  • Page 7: Conventional Guns

    Conventional Guns An airspray gun has excellent atomization and high production rates typically with some reduction in transfer efficiency. Proper Needle/Nozzle Selection The spray gun's needle/nozzle kits range in size to provide different fluid flow rates. As a general guideline, use the fluid nozzle that will give the required flow with the needle fully trig- gered at a fluid pressure of 5–20 psi (0.035–0.14 MPa, 0.35–1.4 bar).

  • Page 8: Air Flow

    Air Flow Air Flow See the chart to determine air consumption. Add the air consumption values shown for the atom- izing air and fan air pressures to get the total air consumption. For example, air cap 24B544 with 20 psi atomizing air pressure uses 3 scfm atomizing air. A 30 psi fan inlet pressure adds 5 scfm fan air for a total of 8 scfm air consumption.

  • Page 10: Installation

    Installation Installation The Automatic AirPro spray gun can spray most coatings or finishes currently being used for automotive, industrial, aerospace, marine, wood, plastic and architectural applications, while easily operating from paint delivery sys- tems, such as pressure pots or remote pumps for production line operation.

  • Page 11: Install Air Fittings

    Install Air Fittings 1. Install the supplied 1/4 in. tube fitting into the cylinder (CYL) air port. 2. Install 3/8 in. tube fittings into the atomiza- tion (ATOM) air port and the fan (FAN) air port. . 2: Air Fittings Ground System The following grounding instructions are mini- mum requirements for a system.

  • Page 12: Mount Gun

    Installation Mount Gun Reciprocating Arm Rod Mount To mount the gun on a reciprocating arm rod [0.5 in. (13 mm) diameter maximum]: 1. Insert the mounting bar (A) through the hole in the manifold as shown in F NOTE: Use the 1/8 in. alignment pin (P) to assist in orienting the gun.
  • Page 13 Retrofit Adapter Plate The retrofit adapter plate enables the manifold to be attached to a variety of bolt patterns. To mount the gun using the retrofit adapter plate (Kit 288197; See Accessories, page 34): 1. Mount adapter plate to manifold using the three screws provided with the kit.

  • Page 14: Setup

    Setup Setup Connect Air Line NOTE: • You must install an air pressure regula- tor (F) on each gun air line to control air pressure to the gun. See F • If your regulated air source does not have a filter, install an air filter (G) on each air line to ensure a dry, clean air supply to the gun.

  • Page 16: Adjust Spray Pattern

    Setup Adjust Spray Pattern Do not exceed 100 psi (0.7 MPa, 7 bar) maximum fluid and air pressure. Higher pressures can cause parts to rupture and result in serious injury. Use the fluid pressure regulator to adjust the spray gun fluid flow. Some models are equipped with a fluid control knob to make pre- cise fluid flow adjustments.
  • Page 17 NOTE: HVLP and Compliant Gun Limits HVLP Guns: local laws may limit the maximum pressure to 10 psi (70 kPa, 0.7 bar) at the air cap for compliance. See the table on page 7 for maximum HVLP/Compliant manifold inlet pressures. To measure pressure at the air cap, use the appropriate HVLP Pressure Verifica- tion Kit.

  • Page 18: Operation

    Operation Operation Pressure Relief Procedure 1. Turn off all bleed type air valves and all other air and fluid supplies to the gun. 2. Trigger the gun into a grounded metal waste container to relieve air and fluid pres- sure. .

  • Page 19: Daily Gun Care

    Daily Gun Care NOTICE Methylene chloride with formic or propi- onic acid is not recommended as a flush- ing or cleaning solvent with this gun as it will damage aluminum and nylon compo- nents. Solvent left in gun air passages could result in a poor quality paint finish. Do not use any cleaning method which may allow solvent into the gun air passages.

  • Page 20: General System Maintenance

    Operation General System Maintenance • Perform Pressure Relief Procedure, page 18. • Clean the fluid and air line filters daily. • Check for any fluid leakage from the gun and fluid hoses. Tighten fittings or replace equipment as needed. • Flush the gun before changing colors and whenever you are done operating the gun.

  • Page 21: Troubleshooting

    Troubleshooting NOTE: Check all possible remedies in the trou- bleshooting charts before disassembling the gun. General Troubleshooting Problem Fluid leakage through venting holes. Air leakage through venting hole. Worn o-ring (9) or gasket (15). Air leakage from back of gun. Air does not trigger.

  • Page 22: Spray Pattern Troubleshooting

    Troubleshooting Problem Fluid needle will not trigger. Fluid does not shut off. Spray Pattern Troubleshooting Problem Fluid flow is fluttering while spray- ing. Fluid flow fades while spraying high viscosity fluids. Pattern becomes off-set or heavy on ends. Gun fluid pressure is too high with gun triggered.
