COATS 5035 A/E Tire Changer - Manual (Page 9)

INFLATION
Tire inflation is performed in three steps: Bead Seal,
Bead Seat, and Inflation. These steps are explained
in detail on page 13. Read the explanation of each
step and understand them thoroughly before
proceeding.
Check for proper infla-
tion gauge operation.
Accurate pressure
readings are important to safe tire inflation.
Refer to the Operating Maintenance section of
this manual for instructions.
If the rim has been
clamped from the out-
side for tire mounting,
release the clamps, lift the tire, and move the
clamps to the center of the table top.
If the wheel/tire has a
diameter larger than
14 inches and is diffi-
cult to bead seal, the clamps should be moved
to the center of the table top for the bead seal
operation.
Tire failure under pres-
sure is hazardous. This
tire changer is not
intended to be a safety device to contain explod-
ing tires, tubes, wheels, or bead sealing equip-
ment. 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, 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.
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 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 this position
without a tire and wheel positioned on the table
top. Dirt and debris could be blown into the air with
enough force to injure the operator or bystanders.
Do not use the position to inflate a tire.
IMPORTANT: The unit is equipped with a pressure
limiter to assist the operator with proper tire inflation.
When the inflation pedal is held in position 2, the
pressure limiter cycles the machine between
position 2 (inflation) and position 1 (at rest, no air
flow to tire). This cycling helps to prevent over
inflation of the tire. Tires can still be over inflated
and explode with the use of this pressure limiter if all
of the instructions in this manual are not followed
completely. The pressure limiter will keep most car
and light truck tires from inflating beyond 60 PSI
(smaller tires may reach higher pressures). It is the
operator's responsibility to follow all instructions and
to control inflation pressure as specified in these
instructions. Check the function of the pressure
limiter regularly and maintain it according to the
instructions provided in this manual for safe and
proper operation. Tires that require inflation beyond
60 PSI should be inflated in a safety cage.
Bead Sealing
1. Connect the inflation hose to the tire valve stem.
Hold the tire up against the upper edge of the
wheel. Be sure the top bead of the tire is over
the bottom of the valve stem (Figure 15).
