Setup
Follow these steps to assemble your Hot Wheels Track Builder Unlimited Split Loop Pack:
- Connect Track Pieces: Begin by connecting the straight track pieces to form the approach to the launcher. Ensure the blue connectors are securely slotted into the track ends.
- Assemble the Launcher: Attach the launcher unit to the end of the initial straight track. The launcher features a slider mechanism to propel the car.

Troubleshooting
If you encounter any issues with your Hot Wheels Track Builder Unlimited Split Loop Pack, refer to the following common problems and solutions:
