Operation is to pay attention to several key points
1. Before the operation of the concrete mixer truck, it is necessary to check to confirm that the steering, braking, lighting and signal systems are sensitive and useful, the drum and chute of the mixer truck are free of cracks and serious damage, the wear of the mixing blades is within the normal range, and the U-shaped bolts between the chassis and the subframe are well connected.

5. When reversing the concrete mixer truck for unloading, obey the command, pay attention to the surrounding personnel, and stop immediately in case of abnormalities.
6. It is strictly prohibited to clean the concrete mixer truck under the high-voltage line.
6. Routine maintenance
Since the concrete will solidify into hard blocks in a short time and have a certain corrosivity to steel and paint, cleaning the concrete adhered to the concrete storage tank and the inlet and outlet after each use of the concrete storage tank is a serious work for daily maintenance. These include:
a. Wash the inlet with water before loading each time to keep the inlet moist during loading;
b. Fill the cleaning water tank with water while loading;
c. Wash the inlet after loading and clean the residual concrete near the inlet;
d. After unloading at the construction site, wash the discharge tank, and then add 30-40 l of cleaning water to the concrete storage tank; Keep the concrete storage tank rotating forward and slowly when the vehicle returns;
e. Remember to discharge the sewage in the concrete storage tank before the next loading;
f. Clean the concrete storage tank and around the inlet and outlet at the end of each day to ensure that there is no cement and concrete caking.
