Selection Charts 6 313516C High Wear Applications ✠ Needle tip and nozzle exit constructed from tungsten carbide. Wood Applications Gun Selection HVLP Guns An HVLP gun is a high transfer efficiency gun that limits the air pressure at the air cap to 10 psi (0.07 MPa, 0.7 bar) maximum. In some areas, an HVLP gun is required for compliance with envi[...]

Selection Charts 313516C 7 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[...]

Air Flow 8 313516C 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 a[...]

Install 3/8 in. tube fittings into the atomiza- tion (ATOM) air port and the fan (FAN) air port. Ground System The following grounding instructions are mini- mum requirements for a system. Your system may include other equi[...]

Installation 12 313516C 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 IG .3 . NOTE: Use the 1/8 in. alignment pin (P) to assist in orienting the gun. 2. Secure the gun to the bar by tightening the mou[...]

Installation 313516C 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. (See F IG . 5 and the mounting hole l[...]

Setup 14 313516C 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 IG .6 . • 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. Dirt and moisture can ruin the app[...]

Setup 313516C 15 Flush Spray Gun Before running any paint through the spray gun: 1. Flush the gun with a solvent that is compat- ible with the fluid to be sprayed, using the lowest possible fluid pressure and a grounded metal container. 2. Perform Pressure Relief Procedure ; see page 18. Position Air Cap Air caps are factory-set with the alignment [...]

Setup 16 313516C Adjust Spray Pattern 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. Follow these steps to establish the correct fluid flow and air flow: 1. To achieve desired flow, adjust the fluid flow using the fluid pressure regula[...]

Setup 313516C 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. See Accessories , [...]

Operation 18 313516C 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. Apply Fluid The spray gun has a built-in lead and lag oper- ation. When triggered, the gun begins emitting air b[...]

Operation 313516C 19 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. NOTICE Solvent left in gun air passages could result in a poor quality paint finish. Do not use any cleaning method which may allow solv[...]

Operation 20 313516C 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.
