DEMOUNTING
Tubeless tires can be demounted in two ways:
1) If the tire is not difficult to demount, once the beads have been loosened, use the bead disk to push against the inside face of the
tire until both beads come off the rim (See Fig. H). Always keep the tire rotating while pushing on it with the bead disk.
2) With Supersingle or very hard tires the procedure described above cannot be used. The hook tool will have to be used as follows:
- Transfer the tool carrier arm to the outside face of the tire.
- Insert lever (17, Fig. I) between rim and bead at the right of the tool.
-Press down on the lever and lower the wheel to bring the edge of the rim about 2 inch (5 cm) from the hooked tool.
-Turn the wheel counterclockwise pressing down on lever until the bead is completely off.
-Move the tool carrier arm to its non-working position and then move it to the inside face of the tire.
- Rotate the wheel and at the same time move the hook tool forward inserting it between rim and bead until it is anchored to the bead
(See Fig. I).
-Move the rim 1,5-2 inch (4-5 cm) from the tool taking care that it does not unhook from the bead.
-Move the hook tool towards the outside until the red reference dot is by the outside edge of the rim.
-Place the tool carrier arm in the working position, then use the bead disck to push against the inside face of the tire (see fig. H). It is
best to do this with the weel turning
