Setup Instructions
- Prepare Your Play Area: Choose a flat, stable surface for building your marble run.
- Arrange Base Plates: Begin by placing the hexagonal base plates on your chosen surface. These form the foundation of your jungle track.
- Build Height with Blocks: Use the building blocks to create different height levels. Blocks can be stacked on top of the base plates or other blocks to form towers and supports for your tracks.
- Connect Tracks: Place the various track segments (straight, slope, large turn, small turn) between the elevated blocks to create a continuous path for the marbles. Ensure connections are secure.
- Integrate Action Elements: Position the start and finish elements at the beginning and end of your desired track. Incorporate special action elements like the hammer and rocker to add dynamic movement to your marble run.
- Decorate Your Jungle: Enhance your track with the 3D decoration elements and cardboard animal figurines to create a vibrant jungle environment. These elements are designed to fit into the open base blocks or directly onto the base plates.

Operating Instructions
Once your GraviTrax Junior marble run is assembled, follow these steps to operate it:
- Place a Marble: Carefully place one of the provided marbles into the designated start element at the beginning of your track.
- Observe the Path: Watch as the marble travels through the track, utilizing gravity and the various elements you have constructed.
- Experiment and Adjust: If the marble does not reach the finish, or if you wish to create a different path, adjust the placement of blocks and track segments. Experiment with different heights and angles to understand how they affect the marble's speed and direction.
- Utilize Action Elements: Observe how the hammer and rocker elements interact with the marble, adding unique movements and challenges to the track.

Maintenance
- Cleaning: To clean the GraviTrax Junior components, wipe them with a soft, damp cloth. Avoid using harsh chemicals or abrasive cleaners, as these may damage the materials. Ensure all parts are dry before storage.

Troubleshooting
- Marble Gets Stuck:
- Check for proper alignment of track segments. Ensure they are securely connected and form a smooth path.
- Verify that the height differences between blocks are sufficient to provide enough gravitational force for the marble to move.
- Ensure no decorative elements or other objects are obstructing the track.
- Track Sections Disconnect:
- Ensure blocks and track segments are placed firmly on the base plates or other blocks.
- Avoid excessive force during play that might dislodge components.
