1. Introduction
Thank you for choosing the AUARITA NOVA-1 LVMP Professional Pneumatic Paint Spray Gun. This manual provides essential information for the safe and effective operation, maintenance, and troubleshooting of your new spray gun. The NOVA-1 is a high-quality, gravity-feed spray gun designed for commercial manufacturing applications, featuring a 1.3mm nozzle for precise and efficient paint application.
2. Safety Instructions
Always follow these safety precautions to prevent injury or damage to the equipment:
- Wear appropriate personal protective equipment (PPE), including a respirator, safety glasses, gloves, and protective clothing.
- Ensure adequate ventilation in the work area to prevent the accumulation of hazardous fumes.
- Never point the spray gun at yourself or others.
- Always disconnect the air supply before cleaning, performing maintenance, or when the gun is not in use.
- Use only compatible paints and solvents. Refer to the paint manufacturer's instructions for proper handling and safety.
- Keep the spray gun away from open flames, sparks, and other ignition sources.
- Do not exceed the maximum recommended air pressure.
- Keep children and unauthorized personnel away from the work area.
3. Product Components
The AUARITA NOVA-1 spray gun comes with the following main components and accessories:
- Spray Gun Body: Main housing with trigger and control knobs.
- Gravity Feed Cup: 600ml top-mounted plastic cup for paint.
- Nozzle Set (1.3mm): Includes air cap, fluid nozzle, and needle.
- Air Inlet: Connection point for air hose.
- Air Pressure Regulator: (Often integrated or separate, not explicitly listed but implied by pressure specs).
- Accessories: Cleaning brush, wrench, filter, O-ring, air coupler.
4. Setup and Assembly
- Attach Air Hose: Connect your air compressor hose to the air inlet of the spray gun. Ensure a secure, leak-free connection.
- Prepare Paint: Mix and thin your paint according to the paint manufacturer's specifications. Strain the paint to remove any impurities that could clog the nozzle.
- Fill Gravity Cup: Pour the prepared paint into the 600ml gravity feed cup and securely attach it to the spray gun.
- Adjust Air Pressure: Set your air compressor to deliver the optimal working pressure of 2.0 Bar (29 Psi) at the gun's inlet.
- Initial Adjustments:
Figure 2: Nozzle and Control Knobs - Fluid Control Knob: Adjusts the amount of paint flowing through the gun. Turn clockwise for less paint, counter-clockwise for more.
- Fan Pattern Control Knob: Adjusts the shape of the spray pattern from round to wide fan.
- Air Flow Control Knob: Fine-tunes the air pressure at the gun.
5. Operating Instructions
- Test Spray: Before spraying your workpiece, perform a test spray on a scrap piece of material to check the pattern and adjust settings as needed.
- Spray Distance: Maintain a consistent spray distance of approximately 170 mm from the surface.
- Spray Pattern: The pattern width can be adjusted between 260 - 300 mm. Adjust the fan pattern control knob to achieve the desired coverage.
- Spraying Technique:
Figure 3: Ideal Spray Pattern and Distance - Use smooth, even strokes, moving your arm rather than just your wrist.
- Overlap each pass by about 50% to ensure even coverage.
- Release the trigger at the end of each stroke to avoid paint buildup.
- Optimal Pressure: The gun is designed for optimal performance at 2.0 Bar (29 Psi). Adjusting pressure can affect atomization and pattern.
6. Maintenance and Cleaning
Proper cleaning and maintenance are crucial for the longevity and performance of your spray gun.
- After Each Use:
- Disconnect the air supply.
- Empty any remaining paint from the gravity cup.
- Pour a small amount of appropriate cleaning solvent into the cup and spray it through the gun until clear solvent emerges.
- Remove the air cap and clean it thoroughly with a brush and solvent.
- Clean the fluid nozzle and needle tip.
- Periodic Deep Cleaning:
- Disassemble the air cap, fluid nozzle, and needle.
- Soak these parts in cleaning solvent.
- Use the provided cleaning brush to remove any dried paint or residue from all passages.
- Inspect O-rings and seals for wear and replace if necessary.
- Reassemble the gun, ensuring all parts are tightened correctly.
- Lubrication: Apply a small amount of spray gun lubricant to the needle packing and trigger pivot points periodically.
Caution: Never use metal objects to clean the nozzle or air cap openings, as this can damage them and affect spray performance.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Uneven Spray Pattern | Clogged air cap or fluid nozzle; incorrect air pressure; damaged air cap. | Clean air cap and nozzle; adjust air pressure to 2.0 Bar; replace damaged parts. |
| Sputtering or Pulsating Spray | Low paint level; loose fluid nozzle; clogged air vent in cup lid; insufficient air supply. | Refill paint cup; tighten fluid nozzle; clear air vent; check air compressor output. |
| Paint Leaking from Nozzle | Worn needle packing; loose fluid nozzle; damaged needle. | Replace needle packing; tighten fluid nozzle; replace needle. |
| Poor Atomization | Too low air pressure; paint too thick; clogged air cap. | Increase air pressure; thin paint appropriately; clean air cap. |
