5. Maintenance
To ensure the longevity and appearance of your JEKCA Great Dane model:
- Cleaning: Dust the model regularly with a soft, dry cloth or a soft brush. For more stubborn dirt, gently wipe with a slightly damp cloth and then dry immediately. Avoid harsh chemicals or abrasive cleaners.

6. Troubleshooting
- Difficulty Interlocking Bricks: Ensure the pins are correctly aligned with the holes and that you are using the pin driver to rotate them 90 degrees. Do not force connections.
- Missing Pieces: Double-check all packaging and sorting areas. If pieces are genuinely missing, refer to the warranty and support section for contact information.
- Confusing Instructions: The included instruction manual is the primary guide. Pay close attention to the visual diagrams and the number of studs on each brick shown. Sometimes, colors in printed instructions can be challenging to distinguish; focus on shapes and counts.
