1、 Excessive hot car
No matter in winter or other seasons, many car owners are used to idling in situ to warm up the car. After a period of hot driving, they feel that the self loading concrete mixer has good performance. But in fact, idling in place is not only limited, but also a waste of gasoline and time. When the engine is in the state of no load, the temperature climb is very slow, that is to say, it takes a long time for the engine to reach the normal operating temperature at idle speed. The correct way should be from the loading concrete mixer, hot-rolled in place for about 30 seconds, and then immediately drive on the road. However, since the engine and drive system have not reached the normal operating temperature at this time, the speed should still be controlled within about 2000 rpm. After the water temperature reaches normal, the high-speed operation can be carried out.
2、 Use electrical equipment after flameout
Once the concrete mixer from the loading, flameout, the battery is in the working state of discharge 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 vehicle's headlights, parking on the roadside and listening to music for a long time, this may quickly lead to the serious consequences of the battery discharging completely and the concrete mixer truck can not be started.
3、 Do not refuel until the tank bottoms out
Some people are lazy, others seldom pay attention to the fuel tank scale, and they will drive a certain distance before refueling until the fuel tank warning light is on. But sometimes when you go to a gas station after the fuel warning light is on, there may be a situation that there is no gas station nearby, causing confusion. And often such a case, since the concrete mixer, the pump life may be greatly reduced.
