1. Getting Started
1.1 Introduction
1.1.a – PURPOSE OF THE MANUAL
The purpose of this manual is to provide the instructions necessary for optimum operation,
use and maintenance of your machine. If you sell this machine, please deliver this manual
to the new owner. In addition, so we can contact our customers with any necessary safety
information, please ask the new owner to complete and return to Hunter the change of
ownership form attached to the last page of this manual. Alternately, the new owner can send
an email to [e-mail].
This manual presumes that the technician has a thorough understanding of rim and tire
identication and service. He/she must also have a thorough knowledge of the operation and
safety features of all associated tools (such as the rack, lift, or oor jack) being utilized, and
have the proper hand and power tools necessary to work in a safe manner.
The rst section provides the basic information to safely operate the TCX50 tire changer
family. The following sections contain detailed information about equipment, procedures,
and maintenance. “Italics” are used to refer to specic parts of this manual that provide
additional information or explanation. For example, Refer to “Equipment Components” page
21. These references should be read for additional information to the instructions being
presented.
The owner of the tire changer is solely responsible for enforcing safety procedures and
arranging technical training. The tire changer is to be operated only by a qualied and trained
technician. Maintaining records of personnel trained is solely the responsibility of the owner or
management.
The TCX50 tire changer family is intended for mounting, demounting, and inating most tires
with an approximate dimension of 50 inches in diameter and 15 inches in width.
Copies of this manual and of the documents accompanying the machine may be obtained

2. Overinated tires can explode, producing hazardous ying debris that may result in an
accident.
3. Tires and Rims that are not the same diameter are “mismatched.” Never attempt to mount
or inate any tire and rim that are mismatched. For example, never mount a 16.5” tire on
a 16” rim and vice versa. This is very dangerous. A mismatched tire and rim could explode
and result in an accident.
4. Never exceed the bead setting pressure (gauge on hose) provided by the tire
manufacturer, as stated on the sidewall of the tire.
5. Never place your head or any part of your body over a tire during the ination process or
when attempting to seat beads. This machine is not intended to be a restraining device for
exploding tires, tubes or rims.
6. Never use an ination source other than the regulated pressure system on the tire changer.
7. Use a safety cage in accordance with tire manufactures recommendations if ination
pressures beyond the tire changer equipped regulated air is required.
An exploding tire and rim may be propelled upward and outward with enough force
to cause serious injury or death.
Never mount any tire unless the tire size (molded into the sidewall) matches the rim
size (stamped into the rim) exactly or if the rim or tire are defective or damaged.
Never exceed tire pressure recommended by tire manufacturer.
This tire changer is not a safety device and will not restrain exploding tires and rims.
keep area clear of bystanders.
