- Position the bead breaking disc (as illustrated in fig. “Phase 1”) to
remove the top part of the tyre. To do this, move the two levers to -
gether (re. A), accompany the disc support with your hand upwards
and release the two levers so as to block the disc support.
- Position the bead breaking carriage on the tyre using control but-
tons C and D on the control panel.
- The bead breaking disc should be approximately 5mm from the
outer edge of the rim. Block the disc in position by turning selector
A.
- Turn the spindle flange until the valve reaches the “2 o’clock” po-
sition.
- Lower the bead breaking disc until it touches the tyre, using con-
trol buttons E to raise and F to lower.
- At this stage, start to turn anti-clockwise.
NB: The spindle flange can turn at 2 different speeds, which the
operator may choose on a case-to-case basis for the most suitable
working requirements.
- When turning the tyre, push the bead breaking disc down under
the edge of the rim and then press and hold down the “over stroke”
function button G and continue pushing the disc down (in sections)
until the bead of the tyre has come away from the rim.
- Once the bead breaking disc has created enough space, start to
lubricate carefully, both on the internal part of the rim and on the
bead of the tyre; use a specific lubricant for tyres to do this. (phase
2)
- Once the tyre has come off the rim, put the bead breaking disc
back in its initial position (out of the work zone).
Release button G and raise the disc. Press button B and turn the
bead breaking carriage outwards out of the work area.
- Turn the bead breaking disc downwards (follow the instructions of
“phase 1”) (ref. B)
- Raise the bead breaking disc until it touches the tyre, using control
buttons E to raise and F to lower.
- At this stage, start to turn anti-clockwise.
NB: The spindle flange can turn at 2 different speeds, which the
operator may choose on a case-to-case basis for the most suitable
working requirements.
Phase 1
If there is a sensor, make sure it does not come into
contact with the lubricant.
