In these cases insert the spacer H between
the pressure pad and its arm (Fig. 9C) in or-
der to compress the tyre more with respect
to the pressure roller.
- Bring the bottom bead up to the top edge
of the rim; in some cases, even if the bead
has already been broken, the bottom bead
will remain in place because it has stuck
to the rim.
If this occurs, use the bead lifter disc, insert-
ing it between the bottom bead and the rim
(Fig. 10), press the rotation pedal and lift.
