How to use high pressure washer?

1. Preparation before starting the High Pressure Washer Check whether the screws and nuts in each part of the washer are loose before starting the machine. 30# or 40# oil has been added to the pump eccentric axle box, and the oil level needs to be checked (just over the oil mirror is beneficial).

2, the water inlet pipe connection cover the water inlet hose on the pump body, and then cover the throat card, tighten the screw on the throat card to ensure that the connection is firm and no air leakage. Then according to the situation of the water source, the other end of the tap or into the water supply tank (the water inlet must be immersed in water), the inlet pipe requires the installation of a filter to avoid the inhalation of impurities damage to the high-pressure pump.

3. The outlet water pipe connection connects the connector end of the high-pressure hose with the quick-change connector on the outlet of the machine; The other end is connected to a threaded joint on the gun trigger valve. The connection method of the quick change joint: just push the knurled sleeve back, and then push the joint inside. Note: High-pressure water pipe can not be twisted, as far as possible to extend, straighten.

4, the power supply connection must first determine the power supply voltage and the label provisions are consistent, the high pressure cleaning machine used by the fixed power supply connection should be carried out by professionals, and should meet the relevant requirements. If an extension power cord is used, the plug and socket should be of waterproof construction. When connecting the socket, the switch of the cleaning machine must be set in the "off" position.

5, the replaceable nozzle spray gun can adjust the spray water by changing the nozzle, the short qiang head is the round hole bundle water flow, the long qiang rod is the fan water flow. Round hole stream beam - This nozzle produces a strong stream beam for use on particularly dirty surfaces. Such as agricultural machinery, construction machinery, etc. Fan-shaped water flow - the nozzle produces fan-shaped jet, the scattering Angle is large, the impact force on the object to be cleaned is small, can be used for large areas of dirt surface cleaning, such as cars, buses, trucks, towing machines and other various vehicles, ships; Vegetable and food processing plants, hotel kitchens; Bath, swimming pool; Barn and livestock fence, high-rise building exterior wall cleaning.

6, start the machine to check that the high pressure cleaning machine inlet pipe and outlet high pressure pipe has been connected reliably, the power socket is connected, you can switch on the power, pull the trigger of the spray gun, after the air in the machine is drained, you can have high pressure water ejection. When the air is discharged slowly for the first time, the high pressure pipe of the outlet water can be removed first, and when there is no gas at the outlet water connector, the high pressure pipe is connected at the quick connector, and then the machine is turned on again.

7, if the water tank to the pump water, should be started at the same time, from the inlet pipe to the pump water, half pull the trigger of the spray gun, in order to discharge the air in the pipeline, after the pump works normally, the inlet pipe can be placed in the water tank. At this time, the inlet of the water inlet pipe must be equipped with a filter screen to prevent foreign matter inhalation.

8. When cleaning with a bundle of strong jets, the distance between the nozzle and the cleaned surface should not be too close, so as to avoid damage to the cleaned object due to high pressure. When cleaning the vulnerable surface, it should be from far to near, and carefully observe its changes.
