4. Setup Instructions
Assembly is required for this playset. Follow these steps carefully:
- Unpack Components: Carefully remove all pieces from the packaging and lay them out on a clean, flat surface.

- Connect Track Supports: Attach the track supports/risers to the designated points on the mountain structure and base track pieces. These elevate sections of the track.
- Lay Out the Track: Begin connecting the track pieces. The playset features a long track, a switch point, and a section leading to the jump. Ensure each track piece clicks firmly into place. Refer to the overall layout shown in Image 2 for guidance.
