Selection Charts Selection Charts TERMS Proper Needle/Nozzle Selection Light Fluid: Up to 18 seconds with No. 2 Zahn cup (20 centipoise) 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 triggered at a fluid pressure of 5–20 psi (0.035–0.14 MPa, 0.35–1.4 bar). Medium Fluid:19 to 28 seconds with No.

Installation Installation This spray gun can spray most coatings or finishes currently being used for small component plastic, wood and metal finishing applications, while easily operating from paint delivery systems, such as pressure pots or remote pumps for production line operation. The air regulator must have a minimum air flow capacity of 30 scfm at 100 psi (0.7 MPa, 7.0 bar) air pressure. Ventilate Spray Booth Configure Gun and Manifold Guns with Manifold See FIG. 1.
Installation Guns without Manifold Pump/Fluid Supply The gun is shipped ready for use in a circulating system, with a fitting installed in each fluid port. Connect the fluid supply line to one fluid inlet fitting (15) and the fluid return line to the other. Ground the pump by connecting a ground wire and clamp between the fluid supply and a true earth ground as instructed in your separate pump instruction manual.
Installation Mount Gun Reciprocating Arm Rod Mount To mount the gun on a reciprocating arm rod [0.75 in. (19 mm) diameter maximum], insert the bar (A) through the hole in the manifold as shown in FIG. 3. NOTE: Use the 1/8 in. alignment slot (P) to assist in orienting the gun. Secure the gun to the bar by tightening the mounting screw (B). C Guns with manifold TI14434A C A B P TI14433A FIG. 3: Reciprocating Arm Mount Stationary Support To mount the gun on a stationary support, refer to FIG.
Setup Setup Connect Air Line NOTE: • • • 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. 5. You must install a separate air pressure regulator (F) on the CYL, FAN, and ATOM air lines to control air pressure to the gun. See FIG. 6 and FIG. 7.

Setup Connect Fluid Hose NOTE: Before connecting the fluid line, blow it out with air and flush it with solvent. Use solvent that is compatible with the fluid to be sprayed. Install a fluid regulator (L) on the fluid line to control fluid pressure to the gun. See FIG. 8. Install a fluid shutoff valve (M) to shut off the fluid supply to the gun. Filter the fluid line of coarse particles and sediment to avoid clogging the fluid nozzle and causing finishing defects. Inline fluid filter 24B707 is available.
Setup Flush Spray Gun Adjust Spray Pattern Before running any paint through the spray gun: 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. 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. See Clean and Flush Gun, page 22. 2. Perform Pressure Relief Procedure, page 20.
Setup NOTE: HVLP 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 11 for maximum HVLP manifold inlet pressures. To measure pressure at the air cap, use the appropriate HVLP Pressure Verification Kit. L ti7019a FIG. 11: Fluid Pressure Regulator NOTE: A larger fluid nozzle at a reduced fluid pressure will maintain the same flow rate, but the fluid stream (velocity) will slow down.
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 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 TI14439A ti8174a FIG.
Operation Daily Gun Care NOTICE 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. NOTICE 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; wring out the excess.
Operation General System Maintenance • Follow the Pressure Relief Procedure, page 20. • 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. 9. Dip the end of a soft-bristle brush into a compatible solvent. Do not continuously soak the brush's bristles with solvent and do not use a wire brush.

Troubleshooting Troubleshooting Problem Spray Pattern Cause Solution Normal pattern. No action necessary. Dirty or damaged air cap or fluid nozzle. Rotate air cap (5) 180°. Right Spray Pattern If pattern follows air cap, problem is in air cap. Clean and inspect. If pattern is not corrected, replace air cap. Wrong Heavy top or bottom Spray Pattern Fan pressure too high for viscosity of material being sprayed. If pattern does not follow the air cap, the problem is with the fluid nozzle (4).
Troubleshooting Problem Gun spitting. Cause Air getting into paint stream. Solution Check if fluid source is empty and fill. Tighten fluid nozzle (4). Check fluid nozzle o-ring (3) for damage. Will not spray. Excessive air blowing back. Gun fluid pressure is too high with gun triggered (cannot achieve desired flow rate). Using a low fluid pressure setting, the fluid flow is too high, making it necessary to restrict needle travel to reduce fluid flow.
Service Service screws (16) and remove the gun from the manifold. NOTE: Numbers in parenthesis in the text refer to the reference numbers in the figures and in the parts list. b. Without Manifold: Disconnect the air and fluid hoses. Remove the gun from the mounting arm. 3. Remove the air cap retaining ring (21) and air cap (5). Disassembly 1. Follow the Pressure Relief Procedure, page 20. 2. Remove gun for service: a. With Manifold: Use the 4 mm allen wrench supplied to unscrew the two 4.
Service 6. Use a 1/16 hex wrench to loosen the fluid needle set screw (7a). Remove the needle (6) from the piston (7). 7 1 6 7a 7. Check the fluid needle (6) for damage or excessive wear. Replace the needle if necessary. NOTICE The needle and tip are permanently bonded. To prevent damage to the needle, do not try to separate. 8. Use the 10 mm hex nut driver to remove the fluid packing nut (2). 9. Use the 10 mm wrench to remove the nozzle (4). Reassembly ti14944a 1 Torque to 4.5 to 5.5 in-lb (0.
