2, concrete mixer should implement secondary leakage protection, before going to work, after connecting the power supply, must be carefully checked, empty test run that qualified, before use. During the trial operation, check whether the speed of the mixing drum is appropriate. In general, the speed of an empty car is 2~3 revolutions faster than that of a car (after loading). If the difference is large, the ratio of the moving wheel to the driving wheel should be adjusted.
3. The rotating direction of the mixing drum should be consistent with the direction indicated by the arrow. If it is not correct, correct the motor wiring.
4. Check whether the transmission clutch and brake are flexible and reliable, whether the wire rope is damaged, whether the track pulley is in good condition, whether the surroundings are accessible and the lubrication of each part.

6. When the concrete mixing is finished or it is expected to stop 1, the remaining materials will be discharged. Pour stones and water into the bucket, start the machine, and rinse all the mortar stuck on the bucket before discharging. There must be no water in the bucket to avoid rust of the bucket and blades. At the same time, clean up the dust accumulated outside the mixing drum and keep the machinery clean and intact.
7, after work and stop when not in use, should switch power, and lock the switch box, to ensure safety.
