5. Operating Instructions
After successful assembly, follow these steps to operate your models:
- Insert Batteries: For models requiring battery power (Four-wheel Drive, Tank, Wind-powered Vehicle, Off-road Vehicle, Biplane), insert 2 AA batteries into the designated battery compartment. Ensure correct polarity.
- Solar Helicopter: Place the Solar Helicopter in direct sunlight. The solar panel will convert light into electrical energy to power the rotor.
- Activate: Locate the power switch on your model (if applicable) and turn it to the 'ON' position.
- Observe: Watch your model in action. For vehicles, ensure they are on a flat, clear surface.
6. Maintenance
To ensure the longevity and proper functioning of your Yutin STEM Kits, consider the following maintenance tips:
- Cleaning: Wipe wooden parts with a dry, soft cloth. Avoid using water or harsh chemicals, which can damage the wood.
- Storage: Store models in a dry place away from direct sunlight and extreme temperatures to prevent warping or damage to electronic components.
- Battery Care: Remove batteries from models if they will not be used for an extended period to prevent leakage.
- Component Check: Periodically check screws and connections to ensure they remain tight. Re-tighten if necessary.
7. Troubleshooting
