6. Care and Maintenance

To ensure the longevity and optimal performance of your Mould King Rotary Engine Model Kit, follow these simple care and maintenance guidelines:

• Cleaning: Dust the model regularly with a soft, dry cloth. For stubborn dirt, a slightly damp cloth can be used, but ensure no moisture enters the electrical components.
• Storage: Store the model in a cool, dry place away from direct sunlight and extreme temperatures.
• Battery Removal: If the model will not be used for an extended period, remove the battery from the battery box to prevent leakage and damage.
• Component Check: Periodically inspect all connections and moving parts to ensure they are secure and free from obstruction.

7. Troubleshooting

If you encounter any issues with your model, refer to the following troubleshooting tips:

7.1. Engine Does Not Run

• Check Battery: Ensure the battery is correctly installed with the proper polarity and is not depleted. Replace if necessary.
• Power Switch: Verify that the power switch on the battery box or motor is in the 'ON' position.
• Connections: Inspect all electrical connections between the motor, battery box, and any wiring. Ensure they are firmly connected.
• Obstructions: Check for any building blocks or foreign objects that might be obstructing the movement of the gears or rotors.

7.2. Gears Are Stiff or Jammed

• Recheck Assembly: Carefully review the assembly steps related to the gear mechanism. Incorrect placement of even one piece can cause jamming.
• Lubrication: While not typically required for building blocks, ensure no dust or debris is interfering with gear movement.
