4. Setup and Installation

1. Preparation: Ensure the mounting surface on your recreational vehicle is clean, flat, and structurally sound. It must be capable of safely supporting the step's weight and dynamic loads during use.
2. Bracket Selection: Select the appropriate installation brackets (9mm, 35mm, 62mm, or 88mm) that best match your vehicle's mounting points and desired step height.
3. Positioning: Carefully position the step unit and chosen brackets in the intended installation location. Mark the precise drilling points for the mounting hardware.
4. Drilling: Drill pilot holes according to the manufacturer's recommendations for the specific mounting hardware. Exercise caution to avoid damaging any internal wiring, plumbing, or structural components of the vehicle.
5. Secure Mounting: Attach the step unit to the vehicle using the selected brackets and appropriate mounting hardware. Ensure all bolts and fasteners are tightened securely to prevent movement. Verify that the step is level and stable.
6. Functionality Test: After installation, extend and retract the step multiple times to confirm smooth operation and secure locking in both the fully open and fully closed positions.

5. Operating Instructions

• Extending the Step: Gently pull the step outwards from its stowed position. Continue pulling until it fully extends and audibly clicks into its locked position. Verify it is stable before use.
• Retracting the Step: Push the step inwards towards the vehicle. Apply steady pressure until it is fully retracted and securely locks into its closed position. Always ensure the step is fully stowed before driving.
• Using the Step: Step onto the corrugated surface. The rounded corners are designed to glow in the dark, providing enhanced visibility for safe use during nighttime or in dimly lit areas.

6. Maintenance

• Cleaning: Clean the step regularly using mild soap and water. Avoid using abrasive cleaners, harsh chemicals, or stiff brushes that could damage the anodized aluminum finish.
• Lubrication: Periodically apply a suitable, weather-resistant lubricant to all moving parts and hinges to ensure smooth operation and prevent corrosion.
• Inspection: Conduct routine inspections of all mounting hardware, brackets, and the step's sliding mechanism. Check for any signs of wear, corrosion, cracks, or loose fasteners. Tighten any loose bolts immediately.
• Winter Storage: If the vehicle is to be stored for extended periods, especially in cold or harsh climates, ensure the step is thoroughly cleaned and dried before retraction. Consider applying a protective coating if the step will be exposed to extreme weather conditions.

7. Troubleshooting

• Step does not extend or retract smoothly: Check for any visible obstructions in the sliding mechanism. Clean any debris from the tracks. Apply lubricant to the moving parts. Inspect for bent or damaged components that may be impeding movement.
• Step does not lock securely: Ensure the step is pushed or pulled completely into its fully extended or retracted position. Inspect the locking mechanism for any damage, wear, or foreign objects preventing proper engagement. Verify correct installation.
• Step feels unstable or wobbly: Re-check all mounting hardware to ensure it is securely tightened. Confirm that the correct installation brackets were used and installed properly. Inspect the vehicle's mounting surface for any structural issues or damage.
