    Prepare special supply hoses and spray guns for polyurethane materials. If you must use spray equipment that sprays other materials to spray polyurethane material, thoroughly clean the equipment before spraying. Otherwise you will spend most of your spraying work cleaning the spray head.
    When spraying is completed, clean the spray gun with a cleaning solvent. The solvent must go through the entire spraying process of the spraying equipment, including the spray gun. Turn the spray head over and over again to ensure that all polyurethane material remains. Stop material supply, reduce gun pressure, and remove gun head and gun head bracket. Remove the spray gun head from the stand and place it in a solvent tank. Remove the spray gun and place it in a solvent tank.
    Place the fluid tube in the cleaning solvent bucket you use to clean the gun equipment. Closing the air pressure or opening the fluid valve allows the cleaning solvent to flow slowly and permanently through the entire fluid tube.
    Continue to use the pump inside the spray gun to clean the solvent for 5-10 minutes. Pour part of the cleaning solvent into another bucket, and insert the suction hose of the spraying equipment into the bucket of this cleaning solvent, but the hose remains in the original bucket. Continue to use the pump inside the spray gun to clean the solvent until the remaining solvent becomes clean and free of impurities. Clean the filter system and carefully adjust the valve at the bottom of the filter system to drain the polyurethane residue into a small bucket. Because the opening and closing of this valve may cause the liquid in the filtration system to spray or spray, the pressure in the system should be turned off before the valve is opened, and then the pressure is slowly adjusted to the valve to slowly and stably discharge the liquid. When the effluent becomes pure, close the valve.
    Now that the solvent in the spray system is clean, put the fluid tube in the same barrel as the suction hose, and let the entire spray system continue the spray cycle for 10-15 minutes or longer as needed.
    If you plan to continue spraying with the spray equipment the next day, you also need to keep the cleaning solvent in the spray system and just turn off the air supply to the spray system. If you do not plan to use the spray equipment for a while, fill the spray equipment with filling fluid. This helps prevent the spray system from freezing in long-term storage.
