BEAD BREAKING AND DEMOUNTING
1)
Clamp the wheel on the spindle as described previously and make sure
it is 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 its hook
has clicked into position on the bar.
4)
Using the joystick, position the wheel so that the bead loosener disk just
touches the outer edge of the ring with taper housing (
see Fig. W/3
).
5)
Turn the spindle while moving forward until the ring with taper housing
detaches from the rim. Take care to prevent the seal from being damaged.
6)
Remove the seal.
7)
Turn the wheel until the opening of the spring ring reaches the 9 o’clock
position (
see Fig. Z/3
).
Position the bead loosener disk against the ring.
Insert lever LC into the relative housing so as to lift the free side of the ring
(
see Fig. Z/3
).
8)
Turn the spindle in the anti-clockwise direction so as to fit the bead
loosener disk under the ring (
see Fig. Z/4
), 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.
