vance the bead breaker disc with small forward
movements, following the rim profile as much
as possible with the disc.

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.

the beads have been broken, use the bead
breaking disc to push against the inner side of
the tyre until both beads come out of the rim
(see fig. 21).
