Beading Tubeless tires:
Perform the beading with the wheel blocked on the
tire changer.
• Ensure that both the beads and the inside of the
rim are thoroughly lubricated.
• Screw the valve insert.
• Connect the compressed air hose to the valve
(1,Figure 5.3-1).
• Operate the compressed air to ensure the beads
are seated.
STOP THE COMPRESSED AIR AS SOON AS THE
BEADS GRIP THE RIM WELL.
• Place the wheel in a type approved cage to fi nish
infl ating and completely settle the beads in their
seats on the rim.
Beading tubeless tires is sometimes diffi cult because
the beads may be very close together (e.g. owing to
incorrect stacking) and so fail to seal against the rim
properly.In this event it may be helpful to place the
wheel on the fl oor in a vertical position and 'bounce'
it while introducing air with the pedal control or with
the nozzle (Figura 5.3-2).
Beading with the GP device:
The machine can be provided with a GP device,
necessary for bead seating of tubeless tires.
• Connect the compressed air hose to the valve
(1,Figure 5.3-1).
• Position the GP device beading nozzle between
tire and rim, pointing the air jet inside the tire
(2,Figure 5.3-1).
• Quickly press the beading pedal down all the
way. A high pressure air jet is expelled from the
injector nozzle and the beads adhere to the edge
of the rim, at the same time the infl ation of the tire
continues via the valve.
STOP THE COMPRESSED AIR AS SOON AS THE
BEADS GRIP THE RIM WELL.
• Place the wheel in a type approved cage to fi nish
infl ating and completely settle the beads in their
seats on the rim.
