    1. When operating the concrete mixer, pay attention that the pressure of the hydraulic system shall comply with the provisions in the operation manual and shall not be adjusted at will. The oil quality and quantity of hydraulic oil shall meet the original requirements.
    2. During operation, do not put your hand into the rotating mixing drum, and do not put your hand into the connection between the main discharge chute and the extended discharge chute, so as to avoid accidents.
    3. When operating the concrete mixer, pay attention to drain the residual ponding and sundries in the mixing drum before loading. Keep rotating during transportation to prevent concrete segregation. Before the concrete mixer truck arrives at the construction site and unloading, the mixing drum shall rotate at full speed at 14-18 rpm for 1-2 minutes, and then reverse unloading. Before reversing, the mixing drum shall be stopped stably.

After unloading at the construction site, immediately flush the inlet hopper, outlet hopper and discharge chute with the hose attached to the mixer truck to remove the sludge and concrete adhered to the vehicle body. On the way back to the mixing plant, 150-200l water shall be injected into the mixing drum to clean the concrete residue bonded to the drum wall and blades.
    6. When removing the accumulated dirt and residual concrete slag inside and outside the mixing drum, and when the mechanical maintenance personnel enter the drum for maintenance and welding repair, it is necessary to turn off the automobile engine first to stop the mixing drum completely. During the period when the mechanical maintenance personnel enter the drum for work, they must ensure that the mixing drum is well ventilated, the air is fresh, there is no combustible gas and harmful dust, and the oxygen supply is sufficient.
