TUBELESS AND SU-
PERSINGLE WHEELS
BEAD BREAKING
1) Clamp the wheel on the turntable, as
previously described, and ensure that it is
deflated.
2) Move the mobile control unit to working
position C.
3) Lower the tool holder arm into its working
position until it hooks with the ratchet.
WARNING
Always make sure that the arm is correctly
hooked to the carriage.
4) Using the control lever, position the wheel
so that the external rim profile skims the bead
breaker disc (fig.19).
WARNING
The bead breaker disc must not press against
the rim but the tyre bead.

5) Rotate the wheel and, at the same time,
advance the bead breaker disc with small
forward movements, following the rim profile
as much as possible with the disc.
6) Continue until the first bead is completely
detached.
To facilitate the operation, lubricate the bead
and the shoulder of the rim using the specific
grease or a soapy solution, keeping the wheel
in movement.
WARNING
To avoid all risk, lubricate the beads turning
the wheel CLOCKWISE if you are working on
the outer side or ANTICLOCKWISE if working
on the inner side.
N.B.: Bear in mind that the more strongly the
tyre is fixed to the rim, the more slowly the
disc must be advanced.
7) Move the tool holder arm away from the
rim edge.
Release the ratchet, raise the arm to its non-
working position, shift it and rehook it in its
second working position (fig.20).
WARNING
Never hold onto the tool with your hand
when moving it to the working position: it
could be crushed between the tool itself
and the wheel.
8) Press the lever (B, Fig. 20) and rotate the
tool by 180°, which locks automatically.
9) Move the mobile control unit to working
position D.

10) Repeat the operations described above in
points 5 and 6 until the second bead is com-
pletely detached.
N.B.: During bead breaking, the hook tool
(A, Fig. 20) may be lowered so it does not
impede work.
