DANGER!
The bead breaker disk must NOT be pressed against the rim but against the tyre bead.
5) Rotate the wheel and at the same time, advance the bead-breaker plate with small forward movements following the profile of the rim,
with the plate.
6) Continue until the first bead is fully detached.
To facilitate this operation, lubricate the bead and the edge of the rim with tyre lubricant whilst the wheel is rotated.
CAUTION!
To avoid all risk, lubricate the beads turning the wheel CLOCKWISE if you are working on the outside plane and
ANTICLOCKWISE if working on the inside plane.
N.B.: Remember that the stronger the tyre's adherence to the rim, the slower must be the disk's penetration.
7) Bring the tool carrier arm (14, Fig. F) back from the edge of the rim.
Release the hook, raise the arm to its non-working position, shift it and rehook it
in its second work position (Fig. G).
DANGER!
Do not hold your hands on the tool when you bring it back
to its work position.
Your hand(s) could be trapped between the tool and the
wheel.
8) Push the double headed tool lever (19, fig. G) and turn the head 180° until it
locks automatically.
9) Take the mobile control unit to work position D.
10) Repeat the operation previously described until the second bead is completely
broken.
N.B.: During the bead breaking, the claw (18, fig.G) can be lowered so that it is
out of the way.
DEMOUNTING
Tubeless tyres can be demounted in two ways:
a) If the tyre is not difficult to demount, once the beads have been loosened, use
the bead disk to push against the inside plane of the tyre until both beads come
off the rim (See Fig. H).
b) With Supersingle or very hard tyres the procedure described above cannot be
used.
The hook tool will have to be used as follows:
1) Transfer the tool carrier arm to the outside plane of the tyre.
2) Take the mobile control unit to work position C.
3) Rotate the wheel and at the same time move the hook tool forward inserting it
between rim and bead until it is anchored to the bead (See Fig. I).
