- Use the provided viscosity measuring cup to check the material's viscosity. If too thick, thin the material according to the manufacturer's recommendations.
- Filter the prepared material to remove any lumps or impurities that could clog the nozzle.
3.2 Assembling the Paint Gun
- Ensure the paint gun is unplugged from the power supply.
- Select the appropriate nozzle for your material and desired spray pattern.
- Attach the spray head to the main unit by twisting it securely.
- Fill the paint container with the prepared material. Do not overfill.
- Screw the filled paint container onto the spray head unit until it is firmly attached.

4. Operating Instructions
4.1 Adjusting Paint Flow
The paint flow can be adjusted to suit the material and desired coverage. Rotate the paint flow regulation knob to increase or decrease the material output.

4.2 Adjusting Spray Pattern
The air outlet cap can be adjusted to achieve vertical, horizontal, or circular spray patterns. Rotate the air cap to align the desired pattern with the nozzle.
- Vertical Jet: For horizontal surfaces.
- Horizontal Jet: For vertical surfaces.
- Circular Jet: For small areas or corners.

4.3 Spraying Technique
- Hold the paint gun approximately 15-30 cm (6-12 inches) from the surface.
- Maintain a consistent distance and speed for an even finish.
- Start spraying off the workpiece and move across, releasing the trigger off the workpiece to avoid overspray and drips.
- Apply thin, even coats rather than one thick coat. Allow adequate drying time between coats.

6. Troubleshooting
Refer to the table below for common issues and their solutions.
| Problem | Possible Cause | Solution |
|---|---|---|
| No spray or weak spray | Clogged nozzle, material too thick, empty container, air cap blocked. | Clean nozzle with purification needle, thin material, refill container, clean air cap. |
| Uneven spray pattern | Partially clogged nozzle, incorrect air cap adjustment, inconsistent spraying technique. | Clean nozzle, adjust air cap correctly, practice spraying on scrap material. |
| Material dripping from nozzle | Nozzle not tightened, material too thin, worn nozzle. | Tighten nozzle, adjust material viscosity, replace nozzle if worn. |
| Motor runs but no spray | Suction tube blocked, air intake blocked. | Clean suction tube, ensure air intake is clear. |
