Setup and Assembly

- Prepare the Area: Choose a flat, level outdoor surface for the sandbox. Clear any debris or sharp objects.
- Lay the Ground Fabric: Place the provided weed-proof fabric on the chosen spot. This will prevent weeds from growing through the sand and keep the sand clean. Secure the fabric to the ground or the bottom of the sandbox frame if possible.
- Assemble the Sandbox Frame: Connect the wooden panels to form the main sandbox frame using the provided screws. Ensure all connections are tight and stable.
- Attach the Benches: Assemble the two foldable benches according to the instructions. Attach them to the sandbox frame using the hinges. Ensure the hinges allow for smooth opening and closing.
- Fill with Sand: Once the frame and benches are securely assembled, fill the sandbox with approximately 180 kg of clean play sand. Do not overfill.
- Final Check: Verify that all components are correctly assembled and all fasteners are tightened.

Operating Instructions
- Opening the Sandbox: Gently lift the foldable benches outwards to reveal the sand play area. The benches will serve as seating for children.
- Closing the Sandbox: When play is finished, fold the benches inwards until they meet in the middle, forming a complete cover over the sand. This protects the sand from rain, leaves, and animals.
- Using the Protective Tarp: For additional protection, especially during extended periods of non-use or adverse weather, place the provided blue tarp over the closed sandbox.

Maintenance
- Cleaning: Regularly clean the wooden surfaces with a damp cloth. Avoid harsh chemicals that could damage the wood or be harmful to children.
- Sand Care: Periodically rake the sand to aerate it and remove any foreign objects. Replace the sand if it becomes contaminated or excessively dirty.
- Wood Treatment: Although the wood is treated, periodic re-treatment with a child-safe wood sealant or stain is recommended to prolong its lifespan and maintain its appearance, especially in harsh weather conditions.
- Inspection: Regularly inspect all wooden parts for splinters, cracks, or signs of wear. Check all screws and hinges for tightness and re-tighten as needed.
- Winter Storage: During winter months or prolonged periods of non-use, it is advisable to cover the sandbox with the protective tarp or store it in a sheltered area to protect it from extreme weather.

- Missing Parts: If any parts are missing upon delivery, please contact KOTARBAU customer support immediately for assistance.
- Difficulty in Assembly: Ensure you are following the instructions step-by-step. Verify that all pieces are oriented correctly. If issues persist, refer to the assembly video or contact support.
- Loose Components: Regularly check and tighten all screws and fasteners to ensure the sandbox remains stable and safe.
