COATS Extended Mobility (EMT) RunFlat Tires - Manual (Page 23)

The Objective of this Section:
To demonstrate the safe and proper bead seal, bead seat, and inflation of exceptionally stiff
sidewall tires.
Safety Issues Related to this Section:
• ALWAYS wear eye protection during tire service activity.
• ALWAYS wear durable work clothing (i.e.; tight-fitting leather gloves, steel-toed shoes, back belts).
• NEVER wear loose fitting clothing or articles, jewelry, or long hair.
• NEVER exceed the maximum safe air pressure during inflation process.
Tire inflation is performed in three (3) steps: bead seal, beat
seat, and inflation. These steps are explained in detail on
page H–5. Read the explanation of each step and understand
them thoroughly before proceeding.
Make sure the tire changer inflation gauge is opera-
tional. Accurate tire pressure readings are important to
safe tire inflation. Do not use a hand held gauge as per-
sonal injury could result.
If the wheel has been clamped from the outside for tire
mounting, release the clamps, lift the tire, and move the
clamps to the center of the tabletop.
If the tire/wheel has a diameter larger than 14 inches and
it is difficult to bead seal, the clamps should be moved to
the center of the tabletop for the bead seal operation.
Tire failure under pressure is hazardous. The 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
mounting and inflation.
The inflation pedal controls the flow of air through the infla-
tion 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 the operator’s
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.
Position 3–Bead Sealing–This is the second and last activat-
ed 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 to the air-flate bead seal jets on the
table top for bead sealing.
Use Position 3 for bead sealing only. Do not use position
3 without a tire and wheel positioned on the tabletop.
Dirt and debris could be blown into the air with enough
force to injure the operator or bystanders. Do not use posi-
tion 3 to inflate a tire.
