Avanti AV-HVLP-5S - User Manual

The Avanti 3 & 5 Stage HVLP Turbine Paint Sprayers are designed for applying various coatings, offering features for both professional and household use. This manual provides comprehensive instructions for safe operation, setup, maintenance, and troubleshooting.

Function Description:

These HVLP (High Volume Low Pressure) turbine paint sprayers are designed to atomize paint using a high volume of air at low pressure, resulting in a finer finish, reduced overspray, and more efficient material transfer compared to conventional spray guns. The "3 & 5 Stage" designation refers to the number of turbine stages, which typically correlates with the power and air volume produced, allowing for spraying a wider range of materials, from thin stains to thicker latex paints. The device is intended for applying water-based or oil-based paints and for cleaning with water or mineral spirits. It is crucial to clean the spray gun body and cup immediately after every use and when it will be idle for more than 30 minutes, as delayed or inadequate cleaning will permanently clog the spray gun. The turbine assembly should be kept in a well-ventilated area, at least 20 feet (6.1m) from the spraying area. The product is not a toy and should be kept out of reach of children.

Extension Cord Requirements (120/240 Volt): The manual provides a detailed table for recommended minimum wire gauge based on nameplate amperes and cord length (25', 50', 75', 100', 150'). For example, for 0-2.0 amperes, an 18-gauge cord is recommended for lengths up to 100', and a 16-gauge for 150'. For 16.1-20.0 amperes, a 12-gauge cord is needed for 25' and 10'. These recommendations are based on limiting line voltage drop to five volts at 150% of the rated amperes.
Grounding: The product is designed for use on a nominal 120-V circuit and has a three-prong grounding plug. It must be connected to a properly grounded outlet.

Usage Features:

Setup and Assembly: The manual details how to thread the air hose onto the sprayer's outlet and attach the spray gun to the air hose using the coupler. The 58149 model includes an additional whip hose.
Accessory Storage: A compartment on the back of the sprayer is provided to store two nozzle-needle sets and a nozzle wrench.
Paint Preparation and Filling: Proper paint mixture and thinning according to the manufacturer's directions are essential. Paint should be strained through a paint strainer or cheesecloth and the cup filled 3/4 full.
Fluid/Air Adjustment: The Air Control Knob (clockwise until it stops for fully open) and Fluid Control Knob (counterclockwise until two threads are showing) are used to adjust the spray consistency. Adjustments should be made slowly on scrap material.
Fan Pattern Adjustment:
- For 58149, the Lock Ring is loose, and the Air Cap is turned clockwise to select the desired fan pattern while keeping the Fluid Nozzle flush with the Air Cap.
- For 58479, the Lock Ring is loosened by hand until the Air Cap moves freely, then the Air Cap is turned clockwise to select the desired fan pattern, and the Lock Ring is tightened.
- Patterns include Cone, Horizontal, and Vertical.
Spraying Techniques:
- Maintain the spray gun within 45° up or down from the workpiece.
- Keep the cup full to prevent sputtering.
- Move the arm, not just the wrist, pointing the gun directly towards the surface, maintaining an even, steady distance (6" to 8") and speed.
- Avoid pivoting the wrist or waving the gun like a fan.
- Apply two thin coats rather than one thick coat, overlapping 1/3 to 1/2 on the second coat.
- Start moving the spray gun before fully depressing the trigger and release the trigger while still moving the spray gun and after passing the workpiece to avoid paint buildup.
- Check the Fluid Nozzle regularly for dried paint to prevent clogs.
Safety Features:
- Thermal Overload Switch: The motor has thermal overload protection. If the unit overheats, allow approximately 30 minutes for it to cool, then press the Thermal Overload Switch.
- Air Filter Light (58149 only): If this light comes on, check the air filters.
- Explosion Risk: Do not spray flammable liquids or liquids with a flash point less than 38°C (100°F). Work away from ignition sources and keep a class ABC fire extinguisher nearby.
- Electric Shock Risk: Connect to a GFCI-protected outlet only. Do not expose to rain.
- Injection Risk: Do not point the spray gun at people or animals. Seek medical attention immediately in case of skin injection.
- Hazardous Materials: Do not spray pesticides, acids, corrosive materials, fertilizers, or toxic chemicals.
- Personal Protective Equipment: Wear protective paint spraying gloves, a NIOSH-approved respirator, ANSI-approved safety goggles, non-skid safety shoes, and a hard hat as applicable.

Maintenance Features:

Pre-Cleaning: Before first use, the spray gun should be thoroughly cleaned using mineral spirits or water to remove testing and corrosion prevention material. The process involves filling the cup with solvent, spraying into a waste container, and then disassembling and drying the components.
Post-Cleaning (After Every Use):
- Use solvent recommended by the paint manufacturer.
- Remove paint from the cup and dispose of it properly.
- Add solvent to the cup, shake, and spray into a waste container until clean solvent comes out.
- Disassemble the spray gun: remove the Lock Ring, Air Cap, Air Valve, Spring (58149 only), Fluid Needle, Fluid Nozzle (using the included wrench), Fluid Control Knob, and Fluid Needle Spring.
- Inspect parts and soak them in solvent. Use the included brush and nozzle cleaning tool to remove paint. Do not bend the Fluid Needle.
- Wipe down the spray gun body with a clean cloth and solvent.
- Ensure all parts are dry and free of residual paint before reassembly.
- Crucially, do not use any kind of lubricant, as it will mix with paint and cause poor results.
Air Filter Maintenance:
- Remove Air Inlet Covers by turning counterclockwise.
- Remove and inspect Sponge Pre-Filters, Sponge Filters, and Paper Filters.
- Clean Sponge Filters by washing in warm water and mild detergent, rinsing, squeezing out excess water, and allowing to dry completely.
- Clean Paper Filters by blowing dust out with pressurized air (no more than 15 PSI) in a well-ventilated area, wearing safety goggles, a dust mask/respirator, and heavy-duty work gloves.
- Replace filters if they cannot be cleaned sufficiently.
- Install filters and replace Air Inlet Covers by turning clockwise.
Air Tube Replacement:
- Remove the Air Tube from the spray gun and cup lid.
- Orient the new Air Tube so the tapered end of the Check Valve faces down.
- Push the ends of the new Air Tube over the fittings on the spray gun and cup lid. A small amount of water can be used as a lubricant.
Troubleshooting: The manual includes a comprehensive troubleshooting chart for common spray pattern issues (heavy center, light center, heavy top/bottom, pattern on right/left only, jerky/fluttering spray) and other problems (sputtering spray, will not spray, overspray, air filter light on). It lists possible causes and likely solutions for each issue.
Storage: Store the sprayer in a dry, secure area out of reach of children.
Waste Disposal: Dispose of waste according to solvent manufacturer's directions and local hazardous waste standards.
