COATS RC150EX, RC200EX Tire Changer - Manual (Page 18)

14 • Important: Always read and follow operating instructions.
Bead Sealing
1. Position valve stem in front of operator and con-
nect the inflation hose with the clip-on chuck. Hold
tire up against upper edge of the wheel. Be sure tire’s
top bead does not cover the bottom of the valve stem
(figure 16).

2. Depress inflation pedal to position 2 and hold about
one second to begin air flow through tire valve, then
depress pedal to position 3 and hold briefly — less than
one 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 pressure to recover before attempt-
ing 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 seating
beads. ALWAYS keep hands and entire body
back 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.
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, relu-
bricate 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 frequently.
Stand back during bead seat. Keep hands, arms, and
entire body away from tire during this procedure (figure
17).
