4. Assembly Instructions (Setup)
The JEKCA building system utilizes a unique interlocking mechanism that ensures a strong and stable final model. Follow the detailed step-by-step instructions provided in the included instruction manual for precise assembly.
4.1 Key Assembly Principle: The Interlocking System
Unlike traditional building blocks, JEKCA models are secured using pins that pass through the bricks, locking them together. This method eliminates the need for glue and provides superior structural integrity.

4.2 Step-by-Step Assembly
- Preparation: Unpack all components and organize the bricks by color or shape as suggested in the instruction manual.
- Follow the Manual: Refer to the comprehensive instruction manual for the exact sequence of brick placement and pin insertion. Each step is illustrated to guide you.
- Insert Pins: When instructed, align the bricks and insert the provided pins through the designated holes.
- Secure with Pin Driver: Use the pin driver tool to turn the pins 90 degrees. This action locks the bricks firmly in place. Ensure each pin is fully turned for maximum stability.
- Layer by Layer: Continue building layer by layer, ensuring each section is securely interlocked before proceeding.
- Final Touches: Once the main structure is complete, attach any remaining decorative pieces as per the manual.

5. Operating (Building Process)
The "operation" of your JEKCA Chameleon 01S involves the careful and precise assembly of its components. The unique interlocking system is central to this process, providing both structural integrity and a satisfying building experience.
Focus on aligning each brick correctly and ensuring that the pins are fully inserted and turned. This attention to detail during the building phase will result in a robust and aesthetically pleasing final model. The process is designed to be intuitive, with the included manual serving as your primary guide.

6. Maintenance
Once assembled, your JEKCA Chameleon 01S model requires minimal maintenance. Follow these guidelines to preserve its appearance and structural integrity:
- Cleaning: To remove dust, gently wipe the model with a soft, dry cloth. For more stubborn dirt, a slightly damp cloth can be used, but avoid excessive moisture. Do not use harsh chemicals or abrasive cleaners.
- Storage: Store the model in a stable location away from direct sunlight, extreme temperatures, and high humidity, which can affect the plastic over time.
- Handling: While the model is sturdy, avoid dropping it or applying excessive force, as this could dislodge bricks or pins.
7. Troubleshooting
Should you encounter any issues during assembly or with the completed model, consider the following:
- Bricks Not Fitting: Ensure you are using the correct bricks for each step as indicated in the manual. Sometimes, similar-looking bricks have subtle differences.
- Loose Connections: If a section feels loose, verify that all pins in that area are fully inserted and turned 90 degrees with the pin driver. A partially turned pin will not secure the bricks properly.
- Missing Pieces: Double-check the packaging and work area. If a piece is genuinely missing, refer to the support section for contact information.
- Difficulty with Pin Insertion: Ensure the holes in the bricks are perfectly aligned before attempting to insert a pin. Do not force pins; gentle pressure and correct alignment are key.
