PRODUCT DESCRIPTION
Prior to using the Tire Changer, it is recommended that you study and familiarize
yourself with the main components of the unit. (See Figure E.)

Page 7SKU 45656 For technical questions, please call 1-800-444-3353.
ASSEMBLY INSTRUCTIONS
NOTE: All parts below refer to the parts listed on pages 17 through 22 of this
manual.
1. Temporarily remove the four mounting Bolts, Washers, and Nuts located at the
top/rear of the Body Assembly. (See Figure F.)
2. Set the column (C) on the body assembly (B) insuring the threaded studs line up
with the mounting holes on the bottom of the column mounting ange. Secure
the column to the body with the nuts and washers (A) provided.
3. Pneumatic Hook Up: Connect the ination gun to its connector. Connect the tire
changer to a compressed air network using the connector which is on the air-
water separator (D) located right side of the base assembly.
4. Electric at connection: Before making any electric link up, check to be certain
that the main voltage corresponds to what is stamped on the voltage tag. It is
absolutely essential that the system is equipped with a good grounding circuit.
5. WARNING: The Tire Changer requires the assembly of a UL, CSA, or CE listed,
220 Volt, 3-Prong Electrical Plug (not provided) onto the unit’s electrical power cord.
The National Electric Code requires that the GREEN wire on the unit must be used
as the GROUND wire. The “HOT” wires on the power cord are the BLACK and
WHITE wires. Do not attempt to alter the 220 Volt, 3-Prong Plug or its assembly to
the power cord (as mentioned above) in any way. In addition, it is recommended
that this assembly procedure be carried out by a qualied technician.

OPERATING INSTRUCTIONS
NOTE: All parts below refer to the parts listed on pages 17 through 22 of this
manual.
To Perform Preliminary Operating Tests:
Connect the Tire Changer to its air and electrical supply sources, and allow1.
adequate time for the compressed air system to reach the recommended 110
PSI. (See Figures A, C, D, and E.)
When the Reverse Pedal (59E) is fully depressed, the Turntable (1C) should turn2.
in a clockwise direction. (See Figures B and E.)
When the Reverse Pedal (59E) is raised, the Turntable (1C) should turn in a3.
counterclockwise direction.
Press the Bead Breaker Pedal (26E) to activate the Paddle (7B). When the4.
Pedal is released, the Paddle should return to its original position.
Press the Jaw Clamp Pedal (26E) once to open the four Jaws (17C). Press the5.
Pedal again to close the Jaws.

4. Depress the Bead Breaker Pedal (26E) fully to activate the Paddle (7B). Release
pressure on the Bead Breaker Pedal when the Blade has reached the end of its
travel and/or when the tire bead is broken.
(See Figures B, E, and H.)
5. Rotate the tire slightly, and repeat the procedure around the entire circumference
of the wheel rim until the bead is completely detached from the rim.
6. Repeat the above Steps for the other side of the wheel/tire.
To Remove The Tire From The Wheel:
1. WARNING: Before carrying out this procedure, deate the tire fully, and remove
all the wheel weights.
2. Spread tire grease (or a similar lubricant) liberally on the complete circumference
of the broken tire bead. NOTE: Failure to lubricate the tire bead may cause
serious damage to the bead.
3. Place the wheel/tire evenly on the Turntable (1C). (See Figure E.)
4. To lock the wheel on the Turntable (1C), proceed as follows according to the
wheel rim size:
Rims from 10” to 18”: Position the four Jaws (17C) according to the reference
mark located on the Turntable (1C) by depressing the Jaw Clamp Pedal (26E)
halfway down. (See Figures B and E.)

Page 10SKU 45656 For technical questions, please call 1-800-444-3353.
Place the wheel on the four Jaws (17C) and, while keeping the wheel rim
pressed down, depress the Jaw Clamp Pedal (26E) as far down as it will go.
Check to make sure the wheel is rmly secured by the Jaws (17C).
Rims from 12” to 20”: Position the four Jaws (17C) so that they are completely
closed.
Place the wheel on the four Jaws (17C) and depress the Jaw Clamp Pedal (26E)
to open the Jaws, thereby locking the wheel rim in place.
Check to make sure the wheel is rmly secured by the Jaws (17C).

Head (15A). (See Figures E and I.)
7. Move the tire bead over the Mounting Head (15A) by pulling upward on the
Reverse Pedal (59E). NOTE: To avoid damaging the inner tube (if there is one),
it is recommended to perform this Step with the inner tube valve stem positioned
about 1” to the right of the Mounting Head. (See Figures B and I.)
8. With the Lever (1F) held in position, rotate the Turntable (1C) in a clockwise
direction by fully depressing the Reverse Pedal (59E). Continue until the tire is
