COATS 5035 A/E Tire Changer - Manual (Page 10)

2. Depress the inflation pedal to position 2 and
hold about 1 second to begin air flow, then
depress pedal to position 3 and hold very briefly
– less than 1 full second. The blast of air from
the jets will expand the tire and seal the beads.
3. Remove your foot from 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.
NOTE: If tire and wheel are properly lubricated and
the operator cannot achieve bead seal after 3 or 4
attempts, the valve core may be removed from the
valve stem to allow more air 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 both the tire and wheel,
correct any problems found, relubricate both tire
beads, and reattempt Bead Seal and Bead 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 limiter pressure may be higher.
NOTE: Release air pressure from the tire by
pressing the manual release valve button (inflation
hose must be attached to the valve stem).
