When a newly purchased refrigerated truck is used, the chassis must be repaired within the time specified in the maintenance manual. The maintenance of the chassis is generally carried out at the corresponding chassis service station in the local area. Then how should the first maintenance be maintained and which parts need to be "protected"? To start from the following four aspects. 1, refrigerated car engine When driving a new car, you can keep the engine idle and listen for strange sounds or vibrations. Because the problem of running the engine of an automobile has been delayed for a long time, it will accelerate wear, increase fuel consumption, shorten life, and eventually lead to overhaul. Refrigerated car engine maintenance method: The best way to protect the car's "heart" is to avoid emergency acceleration or deceleration during the running-in of the new car so as to minimize the load on the vehicle engine drive system. Some of the more serious and cautious old drivers take the initiative to send the car to repair and maintenance after driving for 1,000 kilometers. At this time, the maintenance is usually free of charge, and it can also avoid many potential problems in the meantime. This is a good thing that can serve two purposes. Don't miss it. 2, the paint car refrigerator A good appearance of a refrigerated truck reflects a fine degree of work, just as every day we have to take good care of our own skin, as well as the paint of a refrigerated truck. Although there is no aging problem in new paint finishes, from the factory to the transportation To the parking lot, the paint on the surface of the car has been exposed to the air, and it has been affected by sandstorms. The timely and correct maintenance will enable the car to remain young. Refrigerated car paint surface maintenance methods: to the new car "bath" must not be sloppy, such as improper cleaning, will damage the outer part of the oil, it will lead to the car's skin "dimmed". It is best to use neutral mild detergent to remove the sand and dirt from the paint surface. Some dirt is invisible to the naked eye. Contaminated with chemical components such as lacquer and gum, it must be wiped with a special detergent. Finally, apply appropriate protective agents on tires, bumpers, and eyebrows to prevent aging.
