Setup
- Unpack the Box: Carefully remove all contents from the product packaging.
- Review Instructions: Before beginning assembly, thoroughly read through the entire instruction booklet. Familiarize yourself with the diagrams and steps.
- Prepare Your Workspace: Choose a clean, well-lit, and spacious area for assembly. Ensure you have enough room to lay out all the cardboard sheets and work comfortably.
- Identify Pieces: The pieces are typically numbered or coded on the cardboard sheets. Identify the different sheets and the general layout of the pieces. Do not detach pieces until instructed or when they are needed for a specific step.
Operating (Assembly Instructions)
Follow the numbered steps in the instruction booklet and refer to the diagrams for visual guidance. The general process involves detaching pieces and interlocking them according to the design.
- Detaching Pieces: Gently push out the required pieces from their cardboard sheets. If a piece is difficult to remove, use a craft knife or scissors carefully (adult supervision recommended) to cut the small connecting tabs, ensuring not to damage the piece itself. No glue or additional tools are typically required for Cubic Fun puzzles.
- Follow Numerical Order: The instruction booklet will guide you through the assembly process step-by-step, usually in a numerical sequence. Ensure you connect pieces in the correct order to avoid structural issues.
- Interlocking: Most pieces will have tabs and slots. Align the tabs with the corresponding slots and gently push them together until they fit snugly. Do not force pieces, as this can cause damage.
- Building Sections: The model is often built in sections (e.g., hull, deck, masts, sails). Complete each section before attaching it to the main structure.
- Sails and Rigging: Pay close attention to the diagrams for attaching the sails and rigging components, as these often require precise placement for a realistic appearance.

Maintenance
- Cleaning: To clean the assembled model, gently dust it with a soft, dry cloth or a soft brush. Avoid using water or cleaning solutions, as these can damage the cardboard material.
- Storage and Display: Display your completed model in a stable, dry environment away from direct sunlight, excessive heat, or humidity to prevent warping or fading.
- Handling: Handle the model carefully, especially delicate parts like masts and rigging, to prevent accidental damage.
Troubleshooting
- Pieces Not Fitting:
- Ensure you are using the correct pieces for the current step. Double-check the piece numbers or shapes against the instruction diagrams.
- Verify the orientation of the pieces. Sometimes a piece may only fit in one specific direction.
- Do not force pieces. If a piece is very tight, gently wiggle it or check for any small cardboard burrs that might be obstructing the fit.
- Model Instability:
- Re-examine previously assembled sections to ensure all connections are secure and pieces are fully interlocked.
- Ensure the base or hull structure is correctly assembled and stable before adding upper sections.
- Missing Pieces:
- Carefully check all cardboard sheets and the packaging. Small pieces can sometimes get overlooked.
- If a piece is genuinely missing, contact CubicFun customer support (see Support section).
