1. Remove all wheel-weights from the rim. Remove
the valve stem or core and deflate the tire completely.
2. Position the tool close to the rim edge (fig.37).
When the lock ring is stuck to the tire bead, (on the
O.T.R. tires) to loosen the bead, it is necessary to hold
the ring to the rim with the appropriate clamp
#874007611 (optional accessory).

3. Turn the chuck counterclockwise and loosen the
bead as described in #5.2.1.-5.2.3. Do not lubricate.
4. To remove the lock ring, squeeze one edge with
the proper bar and place the bead loosener disc as
shown in fig.38.

5. Turn the chuck clockwise (or counterclockwise)
until the lock ring is completely removed.
No one should stand in front of the wheel
when removing the lock ring.
Continue to demount all components of the rim man-
ually or with the disc tool.

damage the valve stem (fig.39).
