There are many places that are easy to be ignored in the maintenance of automatic feeding mixer. Let's take a look at which aspects.

一、二者之间的自锁系数变小、自锁性能下降。在搅拌车高速行驶时，螺栓螺母很容易松动乃脱落，从而引发行车事故。 不要用水冲洗车身，因为夏天气温高，很多司机选择用水冲洗车身，在拿干净的抹布擦拭，但其实车身内部是不能用水来冲洗的。因为驾驶室内地板胶垫的下面可不是“一马平川”，结构上的需要使驾驶室地板胶垫下面的凹槽、通孔非常多。

1、 The self-locking coefficient between the two becomes smaller and the self-locking performance decreases. When the mixer is running at high speed, the bolts and nuts are easy to loose or even fall off, which will cause traffic accidents. Don't wash the car body with water because of the high temperature in summer. Many drivers choose to wash the car body with water and wipe it with a clean cloth. However, the interior of the car body can not be washed with water. Because the lower part of the floor rubber pad in the cab is not "flat", there are many grooves and through holes under the rubber pad of the cab floor due to the structural needs.

用水冲洗后，要么沉积在凹槽内不易干燥，要么从通孔处流到变速箱等部件上产生锈蚀。尤其是密封性能较好的轿车更不能用水直接冲洗车身内部。

After washing with water, it will either deposit in the groove, which is not easy to dry, or flow from the through-hole to the gearbox and other components to produce rust. Especially the car with good sealing performance can not directly wash the interior of the car body with water.
 

正确的方法是用湿抹布擦拭，但要避免积水。 不同企业的冷却液不要混合使用 不同企业的冷却液其化学性能可能相差悬殊，比如对黑色金属有效的防腐剂，却常常对铝制品有腐蚀作用;而适用于铝台金的防腐剂则对铁合金有害。由于不同企业的冷却液所用的防腐剂不同，所以不能混合使用。

The correct way is to wipe with a wet cloth, but to avoid water. Do not mix different brands of coolants. The chemical properties of different brands of coolants may vary greatly. For example, the effective preservatives for ferrous metals often corrode aluminum products, while the preservatives suitable for aluminum alloy are harmful to ferroalloys. Because different brands of coolant use different preservatives, they cannot be mixed.

二、启动时不要踩油门：启动搅拌车发动机前踩几脚油门，是许多搅拌车驾驶员的习惯，尤其是在冬季冷车启动时。装有电控喷油装置的搅拌车发动机与普通化油器式发动机不同，它的喷油控制装置能根据搅拌车发动机的温度、工况自动调整供油量，使搅拌车发动机顺利启动，即在冷车启动时，喷油控制装置能自动增加供油量。所以，搅拌车发动机启动时，没有必要踩油门，更不要在启动前连续急踩，否则反而使搅拌车发动机启动不良。

2、 Don't step on the accelerator when starting: it is the habit of many mixer drivers to step on the accelerator before starting the engine, especially when the vehicle is cold in winter. The mixer engine equipped with electronic fuel injection device is different from the common carburetor engine. Its fuel injection control device can automatically adjust the fuel supply according to the temperature and working conditions of the mixer engine, so that the mixer engine can start smoothly, that is, when the vehicle is cold, the fuel injection control device can automatically increase the fuel supply. Therefore, when the mixer engine starts, there is no need to step on the accelerator, let alone continuously step on the accelerator before starting, otherwise it will make the mixer engine start poorly.

三、不要给自动上料搅拌车的轮胎螺栓螺母涂油 在车轮维修中，少数司机为了防止搅拌车的车轮上螺栓螺母生锈，安装时别出心裁地将螺栓螺母都涂上润滑油，殊不知这种做法不仅错误，而且给搅拌车行车带来一定的隐患。螺栓和螺母拧紧后，相互间具有自锁的特性。而涂上润滑油后，

3、 Don't oil the tire bolts and nuts of the automatic loading mixer. In the wheel maintenance, a few drivers, in order to prevent the bolts and nuts on the wheels of the mixer from rusting, apply lubricating oil to the bolts and nuts when installing. They do not know that this practice is not only wrong, but also brings certain hidden dangers to the driving safety of the mixer. After the bolt and nut are tightened, they are self-locking. After applying lubricating oil,
