4. Operating Instructions

The Auarita HVLP H-887P offers precise control for various painting applications.

4.1. Adjustments

This spray gun features three main adjustment controls:

• Fluid Control Knob (Paint Quantity): Located at the rear of the gun, this knob adjusts the amount of paint released. Turn clockwise to decrease paint flow, counter-clockwise to increase.
• Fan Pattern Control Knob (Spray Pattern): Typically located on the side of the gun, this knob adjusts the shape of the spray pattern from a round spot to a wide fan. Turn to achieve the desired pattern.
• Air Pressure Control Knob: Often located at the bottom or side, this knob regulates the air pressure delivered to the gun. Adjust according to paint viscosity and desired finish. Recommended operating pressure is 3-4 bars.

4.2. Spraying Technique

1. Test Spray: Always perform a test spray on a scrap piece of material to fine-tune your adjustments before painting your actual workpiece.
2. Distance: Maintain a consistent distance of approximately 6-8 inches (15-20 cm) from the surface.
3. Movement: Use smooth, even strokes, moving your entire arm rather than just your wrist. Overlap each pass by about 50% to ensure even coverage.
4. Trigger Control: Fully depress the trigger for each pass and release it at the end of the pass. Avoid feathering the trigger.
5. Coats: Apply multiple thin coats rather than one thick coat to prevent runs and sags, allowing adequate drying time between coats.

5. Maintenance and Cleaning

Regular cleaning and maintenance will extend the life of your spray gun and ensure consistent performance. Clean the gun immediately after each use.

1. Empty Paint Cup: Pour any remaining paint back into its original container.
2. Initial Rinse: Add a small amount of appropriate cleaning solvent (e.g., paint thinner for oil-based paints, water for water-based paints) to the paint cup. Spray through the gun into a waste container until the solvent runs clear.
3. Disassemble: Disconnect the air supply. Carefully disassemble the air cap, fluid nozzle, and needle.

4. Clean Components: Use a cleaning brush and appropriate solvent to thoroughly clean the paint cup, air cap, fluid nozzle, and needle. Pay close attention to small holes and passages. Do not use metal objects to clean the nozzle or air cap, as this can damage them.
5. Clean Gun Body: Wipe down the exterior of the gun body with a solvent-dampened cloth. Avoid immersing the entire gun in solvent.
6. Lubrication: Apply a small amount of spray gun lubricant to the needle packing and air valve packing after cleaning to ensure smooth operation.
7. Reassemble: Reassemble the spray gun components, ensuring they are properly seated and tightened.
