How should the winter dining car be maintained?
               First of all, the tire of the food truck should not be too much, increase the area of the tire and the road to avoid slipping; when driving, try to move the center of gravity down, do not brake sharply.
       The road surface is slippery in winter, and the center of gravity does not move down. When braking, it is easy to draw a lot forward, resulting in accidents.
       The second is that the power of the dining car should be sufficient, and the battery should be fully charged every night. Do not leave the battery idle for a long time, which can increase the life of the battery.
