Operations
7.
Turn the chuck counter-clockwise until the outer bead
is completely demounted (Fig.5.8-6).
8.
If the tire is tube-type, push the valve stem towards the
inside of the rim.
9.
Lift the toolholder arm to the rest position.
Shift the tire from the rim, moving the toolholder carriage
towards the outside: this will make it much easier to
extract the tube (Fig.5.8-7).
10.
Place the hook tool as in Fig.5.8-8.
The edge of the hook should be about 2-3 cm (1") away
radially from the rim edge and about 2-3 cm (1") to the
outside.
11.
Put the long tire bar in between the bead and the rim.
12.
Rotate the chuck counter-clockwise until the tire is
completely demounted.
DURING THE FINAL PHASE OF THE DEMOUNTING
OPERATION REMOVE THE TIRE BAR AND HOLD THE
TIRE WITH BOTH HANDS, IN ORDER TO KEEP IT IN
A VERTICAL POSITION
