BEAD BREAKING AND DEMOUNTING
WHEELS WITH 3-PIECE RINGS
1) Clamp the wheel on the spindle as described previously and check to make
sure it has been deflated.
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 tire 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 TL
(19
Fig. Z)
or with the help of the disk.
7) Remove the split-ring.

(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 180º which will automatically
lock in this position. Lower the arm to its working position.

Turn the spindle and at the same time bring the bead loosener disk up
against the tire 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 tire has demounted from the rim
(see Fig.
K).
11) Move the tool carrier arm to its non-working position.
