4. Setup and Assembly

Assembly time is approximately 7 hours. Patience and attention to detail are crucial for a successful build.

4.1 Preparation

1. Clear Workspace: Prepare a clean, well-lit, and spacious work area.
2. Review Instructions: Carefully read through the entire assembly manual before detaching any pieces. Familiarize yourself with the steps and component identification.
3. Identify Parts: The wooden pieces are numbered. Match these numbers with the visuals in the manual.
4. Tools (Optional but Recommended): A small craft knife or sandpaper may be useful for smoothing edges or detaching pieces cleanly. Wood glue (not included) can be used for added stability on certain joints, but is generally not required.

4.2 Assembly Steps

Follow the step-by-step diagrams and instructions provided in the included physical manual. The general process involves:

1. Detaching Pieces: Gently push out the pre-cut wooden pieces from their sheets. If a piece is difficult to remove, use a craft knife to carefully cut the connecting points.
2. Sanding (Optional): Lightly sand any rough edges for a smoother fit and finish.
3. Connecting Components: Assemble pieces according to the numbered steps and diagrams. Pay close attention to the orientation of each piece.
4. Gears and Mechanisms: Ensure all gears and moving parts are assembled loosely enough to rotate freely, but securely enough to stay in place. Do not force connections.
5. Testing Movement: Periodically test the movement of sub-assemblies as you build to ensure proper function before proceeding to the next steps.

5. Operating Instructions

Once assembly is complete, your Marble Night City is ready for operation.

1. Place Marbles: Carefully place the provided steel marbles into the designated marble entry point, usually at the base of the lifting mechanism.
2. Crank the Handle: Locate the hand crank on the side of the model. Gently and steadily rotate the handle. This action powers the gear transmission system, which lifts the marbles to the top of the track.
3. Observe the Run: Watch as the marbles descend through the various tracks, spirals, and switches. The continuous rotation of the handle will create an "infinite cycle" of marble movement.
4. Smooth Operation: If marbles get stuck, stop cranking and gently dislodge them. Ensure all moving parts are free from obstruction.

6. Maintenance

• Cleaning: Use a soft, dry cloth or a small brush to gently remove dust from the wooden components and tracks. Avoid using water or chemical cleaners, as these can damage the wood.
• Storage: Store the assembled model in a dry environment, away from direct sunlight and extreme temperature changes, to prevent warping or damage to the wood.
• Lubrication (Optional): For smoother gear operation, a very small amount of dry lubricant (e.g., graphite powder) can be applied to gear teeth, but this is generally not necessary for typical use. Avoid oil-based lubricants.
• Check Connections: Periodically inspect all connections to ensure they remain secure. Re-seat any loose pieces if necessary.
