2. Safety Information
WARNING: Please read and follow all instructions carefully for safe installation and use. Failure to do so may result in injury or damage to the product.
- Always wear appropriate personal protective equipment, including heavy-duty gloves, safety glasses, and long sleeves, during assembly to prevent cuts from sharp metal edges.
- Assembly requires at least two adults. Do not attempt to assemble the shed alone.
- Ensure the assembly area is clear of obstructions and hazards.
- Do not assemble the shed in high winds or adverse weather conditions.
- Secure the shed to a solid, level foundation (concrete or wood) to prevent tipping or movement. Anchor bolts are not included and must be purchased separately.
- Keep children and pets away from the assembly area.
- Periodically check all fasteners for tightness and re-tighten as necessary.

4. Site Preparation
Proper site preparation is crucial for the stability and longevity of your shed. Choose a location that is:
- Level: The shed must be installed on a completely flat and level surface. An uneven surface can lead to misalignment of panels, difficulty with door operation, and structural instability.
- Solid: A concrete slab or a sturdy wooden foundation is recommended. The shed does not include a floor, so a prepared base is essential.
- Well-Drained: Ensure the site has good drainage to prevent water accumulation around the shed, which can lead to corrosion over time.
- Accessible: Allow sufficient space around the shed for assembly and future maintenance.

- Door Tracks: Keep the door tracks clean and free of debris to ensure smooth operation of the sliding doors. Lubricate with a silicone-based spray if necessary.
- Ventilation: Ensure the ventilation grilles are clear of obstructions (e.g., leaves, dirt) to allow for proper airflow.
- Rust Prevention: Although made from hot-dipped galvanized steel, promptly address any scratches or damage to the paint finish with touch-up paint to prevent localized corrosion.
8. Troubleshooting
- Difficulty with Door Operation: Check if the shed is level. Ensure door tracks are clean and free of debris. Inspect for any bent panels or misaligned rollers.
- Water Leaks: Verify that all roof panels are correctly overlapped and all sealing strips are properly installed. Check for any gaps around the base or corners. Ensure the shed is anchored to a level foundation.
- Misaligned Panels: This often indicates an uneven foundation or incorrect assembly steps. Disassemble the affected section and re-assemble carefully, ensuring the base is perfectly level.
