3. Safety Information
- Age Recommendation: This 3D puzzle is recommended for ages 14 and up due to the complexity and presence of small parts. Adult supervision is advised for younger builders.
- Small Parts Warning: The kit contains small pieces that may pose a choking hazard. Keep out of reach of small children.
- Handling: Handle wooden pieces with care. Some parts are delicate and can break if excessive force is applied.
- Batteries: If your model includes LED lights, ensure batteries are inserted correctly according to polarity markings. Do not mix old and new batteries or different types of batteries. Dispose of used batteries responsibly.
4. Setup
- Unpack the Kit: Carefully remove all contents from the packaging.
- Inspect Components: Check all plywood sheets and accessories against the parts list in your included instruction manual to ensure all pieces are present and undamaged.
- Prepare Workspace: Set up a clean, well-lit, and spacious work area. A flat, stable surface is essential for assembly.
- Tools: No additional tools are typically required, as pieces are designed to interlock. However, a small piece of sandpaper (often included) can be used to smooth edges if needed.
5. Assembly Instructions
Follow the detailed, step-by-step instructions provided in the separate printed manual included with your kit. The assembly process involves carefully detaching pieces from the plywood sheets and interlocking them according to the diagrams.
- Detaching Pieces: Gently push out the laser-cut pieces from their sheets. If a piece is stubborn, use a small, blunt object to carefully push it out from the back. Avoid tearing or forcing.
- Interlocking: Align the tabs and slots of corresponding pieces and gently press them together. Some connections may require a firm but controlled push. If a connection is too tight, use the included sandpaper to lightly smooth the edges of the tabs.
- No Glue Required: This model is designed for interlocking assembly without the need for adhesive.
- Sequence: Adhere strictly to the numbered steps in the instruction manual. Assembling pieces out of sequence may lead to difficulties or damage.
