-Always keep the rotating counterclockwise, while pushing with the bead disk.
Turn the wheel counterclockwise pushing with disk until the tire comes completely off the rim.
DANGER!
When the beads come off the rim, the tire will fall. Check to make sure there are no by-standers in the work
area.
MOUNTING
Tubeless tires can be mounted using either the bead loosener disk or the hook tool. If the tire is not problematic, use the bead loosener
disk. If the tire is very rigid, the hook tool must be used.
TIRE 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 “RIM CLAMPING”.
2) Lubricate both beads and the rim with tyre 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 hooked to it and turn it anticlockwise about 6-8 inches (15-20 cm). The tyre will be positioned included across
the rim.
Take the mobile control unit to work position B.
