(1) When the ultra-high pressure washer is in working condition, the hose must not be twisted, and try to avoid bending. If you need to bend, make sure that the bending radius should not be too small, generally not less than 15 times the outer diameter of the pipe, otherwise the outer steel wire of the reinforcement layer will be stretched, the inner steel wire will be compressed, and the compressive strength of the entire ultra-high pressure hose will be reduced, which will ultimately affect the performance of the hose. service life.

(2) When the ultra-high pressure washer is in working state, the ultra-high pressure hose cannot be crushed by heavy objects, the sharp device is damaged, and does not bend, and the outer layer is protected from excessive wear; the suspension high-pressure hose should be fixed in a short distance.

(3) During the specific cleaning operation, try to avoid frequent opening and closing of the high-pressure spray gun to reduce the impact of pressure pulses on the hose and prolong the service life of the hose.

(4) When installing and removing the ultra-high pressure hose connection, it cannot be forcibly removed and tightened. The threads of the connecting thread should be protected. At the same time, lubricating oil should be applied to the outer surface of the thread during installation, and a protective sleeve should be used to protect the connecting thread after disassembly.

(5) When the ultra-high pressure hose is not used for a long time, the internal water should be drained, and the hose bending plate should be rolled up to the specified size. Particular attention should be paid to bends near ultra-high pressure hose fittings. The joint should be coated with anti-rust oil to avoid contact with high temperature, high pressure and strong corrosive medium.

(6) In order to prevent accidents when the joint falls off or is damaged, the ultra-high pressure hose should be provided with a steel wire braided protective sleeve at the connection, and the two ends of the connection should be connected.
