COATS 7xxx Series Tire Changer - Manual (Page 14)

10 • Important: Always read and follow operating instructions.
Infl ation
Tire inflation is performed in three steps: BEAD SEAL,
BEAD SEAT, and INFLATION. These steps are explained
in detail on page 14. Read the explanation of each step
and understand them thoroughly before proceeding.
DANGER
Tire failure under pressure is hazardous.
This tire changer Will Not Restrain Explod-
ing Tires, rims or other related equipment.
Inspect tire and wheel carefully for match,
wear, damage, or defects before mounting.
Always use approved tire bead lubricant
during mounting and inflation.
CAUTION
The clip-on chuck allows the operator to
keep hands and entire body back from inflat-
ing tire. The chuck must be an open/freeflow
style with all parts in proper working order.
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.
CAUTION
If the wheel/tire has a diameter larger than
14-inches and is difficult to bead seal, the
clamps should be moved to the center of the
table top for the bead seal operation.
The inflation pedal, located at the rear of the left side
of the machine, controls the flow of air through the
inflation hose, and has three positions.
Note: The clip-on chuck on the end of the hose is a
safety item that must always be an open/freeflow style
with all parts in proper working order.
Position 1 - Tire Pressure – 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 (using the
clip-on chuck) to the tire valve and the pedal in this
position, line pressure is allowed to flow through the
valve system and into the tire for inflation. Correct tire
pressure is not indicated on the gauge in this position.
Position 3 - Bead Sealing – This is the second and
last activated position. With the inflation hose attached
to the tire valve and the pedal in this position, line pres-
sure is allowed to flow through the valve and to the
air-flate bead seal jets on the table top for bead sealing.
Note: Some models use a single-point nozzle bead
sealer.
1. 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.
