5. Operating Instructions
Each DECOOL Mini Pull Back Car is equipped with a simple pull-back mechanism:
- Place the assembled car on a flat, smooth surface.
- Gently pull the car backward, applying slight pressure. You will feel the internal mechanism winding up.
- Release the car, and it will zoom forward on its own.
Avoid pulling the car back excessively or forcing the mechanism, as this may cause damage.
6. Maintenance
- Cleaning: To clean the blocks, wipe them with a soft, damp cloth. Do not use harsh chemicals or abrasive cleaners.
- Storage: Store the blocks and assembled models in a cool, dry place away from direct sunlight to prevent discoloration or warping.
- Handling: Handle the assembled models with care to prevent pieces from detaching. If a piece comes loose, simply reattach it.
7. Troubleshooting
- Blocks not fitting: Ensure you are using the correct blocks as indicated in the instruction manual for your specific model. Apply gentle, even pressure when connecting blocks.
- Pull-back mechanism not working: Check if the wheels are properly attached and can rotate freely. Ensure no blocks are obstructing the internal mechanism. If the mechanism is damaged, it may need replacement.
- Missing pieces: Double-check all packaging materials. If pieces are genuinely missing, contact customer support with your purchase details.
