4. Operating Instructions
Proper operation ensures efficient and consistent paint application.
4.1 SmartControl 3.0 System
The SmartControl 3.0 system continuously monitors the sprayer's performance and adjusts the motor speed to match your spraying needs. This ensures a consistent spray pattern and finish. The display provides real-time information on:
- Sprayer gallons used
- Operating hours
- Current pressure settings
- Diagnostic support messages
4.2 BlueLink Job and Sprayer Management System
Utilize the BlueLink system to track your sprayer's activity and manage job progress. This feature helps maximize uptime by providing insights into usage and maintenance schedules.
4.3 Spraying Technique
- Hold the spray gun perpendicular to the surface, maintaining a consistent distance (typically 10-12 inches).
- Begin moving your arm before pulling the trigger and release the trigger before stopping your arm movement.
- Overlap each pass by approximately 50% to ensure even coverage.
- Adjust pressure settings on the SmartControl 3.0 as needed for different materials and desired finishes.
5. Maintenance and Cleaning
Regular maintenance and thorough cleaning are essential for extending the life of your Graco Ultra Max II 495 PC Pro and ensuring optimal performance.
5.1 FastFlush High-Flow Cleaning System
The FastFlush system allows for quick and efficient cleaning. Follow these steps:
- Relieve pressure from the system.
- 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 valve to the "CLEAN" or "FLUSH" position (refer to specific model instructions for exact valve position).
- Turn on the sprayer and allow the cleaning solution to circulate until it runs clear from the prime hose and spray gun.
- Turn off the sprayer and relieve pressure.
- Remove and clean the spray tip and guard separately.
5.2 General Maintenance
- Inspect hoses and connections regularly for wear or damage. Replace as needed.
- Check the spray tip for wear. A worn tip will result in a poor spray pattern and increased material consumption.
- The MaxPower Brushless DC Motor is designed for maintenance-free performance, but ensure it remains free of debris.
- Store the sprayer in a clean, dry environment, protected from freezing temperatures.
6. Troubleshooting
This section provides solutions to common issues you may encounter during operation. For more complex problems, consult the full Graco service manual or contact customer support.
| Problem | Possible Cause | Solution |
|---|---|---|
| No spray or low pressure | Clogged tip, clogged filter, air in system, worn pump packings. | Clean tip/filters, re-prime unit, inspect/replace packings. |
| Pulsating spray | Air in system, loose suction tube, worn inlet valve. | Re-prime, tighten connections, inspect/replace inlet valve. |
| Poor spray pattern (tails) | Worn spray tip, incorrect pressure setting, material too thick. | Replace tip, adjust pressure, thin material if necessary (follow paint manufacturer guidelines). |
| Motor runs but no pressure builds | Inlet valve stuck open, prime valve in wrong position. | Clean/free inlet valve, ensure prime valve is in "SPRAY" position. |
