4. Operating Instructions
The Gravity Marble Run is powered by an electric motor that requires 4 AA 1.5V batteries (not included). Once assembled and batteries are installed, the motor lifts the marbles from the bottom to the top of the structure, allowing gravity to guide them down through the various tracks.
- Battery Installation: Locate the battery compartment, typically at the base of the model. Insert 4 AA 1.5V batteries, ensuring correct polarity.
- Power On/Off: Use the designated switch (refer to the assembly guide for exact location) to turn the motor on or off.
- Marble Placement: Place the provided glass marbles into the designated entry point at the base of the marble run. The lifting mechanism will then transport them upwards.

5. Maintenance
To ensure the longevity and smooth operation of your Wood Trick Gravity Marble Run, consider the following maintenance tips:
- Cleaning: Dust the model regularly with a soft, dry cloth. Avoid using water or cleaning solutions, as they may damage the wood.
- Lubrication: For optimal performance, especially for gears and sliding surfaces, apply a small amount of wood-safe lubricant (e.g., paraffin wax or specialized woodworker's slipit) using a small brush. This can reduce friction and noise.
- Storage: Store the model in a dry environment away from direct sunlight or extreme temperature changes to prevent warping or cracking of the wood.
- Handling: Handle the assembled model with care, especially when moving it, to avoid dislodging or damaging delicate parts.
6. Troubleshooting
If you encounter issues with your Gravity Marble Run, refer to the following common problems and solutions:
- Marbles not moving smoothly or getting stuck:
- Check for any misaligned track pieces. Small adjustments can significantly improve flow.
- Ensure all connections are secure and no parts are loose.
- Apply lubricant to tracks and moving parts as described in the Maintenance section.
- Marbles bouncing out of tracks:
- Inspect the specific sections where marbles are bouncing. Some users have found that adding a small, custom-made taller rail from scrap wood can prevent this in certain areas (e.g., Part #152 Page 36, if applicable to your model's instructions).
- Ensure the model is on a stable, level surface.
- Motor not operating or making unusual noises:
- Verify that the batteries are correctly installed and have sufficient charge. Replace if necessary.
- Check for any obstructions preventing the motor or gears from turning freely.
- Ensure the motor is securely attached and has not come loose from its mounting. If it has, carefully re-secure it to prevent damage to wooden pieces.
