Operating Instructions

The Graco Ultra Cordless Airless Sprayer is designed to deliver a perfect airless finish at any speed without thinning most materials.

1. Prime the Sprayer: With the paint cup attached and filled, set the sprayer to the "Prime" position (if applicable, or follow specific priming instructions in the full manual). Trigger the sprayer into a waste container until paint flows smoothly and all air is expelled.
2. Adjust Pressure: The sprayer features adjustable pressure from 500 to 2000 PSI. Adjust the pressure dial to suit your material and desired spray pattern. Start with a lower pressure and gradually increase until you achieve an optimal spray.
3. Spraying Technique:
   • Maintain a consistent distance (typically 10-12 inches) from the surface.
   • Move the sprayer in smooth, even strokes, overlapping each pass by approximately 50%.
   • Release the trigger at the end of each stroke to prevent paint buildup.
4. Continuous Operation: The Triax Triple Piston Pump ensures consistent performance. Monitor the FlexLiner bag and refill as needed.

Maintenance

Proper cleaning and maintenance are essential for the longevity and optimal performance of your sprayer.

1. Immediate Cleaning: Clean the sprayer immediately after each use. Remove the FlexLiner bag and dispose of any remaining paint properly.
2. Flush with Cleaning Solution: Fill a new FlexLiner bag with an appropriate cleaning solution (water for latex, mineral spirits for oil-based paints). Attach it to the sprayer and spray into a waste container until the solution runs clear. Repeat this process multiple times.
3. Thorough Cleaning: Disassemble the spray tip, guard, and any other removable parts. Clean them thoroughly with a brush and cleaning solution. Pay close attention to the filter screen, ensuring it is free of clogs.
4. Pump Cleaning: To ensure no water remains in the pump after cleaning, tap the trigger a few times to pump out as much water as possible before storing or attaching a new paint cup.
5. ProConnect System: The Triax Triple Piston Pump is fully repairable. The ProConnect system allows for quick and easy pump replacement if needed, extending the life of your sprayer.
6. Storage: Store the cleaned sprayer in its storage bag in a dry, temperature-controlled environment.

Troubleshooting

Refer to this section for common issues and their solutions.

• Sputtering or No Spray:
  • Clogged Filter Screen: Check the filter screen located in the sprayer. If clogged with paint film, clean it thoroughly. Wiping it with a finger at each refill can help prevent clogs.
  • Air in FlexLiner: Ensure the FlexLiner bag is properly seated and the paint cup is securely attached to prevent air from entering the system. Air in the FlexLiner can cause the motor to shut off.
  • Low Battery: Ensure the battery is fully charged.
• Large Droplets or Inconsistent Spray Pattern:
  • Clogged Blue Tip Shield: Paint buildup on the blue tip shield can block the spray pattern, causing globs. Clean the tip shield regularly.
  • Worn Spray Tip: A worn spray tip can lead to an inconsistent pattern. Replace the tip if necessary.
  • Incorrect Pressure: Adjust the pressure setting to match the material and desired finish.
• Motor Shuts Off:
  • Air Leak: Check for proper sealing at the connection between the cup cover and cup support. An air leak can cause the motor to shut off.
  • Overheating: Allow the sprayer to cool down if it has been in continuous heavy use.
• Water in Paint After Cleaning:
  • Some water may remain in the sprayer after cleaning. Before attaching a new paint cup, tap the trigger a few times to pump out any residual water. This prevents thinning of the initial paint.
