1.禁止用大锤敲打的方法积存在混凝土搅拌机筒内的混凝土，只能用凿子；
1. It is forbidden to use a sledgehammer to knock away the concrete accumulated in the concrete mixer barrel, and only a chisel can be used to remove it;
2.混凝土搅拌机在停工后用水和石子倒入搅拌筒内10~15分钟进行清洗，再将水和石子清出。注意清洗时，要切除电源；
2. After the concrete mixer is shut down, water and stones shall be poured into the mixing drum for 10-15 minutes for cleaning, and then water and stones shall be removed. Pay attention to cut off the power supply when cleaning;
3.清洗要定期进行，定期进行保养规程所规定项目的维护、保养作业，如清洗、润滑、加油等。
3. Cleaning shall be carried out on a regular basis, and the maintenance and repair work of the items specified in the maintenance procedures shall be carried out on a regular basis, such as cleaning, lubrication, oil filling, etc.
混凝土搅拌车发动机中起润滑作用的机油，涉及搅拌车发动机的使用寿命。有些司机不明白这个道理，随便更换任意企业的机油，就很容易使混凝土搅拌车机发动机出现拉缸、烧瓦等等机械事故。
The lubricating oil in the concrete mixer engine relates to the service life of the mixer engine. Some drivers don't understand the reason. If they change the oil of any brand, they will easily cause mechanical accidents such as cylinder pulling, tile burning and so on.
机油的更换一般在一万左右，也有的要求七千或五千更换机油，这些可以根据混凝土搅拌车行驶条件和行驶路况而定。但换机油时千万不要添加那些不的添加剂、剂等。
The change of engine oil is generally around 10000 km, and there are also some requirements for 7000 km or 5000 km oil change, which can be determined according to the driving conditions and road conditions of the concrete mixer. But when changing the engine oil, do not add any additives, agents, etc.
注意更换机油时要换混凝土搅拌车机机油滤芯，如果为了省钱，不换机油滤芯，那机油的性能和效果会大打折扣。
Pay attention to changing the oil filter element of the concrete mixer when changing the oil. If the oil filter element is not changed in order to save money, the performance and effect of the oil will be greatly reduced.
