Connect inflation hose to valve stem.
Pull up on the tire lightly to reduce the gap between upper bead and the rim.
Do not stand over tire during inflation.
Step down completely on the air inflation pedal (pedal on the left side of the base) to release
a high-pressure air blast through jets on the clamps to assist in seating the beads of the tire.

To increase the effectiveness of the inflation jets, always liberally lubricate beads
and raise the lower bead while activating inflation jets.
