30. Remove the clip. Remove the hook tool by turning the spindle anticlockwise and moving it towards the outside.
31. Tip the tool carrier arm to its non‐working position.
32. Position the platform directly under the wheel and lower the spindle until the wheel rests on the platform.
33. Take the mobile control unit to work position B.
34. 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.
35. Close the arms of the spindle completely. Support the wheel to prevent it falling off.
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.
36. Move the platform to release the wheel from the spindle.
37. Remove the wheel.

Turn the turntable and advance the bead breaker disk with small forward movements following the side ring
profile until the first bead is completely detached.
N.B.: lubricate during this operation.
For wheels with an inner tube, be extremely carefully when stopping the bead breaker
disk from moving forward immediately after bead is detached to prevent damaging the
valve and the inner tube.
6.
Repeat the operation, making the bead breaker disk move forward against the side ring (See picture F13.25)
until the locking ring is freed, which will be removed using the side ring lever or with the help of the bead breaker
disk.
