4. Operating Instructions
Once a model is assembled and the motor is connected to the battery box with batteries installed, you can operate your creation.
- Ensure all connections are secure and the model is stable.
- Locate the On/Off switch on the Battery Box.
- Flip the switch to the 'On' position to activate the motor and power the model.
- To stop the model, flip the switch back to the 'Off' position.
Important Note:
This kit allows for the construction of 58 different models, but only one model can be built and operated at a time, as it includes a single battery box and motor. If you wish to operate multiple models simultaneously, additional battery boxes and motors can be purchased separately.
5. Maintenance
Proper maintenance ensures the longevity and functionality of your building block kit.
- Cleaning: Wipe the building blocks and electronic components with a dry, soft cloth. Avoid using water or chemical cleaners, as these can damage the electronic parts.
- Storage: After use, disassemble models and store all pieces in the provided plastic storage box and tray to prevent loss and damage. Keep the kit in a cool, dry place away from direct sunlight.
- Battery Care: Remove batteries from the Battery Box if the kit will not be used for an extended period to prevent leakage and corrosion.
6. Troubleshooting
If your model is not functioning as expected, consider the following:
- Model Not Moving:
- Check if the Battery Box is switched to the 'On' position.
- Ensure batteries are correctly installed with the proper polarity and are not depleted. Replace if necessary.
- Verify that the motor is securely connected to the Battery Box.
- Inspect the model for any mechanical obstructions or incorrectly assembled parts that might be preventing movement.
- Motor Not Responding:
- Confirm the battery box has fresh batteries and is switched on.
- Ensure the motor cable is fully inserted into the battery box port.
- If the motor still does not respond, it may require replacement. Refer to the Warranty and Support section.
