Key Assembly Steps:
- Prepare Your Workspace: Ensure a clean, well-lit area with enough space to sort pieces and follow the instructions.

- Secure Connections: Use the provided pin driver tool to insert the pins through the designated holes in the bricks. Turn the pin 90 degrees to lock the bricks firmly in place. This creates a sturdy structure that is not easily disassembled.

Operating (Building Process)
The "operation" of this product is the building process itself. It is designed to be a detailed and engaging project. Take your time and enjoy the process of bringing the French Bulldog model to life.
- Patience is Key: Due to the number of pieces and the intricate interlocking system, assembly requires patience and attention to detail.
- Verify Each Step: Double-check each step against the instruction manual before proceeding to ensure correct placement and secure connections.
- Enjoy the Craft: The reward is a sturdy and aesthetically pleasing model.
Maintenance
Once assembled, your JEKCA French Bulldog model requires minimal maintenance.
- 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.
- Storage/Display: Display the model on a stable surface away from direct sunlight to prevent potential fading of colors over time.
- Disassembly: While the interlocking system is designed for sturdiness, the model can be disassembled if needed. Carefully use the pin driver tool to unlock and remove the pins.
Troubleshooting
If you encounter any issues during assembly, consider the following:
- Missing Pieces: Carefully check all packaging and your workspace. If pieces are genuinely missing, contact JEKCA customer support.
- Difficulty Connecting Bricks: Ensure the pins are fully inserted and turned 90 degrees. Apply gentle, even pressure. Do not force pieces together.
- Unstable Structure: Re-examine the most recently assembled sections. An unstable structure often indicates a pin that is not fully locked or a brick placed incorrectly. Refer back to the instruction manual.
- Pins Breaking: Ensure you are using the pin driver tool correctly and not applying excessive force. If pins break, contact JEKCA customer support for replacements.
