged with the tyre bead.
- Operate control 1 to prepare for the subsequent demounting (A) (this must be done
with the wheel at a standstill and not rotating).
- Check that the bead of the tyre has not slipped back into the rim on the upper side. If
necessary, use a clamp and/or bead presser for assistance (fig.34A).
- Now, and only now, operate the pedal 2 until the bead is completely demounted (B).
- Here again, it might be helpful to use the bead breaker disc on the underside of the
tyre (fig.20).
- During demounting, if the tyre should tend to slip on the edge of the rim, the HELP
accessory supplied can be used (see "PRACTICAL HINTS, RECOMMENDATIONS AND
USEFUL INFORMATION").
11 • Engaging the bottom bead (fig.20)
(Demounting using the tool head)
- Place the tool on the edge of the rim (A).
- Push the bead breaker disc against the bottom bead (B) using control 1.
-Using control 2, operate the hook and engage the bottom bead of the tyre (C-D).
- Operate the pedal 3 to rotate the wheel until the tyre is completely demounted from
the rim (E).
12 • Demounting the bottom bead (fig.20a)
(Rapid system when possible)
- Operate control 1 and raise the bottom bead of the tyre (A) until it is level with the top
bead of the rim (B).
-Obtain disc penetration by keeping button 2 pressed (C).
- Keep button 2 pressed, start to rotate the wheel (pedal 3) and at the same time raise
the disc a little at a time (control 1). Rotate until the tyre is completely demounted.
12a • Demounting the bottom bead (fig.20b)
- For reverse rims the disc stroke range can be increased by turning the bead breaker
and tipping the disc over. (fig.3 - 4).
13 • Demounting completed (fig. 21)
- When demounting is completed (A) release the penetration button (2) and lower the
bead breaker disc (control 1) (B).
- Bring the bead breaker unit to the rest position (C) by pressing button 3.
To make full use of all a tyre's characteristics and have the necessary guarantees of safety
in use, a series of precautions must be taken when choosing and fitting tyres.
The tyre's dimensional, construction and service characteristics are provided by the
markings on its sidewall.
Once the appropriate tyre has been chosen from those approved for use on the vehicle,
the mounting procedure can begin.
