4. Assembly Instructions
The JEKCA building system uses a unique interlocking mechanism to create highly stable and detailed models. Follow the steps below for proper assembly.
4.1. Understanding the Interlocking System
Each JEKCA brick is secured using pins that pass through the bricks and are then rotated to lock them in place. This creates a strong, durable connection.

4.2. Step-by-Step Assembly Process
Refer to the detailed instruction manual included in your box for the specific sequence of brick placement. The general process involves three main steps:
- Connect Bricks: Align the studs of one brick with the holes of another.
- Insert Pins: Insert the provided pins through the designated holes in the connected bricks.
- Lock Pins: Use the pin driver to turn each pin 90 degrees. This action expands the pin within the bricks, creating a secure and permanent connection.

Proceed through the included manual page by page, carefully following the diagrams and instructions for each section of the Rainbow Lorikeet model. Ensure each pin is fully inserted and turned to achieve maximum stability.
5. Maintenance
Once assembled, your JEKCA model requires minimal maintenance. To keep your Rainbow Lorikeet looking its best:
- Cleaning: Dust the model regularly with a soft, dry cloth or a soft brush. For deeper cleaning, gently wipe with a damp cloth and mild soap, then dry immediately. Avoid harsh chemicals or abrasive materials.
- Storage: Store the model in a stable location away from direct sunlight and extreme temperatures to prevent discoloration or material degradation.
- Handling: While sturdy, avoid dropping or applying excessive force to the model to prevent damage to the interlocking connections.
6. Troubleshooting
If you encounter any issues during assembly or with your finished model, consider the following:
- Missing Pieces: Double-check all packaging and sorting trays. If a piece is genuinely missing, contact JEKCA customer support with details of the missing part (shape, color, quantity).
- Difficulty Connecting Bricks: Ensure bricks are correctly aligned before attempting to insert pins. Apply firm, even pressure. If a pin is difficult to turn, ensure it is fully inserted before rotating with the pin driver.
- Model Instability: Review the assembly steps for the affected section. Ensure all pins are correctly inserted and fully turned 90 degrees to lock the bricks securely.
- Disassembly: JEKCA models are designed for permanent assembly. Disassembly is generally not recommended as it may damage the pins or bricks.
