1) When the fire truck uses the foam proportioning mixer to spray, the water pump cannot inhale the pressure water of the fire hydrant;
2) When the power take-off is cut in or out, attention should be paid to whether the clutch is completely disengaged, and the speed of the engine is very low, so as to smoothly engage or disengage, and avoid accidents such as broken teeth or broken forks;
3) The idling time of the fire pump without water shall not exceed 3 minutes, and it is strictly forbidden to run at high speed in the absence of water;
4) During use, when closing all the water outlet valves, the speed of the fire pump must be reduced first, so as not to cause the fire pump to run for a long time beyond the rated working pressure;
5) After the water diversion is completed, the water diversion button must be reset;
6) The power take-off will generate a certain amount of heat when it is working, so in summer or when the working time exceeds 10 minutes, the cooling water plug valve must be opened to cool the gear oil of the power take-off, otherwise it will fail. After the work is completed, it must be Drain the remaining water;
7) In the process of extinguishing fire, the fire pump may use corrosive water source, so it must be rinsed with clean water after use and the remaining water must be drained;
8) In winter, when the ambient temperature is below 0 degrees Celsius, a related water release valve (fire pump, fire monitor, and water pipe valve, etc.) should be opened in time after use to avoid freezing of related components.
In short, in order to ensure that the fire truck can always maintain a good state of combat readiness, drivers and operators must be required to operate correctly and carefully check all parts of the fire truck every day, so as to detect hidden dangers in time, deal with faults in time, and be in a state of combat readiness at all times. , quickly deal with fire.
