Setup

1. Unpacking: Carefully remove all components from the packaging. Inspect for any damage.
2. Assembly:
   • Attach the plastic cup to the spray gun body. Ensure it is securely tightened to prevent leaks.
   • Verify that the fluid tip, nozzle, and needle are correctly installed and tightened using the provided wrench.
3. Air Supply Connection:
   • Connect a clean, dry air hose to the air inlet of the spray gun.
   • Ensure your air compressor can provide the recommended average air consumption of 9-10 cfm at 29 psi.
   • It is recommended to use an air filter/regulator to ensure clean air and precise pressure control.
4. Material Preparation:
   • Prepare your painting material according to the manufacturer's instructions, including thinning if necessary.
   • Strain the material to remove any particles that could clog the spray gun.
   • Pour the prepared material into the plastic cup. Do not overfill.

Operating Instructions

1. Adjust Air Pressure: Set the air pressure at the gun's inlet to 29 psi using a regulator.
2. Adjust Fluid Control: Turn the fluid control knob (usually at the back of the gun) to adjust the amount of material flowing through the gun. Start with it fully closed and open gradually.
3. Adjust Fan Pattern: Turn the fan pattern control knob (usually on the side of the gun) to adjust the width and shape of the spray pattern. A wider pattern is suitable for larger surfaces, while a narrower pattern is for smaller areas or edges.
4. Test Spray: Before applying to your workpiece, perform a test spray on a scrap piece of material to check the pattern, atomization, and fluid flow. Adjust as needed.
5. Spraying Technique:
   • Hold the gun perpendicular to the surface, maintaining a consistent distance (typically 4-7 inches).
   • Move the gun at a steady speed, overlapping each pass by about 50%.
   • Trigger the gun fully at the beginning of each pass and release at the end to avoid heavy spots.
   • Maintain consistent wrist movement, avoiding arcing motions.
6. Cleaning During Use: If you pause spraying for an extended period, or if the gun starts to clog, spray a small amount of solvent through it to keep the passages clear.

Maintenance

Proper cleaning and maintenance are crucial for the longevity and performance of your spray gun.

1. Immediate Cleaning: After each use, immediately disconnect the air supply and empty any remaining material from the cup.
2. Flush with Solvent: Pour appropriate cleaning solvent into the cup and spray it through the gun until it runs clear.
3. Disassembly: Disassemble the air cap, fluid nozzle, and fluid needle.
4. Detailed Cleaning:
   • Clean all disassembled parts thoroughly with solvent and a cleaning brush. Pay special attention to the air passages and fluid tip.
   • Do not use metal objects to clean the nozzle or air cap holes, as this can damage them.
   • Clean the inside of the cup.
5. Lubrication: Apply a small amount of spray gun lubricant to the fluid needle packing and air valve packing.
6. Reassembly: Reassemble the gun, ensuring all parts are correctly seated and tightened.
7. Storage: Store the clean, dry spray gun in a safe place, protected from dust and damage.
