Setup and Installation

Proper installation of the centering cone is crucial for accurate and safe tire changing operations.

1. Prepare the Machine: Ensure your tire changer machine is clean and free of debris, especially the center post where the cone will be mounted.
2. Select the Correct Cone: Verify that the hold down centering cone is compatible with your specific tire changer model and the wheel you are working on. This cone is designed for Coats models 1010, 2020, 3030, 4040, 4040SA, 4050, and FMC models 7600, 7700. It also fits Hofmann/Monty 2700.
3. Mount the Cone: Slide the centering cone onto the machine's center post. Ensure it sits flush and securely.
4. Position the Wheel: Place the wheel onto the center post, ensuring it rests firmly against the cone. The cone's tapered design should center the wheel automatically.
5. Secure the Wheel: Use the machine's hold-down mechanism (e.g., wing nut, quick-release nut) to firmly secure the wheel against the centering cone. Do not overtighten, but ensure there is no play.

Operating Instructions

Once the centering cone and wheel are securely installed, proceed with tire changing operations according to your tire changer machine's specific instructions.

• Ensure the wheel is perfectly centered and stable before initiating any tire mounting or demounting procedures.
• The cone's design helps prevent wheel damage during the process by providing a stable and non-abrasive contact surface.
• Regularly check the tightness of the hold-down mechanism during operation, especially for stubborn tires.

Maintenance

To ensure the longevity and optimal performance of your centering cone, follow these maintenance guidelines:

• Cleaning: After each use, wipe down the cone with a clean cloth to remove any tire residue, grease, or dirt.
• Inspection: Periodically inspect the cone for signs of wear, cracks, or deformation. Pay close attention to the tapered surfaces and the central bore.
• Storage: Store the cone in a clean, dry place when not in use to prevent corrosion or damage.
• Lubrication: While the cone itself does not require lubrication, ensure the machine's center post and hold-down threads are properly lubricated as per your machine's manual.

Troubleshooting

If you encounter issues while using the centering cone, consider the following:

• Wheel Not Centering:
  • Ensure the cone is fully seated on the machine's center post.
  • Verify the wheel's hub opening is compatible with the cone's taper.
  • Check for debris between the cone and the wheel or the cone and the machine.
• Cone Appears Loose:
  • Confirm the hold-down mechanism is properly tightened.
  • Inspect the cone and center post for excessive wear that might prevent a snug fit.
• Damage to Wheel:
  • Ensure the cone is clean and free of sharp edges or burrs.
  • Always use protective gaskets or pads if recommended by your tire changer manufacturer, especially for delicate wheel finishes.
