WARNING

Operator Protective Equipment

Personal protective equipment helps make tire changing safer. However, equipment does not take the place of safe operating practices. Always wear durable work clothing during tire service activity. Shop aprons or shop coats may also be worn, however loose fitting clothing should be avoided. Tight fitting leather gloves are recommended to protect operator’s hands when handling worn tires and wheels. Sturdy leather work shoes with steel toes and oil resistant soles should be used by tire service personnel to help prevent injury in typical shop activities. Eye protection is essential during tire service activity. Safety glasses with side shields, goggles, or face shields are acceptable. Back belts provide support during lifting activities and are also helpful in providing operator protection. Consdieration should also be given to the use of hearing protection if tire service activity is performed in an enclosed area, or if noise levels are high.

OPERATING INSTRUCTIONS

The unit must be properly operated and properly maintained to help avoid accidents that could damage the unit and injure the operator or bystanders. This section of the Operating Instructions manual review basic operations and use of controls. These instructions should be reviewed with all employees before they are allowed to work with the machine. Keep these instructions near the machine for easy reference.

BEAD LOOSENING AND DEMOUNTING

This machine may operate differently from machines

you have previously operated. Practice with a regular steel wheel and tire combination to familiarize yourself with the machine’s operation and function.

A. Remember to remove all weights from both sides of the wheel. Weights left on back side of wheel may cause the wheel to be clamped unlevel. This may result in the combination mount/demount head contacting the rim causing scratches. On alloy wheels, always rotate the wheel one turn after setting the head to insure proper wheel chucking.

B. Always review nicks and scratches with owners of expensive wheel and tire combinations prior to servicing.

C. Review the performance wheel section of this manual prior to servicing performance tire/wheel combinations.

1. Deflate tire completely by removing the valve

core from the valve stem (Figure 1).

Figure 1 – Remove Valve Core to Deflate Tire

NOTE: Loosening the beads on a partially or fully inflated tire is unsafe and causes excess movement and friction against the bumper pads and excessive wear on pivots. Deflate the tire completely to prolong the life of your machine.

D. Always loosen the bead on the narrow side of the wheel’s drop center first. See Figure 4 for more information on the drop center.

E. The clamps on the table top may extend beyond the table top itself. To avoid damaging the clamps, move them to their full inward position before positioning a tire for bead loosening.

F. Use extra care in positioning the bead loosener shoe on larger wheels/tires, and on alloy wheels. Make sure the shoe rests next to but not on the rim, and not on the tire sidewall.

2. Pull the bead loosener shoe away from the machine and roll wheel into position. The valve stem should be in the 2 o’clock position. Position the bead loosener shoe against the tire next to, but not on, the rim. Press the loosener pedal to actuate the shoe and loosen the bead. It may be necessary to loosen the bead in multiple locations around the tire (Figure 2).

Figure 2 – Position Tire and Bead Loosener Shoe

3. Turn wheel around and repeat loosening procedure on the other side of the wheel. This should be the long side of the drop center (see Figure 3).

G. It will be easier to clamp the wheel to the table top if the lower bead is loosened last.

4. Determine the mounting side of the wheel. The mounting side is the narrow side of the drop center (Tire removed in Figure 3 for clarity).

Figure 3 – Determine Mounting Side of Wheel

5. Place tire/wheel assembly on table top with mounting side up (Figure 4). Use the clamp control pedal to move the clamps inwards (push pedal down) or outwards (toggle pedal up).

Figure 4 – Place Tire/Wheel Assembly on Table Top

Clamp steel wheels from the inside (clamps push

outwards against wheel). Clamp mag and custom wheels from outside (Clamps push inwards against the outside rim edge). Refer to the Performance Tires and Wheels section.

Figure 5 - Apply Rubber lubricant to the beads

6. Apply tire manufacturer’s approved rubber lubricant liberally to entire circumference of both beads after loosening and placing on table top. Using L.H. & R.H. helpers to hold down top bead while rotating wheel and lower lift disk for bottom bead will make lubrication easier (Figure

5).

Figure 6 - Position Mount/Demount Tool

Move the tower forward into position. Pull the locking valve button forward to release the slides. The vertical slide will descend. Pull the slide handle to move the demount head into contact with the rim edge. Push the locking valve button to lock the slides into place. As the slides are locked, the mount/demount head will move upward approximately 1/8 inch and backward 1/8 inch from the rim edge. (Figures 6 & 7)

Figure 7 - Adjust Slides to Position Head Roller

8. The mount/demount head roller should not be in contact with the rim edge & the flat area under the head should be raised above rim flange (figure 7).

Figure 8 - Proper Mount/Demount Head Postion

9. Check head positioning. Mount/demount head

should be positioned with 1/8 to 3/16" clearance between the top of the rim edge and the bottom of the head, and 1/8 to 1/4 inch clearance between the rim edge and the head roller. This clearance will be maintained as long as the slide locking valve remains locked. The operator may move the tower back out of the way and back into place again without needing to reposition the head (when changing a like set of wheels) (Figure 8).

H. The tool clearance may change with machine use and should be inspected often. Failure to maintain the proper clearance may result in damage to the wheel rim and/or tire.
