emounting
• Remove the valve plunger and let all the air
out of the tyre.
• NB: If necessary, remove the valve fixing nut
and let the sensor to fall into the tyre.
• Place the sensor at 3 o’clock.
• Lower the bead breaker disc and start the
rotational bead breaking stage.
• Lubricate the bead and continue rotational
upper bead breaking until the sensor is at 12
o’clock and not beyond.
• Raise the bead breaker disc.
• Move the sensor to 6 o’clock.
• Push in the bead breaker disc and fit the
gripper at 2 o’clock.
• Apply plenty of lubricant and break the lower
bead.
• Move the gripper to 2 o’clock (sensor at 6
o'clock).
• Position the demounting unit (tool head).
• Lower the swing tool to find the bead.
• Rotate clockwise so that the gripper is at 6
o’clock (sensor at 10 o’clock).
• The bead is now engaged.
• Engage the bead with the demounting head.
• Rotate clockwise to demount the tyre, with
the bead breaker disc in the down position.
• Remove the gripper.
• Now demount the tyre underside, taking care
not to damage the sensor.
t
yre mounting
• Refit the valve sensor (if removed).

• Turn the tyre so that it touches the mounting
head and starts to be mounted on the rim.
• Rotate the tyre until the lower bead is
mounted.
• Turn the sensor to 4 or 5 o’clock.
• Lower the bead breaker to allow a bead presser
gripper to be inserted at 3 o’clock.
• Lower the bead breaking arm by about 5 cm
(2 or 3 inches) to keep the upper bead of the
tyre inside the open centre during rotation.
• Rotate the tyre and make the necessary
adjustments until the upper bead has been
mounted.
• It may be useful to help the operation with
a second Run-Flat gripper and/or the bead
presser accessory, if available.
• Using the bead breaker disc, remove the Run-
