Maintenance Information

To maintain peak performance and extend the life of your SuperFinish 21 Pro HEA, it’s crucial to clean the unit thoroughly after every use. Begin by removing the suction hose from the paint source and placing it into a container filled with the appropriate cleaning fluid—water for water-based paints, or solvent for oil-based materials. Activate the sprayer and hold the trigger open to flush the entire system until only clean liquid flows through the hose and gun. Make sure to direct the waste into a suitable disposal container.

Next, remove the spray tip and tip guard from the gun. Soak them in cleaning solution and gently scrub off any paint residue using the provided cleaning brush. Run more clean fluid through the gun itself to ensure all internal passages are clear. After the gun is cleaned, rinse the suction set, return line, and inlet filter thoroughly. Check for any clogs or buildup in the inlet and outlet valves and clean them if necessary.

Wipe down the external surfaces of the sprayer using a damp cloth, taking care to avoid excessive moisture near the control panel and electrical components. Once all parts are cleaned and rinsed, circulate a final flush of clean solution through the system to remove any last traces of material or solvent. Allow all components to air dry completely before storing.

If the sprayer will be out of use for more than a day, consider running a protective storage fluid—such as Wagner’s Pump Protector—through the unit to preserve internal seals and prevent corrosion. Proper daily cleaning reduces wear, ensures a consistent spray pattern, and minimises the risk of downtime on site.
