With the steady progress of the construction of new urbanization and the continuous transformation and reconstruction of old urban areas, automatic concrete mixers shuttle among them. In order to ensure that the automatic concrete mixer does not fail in operation, it is necessary to check the machine before driving. 1. Check carefully and find and eliminate faults in time. Never let the car break down on the road, otherwise it will be troublesome for the tank to be stuffy. Generally, the tank of concrete can not be stopped for more than 2 hours. Check the engine oil, antifreeze, lubricating oil, etc. before ignition. If it is found to be insufficient, add it again. After the car starts, let the jar rotate at a low speed, check the tire pressure around the car, check whether there is a leaking tire, and then remove the stones in the tire seam with a screwdriver to check whether there are iron nails or the like stuck in the tire! Then check the light, especially the waist light, to ensure that it shines on the edge of the tire. The construction site will often pile up reinforcement and other things, and the sidewall is weak. Wipe the rear-view mirrors and window glass on both sides with a rag. The road conditions on the construction site are complex and the light is bad. The line of sight must be guaranteed first.

2、保证水箱里有足够的水，有减水剂。若料太干，放不出料的时候，减水剂就是救命稻草了，要不然闷罐可就麻烦了。

2. Ensure that there is enough water and water reducing agent in the water tank. If the material is too dry to discharge, the water reducing agent is a life-saving straw, otherwise it will be troublesome to stuffy the tank.

3、确认自动混凝土搅拌机处于停工状态。因为发动机启动时万一罐子处于高速旋转状态，瞬间的力会很大的，伤害减速机。

3. Confirm that the automatic concrete mixer is in shutdown state. Because when the engine is started, if the can is in the state of high-speed rotation, the instantaneous force will be great and damage the reducer.

另外，自动混凝土搅拌机是一种特殊材质的运用车辆，若是在平日运用的进程里没有清洗洁净，是很容易就出现了沾罐的状况的，所以我们要做好自动混凝土搅拌机的清洁工作。

In addition, the automatic concrete mixer is an application vehicle with special materials. If it is not cleaned in the process of daily use, it is easy to get stuck in the tank. Therefore, we should do a good job in the cleaning of the automatic concrete mixer.
