Setup

1. Preparing the Paint

Proper paint preparation is crucial for optimal spraying results and to prevent clogging.

1. Viscosity Test: Use the included viscosity measuring cup to test the paint. Fill the cup with paint and time how long it takes for the paint to flow out completely. The recommended flow time is 20-45 seconds (maximum 100 DIN-Secs).
2. Thinning: If the paint is too thick (flows out too slowly), thin it according to the paint manufacturer's recommendations. Use the appropriate thinner for your paint type (e.g., water for water-based paints, mineral spirits for oil-based paints). Mix thoroughly.
3. Filtering: Pour the prepared paint through a filter (e.g., a paint strainer or universal filter paper) into the paint cup to remove any impurities that could clog the nozzle.

2. Assembly

Ensure the sprayer is unplugged before assembly.

1. Attach the paint cup to the main sprayer body by screwing it firmly into place.
2. Select the appropriate nozzle for your paint and project. The sprayer comes with 1.2mm, 1.8mm, 2.5mm, and 3.0mm nozzles.
3. Insert the chosen nozzle into the front assembly and secure it with the union nut.

3. Nozzle Selection and Spray Pattern Adjustment

The sprayer offers three spray patterns and four nozzle sizes for versatility.

• Nozzle Sizes: Choose a smaller nozzle (e.g., 1.2mm, 1.8mm) for thinner paints and finer finishes. Use larger nozzles (e.g., 2.5mm, 3.0mm) for thicker paints and broader coverage.
• Spray Pattern Adjustment: Rotate the 'Change Shape Knob' (air cap ears) on the front of the sprayer to select your desired pattern:

• Vertical 90°: For horizontal surfaces.
• Circular 45°: For small areas or detailed work.
• Horizontal 180°: For vertical surfaces.

Operating Instructions

1. Filling the Paint Container

1. Ensure the paint is properly thinned and filtered as described in the Setup section.
2. Unscrew the paint cup from the sprayer.
3. Carefully pour the prepared paint into the 1000ML paint cup. Do not overfill.
4. Screw the paint cup back onto the sprayer body securely.

2. Starting the Sprayer

1. Plug the power cord into a suitable electrical outlet.
2. Press the 'Press Button' (power switch) to turn on the sprayer. The motor will start.

3. Spraying Technique

Practice on a piece of cardboard or scrap material before spraying your actual project.

• Distance: Maintain a consistent distance of 10-30 cm (4-12 inches) from the surface.
• Movement: Move the sprayer in smooth, even strokes, parallel to the surface. Overlap each pass by about one-third to ensure even coverage.
• Trigger Control: Press the trigger fully to start spraying and release it at the end of each stroke.

4. Adjusting Flow Rate

The 'Flow Control Knob' allows you to precisely control the amount of paint being sprayed.

Image: Illustrates the 'Adjustable Valve Flow Control Knob' and how to rotate it to adjust the paint flow rate from 0ml/min to 1000ml/min, allowing for precise control over paint output.

• Rotate the knob clockwise to decrease the paint flow.
• Rotate the knob counter-clockwise to increase the paint flow.
• Adjust the flow rate to match the paint viscosity and desired coverage. Start with a lower setting and gradually increase if needed.

Maintenance and Cleaning

Thorough cleaning after each use is essential to prevent paint from drying and clogging the sprayer, ensuring its longevity and performance.

1. Disconnect Power: Always unplug the sprayer from the power outlet before cleaning.
2. Empty Paint Cup: Unscrew the paint cup and pour any remaining paint back into its original container.
3. Initial Rinse: Fill the paint cup with the appropriate cleaning solution (water for water-based paints, mineral spirits for oil-based paints). Reattach the cup and spray the cleaning solution into a waste container until it runs clear.
4. Disassemble and Clean:
   • Unscrew the paint cup and detach the front nozzle assembly.
   • Thoroughly clean the paint cup, suction tube, and nozzle assembly with the cleaning solution and the provided cleaning brush.
   • Use the cleaning needle to clear any blockages in the nozzle orifice.
