Explosion Hazard

Never inflate
tire above
manufacturer's
recommended
pressure after bead is
seated.

Depress inflation pedal to position 2 and hold
about 1 second to begin air flow through tire
valve, then depress pedal to position 3 and hold
briefly – less than 1 full second. The blast of air
from the jets will expand tire and seal the beads.

Release the inflation pedal and allow it to return
to position 1. Verify that both beads are
completely sealed to the wheel. Repeat these
steps if beads have not sealed. It may be
necessary to wait a few seconds for the air
storage tank to recover before attempting again.

T. If tire and wheel are properly lubricated and
operator cannot achieve bead seal after 3 or 4
attempts, the valve core may 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.

Bead Seating

Operator should keep
hands, arms, and entire
body away from the tire

during the remaining bead seat and inflation
procedures. Do not stand over tire, as personal
injury could result.

NEVER increase air
pressure to exceed 40 PSI
when attempting Bead

Seat. If operator is unable to obtain Bead Seat,
something is wrong. Deflate tire completely,
inspect tire and wheel, correct any problems
found, relubricate both tire beads, and reattempt
Bead Seal and Seat procedures. Follow all safety
instructions in this manual and on machine.

Once tire pressure is indicated on the air gauge
(inflation pedal in position 1; foot removed from
pedal), continue to inject air into the tire in short
intervals. Check the pressure frequently. Stand
back during bead seat. Keep hands, arms, and
entire body away from tire during this procedure.

Tire beads should move outward and "pop" into
their bead seat position as pressure inside the
tire increases. If this does not happen, a
problem exists. Investigate carefully.

Check tire pressure
frequently. Never exceed
40 PSI while seating

beads. Once seated, never exceed tire
manufacturer's recommended air pressure. Tires
can explode, especially if they are inflated
beyond their limits. At all pressure levels when
inflating through the valve stem, keep hands,
arms, and entire body away from inflating tire.
An exploding tire, wheel, or bead sealing
equipment may propel upward and outward with
sufficient force to cause serious injury or death
to operator or bystander.

Inflation

NEVER exceed tire
m a n u f a c t u r e r ' s
recommended air

pressure. Tires can explode, especially if inflated
beyond these limits. Keep hands, arms, and
entire body back from inflating tire. Avoid
distraction during inflation. Check tire pressure
frequently to avoid over inflation. Excessive
pressure can cause tires to explode, causing
serious injury or death to operator or bystander.

Make sure both beads are seated. When both
beads are seated, the tire is ready for inflation.

Replace the valve core if it was removed.

Depress the inflation pedal to position 2 to
inflate the tire. The pressure limiter will cycle the
air flow as described earlier. On most passenger
car tires, the pressure limiter will cease air flow
at approximately 60 PSI. On smaller volume
tires the pressure may be higher.

U. Release air pressure from tire by pressing the
manual release valve button (inflation hose must be
attached to the valve stem, Figure 18).
