14) Move the ramp to remove the tire assembly from the spindle.
15) Remove the tire assembly.
If the tire permits it, the operation described above can be speeded up by mounting both beads at the same time:
- Follow the steps described under points 1,2,3,4 described above but instead of attaching the g-clamp to just the first bead (refer to
point 4) clip it to both.
- Lift the rim with the tire hooked to it and turn it counterclockwise 6-8 inches (15-20 cm) (clip at 10 o’clock).
- Follow the steps described in points 10,11,12,13,14,15 above.

MOUNTING WITH THE HOOKED TOOL
1) Follow the steps described in points 1,2,3,4,5 for mounting with the disk.
2) Move the tool carrier arm to its non-working position. Move it to the inside face of the tire and rehook it at this position.
3) Check to make sure the hook tool is positioned facing the tire bead. If not, press lever (19, Fig. G) and turn it 180°.
Take the mobile control unit to work position D.
4) Move the tool forward until the red reference dot is lined up with the outside edge of the rim and about 1/4 inches (5 mm) from it
(See Fig. O).
5) Move to the outside of the tire assembly and check the exact position of the hook visually and adjust it as needed. Then turn the
spindle clockwise until the g-clamp is at the bottom (6 o’clock). The first bead will be mounted on the rim.
6) Remove the g-clamp.
Take the mobile control unit to work position D.
7) Remove the tool from the tire.
8) Move the tool carrier arm to its non-working position. Move it to the outside face of the tire and rehook it in this position.
9) Turn the tool 180° with lever (19, Fig. G).
10) Attach the g-clamp at the bottom (6 o’clock) outside the second bead (See Fig. N).
Take the mobile control unit to work position C.
11) Turn the spindle counterclockwise to about 90° (clip at 9 o’clock).
12) Bring the tool forward until the red reference dot is lined up with the outside edge of the rim and about 1/4 inches (5 mm) from it.
Begin to turn the spindle counterclockwise and check if, after about 90° of rotation the second bead has started to slip into the drop
center. Continue turning until the g-clamp is at the bottom (6 o’clock). The second bead will now be mounted on the rim.
13) Follow the steps described in points 11, 12, 13, 14, 15 for mounting with the disk, since this will ensure that the tire assembly is removed
correctly from the machine.
Take the mobile control unit to work position C.
