Setup and Assembly
Assembly of your Devoko Deck Box is designed to be straightforward. Follow the step-by-step instructions below. It is recommended to assemble the unit on a soft surface like grass to prevent scratching.
- Unpack Components: Carefully remove all parts from the packaging. Verify that all components are present according to the parts list (not provided in this manual, refer to your product packaging).
- Assemble Base: Connect the base panel (typically labeled 'B') to the side panels (typically labeled 'C'). Ensure the pieces click securely into place.
- Attach Front Panel: Secure the front panel (typically labeled 'A') to the assembled base and side panels. Listen for clicking sounds to confirm proper engagement.
- Attach Back Panel: Connect the back panel (typically labeled 'D') to complete the main body of the box.
- Install Hydraulic Hinges: Attach the hydraulic air rods to the designated points on the lid and the main body of the box. Use a Phillips head screwdriver or a drill (with caution to avoid stripping screws) to secure the screws. Ensure two screws are used at the bottom and two at the top for each hinge.
- Attach Lid: Carefully align the lid with the main body and attach it to the hydraulic hinges. Test the opening and closing mechanism to ensure smooth operation.

Operating Instructions
Opening and Closing the Lid
The deck box features hydraulic air rods for smooth and safe operation. To open, gently lift the lid. The hydraulic rods will assist in raising and holding the lid open. To close, gently push the lid down until it fully engages with the base. The hydraulic rods will ensure a slow and controlled descent, preventing sudden slams.
Lockable Feature
For added security, the deck box is designed with a lockable mechanism. A padlock (not included) can be inserted through the designated hole on the front of the lid to secure your stored items.
Using as a Bench
The Devoko 100 Gallon Deck Box comes with a waterproof seat cushion, allowing it to double as a comfortable bench. It is designed to support a maximum weight of 500 pounds. Ensure the lid is fully closed and latched before using it as seating.

Maintenance
To ensure the longevity and appearance of your Devoko Deck Box, follow these simple maintenance guidelines:
- Cleaning: Wipe down the exterior with a damp cloth and mild soap. Avoid abrasive cleaners or harsh chemicals, as these can damage the resin material.
- Cushion Care: The cushion is waterproof. For cleaning, wipe with a damp cloth. If the inner sponge needs replacement, the cushion cover is designed to be removable.
- Weather Protection: While the deck box is waterproof and UV-resistant, prolonged exposure to extreme weather conditions may affect its appearance over time. Consider placing it in a shaded area or covering it during harsh weather for extended periods.
- Hinge Inspection: Periodically check the hydraulic hinges for smooth operation and ensure all screws remain tight.

Troubleshooting
- Lid not closing smoothly: Check the hydraulic hinges for any obstructions or loose screws. Ensure the box is on a level surface.
- Water inside the box: Verify that the lid is fully closed and properly sealed. Check for any cracks or damage to the resin material. Ensure the box is not placed in an area where water can pool around its base.
- Difficulty assembling: Ensure all pieces are correctly oriented and aligned before applying pressure. Listen for the 'click' sound to confirm panels are securely fastened. Refer to the assembly video for visual guidance.
