DANGER!
The bead loosener disk must NOT be pressed against the rim but against the tire bead.
5) Rotate the wheel and at the same time, advance the loosener disk plate with small forward movements following the profile of the
rim.
6) Continue until the first bead is fully detached.
To facilitate this operation, lubricate the bead and the edge of the rim with tire lubricant whilst the tire assembly is rotated.
CAUTION!
To avoid all risk, lubricate the beads turning the tire assembly CLOCKWISE if you are working on the outside
face and COUNTERCLOCKWISE if working on the inside face.
4) Operating from the mobile control centre, manoeuvre the wheel until the outside of the rim skims the bead-loosener disk (fig. F).
