Although the general maintenance and repairing methods of mobile sales vehicles are all the same, the maintenance of good and bad is also related to the use of the vehicle. However, there are maintenance skills in some details for different seasons, such as in the winter season. There are several tips for the maintenance of mobile vending trucks:
1. The antifreeze of a mobile sales truck is capable of preventing freezing and cooling. In areas with relatively low temperatures in the north, antifreeze should be replaced with low-temperature resistance to avoid the effect of cooling the mobile vending engine after freezing, or even damage the tank and the engine. In addition, under normal circumstances, the use cycle of anti-freeze agents for mobile trucks is generally between two and three years, and must be replaced immediately after the expiration of the service period.
2. The tires must be used in the driving process of mobile sales vehicles. Otherwise, what a good performance mobile sales vehicle would be is scrap iron. If the ice and snow frost on the driving surface is serious, then you need to replace the winter snow tires. This type of vehicle tires are sometimes more useful than four-wheel drive plus four seasons. In relatively cold weather, the tires and rubber of mobile vending trucks will harden. This time, it must be noted whether the tires have experienced aging. If the tires have a relatively serious degree of aging, or if they have appeared. In the case of a broken tread, it is extremely important to replace the new tire immediately.
3. The demand for lubricants for mobile vending trucks in winter is very high. If driving mobile vending trucks in the north, then the special oil for winter should be replaced. Oil is generally numbered. For example, the smaller the value in front of W with 5W30 and 0W40, the better the flow performance when the lubricant is in low temperature conditions. The lower the annual oil will be, the lower the oil will be. Therefore, the starting speed of the engine of the vehicle becomes larger. And the lower the pour point of the vending machine oil, the better the position where it can be lubricated, the harder friction is reduced. If the temperature is not very cold, the use of 5W engine oil is more appropriate.
Because the temperature in the winter nights continues to fall, after the mobile vending truck has experienced outdoor nights, the wiper is likely to freeze on the front windshield. Use warm air to properly thaw the wipers. Do not use boiling water to forcibly thaw them. When stopping a mobile wagon in the evening, a clean towel can be used to prevent the middle of the early glass and wiper from freezing.
