How to use: First, set up the racetrack by connecting the straights, curves, and guardrails together. Place the cars on the track and connect the speed controllers. You can start the race by using the controllers, and press the turbo - button for a speed boost. The lap counter will keep track of your laps. Note: Make sure the track is placed on a flat and stable surface. Keep small parts away from children under 3 to avoid choking hazards. Maintenance: Regularly clean the track with a soft cloth to remove dust. Check the cars' wheels and motors for any damage and replace parts if necessary.
