8. Demount lower bead. Pay close attention to sen-
sor/transmitter location, and position it just before the
mount/demount tool when starting the lower bead
demount procedure (Figure 30).
Figure 30 - Sensor/Transmitter Location
9. Lift and hold the tire at an angle so the lower
bead is resting in the drop center directly across
from the mount/demount tool, and is loose below the
mount/demount tool. Insert bead lifting tool down
over mount/demount tool and below the lower bead.
Lift the lower bead over the mount/demount tool (Fig-
ure 31). Hold the bead lifting tool in place. Depress the
table top rotation pedal momentarily to jog the wheel
short distances to complete the demounting process.

Mounting (using Robo-Assist™ Helper Arm)
1. Lubricate both tire beads liberally. Performance
tires will require more lubrication than standard pas-
senger car tires.
2. Mount the lower bead. In most cases, the lower
bead will mount easily.
Mounting the top bead can be very dicult
when mounting new tires on performance and
custom wheels. Proceed slowly and cautiously.
3. Position the valve stem 90 degrees clockwise in
front of the mount/demount tool for top bead mount-
ing. Lift the bead over the rear tail of the mount/
demount tool. Use the Robo-Assist™ helper arm to
hold the bead in the drop center (Figure 32). Rotate
the wheel in short steps and apply extra lubricant to
mount upper tire bead.

4. On extremely tight tire and wheel combinations, it
may be necessary to use the bottom of the assist foot
to flip the tire bead over the rim flange (Figure 33)
