1. The Medium concrete mixer should be set in a flat position, and the front and rear wheel axles are cushioned with square wood to keep the tires overhead, so as not to move when starting.
2. The Medium concrete mixer should be implemented with secondary leakage protection. After the power is turned on before work, it must be carefully checked, and it can be used after being tested by an empty car. During the test run, it is necessary to check whether the speed of the mixing drum is appropriate. Generally, the speed of the empty car is slightly faster than that of the heavy car (after loading) by 2 to 3 turns. If there is a large difference, the ratio of the moving wheel to the driving wheel should be adjusted.
3. The rotation direction of the mixer should conform to the direction indicated by the arrow. If it is not true, the motor wiring should be corrected.
4. Check whether the transmission clutch and brake are flexible and reliable, whether the wire rope is damaged, whether the track pulley is good, whether there are obstacles around it, and the lubrication of various parts.
5. After starting, pay attention to the normal operation of each part of the concrete mixer. When stopping, often check whether the blades of the concrete mixer are bent, and whether the screws are falling or loose.
6. When the concrete is stirred or is expected to stop, the remaining material will be cleaned out. Use stones and water to pour into the shaker, turn it on, and wash out the mortar adhered to the bucket. There must be no accumulated water in the barrel to prevent the barrel and blade from rusting. At the same time, the ash accumulation on the outside of the mixer should be cleaned to keep the machine clean and intact.
7. After work and when the Medium concrete mixer is not in use, the gate should be turned off and the switch box should be locked to ensure safety.
