Step-by-Step Assembly
Follow the detailed building manual included in your package. The manual provides visual, step-by-step instructions for constructing your JEKCA Cat 11S-M03 model. The general interlocking technique is as follows:
Basic Interlocking Technique
- Identify Components: Locate the correct blocks and pins as indicated in your building manual for each step.
- Align and Insert: Align the blocks precisely and insert a pin through the designated holes, ensuring it passes through both blocks.
- Secure Connection: Use the provided pin driver to turn the pin 90 degrees. This action locks the blocks securely in place, creating a strong bond.
- Repeat: Continue this process for all connections, ensuring each block is firmly attached according to the manual's instructions.

Maintenance
To clean your assembled JEKCA model, gently wipe it with a dry or slightly damp cloth. Avoid using harsh chemicals, abrasive materials, or excessive water, which may damage the plastic or compromise the structural integrity. Store the model in a cool, dry place away from direct sunlight to prevent discoloration.
Troubleshooting
Model Instability
If your assembled model feels unstable or parts are loose, carefully re-examine the connections. Ensure all pins are fully inserted and turned 90 degrees to securely lock the blocks. Refer to the building manual for specific connection points and double-check any complex sections.
