9) Move to the outside of the tire and check the exact position of the hook visually and adjust it as needed. Then turn the spindle clock-
wise until the g-clamp is at the bottom (6 o’clock). The first bead will be mounted on the rim.
Remove the g-clamp.
Take the mobile control unit to work position D.
10) Remove the tool from the tire.
11) Move the tool carrier arm to its non-working position. Move it to the outside face of the tire.
12) Turn the tool 180° with lever (19,Fig. G).
13) Turn the spindle until the valve hole is at the bottom (6 o’clock).
14) Move the ramp (4 Fig. A) under the tire and lower the spindle until the tire is pressed down against the ramp . As the ramp is moved
slightly towards the outside, the tire will open a little and thus create enough space to insert the inner tube.
The valve hole may be asymmetrical to the centre of the rim. In this case position and insert the inner tube as shown in Fig. T.
Insert the valve through the hole and fix it with its locking ring.
15) Place the inner tube in the drop center of the rim (to facilitate this, turn the spindle clockwise).
Take the mobile control unit to work position B.

16) Turn the spindle until the valve is at the bottom (6 o’clock).
17) Inflate the inner tube a little (until it has no folds) so as not to pinch it while mounting the second bead.
18) Attach an extension to the valve and then remove the locking ring.
The purpose of this operation is to allow the valve to be loose so that it is not ripped out during second bead mounting.
19) Lift the tire again and attach the g-clamp outside the second bead about 8 inches (20 cm) to the right of the valve (See Fig. U).
20) Turn the spindle clockwise until the g-clamp is at 9 o’clock.
21) Move the tool carrier arm (14, Fig. D) to its working position.
22) Bring the tool forward until the red reference dot is lined up with the outside edge of the rim and about 1/4” (5 mm) from it.
23) Turn the spindle a little clockwise until you can insert the bead guide lever into its seating on the hook tool (See Fig. V). This lever
can be supplied on demand.
24) Pull back on this lever which will guide the bead into drop center. Continue to turn the spindle until the tire is completely mounted
on the rim.
25) Remove the g-clamp. Remove the hook tool by turning the spindle counterclockwise and moving it towards the outside.
26) Tip the tool carrier arm to its non-working position.
27) Position the ramp directly under the tire and lower the spindle until the tire rests on the ramp.
28) When the tire is resting on the ramp, 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.
29) Close the arms of the spindle completely. Support the tire to prevent it from falling off.
