During the actual operation of the high-pressure washer, always keep your hands and feet away from direct contact with these cleaning nozzles, and always check all electrical connections, check all internal liquids and check their hoses. Are there cracks or leaks? If the spray gun is not used, these devices must be placed in a safe locked state.
What should be paid attention to when using high pressure cleaning machine?

Before use, check whether there is oil in the pump, if not, add oil before use. Before using in winter, check whether the machine freezes. If there is ice, it is necessary to make the ice melt before starting the machine. After use, the water in the pump should be drained and the machine should be placed in the room with heating to prevent the machine from being damaged by cold weather.
1. When using the equipment, the power supply must be equipped with leakage protection switch and grounded safely, and the socket with good grounding wire must be used to match it; the input (input) voltage should ensure its stability. If the voltage is too low or too high, the equipment will be damaged. In general, the voltage of single power supply should be between 220 V and 240 V, and that of three items should be between 380 V and 400 V.
2. Input (input) power line diameter should not be too thin, let alone too long. The motor power of general cleaning equipment is large, and the starting current is large. Therefore, when selecting cables, the wire diameter section should not be less than 4 square meters, and the wire length should not be longer than 25 meters. If it is more than 25m, the wire should be thickened to 6 square meters; otherwise, the motor will cause heating, not starting, or even burn out.

3. It is strictly forbidden to roll the high-pressure pipe by heavy objects such as vehicles, so as to avoid the bursting of high-pressure rubber pipe.
4. During the operation of the machine, it is strictly forbidden to shoot the high-pressure water flow to the position of the cooling fan blade of the machine, so as to prevent the risk of electric leakage caused by water entering into the motor.
5. ① in addition to paying attention to the power supply voltage, it is also necessary to consider that the diesel oil used must be good and free of impurities, let alone water. ② Diesel oil label should be selected according to the weather and temperature changes. The basic formula is as follows: the current ambient temperature minus 15, for example: when the current ambient temperature is zero, the selected diesel label is negative 15, and when minus 10 ℃, it is negative 25 diesel. ③ The water quality of the water source should be clean and free of impurities as far as possible, and the inlet filter screen should be cleaned regularly. Every time the machine is used up, the water in the pump should be drained, and the machine should be placed in the room with heating, so as to prevent the machine from being damaged by cold weather.
