To facilitate this operation, lubricate the bead and the edge of the rim with tyre lubricant
whilst the wheel is rotated. 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 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 (Picture F13.10).

Do not hold your hands on the pool when you bring it back to its work position. Your hands
could be trapped between the tool and the wheel.
8.
Push the double headed tool lever (B, picture F13.10) 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 (A, picture F13.10) can be lowered so that it is out of the way.
Demounting
Tubeless tyre 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 picture F13.11).
Picture F13.11
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 picture F13.12).
