12) Lower the spindle until the tire is resting on the ramp.
13) Move the ramp towards the outside until the tire together with split-ring is completely off the rim.
14) Remove the rim from the spindle.
15) Position the tire on the ramp with the split-ring turned towards the spindle.
16) Clamp the split ring on the spindle as explained in the section of RIM CLAMPING
The tire is not much attached to the split-ring. Any strain on it during positioning or clamping operations could cause it to
detach and fall.
17) Lift the tire assembly.
18) Move the tool carrier arm back to its work position.
19) Position the spindle so that the bead loosener disk is lined up with tyre bead.
20) Turn the spindle and move the disk forward until the tire comes completely off the split ring. (fig. 45)
When the beads come off the rim, the wheel will fall. Always make sure there are no by standers in the work-
ing area.

1) Move the tool carrier arm to its non-working position. If the rim has been removed from the spindle, put it back on the spindle as de-
scribed in the section on “RIM CLAMPING”.
2) Lubricate both beads and the rim with tire manufacturer recommended lubricant .
3) Move the ramp to be able to place the tyre on it.
4) Lower or raise the spindle to centre the rim and the tire.
5) Move the ramp foward until the rim is inserted into the tire.
Move foward with the ramp, until rim is completely in the tire.
6) Put the split-ring on the rim with the lock ring already mounted.
If the rim and the split-ring have slits for fixing devices, make sure they are lined up with each other.
7) Move the tool carrier arm to the outside in its work position with the bead loosener disk facing the tire.
If the split-ring is not inserted sufficiently on the rim, move the spindle until the split-ring is by the disk. Bring the disk forward (with the spindle
turning) until you “observe” the O-ring seating.
