3.
Inspect the valve stem and replace if necessary.
Next lubricate the tire beads liberally with tire manufac-
turer’s approved rubber lubricant (fi gure 16).
Figure 16 - Lubricate Tire Beads Liberally
4.
Place tire over wheel and move tower arm into
position. Position tire so that the lower bead is above
the rear extension of the Duckhead® mount/demount
tool and below the front knob (fi gure 17).

5.
Depress tabletop pedal and rotate the wheel to
mount the lower bead. Use the drop center of the
wheel by forcing down on the tire just ahead of the
mounting tool and follow as the tire rotates (fi gure 18).
Rotate the tabletop until the lower bead is mounted.

6.
For top bead installation, rotate the tabletop until
the valve stem on the wheel is 90 degrees ahead of
the Duckhead tool (at the 3 o’clock position). Lift the
upper bead of the tire up and over the rear of the Duck-
head tool. With your hand or using the power roller,
press down on the tire sidewall between the Duckhead
tool and the valve stem to hold the tire in the rim drop
center. The bead should also be under the right side
of the knob on the Duckhead tool (fi gure 19). Depress
the tabletop pedal and rotate the tire until the bead is
mounted. Be careful to assure the bead stays in the
rim drop center in the area ahead of the Duckhead tool.

Note
If tabletop rotation stalls, reverse the tabletop
momentarily until the tire bead is again loose on the
wheel. Reposition the tire on the Duckhead tool, make
sure the bead is correctly positioned in the drop center
of the wheel; then attempt mounting again.
Note
For tube type tires, mount the lower bead fi rst,
move the tower back, install the tube, and then mount
the upper bead.
