Preparations Before Using the High-Pressure Cleaner

1.Check the integrity of the equipment

Before using the high-pressure cleaner, it is necessary to conduct a comprehensive inspection of the equipment first. Check whether the machine body has any damage, cracks or deformation, and ensure that all connection parts are firm and there are no signs of looseness. Pay special attention to whether the connections of the high-pressure water gun, high-pressure water hose, power cord (if it is an electric high-pressure cleaner) or fuel hose (if it is a fuel-powered high-pressure cleaner) are tight and whether there is any damage or leakage.

2. Connect the water source and power supply or add fuel

Depending on the type of high-pressure cleaner, make corresponding energy connections or supply preparations. For an electric high-pressure cleaner, insert its power cord plug into a power socket with good grounding that meets the power requirements of the equipment to ensure a stable power supply and no leakage risk. For a fuel-powered high-pressure cleaner, add the appropriate fuel grade into the designated fuel tank according to the requirements of the equipment manual, and be careful not to let the fuel overflow. Regardless of the type of high-pressure cleaner, connect the water inlet to a clean water source, such as a faucet or a water bucket (when using the self-priming function), and ensure that the water source supply is sufficient and free of impurities to avoid clogging the water inlet pipe or damaging the water pump.

3.Select the appropriate nozzle and adjust the pressure

High-pressure cleaners are usually equipped with various types of nozzles to adapt to different cleaning tasks. For example, a 0-degree nozzle can produce a concentrated high-pressure water flow, which is suitable for removing stubborn stains or dirt in narrow gaps; the water flow of a 15-degree nozzle is slightly more dispersed and can provide a relatively strong cleaning force on a larger area, and is often used for cleaning vehicle surfaces, floors, etc.; the water flow of a 25-degree or 40-degree nozzle is more dispersed and has a larger coverage area, which is suitable for cleaning relatively fragile or large-area surfaces, such as exterior walls, glass, etc. Before starting the cleaning, select the appropriate nozzle according to the material and dirt degree of the object to be cleaned and install it on the high-pressure water gun. At the same time, adjust the pressure of the high-pressure cleaner according to the cleaning needs. Most high-pressure cleaners are equipped with a pressure adjustment knob or switch. Generally, for relatively fragile surfaces, such as car paint surfaces, wooden materials, etc., the pressure should be adjusted to a lower level (usually between 500 - 1000 pounds per square inch); while for solid and heavily soiled surfaces, such as concrete pavements, metal equipment, etc., the pressure can be appropriately increased (it can be 1500 - 3000 pounds per square inch or higher). However, please note that excessive pressure may damage the surface of the object to be cleaned, so be extremely cautious when adjusting the pressure.
