Operations
Beading Tubeless: tires
Perform the beading with the wheel blocked on the
tire changer.
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 5.4-0).
Beading with the GT device:
The machine can be provided with a GT device,
necessary for bead seating of tubeless tires.
• Connect the compressed air hose to the valve
(Figure 5.4-1).
• Position the GT device beading nozzle between tire
and rim, pointing the air jet inside the tire (Figure
5.4-1).
• Press the key on the Tubeless Beading Nozzle (4,
Abb.5.4-2), then press the pedal all the way down
decisively (1, Abb.5.4-2). 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.
