4. Setup

1. Unpacking: Carefully remove all components from the packaging. Check for any damage during transit.
2. Assembly:
   • Attach the high-pressure hose to the sprayer outlet and the spray gun. Ensure all connections are tight.
   • Connect the suction tube and return tube to the sprayer.
   • Insert the spray tip into the spray gun.
3. Prepare Paint: Ensure your paint is properly mixed and, if necessary, thinned according to the paint manufacturer's recommendations. Strain the paint to remove any lumps or debris that could clog the sprayer.
4. Priming the Sprayer:
   • Place the suction tube into the paint container and the return tube into a waste bucket.
   • Set the pressure control to the lowest setting.
   • Turn on the sprayer. Allow the pump to draw paint through the system until a steady stream flows from the return tube.
   • Once primed, turn off the sprayer and move the return tube into the paint container.
5. Test Spray: Before painting your project, perform a test spray on a piece of cardboard or scrap material to adjust pressure and ensure a consistent spray pattern.

5. Operating Instructions

1. Work Area Preparation: Mask off areas not to be painted and cover floors or furniture to protect them from overspray.
2. Adjust Pressure: Turn the pressure adjustment knob to the desired setting. Higher viscosity paints typically require higher pressure.
3. Spraying Technique:
   • Hold the spray gun perpendicular to the surface, maintaining a consistent distance (typically 25-30 cm or 10-12 inches).
   • Move the gun in smooth, even strokes, overlapping each pass by about 50%.
   • Release the trigger at the end of each stroke to avoid paint buildup.
   • For optimal results, apply multiple thin coats rather than one thick coat.
4. Automatic Stop Function: The sprayer features an automatic stop function that pauses the pump when the trigger is released, conserving energy and reducing wear.
5. Using the Extension Rod: For high ceilings or hard-to-reach areas, attach the 0.5-meter extension rod to the spray gun.

6. Maintenance

Proper cleaning and maintenance are crucial for the longevity and optimal performance of your airless paint sprayer.

1. Immediate Cleaning After Use:
   • Disconnect power.
   • Remove the suction tube from the paint and place it into a bucket of appropriate cleaning solution (water for latex, mineral spirits for oil-based paints).
   • Turn on the sprayer and flush the system until the cleaning solution runs clear from the spray gun.
   • Remove the spray tip and guard, clean them separately.
   • Clean the exterior of the sprayer and hose.
2. Pump Protector/Storage Fluid: After cleaning, run pump protector fluid through the system before storing to prevent corrosion and freezing.
3. Filter Cleaning: Regularly check and clean the fluid filter to ensure proper paint flow and prevent clogs.
4. Nozzle Maintenance: If the spray tip becomes clogged during operation, reverse the tip and spray briefly to clear the obstruction.
5. Storage: Store the sprayer in a clean, dry, and frost-free environment.
