5.2 Priming the Sprayer
Before spraying, the unit must be primed to remove air from the system and ensure a consistent paint flow.
- Place the suction tube into the paint.
- Turn the prime/spray valve to the "Prime" position.
- Turn on the sprayer. Allow paint to circulate through the return hose until a steady stream of paint flows without air bubbles.
- Once primed, turn the prime/spray valve to the "Spray" position.

6. Operating Instructions
6.1 Adjusting Pressure
The AEROPRO AP8628 features an adjustable pressure control knob, allowing you to select the appropriate pressure for your paint and surface. Pressure ranges from 0-500 PSI for rolling, 500-1000 PSI for prime/clean, 1000-1800 PSI for low-pressure spray, and 1800-3300 PSI for high-pressure spray.

6.2 Spraying Techniques
For optimal results, maintain a consistent distance (approximately 10-12 inches) from the surface and move the spray gun in smooth, even strokes. Overlap each pass by about 50% to ensure uniform coverage. The 360° swivel joint airless spray gun provides better flexibility during operation.

7. Maintenance

Thorough cleaning after each use is critical to prevent paint from drying and clogging the system, ensuring the longevity and performance of your sprayer.
- Turn off the sprayer and relieve pressure.
- Remove the suction tube from the paint and place it into a bucket of cleaning solution (water for latex, appropriate solvent for oil-based paints).
- Turn the prime/spray valve to "Prime" and run the sprayer until clear cleaning solution flows from the return hose.
- Turn the valve to "Spray" and spray the cleaning solution through the gun until it runs clear.
- Disassemble the spray gun tip and guard, clean them thoroughly with the provided cleaning brush.
- Clean the exterior of the sprayer and hoses.

7.2 Filter Replacement
The 50-mesh filters should be regularly inspected and replaced to prevent clogs and ensure consistent spray quality. Refer to the image above for visual guidance on filter replacement.
8. Troubleshooting
8.1 Sprayer Not Priming
If the sprayer motor is humming but not drawing paint, or if there's no sound, follow these steps:
- Check Sprayer Motor: If the motor is humming, it's likely working. If there's no sound, the motor might require professional service.
- Clear Blockages: Ensure the power switch is OFF. Remove the feed tube and turn the sprayer upside down. Use a long, thin tool to reach the bottom of the pump body and press down. Keep pressing until you feel a rebound, indicating the check valve is free. If there's a blockage, you won't feel the spring-back; press firmly until it bounces back.
- Inspect Lower Pump Body: If the above step doesn't resolve the issue, use a wrench to remove the lower pump body assembly and clear any blockages in this part using the same method. Reinstall securely.
- Pro Tip: Clogs often occur during the second use if dried paint accumulates. Always clean your sprayer thoroughly after each job!

8.2 Clogged Tip
If the spray pattern is inconsistent or stops, the tip may be clogged. The reversible tip design allows for quick clearing:
- Engage the spray gun trigger lock.
- Rotate the reversible tip 180 degrees.
- Disengage the trigger lock and spray for a moment to clear the blockage.
- Re-engage the trigger lock and rotate the tip back to the spraying position.
