Precautions For The Use Of High Pressure Cleaners

1. Before starting the machine, check whether the connection between the screws and nuts of each part of the cold water high pressure washer is loose. 2. Check whether the pipe joints and high-pressure hoses of the cold water high-pressure cleaner are damaged. If they are found to be damaged, they should be replaced in time to avoid the danger of sudden bursting. 3. When the intermittent time is too long (more than 10 minutes), turn off the power supply of the cold water high pressure washer, open the spray gun valve of the cold water high pressure washer, and release the pressure completely. 4. When connecting the socket, the switch of the cold water pressure washer must be set to the 'off' position. If an extension power cord is used, the plug and socket must be waterproof. 5. Connect the water outlet pipe of the cold water high pressure washer, and connect the inserting joint end of the cold water high pressure cleaning machine hose to the quick joint of the water outlet of the machine, and the other end to the threaded joint on the trigger valve of the spray gun. 6. The working pressure of the cold water high pressure washer pump has been adjusted when it leaves the factory. Users should not increase the pressure at will to avoid the cold water high pressure washer being damaged or accidents due to changes in the working state. 7. When using a beam-shaped powerful jet for high-pressure cleaning, the distance between the nozzle of the cold-water high-pressure cleaner and the surface to be cleaned should not be too close, so as to avoid damage to the object to be cleaned due to excessive pressure. Note: Car tires/tire valves are only allowed to be cleaned at a distance of 30 cm. 8. Do not point the cold water pressure washer gun at anyone or any part of the body. Cold water pressure washer fluid leaks from the gun, or hose, broken fittings, and small objects can pierce the skin and cause injury. Do not put your hand on the front of the cold water pressure washer nozzle. 9. When carrying out the cold water high pressure cleaning operation, you should adopt the correct posture to hold the handle of the cold water high pressure washer spray gun with one hand, and hold the cold water high pressure washer nozzle with the other hand, and pay attention to the water spray when pulling the trigger. When the spray gun will generate a certain recoil force and rotational torque to the handle, pay attention when operating the cold water high pressure washer. 10. Connect the water inlet pipe of the cold water high pressure washer, put the water inlet hose of the cold water high pressure washer on the water inlet joint of the cold water high pressure washer of the pump body, then put on the throat clip, and tighten the screws on the throat clip to ensure that the connection is firm and not. Air leak. Then put the other end on the tap or put it into the water supply pool (the water inlet must be completely immersed in the water) according to the water source.
