When operating a high-pressure cleaning machine, it is necessary to follow the usage rules stated in the manual in order to use it correctly, prevent malfunctions, and fully utilize its function. Under normal circumstances, the following points should be noted:



1. When operating a high-pressure cleaning machine, protective goggles should be worn, matching work clothes and shoes with protective effects should be worn. Prevent harm to oneself during operation.



2. It is important to choose the correct high-pressure nozzle in order to effectively utilize the cleaning machine. For example, a low-pressure nozzle can allow the cleaning machine to suck in cleaning agents, while a high-pressure nozzle can spray high-pressure water jets at different angles. Each high-pressure nozzle has a different fan-shaped spray angle, ranging from 0 degrees to 40 degrees. Choosing the appropriate high-pressure nozzle will achieve better cleaning results.



3. Before officially using the high-pressure cleaning machine, its power should be tested. A better approach is to start the cleaning machine one to two meters away from the cleaning area, use a large fan-shaped spray angle range, and adjust the spraying distance and angle of the cleaning machine accordingly depending on the specific situation. Move the high-pressure spray gun rod back and forth several times and check whether the surface being cleaned is clean. If you need to strengthen cleaning, move the high-pressure spray gun rod closer to the surface of the object being cleaned, which will achieve a better cleaning effect and be less likely to damage the object you are cleaning.



4. If detergent needs to be added, one should carefully read the label or instructions on the detergent to determine if it may cause potential harm to the object or person being cleaned. Be careful not to use bleach, and use approved detergents or cleaning solutions that can be added to the cleaning machine to ensure safe use. When using detergent, the sequence should be to spray from the bottom of the object being cleaned gradually to the top of the object. Before rinsing, stop for a short period of time, which is 5 to 10 minutes, to allow the detergent to settle on the object and begin to spread. The purpose of this operation is to give the chemical the appropriate time to take effect and decompose all the dirt. The residence time should be appropriate and not too long. If it is too long, the cleaning agent may be blown dry by the wind on the surface, and the effect will not be very good.



5. When it comes to the rinsing stage, the sequence should start from the top of the object and gradually rinse downwards to the bottom of the object until the entire surface is free of detergent and stripe marks. Only then can it be considered clean.



6. Caution should be exercised when using the high-pressure spray gun of a high-pressure cleaning machine to spray around windows, ventilation openings, eaves, and walls. Excessive water pressure may knock down loose or unsecured window glass or shatter it. It is necessary to adjust the pressure and water flow to an appropriate level.



In short, the operation and use of high-pressure cleaning equipment require training and thorough reading of the user manual, following the rules to truly master how to use the high-pressure cleaning machine.
