3. Operating Instructions
Preparing the Material
Proper material preparation is crucial for optimal HVLP spraying. Most coatings will require thinning to achieve the correct viscosity for spraying. Consult the coating manufacturer's recommendations for thinning ratios. Strain all materials before pouring them into the cup to prevent clogs.
Filling the Cup
Unscrew the cup from the spray gun. Pour the prepared and strained material into the 1-quart cup, ensuring not to overfill. Reattach the cup securely to the spray gun.
Adjusting the Spray Gun
- Fluid Control Knob: Located at the rear of the gun, this knob adjusts the amount of fluid released. Turn clockwise for less fluid, counter-clockwise for more.
- Air Cap Adjustment: The "B" Standard Aircap can be rotated to change the spray pattern from horizontal to vertical or a round pattern. Loosen the retaining ring, rotate the aircap to the desired orientation, and then tighten the ring.
- Air Pressure: The E5011 is designed for use with an HVLP turbine system. Ensure your turbine is operating at the recommended pressure for your material and desired finish.
Spraying Technique
Maintain a consistent distance (typically 6-8 inches) from the surface being sprayed. Move the gun at a steady, even pace, overlapping each pass by approximately 50%. Always trigger the gun after starting your pass and release before ending it to prevent uneven application at the start and end of strokes.
4. Maintenance and Cleaning
Proper cleaning and maintenance are essential for the longevity and optimal performance of your E5011 spray gun. Due to its marine-grade stainless steel components, it offers excellent resistance to various materials.
Daily Cleaning
- After each use, empty any remaining material from the cup.
- Pour a small amount of appropriate cleaning solvent (e.g., water for water-based paints, lacquer thinner for lacquer) into the cup.
- Spray the solvent through the gun until it runs clear.
- Remove the aircap and clean it thoroughly with a brush and solvent.
- Wipe down the exterior of the gun and cup.
Thorough Cleaning and Disassembly
Periodically, or when changing material types, a more thorough cleaning is recommended:
- Perform daily cleaning steps.
- Remove the aircap, fluid nozzle, and needle. Use the provided wrench for the fluid nozzle.
- Clean all disassembled parts using appropriate solvent and cleaning brushes. Pay close attention to the fluid passages and air holes.
- Do not use metal objects to clean the fluid nozzle or aircap holes, as this can damage them.
- Reassemble the gun, ensuring all parts are correctly seated and tightened.
Lubrication
Apply a small amount of Apollo Sprayers gun lube (included sample) to the needle packing and trigger pivot points as needed to ensure smooth operation.
Storage
Store the clean and dry spray gun in a safe, dry place, away from extreme temperatures and direct sunlight. Keep the original packaging for protection.
5. Troubleshooting Guide
This section provides solutions to common issues you might encounter with your E5011 spray gun.
| Problem | Possible Cause | Solution |
|---|---|---|
| Uneven Spray Pattern | Clogged aircap holes; incorrect air cap alignment; material too thick. | Clean aircap thoroughly; ensure aircap is correctly aligned; thin material to recommended viscosity. |
| Paint Spitting | Loose fluid nozzle; damaged fluid nozzle or needle; low material level in cup; non-return valve issue. | Tighten fluid nozzle; inspect and replace damaged parts; refill cup; check non-return valve for proper function. |
| No Paint Flow | Clogged fluid nozzle or needle; empty cup; fluid control knob closed. | Clean fluid nozzle and needle; refill cup; open fluid control knob. |
| Excessive Overspray | Material too thin; gun too far from surface; excessive air pressure. | Adjust material viscosity; reduce distance to surface; ensure correct turbine pressure. |
