Setup and Assembly
Follow the step-by-step instructions provided in the included manual. Organize your blocks by type and color to facilitate the assembly process.
- Preparation: Clear a well-lit, flat workspace. Open all block bags and sort components.
- Base Construction: Begin by assembling the base structure as indicated in the manual. This forms the foundation for the mechanical system.
- Gear Mechanism Assembly: Carefully follow the diagrams to construct the intricate gear system that drives the planetary movements. Pay close attention to gear alignment.
- Planetary Bodies: Assemble the Sun, Earth, and Moon models using the designated blocks.
- Integration: Attach the planetary bodies to the gear mechanism, ensuring smooth rotation and revolution.
- Month Dial and Handle: Install the month dial and the operating handle.

Operating Instructions
The CaDA Master C71004W Orrery is designed to simulate the movements of the Earth, Moon, and Sun. Operate the model using the integrated handle.
- Turning the Handle: Locate the handle on the side of the base. Gently turn the handle clockwise to initiate the movements of the Earth and Moon around the Sun.
- Earth's Rotation: One full rotation of the Earth model represents approximately one day.
- Earth's Revolution: Turning the handle approximately 365 times will complete one full revolution of the Earth around the Sun, simulating one year.
- Moon's Revolution: The Moon model will revolve around the Earth. Approximately 30 turns of the handle will complete one revolution of the Moon around the Earth, representing one month.
- Month Dial: Observe the indicator on the month dial. As the Earth revolves, the indicator will pass through the names of the months, demonstrating the passage of time relative to the Earth's position in its orbit.

Image: A visual guide illustrating the operational mechanics of the orrery. It shows that one turn of the knob equals one Earth rotation (1 day), 365 turns equal one Earth revolution (1 year), 30 turns equal one Moon revolution (1 month), and how the indicator moves across the month dial.

Maintenance
To ensure the longevity and smooth operation of your Solar System Orrery, follow these maintenance guidelines:
- Cleaning: Use a soft, dry cloth to gently wipe dust from the model. Avoid using abrasive cleaners or solvents.
- Storage: Store the orrery in a cool, dry place away from direct sunlight and extreme temperatures to prevent material degradation.
- Handling: Always handle the model by its base. Avoid applying excessive force to the moving parts or planetary bodies.
- Loose Connections: Periodically check for any loose blocks or connections. Re-secure them firmly if found.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Planets not moving smoothly. | Gears misaligned or blocks not fully connected. | Check all gear connections and ensure blocks are firmly pressed together. Refer to assembly steps. |
| Handle is stiff or difficult to turn. | Friction in the gear system or a block obstructing movement. | Inspect the entire mechanism for any obstructions. Ensure no blocks are rubbing against each other. |
| Missing parts after unboxing. | Packaging error or small parts overlooked. | Carefully re-check all packaging materials. If parts are still missing, contact CaDA customer support. |
