4. Setup
- Unpack Components: Carefully remove all items from the packaging.
- Connect High-Pressure Hose: Attach one end of the high-pressure hose to the fluid outlet on the sprayer unit and the other end to the spray gun. Ensure all connections are tight using an adjustable wrench.
- Install Spray Tip and Guard: Securely attach the spray tip guard to the spray gun, then insert the appropriate spray tip.
- Position Suction and Return Tubes: Place the suction tube with its filter into the paint container. Position the return tube into a waste pail or back into the paint container for priming.
- Prime the Sprayer:
- Ensure the prime/spray valve is in the "Prime" position.
- Turn on the sprayer. The pump will draw paint through the suction tube and expel air and paint through the return tube.
- Once a steady stream of paint flows from the return tube, the system is primed. Turn off the sprayer.
5. Operating Instructions
- Prepare Work Area: Mask off areas not to be painted and ensure adequate ventilation.
- Adjust Pressure: Turn the pressure control knob to the desired setting. Start with a lower setting and increase gradually until a consistent spray pattern is achieved.
- Begin Spraying:
- Move the prime/spray valve to the "Spray" position.
- Hold the spray gun approximately 10-12 inches (25-30 cm) from the surface.
- Maintain a consistent distance and speed for an even coat. Overlap each pass by about 50%.
- Release the trigger at the end of each pass to avoid paint buildup.

- Remove the suction tube from the paint and place it into a container of appropriate cleaning solution (water for latex, mineral spirits for oil-based paints).
- Place the return tube into a waste container.
- Set the prime/spray valve to "Prime" and turn on the sprayer until clear cleaning solution flows from the return tube.
- Move the valve to "Spray" and spray the cleaning solution into a waste container until clear.
- Clean Spray Gun and Tip: Disassemble the spray tip and guard. Clean all components thoroughly with the appropriate cleaning solution and a brush.
- Auto Lube Attendant: The sprayer features an auto lube attendant. Periodically check the lubricant level and refill as needed according to manufacturer instructions to ensure proper pump lubrication.
- Storage: Store the sprayer in a clean, dry, and frost-free environment.
