4.1 Demounting Tubeless Tires

A. Remove all wheel-weights from the rim.
Remove the valve stem or core and deflate the tire (Fig.
4.1-1).
NOTE: If the tire is over 13"(340 mm) wide, first set
the bead breaker in the "Wide" position as
follow:
1) Pull up and hold pin (1, Fig. 4.1-2), and pull the
bead breaker assembly in the "Wide" position.
2) Release pin (1, Fig. 4.1-2) in its hole to lock the
bead breaker in the new position.
b. Break both beads (Fig. 4.1-3).
Hold open the Bead Breaker, roll the tire/rim into the
Breaker area (Fig. 4.1-3). Ensure that the tire/rim
assembly is flat against the rubber breaker pads on
the side of the machine. Make certain that the bead
breaker blade is not over the top of any portion of the
rim. Now activate the bead breaker pedal. As soon as
the bead dislodges from the rim, release the breaker
foot pedal. It may be necessary to rotate the tire 90
degrees and repeat the above procedure to dislodge
all beads.
