4. Setup
Proper setup is crucial for optimal performance and safety. Follow these steps to prepare your sprayer for use:
- Assemble the Cart: Attach the wheels and telescopic handle to the upright cart. Ensure all connections are secure. The 5-gallon pail bracket should be properly positioned.
- Connect the Hose: Securely attach the 1/4-inch by 35-foot airless spray hose to the sprayer unit and the spray gun. Hand-tighten connections, then use a wrench for a final snug fit, but do not overtighten.
- Install the Spray Tip: Insert the 515/211 VersaTip reversible airless spray tip into the spray gun. Ensure it is seated correctly and the guard is in place.
- Prepare Paint: Stir your paint thoroughly. If necessary, thin the paint according to the paint manufacturer's recommendations. Place the paint pail onto the cart's bracket.
- Prime the Sprayer: Follow the priming instructions in the detailed user manual to remove air from the system and draw paint into the pump. This typically involves setting the prime/spray valve to prime and running the unit until paint flows smoothly.
5. Operating Instructions
Once the sprayer is set up and primed, you can begin painting. Always maintain a consistent distance and speed for an even finish.
- Adjust Pressure: Set the pressure control to the desired level. The Wagner 9155 can operate up to 3000 PSI. Start with a lower pressure and gradually increase until you achieve a consistent spray pattern without tails.
- Test Spray: Before painting your main surface, test the spray pattern on a piece of scrap material. Adjust pressure or tip as needed.
- Spraying Technique:
- Hold the spray gun perpendicular to the surface, maintaining a distance of approximately 10-12 inches.
- Move your arm, not just your wrist, to ensure an even coating.
- Overlap each pass by about 50% to avoid streaks.
- Release the trigger at the end of each pass to prevent paint buildup.
- Changing Tips: The sprayer supports up to a .017 spray tip for different materials and spray patterns. Always relieve pressure from the system before changing tips.
6. Maintenance
Regular cleaning and maintenance extend the life of your sprayer and ensure consistent performance. Clean the unit immediately after each use.
- Relieve Pressure: Always turn off the sprayer and relieve all pressure from the system before cleaning or performing any maintenance.
- Flush the System:
- Remove the paint pail and place the intake tube into a pail of appropriate cleaning solution (water for latex, mineral spirits for oil-based paints).
- Set the prime/spray valve to prime and run the sprayer until the cleaning solution runs clear.
- Switch to spray mode and spray the cleaning solution through the gun into a waste container until clear.
- Clean the Spray Tip: The 515/211 VersaTip is reversible. If a clog occurs during use, reverse the tip and spray briefly to clear it. After use, remove the tip and clean it thoroughly with a brush and cleaning solution.
- Clean Filters: Remove and clean all filters (in-line filter, gun filter) with the appropriate cleaning solution.
- Storage: Store the sprayer in a clean, dry place. For long-term storage, consider using a pump protector fluid to prevent corrosion and freezing.
