2. Safety Information

WARNING: Failure to follow these safety instructions may result in serious injury or property damage.

• Always wear appropriate safety gear, including eye protection, respiratory protection, and gloves, when using this spray gun.
• Ensure adequate ventilation in the work area to prevent inhalation of fumes.
• Avoid contact with chemicals. Refer to the material safety data sheet (MSDS) for the specific coating material being used.
• Keep the spray gun away from heat sources, open flames, or sparks. Many coating materials are flammable.
• Use caution when operating the gun to prevent potential injuries from pressurized air or accidental discharge.
• Never point the spray gun at yourself or others.
• Disconnect the air supply before cleaning, performing maintenance, or changing parts.
• Keep children and unauthorized personnel away from the work area.

4. Product Features

The Astro EUROHE107 spray gun is designed for high efficiency and high transfer rates, offering reliable performance for various coating applications.

• High Efficiency/High Transfer: Reduces spray time and requires less overlap compared to traditional HVLP systems.
• Integrated Regulator: Allows for precise air pressure control directly on the gun.
• Durable and Lightweight Construction: Ensures comfortable handling and longevity.
• Optimal Performance: Engineered for consistent and smooth application of coatings.

5. Setup

1. Attach Plastic Cup: Securely screw the plastic gravity-feed cup onto the spray gun body. Ensure a tight seal to prevent leaks.
2. Connect Air Supply: Attach a suitable air hose (not included) to the air inlet at the bottom of the spray gun handle. Ensure the connection is secure and leak-free.
3. Adjust Air Pressure: Connect the air hose to an air compressor. Using the integrated regulator on the gun, set the operating pressure to approximately 29 psi (2.0-2.5 bar dynamic). Adjust as needed based on the coating material and desired finish.
4. Fill Cup: Pour the prepared coating material into the plastic cup. Do not overfill.
5. Test Spray: Before applying to your workpiece, perform a test spray on a scrap surface to verify spray pattern and material atomization. Adjust fluid and fan controls as necessary.

6. Operating Instructions

Proper technique is crucial for achieving optimal results with your spray gun.

• Distance: Maintain a consistent distance of 6 to 8 inches (15-20 cm) from the surface being sprayed.
• Movement: Move the gun parallel to the surface at a steady speed. Avoid arcing motions, which can lead to uneven coating.
• Overlap: Overlap each pass by approximately 50% to ensure uniform coverage. The maximum pattern at 6" to 8" distance is 11” – 13” (280-330mm).
• Trigger Control: Depress the trigger fully for consistent material flow. Release the trigger at the end of each pass.
• Air Consumption: The gun operates with an average air consumption of 10.5 – 12.5 cfm. Ensure your air compressor can meet this demand.
• Adjustments:
  • Fluid Control Knob: Located at the rear of the gun, this adjusts the amount of material sprayed.
  • Fan Control Knob: Typically located on the side, this adjusts the width of the spray pattern.
  • Air Inlet Knob (Regulator): Adjusts the air pressure entering the gun.

7. Maintenance

Regular cleaning and maintenance are essential for the longevity and performance of your spray gun.

1. Immediate Cleaning: After each use, immediately empty any remaining material from the cup.
2. Flush Gun: Pour appropriate cleaning solvent (compatible with your coating material) into the cup and spray it through the gun until it runs clear.
3. Disassemble and Clean:
   • Remove the air cap, fluid nozzle, and fluid needle.
   • Clean all components thoroughly with solvent and a brush. Pay close attention to small orifices.
   • Do not use metal objects to clean the nozzle or air cap, as this can damage them.
4. Lubrication: Apply a small amount of spray gun lubricant to the fluid needle packing and air valve packing periodically.
5. Reassembly: Reassemble the gun, ensuring all parts are correctly seated and tightened. Do not overtighten.
6. Storage: Store the clean and dry spray gun in a protective case or hang it in a clean, dry environment.
