1、平口混凝土搅拌车装料前，应先排净拌筒内残存的积水和杂物，在运输过程中要不停的转动，以防混凝土离析，混凝土搅拌运输车到达工地和卸料之前。应先使拌筒全速以14—18转/分转动1—2分钟，然后再进行反转卸料，反转之前，应使搅拌筒停稳不转。
1. Before loading the concrete mixer truck, the residual water and sundries in the mixing drum shall be drained, and it shall rotate continuously during the transportation process to prevent the concrete from segregation. Before the concrete mixer truck arrives at the construction site and unloading. The mixing drum should be rotated at full speed for 1-2 minutes at 14-18 rpm, and then the reverse discharging should be carried out. Before the reverse discharging, the mixing drum should be stopped.
2、液压系统压力应符合使用说明书中的规定。不得随意调整，液压油的油质和油量应符合原定要求。
2. The pressure of the hydraulic system shall meet the requirements of the operation manual. The quality and quantity of hydraulic oil should meet the original requirements.
3、环境温度高于+25摄氏度，从装料、运输、到卸料延续时间不得超过60分钟。环境温度低于+25摄氏度，上述时间不得超过90分钟。
3. When the ambient temperature is higher than + 25 ℃, the duration of loading, transportation and unloading shall not exceed 60 minutes. When the ambient temperature is lower than + 25 ℃, the above time shall not exceed 90 minutes.
4、冬期施工时，应切实做到：开机前检查是否结冰，下班时认真排除拌筒内及供水系统内残存积水。关闭水泵开关，将控制手柄置于“停止”位置。
4. During winter construction, it is necessary to check whether there is ice before startup, and carefully remove the residual water in the mixing drum and water supply system after work. Turn off the water pump switch and put the control handle in the "stop" position.
5、在施工现场卸料完毕后。应立即用平口混凝土搅拌车随带的软管冲洗进料斗、出料斗、卸料溜槽等处，清除粘附在车身各处的污泥及混凝土。在返回搅拌站的途中，应向搅拌筒内注150---200L水以清洗筒壁及叶片粘结的混凝土残渣。
5. After unloading at the construction site. The feeding hopper, discharging hopper and discharging chute shall be washed immediately with the hose attached to the flat concrete mixer truck to remove the sludge and concrete adhered to the body. On the way back to the mixing plant, 150-200l water should be injected into the mixing drum to clean the concrete residue bonded on the wall and blades of the drum.
6、每天工作结束后，混凝土搅拌车司机应负责向搅拌筒内注入清水并高速（14—18转/分）旋转5—10分钟，然后将水排去。以保障筒内清洁，用高压水清洗搅拌筒各个部分时，应注意避开仪表及操纵杆等部位，压力水喷嘴与车身油漆表面间的距离不得小于40厘米。
6. At the end of each day's work, the driver of the concrete mixer truck shall be responsible for injecting fresh water into the mixing drum, rotating at a high speed (14-18 RPM) for 5-10 minutes, and then discharging the water. When cleaning all parts of the mixing drum with high-pressure water, pay attention to avoid the instrument and control lever, and the distance between the pressure water nozzle and the body paint surface shall not be less than 40 cm.
7、清除混凝土搅拌车搅拌筒内外积污及残存的混凝土渣块时，以及在机修人员进入筒内进行检修和焊补作业时，需先关闭汽车发动机，使搅拌筒完全停止转动，在机修人员进入筒内工作期间，要保障拌筒内通风良好，空气新鲜，无可然气体及有害灰尘，氧气供应充足（不得使用纯氧），在筒内使用电动工具操作时，操作人员要有良好的绝缘保护。
7. When removing the dirt and residual concrete slag inside and outside the mixing drum of the concrete mixer, and when the maintenance personnel enter the drum for repair and welding, the engine of the truck should be turned off to stop the rotation of the mixing drum completely. During the period when the maintenance personnel enter the drum for work, it is necessary to ensure that the mixing drum is well ventilated, the air is fresh, and there is no natural gas and harmful dust, The oxygen supply is sufficient (pure oxygen is not allowed). When using electric tools in the cylinder, the operator should have good insulation protection.
8、工作时，不得将手伸入旋转的搅拌筒内。严禁将手伸入主卸料溜槽和加长卸料溜槽的连接部位，以免发生事故。
8. When working, do not put your hand into the rotating mixing drum. It is strictly forbidden to extend your hand into the connection part of the main discharge chute and the extended discharge chute to avoid accidents.
