• Refit the valve sensor (if removed).
• Lubricate both tyre beads.
• Place the sensor at 5 or 6 o'clock.
• Set the tyre at an angle of about 45 degrees
• 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-Flat grippers used.
• Connect the inflation line to the valve for bead insertion.
CORRECT PROCEDURE FOR DEmOUNTING/mOUNTING
RUN FLAT TYRES WITH STRAP-ON SENSOR
NB: the sensor is at 180° to the tyre valve.
• Remove the valve plunger and let all the air out of the tyre.
• Visually inspect the actual position of the sensor that should be at 180°.
• Place the sensor at 3 o'clock (valve at 9 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
(valve at 6 o'clock) and not beyond.
• Raise the bead breaker disc.
• Move the sensor to 6 o'clock (valve at 12 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 – valve at 12 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 – valve at 4 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.
• Lubricate both tyre beads.
• Place the sensor at 2 or 3 o'clock (valve at 8 o'clock)
• Set the tyre at an angle of about 45 degrees
• Turn the tyre so that it touches the mounting head and starts to be mounted on the rim.
• Turn the tyre until the lower bead is mounted.
• Turn the sensor to 4 or 5 o'clock (valve at 10 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.
