4. Setup

Proper setup is crucial for optimal performance and safety.

1. Connect Hose: Attach your high-pressure spray hose to the inlet connection of the spray gun. Ensure the connection is tight and secure to prevent leaks under pressure. The inlet connection size is 3.5 inches.
2. Verify System Compatibility: Ensure your pump and hose system can deliver the required flow rate (5-25 GPM) and pressure (100-850 PSI) for your application.
3. Inspect Nozzle: Check that the nozzle is securely attached and free from obstructions.
4. Prepare Solution: If using chemicals, prepare your spray solution according to the chemical manufacturer's instructions.

5. Operating Instructions

Follow these steps for effective operation of the spray gun:

1. Start Pump: Turn on your spray pump and allow the system to build pressure.
2. Initiate Spray: Aim the spray gun at the target area. Squeeze the trigger handle to begin spraying.
3. Adjust Spray Pattern: Rotate the nozzle at the end of the gun to adjust the spray pattern. Turning it one way will produce a fine cone spray, while turning it the other way will create a concentrated jet stream. Experiment to find the optimal pattern for your task.
4. Control Flow: The trigger allows for precise control over the flow of the spray.
5. Cease Spraying: Release the trigger to stop the spray.
6. Shut Down: After use, turn off the pump and relieve all pressure from the system before disconnecting the spray gun.

6. Maintenance

Regular maintenance ensures the longevity and reliable performance of your spray gun.

• Rinse After Use: After each use, especially when spraying chemicals, thoroughly rinse the spray gun with clean water to prevent chemical buildup and corrosion.
• Inspect for Wear: Periodically inspect the spray gun for any signs of wear, damage, or leaks, particularly around connections and the trigger mechanism.
• Check Nozzle: Ensure the nozzle is clear of debris. If clogged, carefully clean it using a soft brush or compressed air. Do not use metal objects that could damage the orifice.
• Lubrication: If the trigger mechanism becomes stiff, apply a small amount of silicone-based lubricant to moving parts.
• Storage: Store the spray gun in a clean, dry place, protected from extreme temperatures and direct sunlight.
