situations.

4. Use safety equipment. Always wear eye protection. Always wear

ANSI-approved safety impact goggles and a full face shield when using

and/or installing this product.

TOOL USE AND CARE

1. Do not force the tool. Use the correct tool for your application. The correct

tool will do the job better and safer at the rate for which it is designed.

2. Store idle tools out of reach of children and other untrained persons. Tools

are dangerous in the hands of untrained users.

3. Maintain tools with care. Properly maintained tools are less likely to malfunc-

tion and are easier to control. Do not use a damaged tool. Tag damaged tools

“Do Not Use” until repaired.

3. Keep bystanders, children, and visitors away while operating tools and

equipment. Distractions can cause you to lose control. Provide barriers or

shields as needed.

ASSEMBLY INSTRUCTIONS

1. Locate the Hex Bolts (6), Lock Washers (11), Hex Head Nuts (12), Center Post

(1), and the Pedestal Base (13). (See Assy. Diagram.)

2. Bolt the Pedestal Base (13) to the Center Post (1), using the Hex Bolts (6), Lock

Washers (11), and Hex Head Nuts (12). NOTE: The end of the Pedestal Base

with the triangular stop should be directly in front of the Bead Breaker Handle (7)

and Bead Breaker Shoe (10). (See Assy. Diagram.)

3. Bolt the two Side Base Channels (9) into place. (See Assy. Diagram.)

4. Temporarily set the Tire Changer aside. Then drill four holes in the concrete floor

surface equal to the

length

of four 7/16” diameter cement anchors (not included)

you will use to secure the Tire Changer to the floor surface. (See Figure A.)

5. Once the four 7/16” diameter holes are drilled, blow out the concrete dust from

each of the holes. (See Figure A.)

6. Set the Tire Changer back on the concrete floor surface, and align its four

mounting holes at its base with the four pre-drilled holes in the floor surface.

7. If necessary, level the Tire Changer on the concrete floor surface using a

carpenter’s level and steel shims (neither included).

8. Use a hammer (not included) to tap the four cement anchors through the four

mounting holes in the base of the Tire Changer and into the concrete floor sur-

face. Continue tapping the cement anchors until their washer rests against the

base of the Tire Changer. (See Figure A.)

9. Firmly tighten the nuts of the four cement anchors to secure the Tire Changer to

the concrete floor surface. (See Figure A.)

1. Choose a concrete floor surface location for the Tire Changer that is well lighted,

offers adequate workspace, and is away from high pedestrian traffic areas.

2. The concrete floor surface should be at least 4” in depth. (See Figure A.)

3. With assistance, move the Tire Changer to the location. Use the Tire Changer’s

four 7/16” mounting holes at its base as a template for which four 7/16” holes will

be drilled in the concrete surface. Do not use a concrete drill bit larger in

diameter than 7/16”. (See Figure A.)

OPERATING INSTRUCTIONS

Bead Breaking:

1. Before starting, use a rubber lubricant (not included) to help make bead break-

ing, mounting, and demounting easier.

2. Deflate the tire completely.

3. To break the bead from the rim of the tire, lay the tire flat on the Pedestal Base

(13). The triangular stop is used to keep the tire from sliding.

4. Insert the flat end of the Mount/Demount Bar (14) into the Bead Breaker Handle

(7).

5. Set the Bead Breaker Shoe (10) on the tire against the edge of the rim. As you

work, you may need to adjust the Bead Breaker Shoe height by removing the

Clevis Pegs (5) and moving the Shoe to the appropriate height. Then, reinsert

the Clevis Pegs.

6. Push down on the Mount/Demount Bar (14) to force the bead off the rim. If the

bead does not come off all at once, turn the tire and try again in several loca-

tions.

7. Turn the tire over, and repeat Steps #1 through #6 above.

Demounting And MountingTires:

1. After the bead is broken, place the tire up on the machine with the valve stem

facing up and the Wheel Lug Peg (3) sticking up through the lug hole of the rim.

2. Place the Spider Pedestal (4) over the Center Post (1) with the tapered side

going into the wheel hub.

3. Screw the Pedestal Cap (2) onto the Center Post (1). Lock the Spider Pedestal

(4) into place by tightening snugly by hand. Hand tightening should be adequate.

However, if you want more pressure place the flat end of the Mount/Demount

Bar (14) through the top of the Pedestal Cap and use extra leverage to tighten

the Pedestal Cap further.

4. Once the tire is held securely in place, force the flat end of the Mount/Demount

Bar (14) in between the tire and the rim. This should be done with the flat end of

the Mount/Demount Bar against the rim. Pull the Mount/Demount Bar toward

you and across the tire to force the edge of the bead over the rim.

SKU 34542 For technical questions, please call 1-800-444-3353 PAGE 8

5. Work the Mount/Demount Bar (14) all the way around the Center Post (1) to

demount the bead completely.

6. Pull the tire up toward the top of the bead. Place the flat end of the

Mount/Demount Bar (14) between the tire and the rim as before. Then, repeat

the process to remove the tire from the rim completely.

7. Repair the tire. Then, mount the tire back on the rim and set the tire on top of

the rim.

8. Hook the end of the Mount/Demount Bar (14) over the edge of the rim.

9. Push the tire forward over the edge of the rim at the place the Mount/Demount

Bar (14) is.

10. Position the bead so it will slide across the flat portion of the hook end of the

Mount/Demount Bar (14).

11. Press down on the tire with one hand against the rim. With the other hand, pull

the Mount/Demount Bar (14) clockwise around the Center Post (1) until the bead

starts to mount on the rim. It should only have to move a few inches before you

can let go of the tire and use both hands on the Mount/Demount Bar.

12. Continue around the rim until the tire mounts over the edge of the bead. Repeat

this procedure on the second bead to completely mount the tire.

13. IMPORTANT: If the tire bead starts to seat while you are mounting the tire, the

tire will need to stretch more and will be more difficult to mount. To prevent this,

push down on the tire so it doesn’t seat on the upper edge of the rim during

mounting.

14. NOTE: The bead running across the top of the Mount/Demount Bar (14) keeps

the Bar hooked on the edge of the rim. The tire bead will run across the top (flat

part of the mounting end of the Bar) and against the curved Wheel Lug Peg (3)

when mounting the tire on the rim.

ATV Tires:

1. NOTE: ATV tires are difficult to demount and mount because of their small

diameter. Additionally, the tires are soft and bend easily when breaking the bead.

2. If the Bead Breaker Shoe (10) slides off the tire, hold the Shoe in place and work

around the rim breaking the bead a little at a time.

3. Place lubricant between the tire and rim to make it slide off easier.

SKU 34542 For technical questions, please call 1-800-444-3353 PAGE 9

4. If the wheel has a tall rim with a small inside diameter so that the rim does not go

over the round plate on the Center Post (1) and will not accept the Spider Pedes-

tal (4), or let the Wheel Lug Peg (3) through its hole, you should still be able to

use this Tire Changer to demount and mount the tire. Most rims are held in

place adequately by tightening the Center Post Cap down snugly. With the Cap

in place, you should still be able to hold the rim in place to mount and demount

the tire as discussed previously.

INSPECTION, MAINTENANCE, AND CLEANING

1. Before each use, inspect the general condition of the Tire Changer. Check for

loose screws, misalignment or binding of moving parts, cracked or broken parts,

and any other condition that may affect the safe operation of the Tire Changer. If

abnormal noise or vibration occurs, have the problem corrected before further

use. Do not use damaged equipment.

2. To clean the Tire Changer, use a mild detergent or mild solvent. Then, dry.

3. CAUTION! All maintenance, service, or repairs not mentioned in this

manual must only be performed by a qualified service technician.
