1. The concrete mixer shall be set at a flat position, and the front and rear axles shall be padded with square wood to make the tires empty, so as to avoid moving when starting.

2、混凝土搅拌机应实施二级漏电维护，上班前电源接通后，有必要仔细检查，经空车试转认为合格，方可运用。试作业时应检验拌筒转速是否合适，一般状况下，空车速度比重车（装料后）稍快2~3转，如相差较多，应调整动轮与传动轮的份额。

2. The concrete mixer shall be subject to secondary leakage maintenance. It is necessary to check carefully after the power supply is connected before work. It can be used only after it is considered qualified by the empty vehicle test run. During trial operation, check whether the rotating speed of the mixing drum is appropriate. Generally, the empty speed is slightly faster than that of the truck (after loading). If there is a large difference, adjust the share of the driving wheel and the driving wheel.

3、拌筒的旋转方向应契合箭头指示方向，如不符实，应更正电机接线。

3. The rotation direction of the mixing drum shall conform to the direction indicated by the arrow. If it is inconsistent, the motor wiring shall be corrected.

4、检查传动离合器和制动器是否灵活可靠，钢丝绳有无损坏，轨道滑轮是否杰出，周围有无妨碍及各部位的光滑状况等。

4. Check whether the transmission clutch and brake are flexible and reliable, whether the steel wire rope is damaged, whether the track pulley is outstanding, whether there are obstacles around and the smoothness of each part, etc.

5、开机后，常常注意混凝土搅拌机各部件的作业是否正常。停机时，常常检查混凝土搅拌机叶片是否打弯，螺丝有否打落或松动。

5. After startup, always pay attention to whether the operation of all parts of the concrete mixer is normal. During shutdown, often check whether the blades of the concrete mixer are bent and whether the screws are dropped or loose.

6、当混凝土搅拌完毕或预计停歇1h以上，除将余料出净外，使用石子和清水倒入抖筒内，开机转动，把粘在料筒上的砂浆冲洗干净后悉数卸出。料筒内不得有积水，避免料筒和叶片生锈。同时还应整理搅拌筒外积灰，使机械保持清洁完好。

6. When the concrete mixing is completed or it is expected to stop for more than 1h, in addition to discharging the remaining materials, pour stones and clean water into the shaking drum, start the machine for rotation, and discharge all the mortar adhered to the drum after washing. There shall be no ponding in the barrel to avoid rust of the barrel and blades. At the same time, the ash accumulated outside the mixing drum shall be sorted out to keep the machinery clean and intact.

7、下班后及停机不用时，应拉闸断电，并锁好开关箱，以确保。

7. After work and when not in use, switch off and lock the switch box to ensure safety.

在对混凝土搅拌机进行清洗时应注意以下事项：

When cleaning the concrete mixer, pay attention to the following matters:

榜首、定时进行保养规程所规则项目的维护、保养作业，如清洗、光滑、加油等

At the top of the list, regularly carry out the maintenance and maintenance of the items specified in the maintenance procedures, such as cleaning, smoothing, refueling, etc

第二、混凝土搅拌机开动前要先检查各控制器是否杰出，罢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。操作人员如须进入搅拌筒内清洗时，除切断电源和卸下熔断器外，并须锁好开关箱。

Second, before starting the concrete mixer, check whether each controller is excellent. After the strike, pour water and stones into the mixing drum for 10 ~ 15 minutes for cleaning, and then remove the water and stones. If the operator needs to enter the mixing drum for cleaning, he shall not only cut off the power supply and remove the fuse, but also lock the switch box.

第三、制止用大锤击打的方法铲除积存在混凝土搅拌机筒内的混凝土，只能用凿子铲除。

Third, it is prohibited to remove the concrete accumulated in the concrete mixer barrel by hammering with a big hammer, and only a chisel can be used to remove it.

第四、在严寒季节，作业完毕后使用水清洗搅拌机滚筒并将水泵、水箱、水管内积水放净，避免水泵、水箱、水管等冻坏。

Fourth, in the severe cold season, clean the mixer drum with water after operation, and drain the accumulated water in the water pump, water tank and water pipe to avoid freezing damage of the water pump, water tank and water pipe.
