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.
