5. Setup

Follow these steps to prepare your paint sprayer for use:

1. Charge Batteries: Ensure both 3000 mAh Lithium-ion batteries are fully charged before use. Insert a charged battery into the sprayer's handle until it clicks into place.
2. Prepare Paint: Dilute your paint to the appropriate viscosity using the provided measuring cup. The maximum recommended viscosity is 80 Din-s. Pour the diluted paint into the 1000ml container.



3. Assemble Sprayer: Attach the paint container to the sprayer unit by screwing it on firmly. Ensure it is securely locked to prevent leaks.
4. Select Nozzle: Choose the appropriate nozzle size (1.0mm, 1.8mm, or 2.5mm) based on your paint type and desired spray pattern. The 1.0mm nozzle is suitable for thinner materials, while the 2.5mm nozzle is for thicker paints.



5. Adjust Spray Pattern: Rotate the air cap to select your desired spray pattern: vertical, horizontal, or circular.
6. Test Spray: Before applying paint to your project, perform a test spray on a piece of cardboard or scrap material to ensure the desired pattern and flow are achieved. Adjust the flow regulator as needed.

6. Operating Instructions

Once assembled and filled, your ONEVAN Cordless Paint Sprayer is ready for use.

1. Power On: Press the trigger to start the sprayer. The power indicator lights will show the battery level.
2. Adjust Flow Rate: Use the flow adjustment knob to control the amount of paint being sprayed. Start with a lower setting and increase as needed.
3. Maintain Distance: Hold the sprayer approximately 6-12 inches (15-30 cm) from the surface, depending on the desired coverage and paint type.
4. Even Strokes: Move the sprayer in smooth, even strokes, overlapping each pass slightly to ensure uniform coverage. Avoid tilting the sprayer excessively to prevent paint starvation or uneven application.
5. Anti-Backflow Feature: The anti-backflow design allows for spraying ceilings and other overhead surfaces without paint leaking back into the unit.



6. Applications: This sprayer is suitable for a wide range of indoor and outdoor projects, including painting fences, doors, furniture, cabinets, walls, and ceilings.
