BEAD BREAKING AND DEMOUNTING

WHEELS WITH 3-PIECE SPLIT RINGS

1) Clamp the wheel on the spindle as described previously and check to make sure it has been deflated.
2) Take the mobile control unit to work position C.
3) Lower the tool carrier arm (14, Fig. D) to its work position until it is locked
in position by its hook.
4) Position the bead loosener disk level with the rim (See Fig. W).
5) Turn the spindle and at the same time move the disk forward a bit at a time
following the contour of the rim until the first bead is completely free.
NB: lubricate while doing this.
CAUTION! If the tyre has an inner tube, work very carefully and be prepared to
stop the disk immediately once the bead has been broken so as not to damage
the valve and the inner tube.
6) Repeat this procedure but this time bring the disk against the split-ring (See
Fig. Z) until the lock ring is freed.
Remove this with the special lever LC (19, Fig. Z) or with the help of the disk.
7) Remove the split-ring.
8) Move the tool carrier arm (14, Fig. D) back from the edge of the rim.
Release the hook and tip the arm to its non-working position.
Move the tool carrier arm to the inside plane of the wheel.
9) Press lever (19, Fig. D) and turn the tool head 180° which will automatically
lock in this position. Lower the arm to its working position.
10) Turn the spindle and at the same time bring the bead loosener disk up
against the tyre following the contour of the split-ring until the second bead
has been broken.
NB: Lubricate during this process.
Continue to move the disk forward until about half the tyre has demounted from
the rim (See Fig. K).
11) Move the tool carrier arm to its non-working position.
12) Move the platform (4, Fig. A) directly under the wheel.
13) Lower the spindle until the wheel is resting on the platform.
