COATS 5030 A/E Tire Changer - Manual (Page 11)

Important: Always read and follow operating instructions. • 7
WARNING
Do not force the tire onto the rim. Bead dam-
age could result making the tire unsafe and/
or creating the risk of injury.
NOTE: If table top rotation stalls, reverse the table top
momentarily until the tire bead is again loose on the
wheel. Reposition the mount tool, make sure the bead
is correctly positioned in the drop center of the wheel,
then attempt mounting again.
NOTE: For low profile or stiff sidewall tires, it may be
advantageous to use the bead lifting tool to initially hold
the upper bead down in the drop center, or use drop
center tools as shown in Figure 30.
NOTE: For tube type tires, mount the lower bead first,
move swing arm out, install the tube, and then mount
the upper bead.
Inflation
Tire inflation is performed in three steps: Bead Seal,
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.
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.
CAUTION
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 (small 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.
