Any strain on it during positioning and/or
clamping could cause it to detach and fall.
20) Move the mobile control unit to working
position D.
21) Lift the wheel.
22) Return the tool holder arm to the working
position.

disc is perfectly lined up with the tyre bead.
24) Turn the turntable and at the same time
move the bead breaker disc forward until the
tyre comes out of the side ring completely.
N.B.: This double bead breaking procedure
can be avoided by using the PAIR OF CLAMPS
(upon request) that make it possible to fasten
the side ring to the rim and break them at the
same time.
The pair of clamps (Fig. 37) is supplied with
instructions for proper mounting and use.
WARNING
When the beads come off the rim, the tyre
will fall.
Make sure no one is in the work area.

position B.
4) Move the mobile platform outward so that
the tyre can be placed onto it.

the wheel.
N.B.: If the tyre is not inserted sufficiently
