4. Maintenance
To ensure the longevity and optimal performance of your joystick knob and gaiter, follow these simple maintenance guidelines:
- Cleaning: Wipe the silicone components with a damp cloth and mild soap as needed. Avoid harsh chemicals or abrasive cleaners, which can damage the material.

5. Troubleshooting
If you encounter issues during or after installation, consider the following:
- Knob or Gaiter Does Not Fit: Verify that the dimensions of your joystick controller match the universal size specifications provided in this manual. While designed for wide compatibility, some specific models may vary.
- Loose Fit: Ensure both the gaiter and knob are fully seated and pushed down firmly during installation. A loose fit can affect control and comfort.
