IMPORTANT SAFETY INSTRUCTIONS
Read and follow all caution and warning labels affixed to equipment and tools.
Read and understand all instructions before operating this machine.
Misuse of this equipment can cause personal injury and shorten the life of the Tire
Changer.
To prevent accidents or damage to the Tire Changer, use only Hunter recommended
procedures and accessories.
Wear OSHA approved eye protection while operating the Tire Changer.
Wear non-slip safety footwear when operating the Tire Changer.
Do not wear jewelry or loose clothing when operating theTire Changer.
Wear proper back support when lifting or removing wheel from the Tire Changer.
Never stand on theTire Changer.
WARNING: Keep hands and clothing clear of moving parts. Keep
hands clear of upper roller when bead loosening or
rotating clamped wheel. Do not lean or reach over tire
when inflating.
WARNING: Do not exceed these pressure limitations:
SUPPLY LINE PRESSURE (from compressor) 175 PSI.
OPERATING PRESSURE (gauge on regulator) 115 PSI.
BEAD SEATING PRESSURE (gauge on hose) 40 PSI.
WARNING: Never mount a tire to a rim that is not the same diameter
(e.g., 16 1/2 inch tire mounting on a 16 inch rim).
WARNING: After loss of air line pressure ALWAYS raise the wheel
lift pedal to prevent the wheel lift from rising quickly
during first operation.
DANGER: Activate blast inflation nozzle only when seating bead.
CAUTION: Do not hose down or power wash electric tire changers.
Bleed air pressure from system before disconnecting supply line or other pneumatic
components. Air is stored in a reservoir for operation of the blast inflation nozzle. Air
pressure can be bled from the system by pulling up on the knob located on top of the
regulator, and then turning it counterclockwise.
Do not activate the blast inflation nozzle if the tire is not properly clamped.
Do not operate Tire Changer with worn rubber or plastic parts.
Wheels equipped with low tire pressure sensors or special tire and rim design may
require certain procedures. Consult manufacturer’s service manuals.

Electrical
The Tire Changer is manufactured to operate at a specific voltage and amperage
rating.
Make sure that the appropriate electrical supply circuit is of the same voltage and
amperage ratings as marked on the Tire Changer.
WARNING: DO NOT ALTER THE ELECTRICAL PLUG. Plugging the
electrical plug into an unsuitable supply circuit will
damage the equipment.
Make sure that the electrical supply circuit and the appropriate receptacle is installed
with proper grounding.
To prevent the possibility of electrical shock injury or damage to the equipment when
servicing the Tire Changer, power must be disconnected by removing the power cord
from the electrical power outlet.
After servicing, be sure the Tire Changer ON/OFF switch is in the “O” (off) position
before plugging the power cord into the electrical power outlet.
Specific Precautions/Power Source
The Tire Changer is intended to operate from a power source that will apply 208-
230VAC, 1 phase, 15 amp 50/60 Hz, power cable includes NEMA 20 amp plug, L6-
20P, between the supply conductors of the power cord. The power cord supplied
utilizes a twist lock connector, NEMA L6-20P. This machine must be connected to a
20 amp branch circuit. Please refer all power source issues to a certified electrician.
Refer to “Installation Instructions for Tire Changer.
CAUTION: A protective ground connection, through the grounding
conductor in the power cord, is essential for safe operation.
Use only a power cord that is in good condition.
Turning Power ON/OFF
The ON/OFF switch is located on the back of the Tire Changer. To turn the Tire
Changer “ON,” press the “I” side of the ON/OFF switch. To turn the Tire Changer
“OFF,” press the “O” side of the ON/OFF switch.
IMPORTANT: After turning on the Tire Changer the user must wait 30 seconds for the
motor controller to “learn” the position of the rotation pedal before operating
the tire changer.
Re-starting
If a rotation issue is encountered, re-start the tire changer using the following
procedure:
1. Switch the tire changer power switch to the “off” position.

6 •
••
•Getting Started TCA34R Series Changer Operation Instructions
2. Wait 1 minute to discharge the drive system.
OR
Lift the rotation pedal (reverse) to discharge the drive system.
3. Do NOT touch the rotation pedal for 30 seconds. This will allow the pedal to
“learn” its new position.
4. Operate the tire changer normally.
Equipment Installation and Service
A factory-authorized representative should perform installation.
This equipment contains no user serviceable parts. All repairs must be referred to a
qualified Hunter Service Representative.

1.3 Wheel Lift Pedal
Press down on the wheel lift pedal to raise wheel lift. When the pedal is released the
wheel lift will lower.
CAUTION: The wheel lift may rise quickly during the first operation after
loss of air line pressure. This can be mitigated by first lifting
on wheel lift pedal before pressing down to operate wheel lift.
1.4 Wheel Rotation Pedal
The middle pedal on the Tire Changer base controls the rotation of the wheel. Refer
to “Equipment Components,” on page 9.
Step down on the pedal to rotate the wheel clockwise (variable speed).
Lift the pedal to rotate the wheel counterclockwise (fixed speed).
CAUTION: Keep hands clear of wheel, tire, and rollers during bead
loosening.
1.5 Air Inflation Pedal
The right-hand pedal on the Tire Changer base is a two-stage design. Refer to
“Equipment Components,” on page 9. The pedal controls the air going to the inflation
hose and the blast inflation nozzle.
CAUTION: Keep hands clear of wheel during sealing and seating of
bead.
CAUTION: When operating air inflation hose, do not lean over the tire.
Step down partially on the pedal to inflate tires through inflation hose.
Step down completely on the pedal to activate the blast inflator nozzle to seal tire
beads.
Refer to “2.8” on page 27 for complete inflation operation instructions.

8 •
••
•Getting Started TCA34R Series Changer Operation Instructions
1.6 Inflator and Pressure Limiter
As a safety device, the pressure limiter prevents the operator from using excessive
air pressure to seat the tire bead during tire inflation. Bead seating pressure should
never exceed 60 psi. If tires being mounted require more than 60 psi for inflation
pressure, the tire/wheel assembly should be removed from the tire changer, placed in
an inflation cage, and inflated per manufacturer’s instructions.
While inflating the tire, the pressure gauge will read zero until the inflation pedal is
released. At that time, the gauge will give the correct air pressure reading in the tire.
Refer to “2.8” on page 27 for complete inflation operation instructions.
1.7 Bead Press Arm
The bead press arm assists with tire mounting. The bead press arm moves in tandem
with the mount / demount head.
The controls on the bead press arm move the bead press up or down.
Refer to “Equipment Components,” on page 9.
1.8 Push Button Controls
The command unit governs all the movements necessary for complete bead roller
and tire tool operation. Refer to “Equipment Components,” on page 9.
The command unit is used to position both of the bead rollers and the tool head/ bead
press arm assembly independently. The manual controls are used in special
applications, such as PAX tires and wheels.

Tool Head Damage Prevention
NOTE: Always generously GREASE all
sides, including the bottom, of new
tool heads with tire lube paste
before first use.
If the tool head breaks near the middle the user was rotating the wheel and tire
assembly while pressing the “Tool Head Raise” button.
Use the following tips to prevent this type of tool head damage:
•DO NOT ROTATE while pressing the “Tool Head Raise” button.
•Ensure tool head cradles the rim edge before rotating during demount of
upper bead.

If the tool head breaks at the mount/demount end the tire bead was not in the drop
center when mounting the upper bead.
Use the following tips to prevent this type of tool head damage:
•The bead MUST be in the drop center when mounting the upper bead.
•Use the bead press device and the upper roller to guide the bead into the
drop center.
•Ensure the bead is completely in the drop center on wheels where the
drop center is far from the bead seat.

2.1 Placing Wheel on TC
Wheel Support Plate Height Adjustment
The wheel support plate on the TC is height adjustable to allow a wide range of
wheels to be serviced.
Use the highest setting for most high offset wheels.
Standard wheels typically use the middle height.
Use the lowest height for most reverse drop-center wheels.
To adjust center support height, pull the knob outwards on center support and raise or
lower center support table to desired height.
