8. Place the helper foot opposite the demount head and push
the bead into drop center. Insert bead lifting tool between knob
on demount tool and tire bead (Figure 10). Use roller tool to pro-
vide clearance.
9. Rotate lifting tool down over wheel to lift bead up and over
the knob and at the same time remove helper foot (Figure 11).
10. Hold lifting tool in place, depress the table top rotation
pedal momentarily to jog the wheel a short distance. Check the
wheel and tire to verify that operation is not causing damage. The
lifting tool can usually be removed after jogging the wheel a short
distance (Figure 12). Continue to jog the wheel to allow the tire
sidewall to flex as it crosses the rim edge. Continue short rota-
tions until top bead is completely demounted.
11. Demount lower bead. In most cases when demounting
performance tires, the lower bead will be less difficult. Pay close
attention to sensor/transmitter location, and position it just
before the demount tool when starting the lower bead demount
procedure (Figure 13).
12. Use the upper side of the helper foot to hold the bead in
drop center while lifting the lower bead over the demount tool
(Figure 14). Hold the lifting tool in place and remove the helper
foot. Depress the table top rotation pedal momentarily to jog the
wheel short distances to complete the demounting process.
