1、 Excessive hot car

不管是冬季还是其它季节，有很多车主都习惯采取原地怠速热车的方式，热车一段时间再行驶，觉得自上料混凝土搅拌车，这时性能佳。但事实上，原地怠速热车不仅效果有限，还浪费汽油和时间。当引擎在没有负荷的状态下，温度的爬升是相当缓慢的，也就是说，引擎在怠速状态下需要很长的时间才能达到正常的工作温度。正确的做法应当是自上料混凝土搅拌车，原地热车30秒左右后，立即上路行驶。但由于此时引擎及驱动系统都尚未达到正常的工作温度，仍应将转速控制在约2000转/分钟之内，待水温达到正常后方可高转速运行。

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.

二、熄火后仍使用电器设备

2、 Use of electrical equipment after flameout

一旦自上料混凝土搅拌车，熄火，蓄电池就处于只放电不充电的工作状态。所以如果在长时间熄火后仍然一直在使用车内大功率用电器，比如开着车辆大灯、停车在路边长时间听音乐等等，这样可能很快导致蓄电池彻底放电、自上料混凝土搅拌车，无法启动的严重后果。

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.

三、油箱见底后才加油

3、 Fill the tank after it bottoms out

有人比较懒，有人是很少去注意油箱刻度，直到油箱警示灯亮起后还会再行驶一段距离再去加油。可是有时燃油警示灯亮起后再去找加油站时，有可能出现附近没有加油站的情况，弄得手忙脚乱。而且经常出现这样的情况的话，自上料混凝土搅拌车，的油泵寿命可能会大大降低。

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.
