Assembly Instructions
The JEKCA building system utilizes a patented interlocking brick-through system for sturdy construction. Follow these steps carefully:
Step 1: Understand the Interlocking System
JEKCA blocks are connected using pins that pass through the bricks, securing them firmly. This method ensures the completed model is robust and less prone to accidental disassembly.

Step 2: Basic Connection Procedure
Refer to the detailed instruction manual included in your kit for specific model assembly. The general connection steps are as follows:
- Align Blocks: Place the blocks you wish to connect in their designated positions according to the manual.
- Insert Pins: Insert the provided pins through the holes in the top block and into the corresponding holes of the bottom block.
- Secure with Pin Driver: Use the pin driver tool to turn the pins 90 degrees. This action expands the pin within the blocks, creating a secure, interlocking connection.

Step 3: Follow Model-Specific Instructions

Maintenance
To maintain the appearance of your JEKCA model, you may gently dust it with a soft cloth or brush. For deeper cleaning, use a slightly damp cloth with mild soap and water, then wipe dry immediately. Avoid harsh chemicals or abrasive materials, as these can damage the plastic blocks.
Troubleshooting
- Difficulty Connecting Blocks: Ensure the pins are correctly aligned and fully inserted before turning with the pin driver. Do not force connections.
- Loose Connections: If a connection feels loose, ensure the pin has been turned 90 degrees to fully engage the interlocking mechanism.
- Missing Parts: If you discover any missing components, please refer to the contact information in the Support section to request replacements.
- Model Instability: Double-check all connections in the affected area. Ensure all pins are securely fastened according to the instructions.
