NOTE: This procedure should be performed only by an authorized factory
representative.
Read and become familiar with these instructions before starting installation.
WARNING: Read and follow all caution and warning labels affixed to your
equipment and tools. Misuse of this equipment can cause personal
injury and shorten the life of the tire changer.
Placement
The TCA28 should be placed in a dry area which is not subjected to water spray.
The TCA28 is best positioned with the back of the unit against a wall. Clearance for the operator at the front and
left of the tire changer should be at least 3 feet. There must also be ample clearance to the right of the tire
changer to allow the bead breaking arm to fully extend. Workspace and operating dimensions are shown below.
The electrical power cord and air hose should be positioned so that it cannot be walked on, driven over, or tripped
over.

Floor Requirements
The tire changer should be placed on a solid concrete floor. Any floor condition which might allow the tire changer
to move during operation is unacceptable. The depth of the flooring must guarantee anchor bolts will hold firmly.
If the location selected is a cement floor that is hollow underneath, place the tire changer over a supporting beam
or close to a supporting wall.
Power Requirements
The customer must furnish 230VAC, 60 HZ, service for maximum 12 AMP draw, single-phase power for the
TCA28.
Power source requirements of TCA28 are located on the Hunter serial number plate.
Changes to the AC power cord, plug and/or power source must be performed by a certified electrician.
Air Requirements
The customer must furnish compressed air at 145 ± 30psi. The customer must furnish an air supply line with a 1/4
inch NPT female fitting to connect to the tire changer.
