- Prepare the Base: Place the base panel on a clean, flat, and stable surface.

- Install Front Panel: Attach the front panel to the assembled side and base panels. This step may require gentle tapping with a rubber mallet to ensure a snug fit.

- Attach Hinges: Mount the hinges to the back panel and the lid using the designated screws. Ensure they are aligned properly for smooth lid operation.
- Install Gas Struts: Attach the gas struts to their respective mounting points on the lid and the side panels. Ensure the struts are installed with the correct orientation as shown in the diagram. These struts assist in opening and holding the lid.

Operating Instructions
- Opening the Lid: Gently lift the lid. The integrated gas springs will assist in raising the lid and holding it open, preventing it from slamming shut.

- Locking Mechanism: The box is designed to be lockable. A padlock (not included) can be inserted through the designated eyelet on the front of the lid to secure your belongings.

Maintenance
- Cleaning: Clean the box regularly with a soft cloth, mild soap, and water. Avoid abrasive cleaners or harsh chemicals, as these can damage the plastic. Rinse thoroughly with clean water.
- Weather Protection: While the box is weather and UV resistant, regular cleaning helps maintain its appearance and protective qualities. Ensure the lid is fully closed during rain or snow to keep contents dry.
- Inspection: Periodically check all screws and connections to ensure they remain tight. Retighten if necessary. Inspect the gas struts for any signs of wear or damage.
- Winter Storage: If storing the box empty during winter, ensure it is clean and dry. While designed for outdoor use, extreme conditions may warrant additional protection.
