10. Hold lifting tool in place, depress the table top
rotation pedal momentarily to jog the wheel a short dis-
tance. 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.
Continue to jog the wheel to allow the tire sidewall to
flex as it crosses the rim edge. Continue short rotations
until top bead is completely demounted (figure 38).

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 (fig-
ure 39).

distances to complete the demounting process.
