COATS RC-100 Tire Changer - Manual (Page 12)

8 • Important: Always read and follow operating instructions.
Inflation
On the RC100, tire inflation is performed in two steps:
Bead Seat and Inflation. These steps are explained in
detail on page 10-11. Read the explanation of each step
and understand them thoroughly before proceeding.
CAUTION
Check for proper inflation gauge operation.
Accurate pressure readings are important
to safe tire inflation. Refer to the Operat-
ing Maintenance section of this manual for
instructions.
CAUTION
If the rim has been clamped from the outside
for tire mounting, release the clamps, lift the
tire, and move the clamps to the center of
the table top.
DANGER
Tire failure under pressure is hazardous. This
tire changer is not intended to be a safety
device to contain exploding tires, tubes,
wheels, or bead sealing equipment. Inspect
tire and wheel carefully for match, wear,
or defects before mounting. Always use
approved tire bead lubricant during mount-
ing and inflation.
The inflation pedal, located at the rear of the left side
of the machine, controls the flow of air through the
inflation hose.
NOTE: The clip-on chuck on the end of the hose
should always be an open style with all parts in
proper working order.
Position 1 - At Rest – With the inflation hose attached
to the tire valve and the pedal in this position, the air
gauge will register the air pressure in the tire. Whenever
your foot is removed from the pedal, it will return to this
position.
Position 2 - Tire Inflation – This is the first activated
position. With the inflation hose attached to the tire
valve and the pedal in this position, line pressure is
allowed to flow through the valve and into the tire for
inflation. Tire pressure is not indicated on the gauge in
this position.
Bead Seating
WARNING
Operator should keep hands, arms, and
entire body away from the tire during the
remaining bead seat and inflation proce-
dures. Do not stand over tire, as personal
injury could result.
WARNING
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 reat-
tempt 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.
WARNING
Check tire pressure frequently. Never exceed
40 PSI while seating beads. Once seated,
never exceed tire manufacturer’s recom-
mended 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.
