Demounting the tire
When both beads are broken, the tire can be demounted.
1. Press the pedal (Fig. 34 ref. 1) to rotate the wheel clockwise
until the valve stem reaches “hour 1” position.
2. Move the tool vertically (Fig. 34 ref. 2) closer to the edge of
the rim by lowering the lever (Fig. 34 ref. 3). The position of
the tool on the diameter of the rim should already be correct as
the adjustment occurs simultaneously with the previous adjust-
ment of the bead breaker rollers. If this is not the case, it can be
adjusted by pressing the button (Fig. 34 ref. 5) and operating
the handle with a push and pull movement (Fig. 34 ref. 4).
While this phase is being carried out, stay just next to a zone in
the tire where bead breaking has been effectuated.
3. Place the presser cone (Fig. 34 ref. 6) to “4 o'clock” position
as shown in Fig. 34 and press on the tire operating the lever of
the control unit (Fig. 34 ref. 7) downwards, until the tire bead
is placed next to the rim groove.
MOVE VERY CAREFULLY THE TOOLS HOLDER
ARM TO WORKING POSITION, IN ORDER TO
AVOID POSSIBLE HANDS CRUSHING.
