Place the wheel in a type approved device to ! nish
in" ating and completely settle the beads in their seats
on the rim.
Beading tubeless tires is sometimes di# 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 " oor in a
vertical position and ‘bounce’ it while introducing air with
the pedal control or with the In" ator Gauge (Figura 4.3-1).
Beading with the GP device:
The machine can be provided with a GP device, necessary
for bead seating of tubeless tires.
(Figure 4.3-2)
• If possible lock the wheel from inside. Outside locking
reduces e# ciency of the bead seater.
• Connect the compressed air hose to the valve (2).
• Lift the tire with both hands so that upper bead is sealed
to the rim edge (Fig. 4.3-2).
• Press the in" ation pedal (1) down swiftly. The top bead
is already sealed by the lifting motion. The air from the
bead seater jets will rebound into the bottom sidewall
driving it into place and creating a seal.
STOP THE COMPRESSED AIR AS SOON AS THE
BEADS GRIP THE RIM WELL.
• Place the wheel in a type approved cage to ! nish
in" ating and completely settle the beads in their seats on
the rim.

WARNING: WHEN OPERATING THE BEADING DEVICE
IT IS COMPULSORY TO WEAR EAR PROTECTION TO
PROTECT AGAINST NOISE AND SAFETY GOGGLES
TO PREVENT ANY CONTAMINATION BY DUST AND
OTHER IMPURITIES BLOWN BY THE AIR JETS.
