1、 Excessive hot car
No matter in winter or other seasons, many car owners are used to taking the way of idle hot car in situ, hot car for a period of time and then driving, feel that the self loading concrete mixer, when the performance is good. But in fact, the effect of hot car idling in place is not only limited, but also a waste of gasoline and time. When the engine is under no load, the temperature climbing is quite slow, that is to say, it takes a long time for the engine to reach the normal working temperature at idle speed. The correct way to do it is to load the concrete mixer truck, heat the truck in place for about 30 seconds, and then drive on the road immediately. However, because the engine and drive system have not reached the normal working temperature at this time, the speed should still be controlled within about 2000 rpm, and the high speed operation can only be started after the water temperature reaches normal.
2、 Use of electrical equipment after flameout
Once the self loading concrete mixer is turned off, the battery will be in the working state of discharging without charging. Therefore, if you still use the high-power electrical appliances in the car after a long time of flameout, such as driving the headlights, parking at the roadside and listening to music for a long time, it may soon lead to the serious consequences of complete discharge of the battery, failure to start the self charging concrete mixer.
3、 Fill the tank after it bottoms out
Some people are lazy, others seldom pay attention to the fuel tank scale, and they will drive a certain distance to refuel until the fuel tank warning light is on. However, sometimes when you go to a gas station after the fuel warning light is on, there may be no gas station nearby and you will be in a hurry. And often such a case, since the feeding concrete mixer, the life of the pump may be greatly reduced.
