COATS Pit Tire Changer - Manual (Page 14)

10 • Important: Always read and follow the operating instructions.
Bead Sealing
1. Position valve stem in front of operator and con-
nect the inflation hose with the clip-on chuck. Be sure
tire’s top bead does not cover the bottom of the valve
stem
2. Depress inflation pedal to position 2 and hold
about five seconds to begin air flow through tire valve.
3. Release the inflation pedal and allow it to return to
position 1. Verify that 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 pressure to recover before
attempting again.
S. If tire and wheel are properly lubricated and
operator cannot achieve bead seal after three
or four 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 clip-on
chuck and reinstall the valve core. Reattach the
clip-on chuck after core is installed.
Bead Seating
NEVER exceed 40 PSI to seat beads while
using this tire changer. If more than 40 PSI is
permitted by tire manufacturer, ALWAYS use
safety cage and clip-on chuck. NEVER
exceed recommended pressure after seat-
ing beads. ALWAYS keep hands and entire
body back from inflating tire.
An exploding tire, wheel, or bead sealing
equipment may propel upward and out-
ward with sufficient force to cause serious
injury or death to operator or bystander.
Check tire pressure frequently. 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 (inflation pedal posi-
tion 2) in short intervals. Check the pressure fre-
quently. Stand back during bead seat. Keep hands,
arms, and entire body away from tire during this pro-
cedure.
Inflation
NEVER exceed tire manufacturer's recom-
mended air pressure. Tires can explode,
especially if inflated beyond these limits.
Use clip-on air chuck, keep hands, arms and
entire body back from inflating tire. Avoid
distraction during inflation. Check tire pres-
sure 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.
