Carrera Car Racing Brushing grinders 6 Volt

About Car Racing:

Install the grinders with the curved side towards the car.

Furthermore, the rails should be freed from dust before use of the web, as the grinders wear off more quickly due to dust particles and no longer have proper contact with the rail. Cleaning the grinder is required when the ends are dark (burnt dust). Remove the grinder and with the left hand grasp the grinder on the strand and with the right thumbnail and forefinger remove the burned residue. You can also use a toothbrush and brush the wire slightly. The grinders are only suitable for vehicles with 6 volts.
