- Install the Suction Tube: Insert the suction tube into the paint inlet on the sprayer unit. Ensure the filter end is submerged in the paint container during operation.
- Attach the Spray Gun and Nozzle: Connect the spray gun to the high-pressure hose. Select the appropriate nozzle for your paint and project, then install it onto the spray gun. If using the extension rod, attach it between the spray gun and the nozzle.

Operating Instructions
- Prime the Sprayer:
- Place the suction tube into a bucket of water (for water-based paints) or appropriate cleaning solution (for oil-based paints).
- Turn the prime/spray valve to the "Prime" position.
- Turn on the sprayer. Allow the water/solution to circulate until it flows smoothly from the return tube into the bucket, indicating air has been purged.
- Turn off the sprayer.
- Load Paint: Place the suction tube into your paint container.
- Set Pressure: Turn the prime/spray valve to the "Spray" position. Adjust the pressure knob to the desired setting. Start with a lower pressure and gradually increase until you achieve an even spray pattern. The sprayer offers up to 3800 PSI for efficient coverage.
- Test Spray: Before spraying your project, test the spray pattern on a piece of cardboard or scrap material. Adjust pressure and nozzle as needed.
- Spraying Technique:
- Hold the spray gun perpendicular to the surface, maintaining a consistent distance (typically 10-12 inches).
- Move your arm, not just your wrist, to ensure an even coat. Overlap each pass by about 50%.
- Release the trigger at the end of each pass to prevent paint buildup.
- For high or distant areas, utilize the 20-inch extension rod for improved reach.
- Finish Painting: Once your project is complete, turn off the sprayer and proceed to the cleaning section.

Maintenance
Proper maintenance is crucial for the longevity and performance of your airless paint sprayer.
- Cleaning After Each 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 the prime/spray valve to "Prime" and run the cleaning solution through the system until it runs clear.
- Turn the valve to "Spray" and spray the cleaning solution through the gun until it runs clear.
- Disassemble the spray gun, nozzle, and filters. Clean all components thoroughly with the cleaning brush and solution.
- Rinse all parts with clean water and allow them to dry completely.
- Lubrication: Apply a few drops of pump protector or light oil (from the empty lube bottle) to the pump's piston after each cleaning or before storage to prevent corrosion and maintain smooth operation.
- Storage: Store the sprayer in a clean, dry, and frost-free environment. Ensure all components are clean and dry before storage.
- Filter Replacement: Regularly inspect and replace filters (in the gun and suction tube) as needed to prevent clogs and maintain spray quality.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No spray or weak spray | Clogged nozzle, clogged filter, insufficient paint, air in system, low pressure setting. | Clean or replace nozzle/filter. Ensure sufficient paint. Prime the sprayer to remove air. Increase pressure setting. |
| Uneven spray pattern | Incorrect pressure, worn nozzle, improper spraying technique, paint too thick. | Adjust pressure. Replace nozzle. Review spraying technique. Ensure paint is suitable for thinning-free operation or consider a different nozzle. |
| Sprayer not priming | Air leaks in suction system, clogged inlet filter, prime/spray valve in wrong position. | Check all connections for tightness. Clean inlet filter. Ensure valve is in "Prime" position. |
| Motor runs but no pressure | Worn pump packing, inlet valve stuck open, air in system. | Contact customer support for pump packing replacement. Clean inlet valve. Prime the system. |
