3. Setup
Proper setup of your slot car and track is crucial for optimal performance and enjoyment. Follow these steps to prepare your MR-C73 Bugatti Divo for racing:
- Track Assembly: Ensure your AGM MASTECH MR Series 1:64 HO Scale Slot Car Set track is fully assembled according to its specific instruction manual. Verify that all track interfaces are tight and flat to ensure continuous electrical contact and smooth car movement.
- Power Connection: Connect the power adapter to the track's control box and plug it into a suitable power outlet. Ensure the control box is switched on.
- Controller Connection: Plug the controllers into the designated ports on the control box.
- Car Placement: Carefully place the MR-C73 Bugatti Divo slot car onto the track. Ensure the guide rod (pin) on the underside of the car is aligned and inserted into the middle groove of the track. The brush blades should make firm contact with the track's metal strips.
- Check Contact Brushes: Verify that the conductive brushes (double contact brushes) on the underside of the car are at an angle of approximately 30 degrees to the rear of the vehicle. This ensures proper electrical pickup and stability.

5. Maintenance
Regular maintenance ensures the longevity and optimal performance of your slot car. Follow these tips for proper care:
- Conductive Brush Angle: Periodically check that the conductive brushes are at an angle of approximately 30 degrees to the rear of the vehicle. Adjust if necessary to ensure good contact with the track.
- Track Interface: Always ensure that all interfaces of the track are tight and flat. Loose connections can lead to power interruptions and poor performance.
- Brush Blade Contact: Confirm that the brush blade contacts the track metal strip firmly and that the car's wheels are flat with the track surface.
- Clean Track and Car: Keep both the track and the car's underside clean from dust and debris, which can interfere with electrical conductivity and smooth operation.
