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、保證水箱里有足夠的水，有減水劑。若料太干，放不出料的時候，減水劑就是救命稻草了，要不然悶罐可就麻煩了。

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、確認自動混凝土攪拌機處于停工狀態。因為發動機啟動時萬一罐子處于高速旋轉狀態，瞬間的力會很大的，傷害減速機。

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，自動混凝土攪拌機是一種特殊材質的運用車輛，若是在平日運用的進程里沒有清洗潔凈，是很容易就出現了沾罐的狀況的，所以我們要做好自動混凝土攪拌機的清潔工作。

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.
