2. Step on the inflation pedal to allow air to flow into the tire

and seal the beads. (see Fig 14.8)

TO SEAL LOW PROFILE OR DIF-

FICULT BEADS, USE THE TURBO

BLAST TO SEAL THE BEAD

1. To Open the Slide Valve, PUSH the Slide Valve Forward.

2. To Close PULL the Slide Valve closed. (See Fig 14.10)

3. Position the Turbo-Blast Nozzle to direct air towards

the Rim Center just under the Rim lip. (See Fig. 14.11)

4. Depress inflation pedal and open the Turbo-Blast Valve

for less than one full second. The blast of air from the Turbo

Blat Nozzle will expand tire and seal the beads.

5. Repeat these steps if beads have not sealed. It will be

necessary to wait a few seconds for the air storage tank to

recover before attempting again. If tire and wheel are properly

lubricated and operator cannot achieve bead seal after a few

attempts, check to see if the valve core has been be removed

from the valve stem to allow more air flow into the tire to assist

with bead seal. After bead seal is achieved, remove the chuck

and reinstall the valve core.

STAGE THREE / BEAD SEATING

Bead seating usually occurs on the long tapered side of the

wheel first and the shorter side last. Bead seating will

usually require at least 7 PSI in the tire. 40 PSI is the

maximum safe pressure at this stage regardless of tire

operating pressure. Most European import cars and many

aftermarket alloy wheels are very tight and can be difficult

to bead seat. Also note that asymmetrical hump and run-flat

tires are extremely difficult to bead seat. Follow tire

manufacturer’s recommended procedure for bead seating.
