1. Rotate the wheel and lubricate the entire cir-
cumference of the upper bead of the tire and
wheel.
2. Make sure to adequately lubricate the hori-
zontal wheel surface above the drop center
and below the safety hump.
3. Move the swing arm into position. Adjust the
duckhead so that it rests against the wheel.
4. Rotate the wheel until the valve stem is
opposite the duckhead and the sensor is under
the rear portion of the duckhead. Lubricate and
insert the lift bar between the tire and wheel
under the front extension of the duckhead.
5. Begin rotating the lift bar down over the
duckhead to pull the tire bead up and over the
duckhead. Remove the drop center tool (or
other aid) as the bead slides into the drop cen-
ter of the wheel.
6. Continue to pull the lift bar down and lift the
tire bead onto the duckhead.
7. Hold the lift bar down against the wheel.
8. Rotate the wheel until the upper bead is free
of the wheel.
9. Rotate the wheel until the sensor is once
again under the duck head. Lift the tire and
carefully guide the lower bead into position
above the sensor.
10. Use the lift bar to lift the lower bead over
the duck head.
11. Rotate-pause-rotate the wheel until the
lower bead is free of the wheel.
