New car and big car maintenance do not pay attention to the running-in period
Buying motorcycles and car maintenance, because the surface of the parts is not smooth, the geometrical appearance of the parts and the assembly line have the necessary errors. The friction parts are mainly used to touch the total area, and the work of the company touches the total area. The pressure is very high, the wear rate is increased rapidly, and the heat generated by the friction is relatively large. Therefore, care should be taken for the maintenance and maintenance of the new car and the large car and the running-in period should be given. Always limit the speed and load during the running-in, and immediately maintain and replace the grease. In fact, many new car buyers, especially those who are regular tricycle passengers, do not follow the instructions in the manual to maintain the car and maintain the car. Some of them drive over the mountains during the running-in period of the new car, speed limit, request timeout, overload operation, and the grease is not removed after thousands of kilometers of running-in, resulting in over-temperature of the diesel engine.
