Maintenance
To ensure the longevity and appearance of your Snailfly Running Boards, follow these maintenance guidelines:
- Regularly clean the running boards with mild soap and water to remove dirt, salt, and debris.
- Inspect all mounting hardware periodically (e.g., every 3-6 months) to ensure bolts remain tight and secure. Re-tighten if necessary.
- Check the anti-slip rubber surface for any signs of wear or damage.
- Avoid using abrasive cleaners or harsh chemicals that could damage the finish.
- For optimal protection, consider applying a protective wax or sealant to the aluminum surfaces.
Troubleshooting
Issue: Running Board Feels Loose or Unstable
Possible Cause: Loose mounting bolts or improperly installed brackets.
Solution:
- Carefully inspect all mounting points and hardware under the vehicle.
- Ensure all bolts are securely tightened. Refer to the detailed PDF manual for torque specifications.
- Verify that all required brackets are installed. In some cases, specific rear mounting brackets or holes might be overlooked during manufacturing or installation, leading to instability. If a bracket appears missing or holes are not present where expected, contact Snailfly customer support for assistance.
- If the issue persists after re-tightening, professional inspection and re-installation are recommended.
