4. Maintenance
To keep your JEKCA Fox 01S model in excellent condition, follow these simple maintenance guidelines:
- Cleaning: Gently dust the model regularly with a soft, dry cloth or a soft brush. For more stubborn dirt, lightly dampen a cloth with water (no harsh chemicals) and wipe carefully. Ensure the model is completely dry afterward.
- Storage: If you need to store the model, place it in a secure container to protect it from dust and potential damage.
- Avoid Direct Sunlight: Prolonged exposure to direct sunlight may cause the plastic colors to fade over time.
5. Troubleshooting
If you encounter any issues during assembly or with your completed model, consider the following:
- Model Falling Apart: Ensure all pins are fully inserted and turned 90 degrees with the pin driver as instructed. Incomplete pin insertion is the most common cause of instability. Refer back to the assembly steps in your manual.
- Missing Pieces: Carefully check all packaging materials. If pieces are genuinely missing, contact JEKCA customer support (see Section 7).
- Difficulty with Pin Insertion: Ensure you are using the pin driver correctly. Apply firm, even pressure, and then turn 90 degrees. Do not force pins if they are misaligned.
