Inflation
Tire inflation is performed in three steps: BEAD
SEAL, BEAD SEAT, and INFLATION. These steps are
explained in detail on page 12. Read the explanation of
each step and understand them thoroughly before pro-
ceeding.
Tire failure under pressure is hazardous.
This tire changer Will Not Restrain
Exploding Tires, rims or other related equip-
ment. Inspect tire and wheel carefully for
match, wear, damage, or defects before
mounting. Always use approved tire bead
lubricant during mounting and inflation.
The clip-on chuck allows the operator to
keep hands and entire body back from
inflating tire. The chuck must be an
open/freeflow style with all parts in proper
working order.
Check for proper inflation gauge operation.
Accurate pressure readings are important to
safe tire inflation. Refer to the Operating
Maintenance section of this manual for
instructions.
The inflation pedal, located at the center 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 should
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 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 tabletop for bead sealing.
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 tabletop.
The inflation pedal, located at the center of the left
side of the machine, controls the flow of air through
the inflation hose.
Note the Pedal Positions (See Diagram)
Use of bead sealing jets without a tire in
place can cause dirt and debris to be blown
into the air with enough force to injure
operator and/or bystander. Do not use the
bead sealing control position to inflate a
tire.
R. This 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 airflow 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 fol-
lowed 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 instruc-
tions. Check the function of the pressure limiter regu-
larly and maintain it according to the instructions
provided in this manual for safe and proper operation.
Do not tamper with or attempt to adjust the pressure
limiter. Tires requiring inflation beyond 60 PSI should
be inflated in a safety cage.
