Maintenance
To keep your JEKCA Buffalo 01S model in excellent condition:
- Cleaning: Dust the model regularly with a soft, dry cloth or a soft brush. For more thorough cleaning, gently wipe with a slightly damp cloth and then dry immediately. Avoid harsh chemicals or abrasive cleaners.
- Storage: If disassembling for storage, keep all bricks, pins, and the pin driver in a secure container to prevent loss. Store in a cool, dry place away from direct sunlight to prevent material degradation or discoloration.
- Handling: Always lift the model from its base or sturdy sections to avoid putting stress on individual brick connections.
Troubleshooting
If you encounter any issues during assembly or with the finished model, consider the following:
- Loose Connections: Ensure all pins are fully inserted using the pin driver. Sometimes a pin may not be pushed all the way through, leading to a loose connection.
- Missing Pieces: Double-check the packaging and your work area. If a piece is genuinely missing, refer to the support section for assistance.
- Difficulty Fitting Bricks: Ensure you are using the correct bricks and following the manual's orientation. Some connections may require a firm, but gentle, push. Do not force pieces together.
- Model Instability: Review previous steps in the instruction manual to confirm all connections are correctly made and pins are fully secured. The interlocking system is designed for stability, so instability usually indicates an assembly error.
