Use safety
1. The mixer should be set up in a flat position, with square wood used to cushion the front and rear axles, so that the tires are elevated to avoid walking during operation.
2. The mixer should be equipped with secondary leakage protection. After the power is turned on before work, it must be carefully inspected and deemed qualified after the empty car test run before use. During the trial operation, it is necessary to check whether the mixing drum speed is appropriate. Generally, the empty car speed is slightly faster than the car (after loading) by 2-3 revolutions. If there is a significant difference, the ratio of the driving wheel to the transmission wheel should be adjusted.
3. The rotation direction of the mixing drum should comply with the direction indicated by the arrow. If not, the motor wiring should be corrected.
4. Check whether the transmission clutch and brake are flexible and reliable, whether the steel wire rope is damaged, whether the track pulley is in good condition, whether there are obstacles around, and the lubrication of various parts.
5. After starting up, always pay attention to the normal operation of all components of the mixer. When shutting down, frequently check if the mixer blades are bent and if the screws are loose or loose.
6. When the concrete has been mixed or is expected to stop for more than 1 hour, in addition to discharging the remaining materials, stones and clean water should be poured into the shaking drum, and the machine should be turned on and turned to rinse the mortar adhered to the drum before unloading it completely. There should be no accumulated water inside the material barrel to prevent rusting of the barrel and blades. At the same time, the accumulated ash outside the mixing drum should also be cleaned to keep the machinery clean and intact.
7. After work and when not in use during shutdown, the power should be turned off and the switch box locked to ensure safety.
