4. Setup Instructions
- Inspect Equipment: Before each use, inspect the spray gun, hose, and pump for any damage, wear, or loose connections. Ensure all components are clean and free of debris.
- Connect Hose: Securely attach the high-pressure airless hose to the spray gun's inlet connection. Ensure all fittings are tightened to prevent leaks.
- Install Spray Tip: Insert the appropriate spray tip (e.g., LTX 517 as seen in Figure 1) into the tip guard and attach the tip guard assembly to the spray gun. Ensure it is securely fastened.
- Prepare Material: Ensure the paint or coating material is properly mixed and strained according to the manufacturer's recommendations.
- Connect to Pump: Connect the other end of the high-pressure hose to your airless paint sprayer pump.
- Prime System: Follow your airless pump's instructions to prime the system, circulating the material until all air is purged from the hose and gun.
5. Operating the Spray Gun
- Engage Trigger Lock: Always ensure the trigger lock is engaged when not actively spraying or when moving the gun.
- Adjust Pressure: Set the airless sprayer pump pressure to the recommended level for your material and tip. The gun is rated for a maximum working pressure of 5000 PSI (345 bar).
- Test Spray: Before spraying your work surface, perform a test spray on a piece of scrap material to check the spray pattern and adjust pressure as needed.
- Spraying Technique: Maintain a consistent distance (typically 10-12 inches) from the surface and move the gun in smooth, even passes. Overlap each pass by approximately 50% for uniform coverage.
- Release Trigger: Release the trigger at the end of each pass to avoid excessive material buildup.
- Clean Clogs: If the spray tip clogs, engage the trigger lock, rotate the tip 180 degrees, disengage the lock, and spray briefly to clear the obstruction. Re-engage the lock and return the tip to the spraying position.
6. Maintenance and Cleaning
Proper maintenance ensures the longevity and performance of your Graco Silver Plus Airless Spray Gun.
- After Each Use:
- Flush the spray gun and hose thoroughly with an appropriate cleaning solvent (e.g., water for latex, mineral spirits for oil-based paints) until the solvent runs clear.
- Remove the spray tip and tip guard. Clean them separately using a brush and solvent.
- Wipe down the exterior of the gun to remove any paint residue.
- Regular Inspection: Periodically check the gun's components, including the trigger, needle, and seals, for wear or damage. Replace worn parts as necessary.
- Storage: Store the spray gun in a clean, dry place, protected from extreme temperatures.
