1。  Before starting the equipment, first check whether some rotating and mixing drums are scratched. If there are scratches, they should be adjusted in time

2。滚筒混凝土搅拌机的变速箱在使用前应先用机油写明，卸压蜗轮和滑动轴承也应先用机油写明。

2。 The gearbox of drum concrete mixer shall be written with oil before use, and the pressure relief worm gear and sliding bearing shall also be written with oil.

3。在混合桶中安排杂物，锁定桶的极限设备，然后启动机器。起动后，如果工作方向不符合要求，应及时切断电源，并更换导体的两相线从头发。

3。 Arrange sundries in the mixing bucket, lock the limit equipment of the bucket, and then start the machine. After starting, if the working direction does not meet the requirements, cut off the power supply in time and replace the two-phase wire of the conductor from the hair.

4。卸货时，停止机器，然后松开约束手柄，800吨稳定土拌合站然后旋转手轮。蜗轮将料筒移动到出料位置并间歇滚动，然后启动机器使主轴工作，然后再出料，直到出料干净为止。主轴间歇工作，旋转手轮重设搅拌桶。

4。 When unloading, first stop the machine, then release the restraint handle, 800 ton stabilized soil mixing plant, and then rotate the hand wheel. The worm gear moves the material barrel to the discharge position and rolls intermittently, then starts the machine to make the main shaft work, and then discharges the material until the discharge is clean. When the main shaft works intermittently, rotate the hand wheel to reset the mixing drum.

5。混凝土搅拌机的电源接线必须准确，并且必须有可靠的零保护（或保护接地）和漏电保护开关。各部分的接线和绝缘必须符合规定的要求

5。 The concrete mixer must be provided with accurate power supply or neutral grounding protection, and the concrete mixer must be provided with accurate protection. The wiring and insulation of each part must meet the specified requirements

6。操作员必须经过培训并通过考试。

6。 Operators must be trained and pass the exam.

7。操作员有必要每天根据清洁，拧紧，润滑，调节和防腐的交叉工作方法对搅拌机进行仔细的保护和保养

7。 It is necessary for the operator to carefully protect and maintain the mixer according to the cross working methods of cleaning, tightening, lubrication, adjustment and anti-corrosion every day

8。仔细检查每个组件是否有异常迹象。行驶前，检查离合器，制动器和各种防护设备是否有效，可靠，钢丝绳是否损坏，履带和滑轮是否突出，机身是否稳定以及周围是否有障碍物在2-3分钟的测试工作后，感光鼓平稳滚动，不跳动，不脱落。

8。 Carefully check each component for signs of abnormality. Before driving, check whether the clutch, brake and various protective equipment are effective and reliable, whether the steel wire rope is damaged, whether the crawler and pulley are prominent, whether the body is stable and whether there are obstacles around. After 2-3 minutes of test work, the photosensitive drum rolls smoothly without jumping or falling off.
