High pressure airless paint sprayers use a high-pressure plunger pump to pressurize the paint to 3000 PSI (210 kg/cm). The paint is delivered to the spray gun through a high-pressure hose, and the pressure is released through the nozzle to form atomization that creates a dense coating on the surface of the wall. Since no compressed air is required to atomize the paint, it is called airless spraying. 1. Before using this high-pressure airless spray machine, please make sure to read carefully and strictly comply with the requirements of this instruction manual. 2. The high-pressure airless sprayer must be placed smoothly and securely during the operation. The operator must pay attention to personal safety in the process of operation, if necessary, with a good protective cover and work cap after the operation. 3. The workplace should be well ventilated. The motor power cord and high pressure tube should not be stacked on the items or be stepped on, pressed etc. The high pressure pipe should be unobstructed on the way to be dragged during the operation to avoid damage to the high pressure pipe. 4. The voltage and frequency of the power supply used must be consistent with the nameplate on the motor. 5. Check carefully to confirm that the fasteners of the high-pressure airless sprayer are fastened securely before connecting to the power supply, and check to confirm that the pipe joints are connected securely. 6. To improve the service life of this high-pressure airless sprayer, the paint used should be clean, free of impurities and not deteriorated, and should be filtered through a filter of 80 mesh or more. 7. Pressure adjustment should not be greater than 200bar. If the high-pressure tube is replaced, the tube selected must be uniformly equipped by the paint sprayer manufacturer. 8. At no time is not allowed to point the gun at others, when operating to prevent the splash of paint on the operator's body, especially eye injury. 9. Don’t allow use the high-pressure airless sprayer spray acid, corrosive substances, toxic chemicals (such as pesticides, pesticides, etc.). Do not use banana water, dimethyl dumb and other solvents for spraying operations.during the operation, the operator should not eat food, do not smoke. 10. After the completion of the spraying operation, to unload the flow, unload the pressure, and then turn off the motor, and then immediately clean the parts of the paint flow through the cleaning solution, wash the residue, it is strictly prohibited to clean with boiling water. 11. When moving the airless sprayer, generally cut off the power supply, motor and plug are not allowed to contact with water and paint, keep the machine clean and dry. 12. The tools used in any fastening, adjustment and maintenance of this airless sprayer should be suitable and the operation should be standardized to prevent damage to the machine or the person. 13. Do not allow arbitrary changes to the structure of this airless sprayer. Do not use spare parts that do not meet the requirements.

An airless paint sprayer is a great tool for painting projects, but it needs to be properly cleaned and maintained in order to keep it in good working condition. Cleaning an airless paint sprayer is not difficult, but it does require some special steps. Here are the steps you should take to properly clean your airless paint sprayer: 1. Start by disconnecting the power source from the airless paint sprayer and removing any remaining paint from the airless spray nozzle. This can be done with a brush or a cloth. 2. Once all of the paint has been removed, fill the reservoir with warm water and add a few drops of dish soap. This will help break down any remaining paint residue and make it easier to remove. 3. Turn on the power source and run the pump for several minutes to circulate the soapy water through the system. This will help loosen any remaining residue that may have built up in the lines or filters. 4. After running for several minutes, turn off the power source and allow the soapy water to sit in the reservoir for 10-15 minutes before draining it out completely. 5. Once all of the soapy water has been drained out, refill the reservoir with clean water and run it through again for several minutes to flush out any remaining residue or soap suds that may still be present in the system. 6. Finally, turn off the power source once again and allow all of the water to drain out completely before storing your airless paint sprayer away until you need it again! Following these steps will ensure that your airless paint sprayer is properly cleaned and ready for use when you need it next time!

1. Clean the airless paint sprayer after each use: It is essential to clean the sprayer after every use by flushing it with water or solvent. This prevents paint from drying inside the system and clogging the airless sprayer nozzle or filter. 2. Check the filter regularly: The filter of the airless paint sprayer needs regular inspection and cleaning, as it can quickly become clogged with paint debris. A clogged filter will result in a decreased spray pattern, uneven coatings, and even cause the paint sprayer to stop working. 3. Lubricate the airless sprayer piston pump frequently: The piston of the sprayer requires regular lubrication to prevent it from seizing up. Use a high-quality lubricant recommended by the paint sprayer manufacturer to ensure that it operates smoothly. 4. Store the paint sprayer machine correctly: When storing the airless paint sprayer, make sure that it is in a clean and dry environment. The hose and gun should be disconnected, and the pump should be covered to prevent dust and debris from collecting on it. 5. Inspect the paint sprayer hoses and connections: Regularly inspect the hoses and connections for any signs of wear or damage. Replace damaged hoses or connections immediately to prevent leaks, which can damage the airless paint sprayer and cause waste of paint. By following these maintenance tips, you will keep your airless paint sprayer operating at its best and ensure excellent results every time you use it.
