4. Assembly Instructions
Assembly requires patience and attention to detail. No glue is needed for the primary construction, as pieces interlock. Follow the numbered steps in the included manual and refer to the diagrams.
4.1. Preparation
- Unpack all components and lay them out on a clean, flat surface.
- Familiarize yourself with the instruction manual and the different wooden sheets.
- Carefully remove pieces from the wooden sheets. Use sandpaper for any rough edges if necessary.
4.2. Step-by-Step Assembly
The assembly process involves building the base, integrating the mechanical music box, constructing the gear system, and finally adding the astronomical meridian ring and planets.

- Base Construction: Begin by assembling the foundational layers of the music box base according to the numbered diagrams. Ensure all interlocking tabs are securely fitted.
- Gear System Assembly: Construct the internal gear mechanisms. Pay close attention to the orientation of each gear. Apply a small amount of wax to the gear teeth and axles to ensure smooth rotation.
- Music Box Integration: Carefully insert the mechanical music box module into its designated slot within the base structure. Connect any required linkages to the gear system.
- Astronomical Ring and Planet Assembly: Build the outer astronomical meridian ring. Attach the colorful beads, representing planets, to their respective arms or positions on the rotating mechanism. You can freely combine the planets as desired.
- Final Connections: Secure all upper structures and ensure all moving parts are free from obstruction. Test the rotation and music mechanism periodically during assembly to identify any issues early.

5. Operating Instructions
Once fully assembled, your Starry Night Mechanical Music Box is ready for operation.
5.1. Activating the Music and Rotation
- Locate the winding key on the side or bottom of the music box.
- Gently turn the winding key clockwise until you feel a slight resistance. Do not over-wind, as this can damage the mechanism.
- Release the key. The music box will begin to play its melody, which is typically 'Memory' from 'Cats', and the astronomical meridian ring with its planets will start to rotate.

6. Maintenance
To ensure the longevity and smooth operation of your mechanical music box, follow these maintenance guidelines:
- Cleaning: Dust the model regularly with a soft, dry cloth. Avoid using wet cloths or harsh cleaning agents, as these can damage the wood.
- Lubrication: If the gears or rotating parts become stiff, apply a small amount of the provided wax (or a similar dry lubricant) to the contact points. Do not use oil-based lubricants.
- Storage: Store the model in a dry environment, away from direct sunlight and extreme temperature fluctuations, to prevent warping or damage to the wood.
- Handling: Handle the assembled model with care, especially the delicate rotating parts. Avoid dropping or applying excessive force.
7. Troubleshooting
If you encounter any issues with your mechanical music box, refer to the following common problems and solutions:
- Music Box Not Playing/Rotating:
- Ensure the music box has been properly wound.
- Check for any obstructions in the gear mechanism or rotating parts.
- Verify that all parts are correctly assembled and securely fitted, especially the connection between the winding mechanism and the gears.
- Apply wax to the gears if they appear stiff.
- Parts Not Fitting:
- Ensure you are using the correct part for the step. Refer to the numbered diagrams.
- Gently sand any edges that are too tight using the provided sandpaper. Do not force pieces, as this can cause breakage.
- Warped or Damaged Parts:
- If a part is slightly warped, try to gently flatten it under a heavy object for a few hours.
- For broken parts, use the provided spare parts. If no spare is available, contact customer support.
