4. Setup
- Prepare Work Area: Ensure the work area is clean, well-ventilated, and adequately protected from overspray using drop cloths or masking tape.
- Connect Hose: Connect the 11.5-foot air hose to the X-Boost Power Box and the spray gun handle. Ensure connections are secure.
- Select Nozzle: Choose either the iSpray Nozzle for larger surfaces or the Detail Finish Nozzle for smaller, more intricate work. Attach the selected nozzle to the spray gun handle.
- Prepare Material: Fill the material cup with your chosen paint or stain. The FLEXiO 5000 is designed to spray most unthinned materials directly from the can. However, for optimal results, especially with thicker coatings, a small amount of thinning (up to 10%) may be beneficial. Always strain your paint to prevent clogs.
- Attach Material Cup: Securely attach the filled material cup to the spray gun assembly.

5. Operating Instructions
5.1 Adjusting the Sprayer
The FLEXiO 5000 offers complete adjustability to suit various project needs and materials.
- X-Boost Power Dial: Located on the gun handle, this dial adjusts the air pressure level. Turn it to increase or decrease power based on material thickness and desired finish.
- Material Flow Control: Adjust this knob to control the amount of paint flow. Increase for faster coverage, decrease for finer control and less material.
- Adjustable Pattern Width: Rotate the air cap ears to change the spray pattern from horizontal to vertical, or use the round pattern for small areas.


5.2 Spraying Technique
- Practice: Always practice on a scrap piece of material to get a feel for the sprayer and to fine-tune your settings before applying to your actual project.
- Distance: Maintain a consistent distance (typically 6-10 inches) from the surface.
- Movement: Use smooth, even strokes, moving your entire arm rather than just your wrist. Overlap each pass by about 50% to ensure even coverage.
- Coats: Apply multiple thin coats rather than one thick coat to avoid runs and drips, allowing adequate drying time between coats.

6. Maintenance and Cleaning
Proper cleaning after each use is crucial for maintaining the performance and longevity of your sprayer. The Lock-n-Go split gun design facilitates quick and easy cleaning.
- Disconnect Power: Always unplug the sprayer from the power source before cleaning.
- Empty Material Cup: Pour any remaining material back into its original container.
- Disassemble: Separate the spray gun from the handle and disassemble the nozzle components (air cap, fluid nozzle, etc.).
- Clean Components: Wash all parts that came into contact with paint using warm soapy water for water-based materials, or appropriate solvent for oil-based materials. Use the provided cleaning brushes to thoroughly clean all passages and orifices.
- Rinse: Rinse all components thoroughly with clean water or solvent until all paint residue is removed.
- Dry and Reassemble: Allow all parts to dry completely before reassembling. Store the sprayer in its protective carrying case.

7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No spray or weak spray | Clogged nozzle, insufficient material, low air pressure, material too thick. | Clean nozzle, refill cup, increase X-Boost power, thin material if necessary. |
| Uneven spray pattern or spitting | Partially clogged nozzle, damaged air cap, incorrect air cap orientation, material drying on tip. | Thoroughly clean nozzle and air cap, ensure air cap is correctly aligned, wipe tip frequently during use. |
| Runs or drips | Too much material flow, spraying too close, moving too slowly. | Reduce material flow, increase spraying distance, move faster, apply thinner coats. |
| Excessive overspray | Too much air pressure, spraying too far from surface. | Reduce X-Boost power, spray closer to the surface. |
| Motor not starting | No power, faulty connection. | Check power outlet, ensure all connections are secure. |
