Safety Information

Always prioritize safety when operating spray painting equipment. Failure to follow safety guidelines can result in serious injury or property damage.

• Ventilation: Use in a well-ventilated area to prevent the accumulation of hazardous fumes. If adequate ventilation is not available, use appropriate respiratory protection.
• Personal Protective Equipment (PPE): Always wear appropriate PPE, including safety glasses or goggles, gloves, and a respirator suitable for paint fumes.
• Flammable Materials: Many paints and solvents are flammable. Keep away from open flames, sparks, and other ignition sources. Do not smoke while operating the spray gun.
• Pressure Safety: Never exceed the maximum recommended air pressure for the spray gun. Always release air pressure from the system before performing maintenance or cleaning.
• Chemical Exposure: This product can expose you to chemicals including lead, which is known to the State of California to cause cancer and birth defects or other reproductive harm. For more information go to www.P65Warnings.ca.gov.
• Electrical Safety: Ensure all electrical connections for air compressors or other equipment are properly grounded and in good condition.
• Children and Pets: Keep children and pets away from the work area and equipment.

Setup

1. Unpack Components: Carefully remove all items from the molded case and inspect for any damage.
2. Select Fluid Tip: Choose the appropriate fluid tip (1.0mm, 1.3mm, or 1.8mm) based on the viscosity of the material you intend to spray. Ensure the corresponding needle and air cap are installed.
3. Attach Fluid Cup: Securely attach the gravity-feed fluid cup to the top of the spray gun.
4. Connect Air Supply: Connect the air adjusting valve to the spray gun's air inlet, then connect your air hose from the compressor to the air adjusting valve. Ensure all connections are tight to prevent air leaks.
5. Initial Cleaning: Before first use, clean the spray gun thoroughly with an appropriate cleaning solvent to remove any manufacturing residues.

Operating Instructions

1. Prepare Material: Mix and thin your paint or coating material according to the manufacturer's instructions. Strain the material to remove any particles that could clog the gun.
2. Fill Fluid Cup: Pour the prepared material into the gravity-feed fluid cup. Do not overfill.
3. Set Air Pressure: With the air adjusting valve, set the air pressure at the gun to the recommended PSI for your material. For HVLP guns, this is typically between 10-30 PSI (Maximum Pressure: 30 PSI).
4. Adjust Spray Pattern:
   • Fan Control Knob: Adjust this knob to change the width of the spray pattern, from a narrow round pattern to a wide fan.
   • Fluid Control Knob: Controls the amount of material flowing through the gun. Turn clockwise to decrease flow, counter-clockwise to increase.
5. Test Spray: Always perform a test spray on a piece of scrap material to verify the spray pattern and material atomization before applying to your actual workpiece. Adjust settings as needed.
6. Spraying Technique:
   • Maintain a consistent distance (typically 6-8 inches) from the surface.
   • Move the gun at a steady, even speed, overlapping each pass by about 50%.
   • Trigger the gun fully at the beginning of each pass and release at the end to avoid excessive material buildup.

Maintenance

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

1. Immediate Cleaning: Clean the spray gun immediately after each use. Do not allow paint to dry inside the gun.
2. Empty Fluid Cup: Empty any remaining material from the fluid cup.
3. Flush Gun: Pour a small amount of appropriate cleaning solvent into the cup and spray it through the gun until clear solvent emerges.
4. Disassemble and Clean:
   • Remove the air cap, fluid tip, and needle.
   • Use the provided cleaning brushes and solvent to thoroughly clean all internal and external parts. Pay special attention to the air cap holes and fluid passages.
   • Do not use metal objects to clean the fluid tip or air cap holes, as this can damage them.
5. Lubrication: Lightly lubricate the needle packing and air valve packing with a non-silicone lubricant designed for spray guns.
6. Reassembly and Storage: Reassemble the gun carefully. Store the clean and dry spray gun in its molded case to protect it from dust and damage.
