Explosion Hazard
Never inflate
tire above
manufacturer's
recommended
pressure after bead is
seated.
2. 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.
3. 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.
S. 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.
1. 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.
1. Make sure both beads are seated. When both
beads are seated, the tire is ready for inflation.
2. Replace the valve core if it was removed.
3. 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.
T. Release air pressure from tire by pressing the
manual release valve button (inflation hose must be
attached to the valve stem, Figure 19).

DANGER
IMPORTANT: When inflating tires that require more than 60 PSI, always use a safety cage and air hose with a
clip-on air chuck and in-line valve. The hose must have enough length between the chuck and the operation/in-
line valve to allow the operator to stand outside the trajectory.
