ENGLISH • Instructions manual
37) Take the mobile control unit to work position B.
38) When the wheel is resting on the platform, check to make sure the valve is
perfectly centered with its hole. If it is not, turn the spindle slightly to adjust the
position. Fix the valve with its locking ring and remove the extension.
39) Close the arms of the spindle completely. Support the wheel to prevent it fall-
ing off.
DANGER:
This operation can be extremely dangerous.
Do it manually only if you are certain you can keep the
wheel balanced.
For large and heavy tyres an adequate lifting device must
be used.
40) Translate the turntable to disengage the wheel.
41) Remove the wheel.

12.4 WHEELS WITH 3-PIECE SPLIT RINGS

BEAD BREAKING AND DEMOUNTING
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 fol-
lowing 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) Turn the wheel until the opening of the spring ring reaches the 9 o'clock posi-
tion (see Fig. Z).
Set the bead loosener disk against the ring.
Insert lever LC into the relative housing so as to raise the free side of the ring (see
Fig. Z).
7) Turn the spindle in the anti-clockwise direction so as to fit the bead loosener
disk under the ring (see Fig. Z/2), which can then be removed.
CAUTION: Hold the ring with the hands (in the 12 o'clock position) as the
spindle is turned to prevent it from accidentally dropping.
8) Remove the split-ring.
