6. Operating (Usage)
The APS iArmor Drop Step Running Boards are designed to provide an accessible intermediate step for easier entry and exit from your Toyota 4Runner. The unique patented drop step design offers a lower stepping surface compared to traditional running boards.
- When entering or exiting the vehicle, place your foot firmly on the textured step surface.
- Ensure your footing is secure before applying full weight.
- Avoid using the running boards as a jacking point or for purposes other than vehicle entry/exit.
7. Maintenance
To ensure the longevity and appearance of your APS iArmor Drop Step Running Boards, follow these maintenance guidelines:
- Cleaning: Clean the running boards regularly with mild soap and water. Avoid abrasive cleaners, harsh chemicals, or stiff brushes that could damage the triple-layer powder coating finish. Rinse thoroughly and dry with a soft cloth to prevent water spots.
- Inspection: Periodically (e.g., every 3-6 months or after off-road use) inspect all mounting hardware, including bolts, nuts, and brackets. Ensure they are tight and free from corrosion or damage. Re-tighten any loose hardware to prevent rattling or instability.
- Damage Check: Check for any signs of physical damage, such as dents, bends, or cracks, which could compromise the structural integrity of the running boards.
8. Troubleshooting
If you encounter any issues with your APS iArmor Drop Step Running Boards, consider the following:
- Rattling or Looseness: This is typically caused by loose mounting hardware. Re-inspect all bolts and nuts, and tighten them securely according to the installation instructions.
- Unusual Noises: If you hear squeaking or grinding, it may indicate friction between components or loose parts. Check for proper alignment and tightness of all connections.
- Difficulty Stepping: Ensure the step surface is clear of debris, mud, or ice. The textured surface is designed for grip, but extreme conditions may reduce traction.
If problems persist after troubleshooting, contact APS customer support for further assistance.
