· Now turn the turntable.
· Bring the bead breaker disc near the bead
and start to push it outward.
Be careful that the bead does not tip on
the rim edge while it is being pushed out.
If necessary, as soon as the disc has passed
the rim edge, lower the turntable a few
cm. This will decrease the bead tension
and make it easier to demount the wheel.
(fig. 32).
· NOTE
For some types of rims, such as with a
double well or skidder, a demounting tool
and a manual lever must be used.
Using the search control, (control 4, fig.
14), insert the tool between the rear bead
and the rim as shown in (fig. 32a), until the
bead is hooked by the tool. Return the tool
to a horizontal position. At this point, turn
the turntable and use the shaped profile of
the tool to push the bead forward until the
tyre is completely demounted. If the tyre
has difficulty in bypassing the rim edge,
use the provided manual lever.
To hook the bead in the case of narrow
rims with a reduced well, it may be helpful
to turn the turntable in an anticlockwise
direction.

N.B. At the end of the demounting phase,
the tool and the rim are in the correct posi-
tion for the mounting procedure; otherwise,
position the tool so that the reference mark
is flush with the rim edge (Fig. 33).
Tighten the pliers (A, Fig. 33) on the front
edge of the rim.
