3. Setup and Assembly
The JEKCA T-Rex model utilizes a special interlocking brick-through system for sturdy construction. Follow these steps carefully for assembly.
Understanding the JEKCA Interlocking System
JEKCA blocks are designed to interlock securely using pins and a pin driver. This system ensures the finished model is robust and less prone to falling apart.

General Assembly Steps
- Unpack Components: Carefully remove all bricks, pins, and the pin driver from the packaging. Organize bricks by color or type if helpful.
- Consult the Manual: Refer to the included detailed building manual for step-by-step instructions specific to the T-Rex 02S-M02 model. The manual will guide you through each layer and section of the dinosaur.
- Connect Blocks: As shown in Figure 3.1 and 3.2, align the blocks according to the manual. Insert the provided pins into the designated holes.
- Secure Connections: Use the pin driver to turn each inserted pin 90 degrees. This action expands the pin within the blocks, creating a strong, secure connection.
- Layer by Layer Construction: Build the model layer by layer, ensuring each section is firmly connected before proceeding. Pay close attention to the orientation of each block.
- Final Touches: Once all sections are assembled, double-check all connections to ensure the model is stable and complete.

5. Maintenance
To keep your JEKCA T-Rex model in optimal condition, follow these simple maintenance guidelines:
- Cleaning: Dust the model regularly with a soft, dry cloth or a soft brush. For more stubborn dirt, a slightly damp cloth can be used, but avoid excessive moisture.
- Avoid Direct Sunlight: Prolonged exposure to direct sunlight may cause the plastic colors to fade over time. Display the model in a location away from direct sun.
- Handle with Care: While sturdy, avoid dropping the model or applying excessive force, which could dislodge blocks or pins.
6. Troubleshooting
If you encounter any difficulties during assembly or with your finished model, consider the following:
- Difficulty Following Instructions: The assembly process can be intricate due to the high number of pieces. Take your time, review each step in the included building manual carefully, and ensure correct block orientation and pin insertion. Sometimes, taking a break and returning with fresh eyes can help.
- Loose Connections: Ensure that all pins are fully inserted and turned 90 degrees with the pin driver. A properly turned pin will create a secure, tight connection.
- Missing Pieces: Double-check your packaging and work area. If you believe a piece is genuinely missing, refer to the support section for contact information.
