Selection Charts Proper Needle/Nozzle Selection Gun Selection The spray gun's needle/nozzle kits range in size to provide different fluid flow rates. HVLP Guns As a general guideline, use the fluid nozzle that will give the required flow with the needle fully triggered at a fluid pressure of 5-20 psi (0.035 MPa, 3.5 bar - 0.14 MPa. 14 bar) For low flow rates or light viscosity fluid, select the smaller nozzle sizes. For high flow rates or high viscosity fluid, select the larger nozzle sizes.

Installation Installation The Automatic XT spray guns were designed to produce the highest quality finish with today's fluids as well as the low V.O.C. (volatile organic compound) fluids of tomorrow. This 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 systems, such as pressure pots or remote pumps for production line operation.
Installation Install Air Fittings Ground Fluid Supply Container 1. Install the supplied 1/4 in. tube fitting into the cylinder (CYL) air port. 2. Install 3/8 in. tube fittings into the atomization (ATOM) air port and the fan (FAN) air port. CYL Ground Object Being Sprayed Ground the object that is being sprayed according to local code. Ground Solvent Pails Ground all solvent pails that are used when flushing according to local code. Use only metal pails, which are conductive.
Installation Mount Gun 2. Secure the gun to the support with two M5 x 0.8 capscrews (C). The screws must be long enough to engage the threaded holes in the gun manifold to a depth of 1/4 in. (6 mm). 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 FIG. 5. Use the 1/8 in. alignment pin (P) to assist in orienting the gun. 2.
Setup Setup Connect Air Line Connect Fluid Hose You must install an air pressure regulator (F) on each gun air line to control air pressure to the gun. See FIG. 8. 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 appearance of your finished workpiece. See FIG. 8.
Setup Flush Spray Gun KEY N Cylinder Air Inlet: accepts 1/4 in. (6.3 mm) O.D. tubing P Atomization Air Inlet: 3/8 in, (9.5 mm) O.D. tubing R Fan Air Inlet: 3/8 in. (9.5 mm) O.D, tubing S Fluid Inlet: 1/4 npsm T Fluid Outlet (circulating gun only): 1/4 npsm Before running any paint through the spray gun: Side Mounted Manifold Ports 1. Flush the gun with a solvent that is compatible with the fluid to be sprayed, using the lowest possible fluid pressure and a grounded metal container. 2.
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. The spray gun fluid flow is controlled by the fluid pressure regulator and the fluid control knob. Use the fluid pressure regulator to adjust the general fluid flow and the fluid control knob to make precise fluid flow adjustments. CAUTION Use caution when operating the fluid control valve near the closed position.
Setup F TI01997 FIG. 13: Air Pressure Regulator 3. Test the spray pattern atomization while keeping the gun a consistent distance, about 6 to 8 inches (150 to 200 mm), from the test piece. Check the atomization quality. Increase the gun atomizing air supply pressure with the air pressure regulator in 5 psi (34 kPa, 0.3 bar) increments until you obtain the desired atomization. For the best transfer efficiency, use the lowest setting needed to achieve desired finish quality. 4.
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 pressure. To achieve best results when applying fluid: • Keep gun perpendicular and 6 to 8 in. (150 to 200 mm) from object being sprayed. • Use smooth, parallel strokes across surface to be sprayed with 50% overlap. Incorrect TI8174a FIG.
Daily Gun Care Daily Gun Care CAUTION Methylene chloride with formic or propionic acid is not recommended as a flushing or cleaning solvent with this gun as it will damage aluminum and nylon components. CAUTION 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. Do not point the gun up while cleaning it. Do not wipe the gun with a cloth soaked in solvent; ring out the excess.
Daily Gun Care General System Maintenance • Perform Pressure Relief Procedure, page 17. • 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. 10. With the gun pointed down, clean the front of the gun, using the soft-bristle brush and solvent. 11.
Troubleshooting Troubleshooting 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. Refer to Spray Pattern Troubleshooting, page 22. General Troubleshooting Problem Fluid leakage through venting holes. Cause Worn packing (17) or needle (5). Solution Replace packing or needle. Air leakage through venting hole. Worn o-ring (9) or gasket (15). Check and replace parts as needed.
Troubleshooting Problem Fluid needle will not trigger. Fluid does not shut off. 311051D Cause Solution Loose or missing fluid needle stop (29) or setscrew (30). Replace stop or tighten setscrew. Air leaking around piston (3). Replace o-ring (8) or piston. Swollen piston o-ring (8). Replace o-ring. Do not immerse piston in solvent. Insufficient air pressure on trigger. Increase air pressure or clean air line. Plug (19) is in incorrect fluid port.
Troubleshooting Spray Pattern Troubleshooting Problem Cause Fluid flow is fluttering while spraying. Fluid nozzle is not tight enough. Solution Tighten fluid nozzle to 60 in-lb (6.8 N•m). O-ring (36) is missing or damaged. Replace o-ring. Fluid filter is clogged. Check fluid filter. Fluid flow fades while spraying high viscosity fluids. Fluid pressure is too low, causing fluid flow to reduce when gun is elevated. Raise fluid pressure at source or use a smaller fluid nozzle.
Service Service 5. Using a 1/16 in. hex wrench loosen the fluid needle set screw (30). Remove the needle stop (29). Items Needed for Service • 1/16 in. Hex Wrench - provided • 3 mm Hex Wrench • Adjustable Wrench • 4 mm Hex Wrench • Pliers • Lubricant part no. 111265; see Accessories, page 33, to order • Compatible Solvent 6. Pull the fluid needle (5) out the back of the gun. 7. Check the fluid needle (5) for damage or excessive wear.
Service b. 13. Remove all o-rings from the piston (3) and stems (T). Check that the stems are solidly in place. If they are loose, replace the entire piston assembly (3). 15. Clean all parts and replace any worn parts. When assembling, lubricate the threads with anti-seize lubricant. 14. Perform the following applicable step: a. Non-circulating guns: Remove the fluid outlet port plug (19), and gasket (22) from the fluid housing (2). Remove the o-ring (21) and backup (20) from the plug.
Service Reassembly 1. Non-circulating guns only: Lubricate the backup ring (20†) and o-ring (21†) and install them on the fluid outlet port plug (19). Install the plug in the fluid outlet port of the fluid housing (2). See FIG. 22. 2. All guns: Reinstall the gasket (22) in the fluid housing (2). 3. Install the o-rings (8*, 9*) on the piston (3). Install the two o-rings (10*, 11*) on each of the piston stems (T). Lubricate all the o-rings, the piston, and the piston stems. 4.
