Always observe basic safety precautions when using this product to reduce the risk of personal injury and damage to the equipment. Read all instructions before operation.
General Safety Warnings:
- Wear Personal Protective Equipment (PPE): Always wear safety goggles, a respirator, and protective gloves when operating the spray gun. Ensure adequate ventilation in the work area.
- Flammable Materials: Do not spray flammable materials near open flames, pilot lights, or other ignition sources. Ensure the work area is free of sparks and heat.

3. Setup
Proper setup is crucial for safe and effective operation.
3.1. Preparing the Work Area
- Ensure the work area is well-ventilated and free from dust and debris.
- Cover surrounding areas and objects to protect them from overspray.
- Have all necessary materials, including paint, thinner, and cleaning supplies, readily available.
3.2. Connecting to Air Supply
- Attach an air hose (not included) to the air inlet fitting on the spray gun. Ensure the connection is tight.
- Connect the other end of the air hose to an air compressor equipped with a pressure regulator and moisture trap.
- Set the air compressor pressure regulator to the recommended operating pressure for your paint material (typically between 30-60 PSI, refer to paint manufacturer guidelines).
3.3. Preparing Paint Material
- Thoroughly mix the paint material according to the manufacturer's instructions.
- Strain the paint through a fine mesh filter to remove any impurities that could clog the spray gun.
- Pour the prepared paint into the 32 oz. aluminum cup. Do not overfill.
- Securely attach the cup to the spray gun body.
4. Operating Instructions
Follow these steps for effective and consistent spraying.
4.1. Adjusting the Spray Gun
- Fluid Control Knob: Adjusts the amount of paint flow. Turn clockwise for less paint, counter-clockwise for more.
- Fan Control Knob: Adjusts the spray pattern from a round spot to a wide fan. Turn clockwise for a narrower pattern, counter-clockwise for a wider pattern.
- Air Pressure: Adjust the air compressor regulator to achieve the desired atomization and spray pattern. Test on a scrap piece of material.
4.2. Spraying Technique
- Hold the spray gun perpendicular to the surface, approximately 6-10 inches away.
- Begin moving the gun before pulling the trigger and release the trigger before stopping the movement. This prevents paint buildup at the start and end of strokes.
- Overlap each pass by about 50% to ensure even coverage.
- Maintain a consistent speed and distance from the surface.
- Apply multiple thin coats rather than one thick coat to avoid runs and sags. Allow adequate drying time between coats as recommended by the paint manufacturer.
5. Maintenance
Regular cleaning and maintenance will prolong the life of your spray gun and ensure optimal performance.
5.1. Cleaning After Each Use
- Disconnect the air supply from the spray gun.
- Empty any remaining paint from the cup.
- Pour a small amount of appropriate cleaning solvent (e.g., paint thinner, lacquer thinner, water for water-based paints) into the cup.
- Reattach the cup, connect the air supply, and spray the solvent through the gun into a waste container until it sprays clear.
- Disconnect the air supply again.
- Disassemble the air cap, fluid nozzle, and needle. Clean these components thoroughly with a brush and solvent.
- Clean the inside of the paint cup and the gun body.
- Reassemble all parts, ensuring they are tightened correctly. Do not overtighten.
5.2. Storage
- Store the clean and dry spray gun in a cool, dry place, away from direct sunlight and extreme temperatures.
- Keep the gun out of reach of children.
6. Troubleshooting
Refer to this section for common issues and their solutions.
| Problem | Possible Cause | Solution |
|---|---|---|
| Poor spray pattern / Uneven coverage | Incorrect air pressure, paint too thick, clogged nozzle/air cap, damaged nozzle/air cap. | Adjust air pressure, thin paint, clean nozzle/air cap, replace damaged parts. |
| No paint flow | Clogged fluid nozzle, paint cup empty, fluid needle stuck, air vent in cup lid blocked. | Clean nozzle, refill cup, free fluid needle, clear air vent. |
| Paint leaks from nozzle | Loose fluid nozzle, worn fluid needle packing, damaged fluid needle. | Tighten nozzle, replace packing, replace fluid needle. |
| Excessive overspray | Too much air pressure, gun too far from surface, paint too thin. | Reduce air pressure, move gun closer, thicken paint. |
