6. Maintenance

To ensure the longevity and optimal performance of your YHTAUTO Running Boards, regular maintenance is recommended:

• Regular Cleaning: Clean the running boards periodically with mild soap and water to remove dirt, mud, and road grime. Avoid abrasive cleaners or harsh chemicals that could damage the finish.
• Inspect Fasteners: Periodically check all mounting bolts and nuts to ensure they remain tight. Re-tighten any loose fasteners to prevent rattling or instability.
• Check for Damage: Inspect the running boards for any signs of damage, such as dents, scratches, or corrosion. Address any issues promptly to prevent further deterioration.
• Rubber Pad Condition: Ensure the injection-molded polymer step pads are free from excessive wear or damage to maintain optimal grip.

7. Troubleshooting

If you encounter any issues with your running boards, consider the following:

• Loose or Rattling Boards: This is typically caused by loose mounting hardware. Re-check and tighten all bolts and nuts as described in the installation guide.
• Difficulty Stepping: Ensure the step pads are clean and free of debris. If the boards feel unstable, re-verify the tightness of all mounting points.
• Unusual Noises: Investigate any squeaking or creaking sounds. These may indicate loose connections or contact between components. Lubricate moving parts if necessary, or tighten fasteners.
• Corrosion or Finish Issues: While designed for resistance, prolonged exposure to harsh conditions without cleaning can affect the finish. Clean regularly and consider protective waxes or coatings.

If problems persist, consult a qualified technician or contact YHTAUTO customer support.
