2.2 Nozzle Set Installation
The spray gun comes with 0.8mm and 1.0mm nozzle sets. To install or change a nozzle set:
- Ensure the spray gun is disconnected from the air supply.
- Unscrew the existing air cap and nozzle from the gun body.
- Carefully insert the desired needle into the gun body.
- Thread the new nozzle onto the gun body, ensuring it is snug but not overtightened.
- Attach the air cap over the nozzle.

3. Operating Instructions
3.1 Preparing the Paint
Ensure your paint is properly thinned according to the manufacturer's recommendations for spray application. The HVLP design works best with appropriate paint viscosity.
3.2 Connecting to Air Supply
Connect the spray gun to a pneumatic air compressor. Adjust the air pressure according to your paint type and desired spray pattern. Typically, HVLP guns operate at lower pressures (e.g., 10-30 PSI at the cap).
3.3 Filling the Gravity Cup
The A602 uses a gravity feed system. Pour the prepared paint into the cup attached to the top of the spray gun.
3.4 Spraying Technique
- Hold the gun perpendicular to the surface, maintaining a consistent distance (usually 6-8 inches).
- Move the gun in smooth, even passes, overlapping each pass by about 50%.
- Release the trigger at the end of each pass to avoid paint buildup.
- Practice on scrap material to achieve the desired finish before applying to your project.
4. Maintenance and Cleaning
Proper cleaning and maintenance are crucial for the longevity and performance of your spray gun.
4.1 Immediate Cleaning After Use
- Empty any remaining paint from the gravity cup.
- Pour a small amount of appropriate cleaning solvent (e.g., paint thinner for oil-based paints, water for water-based paints) into the cup.
- Spray the solvent through the gun until it runs clear.
- Disconnect the air supply.
4.2 Detailed Cleaning
- Disassemble the air cap, nozzle, and needle (refer to Figure 3).
- Clean these components thoroughly with a brush and cleaning solvent. The needle is made of durable stainless steel, the nozzle is stainless steel, and the air cap is plated brass.
- Pay special attention to the small holes in the air cap and nozzle to ensure they are free of clogs.
- Clean the paint passage within the gun body.
- Lubricate moving parts (e.g., needle packing) with a few drops of spray gun lubricant.
- Reassemble the gun.

5. Troubleshooting
- Uneven Spray Pattern: Check for clogged air cap holes or a damaged nozzle. Ensure consistent air pressure.
- Paint Spitting: May indicate insufficient paint in the cup, loose nozzle/air cap, or a partially clogged fluid tip.
- Excessive Overspray: Reduce air pressure or adjust the fan pattern. Ensure proper thinning of paint.
- Leaks: Check all connections for tightness. Inspect O-rings and seals for damage and replace if necessary.
- No Paint Flow: Verify paint viscosity, check for clogs in the nozzle or fluid passage, and ensure the needle is moving freely.
