General JEKCA Building Method

- Use the provided pin driver to gently push the pin through the bricks until they are securely fastened.

Ensure all connections are firm to maintain the structural integrity of your model.
Operating Instructions
The JEKCA Grey Tabby Cat is an Automata Series model, meaning it incorporates a simple mechanical movement. Once fully assembled:
- Locate the small crank on the side of the base structure (as shown in Figure 2).
- Gently turn the crank clockwise or counter-clockwise.
- Observe the movement of the cat's tail, which is designed to wag when the crank is operated.
Avoid forcing the crank if you encounter resistance. Ensure all parts are correctly assembled and move freely.
Maintenance
To keep your JEKCA model in optimal condition:
- Cleaning: Dust the model regularly with a soft, dry cloth or a soft brush. For stubborn dirt, use a slightly damp cloth and dry immediately. Avoid harsh chemicals or abrasive cleaners.
- Storage: Store the model in a cool, dry place away from direct sunlight to prevent discoloration or material degradation.
- Handling: Always handle the model by its base to prevent accidental disassembly or damage to delicate parts.
