During the actual operation of the high pressure washer, always maintain hands and soles of the feet, not directly contact these cleaning nozzles, and always check all electrical connections, check all internal inside and check their hoses. Is there a crack or a leak? If the gun is not used, these devices must be placed in * * * locked state.

What should I pay attention to when using a high-pressure cleaning machine?

Before use, you should check the pump. If not, you should add oil before use. Before use in winter, check whether the machine is frozen. If there is ice, the ice will melt before turning it on; after the use, drain the water in the pump and put the machine in the heated room to prevent the machine from freezing.

1. When using the equipment, the power supply shall be equipped with leakage protection switch and grounded * * *, and must match the socket with good grounding wire; the input (input) voltage should ensure its stability, too low or too high voltage will cause damage to the equipment. In general, the voltage of single power should be between 220V-240V, and three power should be between 380V-400V.

2. Input (input) power line diameter should not be too thin, not too long. General cleaning equipment motor power is large, for the capacitor starting motor, starting current is large. Therefore, the selection of cable wire diameter section should not be less than 4 square, the length of the wire should not be longer than 25 meters. The wire shall be thick to 6 square meters; otherwise the electricity will cause heat, not start, and even burn out.

3. The high pressure pipe is strictly prohibited to be rolled over by heavy objects such as vehicles, so as to avoid the bursting of the high pressure rubber pipe.

4. During the use of the machine, it is strictly prohibited to send high pressure water to the position of the cooling fan, to prevent the leakage danger caused by the motor water.

5. ① In addition to paying attention to the power voltage problem but also consider the diesel * * * to choose good, and does not contain impurities, not allowed to mix water.②, diesel label should be selected according to the temperature change of the weather. The basic formula is as follows: the current ambient temperature is subtracted from 15. For example, when the current ambient temperature is zero, the selected diesel label is minus 15 and minus 25.③ Water quality should be clean, as far as possible without impurities, and the water filter screen should be cleaned regularly. Every time the machine is used, the water in the pump should be discharged, and put the machine in the heated room, in case the cold weather will freeze the machine.
