WARNING INJECTION HAZARD Spray from the gun, hose leaks, or ruptured components can inject fluid into your body and cause an extremely serious injury, including the need for amputation. Splashing fluid in the eyes or on the skin can also cause a serious injury. Fluid injected into the skin might look like just a cut, but it is a serious injury. Get immediate medical attention. Do not point the spray gun at anyone or at any part of the body. Do not put hand or fingers over the spray tip.

Installation Connect the Air Line 1. Install an air line filter (A) to ensure a clean, dry air supply to the gun. Dirt and moisture in the line can ruin the appearance of your finished piece. See Fig. 1. 2. Install an air pressure regulator (L) on the gun air supply line to control the air pressure to the gun. 3. Install an air pressure regulator (D) on the pump air supply line to control air pressure to the pump. 4.
Installation Ground the System WARNING FIRE AND EXPLOSION HAZARD Improper grounding could cause static sparking, which could cause a fire or explosion. To reduce the risk of property damage or serious injury, follow the grounding instructions below. The following grounding instructions are minimum requirements for a system. Your system may include other equipment or objects which must be grounded. Check your local electrical code for detailed grounding instructions for your area and type of equipment.
Operation 6. Lock the gun trigger safety again. Safety WARNING INJECTION HAZARD Remember, this is not an air spray gun. For your safety be sure to read and follow the Warnings on pages 2 and 3 and throughout the text of this instruction manual. Keep the wallet sized warning card 179–960, provided with the gun, with the operator of this equipment at all times. The card contains important treatment information should an injection injury occur. Additional cards are available at no charge from Graco.
Operation How the Air-Assisted Airless Spray Gun Operates The air-assisted airless spray gun combines airless and air spraying concepts. The spray tip shapes the fluid into a fan pattern, as does a conventional airless spray tip. Air from the air cap further atomizes the fluid and completes the atomization of the paint tails into the pattern to produce a more uniform pattern. The pattern adjustment valve controls the width of the pattern.
Operation Pattern Adjustment Knob Adjust the Spray Pattern WARNING INJECTION HAZARD To reduce the risk of component rupture and serious injury, including injection, do not exceed the gun’s maximum fluid working pressure of 950 psi (66 bar) or the maximum working pressure of the lowest rated component in the system. Fig. 4 NOTE: Optional gun parts are available for special applications. See page 20. 1. Set the fluid pressure at 300 psi (21 bar) with the fluid regulator. 2.
Operation Clean the Spray Gun and System Daily Check the Diffuser-seat Operation Weekly WARNING INJECTION HAZARD To reduce the risk of an injection injury or splashing fluid in the eyes or on the skin: Follow the Pressure Relief Procedure on page 7 before cleaning, removing, or installing a spray tip and whenever you are instructed to relieve pressure. Do not wipe fluid buildup off the gun or spray tip until pressure is relieved.
Operation Flush the Gun Daily WARNING INJECTION HAZARD To reduce the risk of a fluid injection injury, follow the Pressure Relief Procedure on page 7 before cleaning, removing, or installing a spray tip and whenever you are instructed to relieve pressure. NOTE: Flush the pump and gun before the fluid can dry in it. If it is available, the flushing procedure provided in the pump or sprayer manual should be used instead of this procedure. 1. Relieve the pressure as instructed on page 7. 2.
Troubleshooting WARNING INJECTION HAZARD To reduce the risk of a fluid injection injury, follow the Pressure Relief Procedure on page 7 before checking or servicing any of the system equipment and whenever you are instructed to relieve pressure. NOTE: Check all possible remedies in the troubleshooting charts before disassembling the gun. Some improper patterns are caused by the improper balance between air and fluid.
