Operation

4.1 Operating Notes

• Check that the air pipe connection is in place, ensure no air leakage, and confirm the operation space meets requirements before starting work.
• Before any operation, release the gas in the tire and remove the balance block of the tire balancing device.

4.2 Disassemble Operation Process

4.2.1 Bead Loosening

• Deflate the tire completely by removing the valve core from the valve stem. To avoid damaging the clamps and/or wheel, move the clamps to their full inward position before positioning a tire for bead loosening.
• Pull the bead breaker blade away from the machine and roll the wheel into position.
• Ensure the valve stem is at the 12 o'clock or 6 o'clock position.
• Position the bead breaker blade against the tire, next to, but not on, the rim or sidewall. Press the breaker pedal to actuate the blade and loosen the bead. It may be necessary to loosen the bead in multiple locations. Use extra care on larger wheels/tires and alloy wheels.
• Turn the wheel around and repeat the procedure on the other side. This should be the long side of the drop center. It will be easier to clamp the wheel to the table top if the lower bead is loosened last.
• Determine the mounting side of the wheel; it is the narrow side of the drop center.

4.2.2 Wheel Clamping

• Fix the block in the left helper arm.
• Place the tire/wheel assembly on the Table Top with the mounting side up.
• Use the Wheel Clamp Foot Pedal to move the clamps inward (pedal down) or outward (pedal up).

4.2.3 Tire Mounting

• Apply tire manufacturer's approved rubber lubricant liberally to the entire circumference of both upper and lower beads after loosening the bead and placing the wheel on the table.
• After the wheel is secured to the Turntable, swing the Vertical Arm into position. Use the large adjusting knob to position the Mount/Demount Head directly over the edge of the rim.
• Push the Vertical Shaft down and position the Mount/Demount Head into contact with the rim edge.
• Pull the locking handle towards you to lock the Vertical Shaft into position. As the slide is locked, the Mount/Demount Head will move upward approximately 1/8 inch and backward 1/8 inch from the rim edge. The Mount/Demount head roller should not be in contact with the rim edge.

NOTE: This clearance will be maintained as long as the vertical shaft remains locked. The operator may swing the arm out of the way and back into place again without needing to reposition the head when changing a like set of wheels. The tool clearance may change with machine use and should be inspected often. Failure to do so...

• Rotate the wheel using the Turntable Pedal until the valve stem is at the 3 o'clock position relative to the Mount/Demount Head.
• Insert the smooth curved end of the Bead Lifting Tool over the tab side of the Mount/Demount Head and below the top bead of the tire.
• Push the Bead Lifting Tool down and away from the wheel to lower the bead into the Drop Center while lifting up on the Table Top Pedal to rotate the turntable counter-clockwise.

NOTE: For low profile tires, get the upper bead into the drop.

• Push the Bead Lifting Tool down toward the wheel to lift the tire bead up and over the tab of the demount head. Hold the Bead Lifting Tool in this position. Depress the Table Top Foot Pedal to rotate the wheel clockwise.
• Hold the Bead Lifting Tool down until the upper bead is solidly above the rim. Continue rotating the wheel clockwise until the upper bead is completely demounted.
• Liberally lubricate the lower bead again if there was any difficulty lubricating it earlier.
• Insert the smooth curved end of the Bead Lifting Tool over the tab end of the Mount/Demount Head and below the lower bead of the tire. Push the Bead Lifting Tool down toward the wheel to lift the tire bead up and over the left tab side knob portion of the Mount/Demount Head. Hold the Bead Lifting Tool in this position.

Depress the Table Top Pedal to rotate the wheel. The Mount/Demount Head will guide the bead up and over the edge of the wheel. Continue rotation until the lower bead is demounted.

CUSTOM AND SPECIAL WHEELS

IF A CUSTOM WHEEL IS DAMAGED WHILE DEMOUNTING, STOP, AND AVOID DAMAGING THE OTHER WHEELS. CONTINUE ONLY WHEN THE CAUSE IS IDENTIFIED AND CORRECTED.

ALLOY WHEELS

Some manufacturers offer wheels with little or no drop center. These are not DOT approved. The tire or wheel, or both, can be damaged, and the tire could explode under pressure, resulting in serious injury or death. If you attempt to mount/demount this type of wheel, use extreme caution.
