6. Maintenance

To ensure the longevity and smooth operation of your Marble Night City Marble Run, follow these maintenance guidelines:

• Cleaning: Use a soft, dry cloth to gently wipe dust from the wooden surfaces. Avoid using water or cleaning solutions, as they may 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.
• Inspection: Periodically inspect all connections and moving parts to ensure they are secure and free from obstruction.
• Lubrication: The mechanical gears are designed for smooth operation without lubrication. Do not apply oils or greases, as this may attract dust and hinder performance.

7. Troubleshooting

If you encounter issues with your Marble Night City Marble Run, refer to the following common problems and solutions:

• Marbles Stop or Slow Down:
  • Cause: Ramps or tracks may not have the correct slope, or there might be friction points.
  • Solution: Carefully inspect the entire marble path. Ensure all track pieces are fully seated and aligned according to the instruction booklet. Verify that the base is on a level surface. Slight adjustments to the model's tilt by placing thin pads under the rear feet can sometimes improve marble flow if the issue persists after verifying assembly.
• Upper Teetertotter Malfunction:
  • Cause: The teetertotter mechanism may not be assembled correctly or is obstructed.
  • Solution: Re-examine the assembly of the upper teetertotter section using the instruction booklet. Ensure all pivot points are free-moving and that no pieces are binding. Verify that marbles are correctly triggering the mechanism.
• Gears Not Turning Smoothly:
  • Cause: Gears may be misaligned, obstructed, or too tightly assembled.
  • Solution: Check all gear connections for proper alignment. Ensure no foreign objects are caught between the teeth. If screws are used, ensure they are not overtightened, allowing for free rotation.
