TYRE MOUNTING WITH THE DISK
Follow these steps:
1) If the rim has been removed from the spindle, put it back on the spindle as described in the section on “CLAMPING THE WHEEL”.
2) Lubricate both beads and the rim with tire manufacturer recommended lubricant.
3) Attach the g-clamp to the outside edge of the rim at the highest point (See Fig. M).
CAUTION!
Make sure the g-clamp is firmly attached to the rim.
Take the mobile control unit to work position B.
4) Put the tire on the platform and lower the spindle (make sure the g-clamp is at the high point).
5) Lift the rim with the tire hook to it and turn it anticlockwise about 6-8 inches (15-20 cm.) The tire will be positioned tilted across the
rim.

6) Position the bead loosener disk against the second bead of the tire and turn the spindle until the clip is at the low point (at 6
o’clock).
7) Move the disk away from the wheel.
8) Remove the clip and replace it at 6 o’clock outside the second bead (See Fig. N).
9) Turn the spindle clockwise 90° to bring the clip to 9 o’clock.
10) Move the disk forward until it is about 0,5-1 inch (1-2 cm) inside the edge of the rim. Begin to turn the spindle clockwise checking to
make sure that, with a 90° turn, the second bead begins to slip into the centre well.
11) When the bead is fully mounted, move the tool away from the wheel, tip it to its non-working position and remove the clip.
12) Position the platform under the wheel, lower the spindle until the wheel rests on the platform.
Take the mobile control unit to work position C.
13) Close the arms of the spindle completely. Support the wheel to prevent it falling off.
DANGER!
Potentially hazardous operation!
Do it manually only if you are certain you can keep the tire assembly balanced. For large and heavy tires
14) Move the ramp to remove the tire assembly from the spindle.
15) Remove the tire assembly.
NB: 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.
Take the mobile control unit to work position B.
