Warnings Warnings The following warnings are for the setup, use, grounding, maintenance, and repair of this equipment. The exclamation point symbol alerts you to a general warning and the hazard symbol refers to procedure-specific risk. Refer back to these warnings. Additional, product-specific warnings may be found throughout the body of this manual where applicable. WARNING EQUIPMENT MISUSE HAZARD Misuse can cause death or serious injury.
Warnings WARNING PRESSURIZED EQUIPMENT HAZARD Fluid from the gun/dispense valve, leaks, or ruptured components can splash in the eyes or on skin and cause serious injury. • Follow Pressure Relief Procedure in this manual, when you stop spraying and before cleaning, checking, or servicing equipment. • Tighten all fluid connections before operating the equipment. • Check hoses, tubes, and couplings daily. Replace worn or damaged parts immediately.
Installation Installation Ventilate Spray Booth Non-circulating System: 1. Apply anti-seize lubricant 222955 to the threads and mating faces of manifold (101), plug (109), and elbow (107), supplied unassembled. Check and follow all National, State, and Local codes regarding air exhaust velocity requirements. Check and follow all local safety and fire codes. Configure Gun and Manifold (Order manifold separately. See Accessories, page 26.) Manifolds 241161 and 241162 2.
Installation Install Air Fittings Ground Air Compressors and Hydraulic Power Supplies 1. Install 1/4 in. tube fitting into the cylinder (CYL) air port. 2. Install plugs into the atomization (ATOM) air port and the fan (FAN) air port. CYL ATOM Ground them according to the manufacturer recommendations. Ground Air, Fluid, and Hydraulic Hoses Connected to Pump Use only electrically conductive hoses with a maximum of 100 ft (30.5 m) combined hose length to ensure grounding continuity.
Installation Mount Gun Stationary Support Mount All Manifolds Reciprocating Arm Rod Mount To mount the gun on a stationary support (refer to FIG. 4. and Mounting Hole Layout, page 28): Manifolds 241161 and 241162 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. 3. Use the 1/8 in. alignment pin (P) to assist in orienting the gun. 1. Attach the gun to the support with two M5 x 0.
Setup Setup Air Line and Accessory Recommendations Fluid Line and Accessory Recommendations 1. Install an air pressure regulator on the gun cylinder air supply line. A minimum of 70 psi (0.49 MPa, 4.9 bar) air pressure must be supplied to the cylinder for proper operation. Air pressure opens the valve, a spring closes the valve. A three-way air valve, which exhausts cylinder air, is required. 2. Install a bleed-type air shutoff valve on the main air line.
Setup Manifolds 288219 and 288220 Manifold 244930 6. In a circulating system, connect an electrically conductive fluid hose to the gun fluid outlet (G). 7. This manifold is equipped with passages for circulating water to maintain the temperature of the gun. Ports provided are: In a non-circulating system, remove the gun fluid outlet fitting (G) and plug the outlet port with the pipe plug (109) supplied. KEY C Cylinder Air Inlet: accepts 1/4 in. (6.3 mm) O.D.
Setup Flush Spray Gun Adjust Spray Pattern Before running any paint through the spray gun: 1. To adjust the spray pattern direction with fan tips, orient the slot in the tip horizontally for a horizontal pattern and vertically for a vertical pattern. See Fig. 7. 1. Flush the gun with a solvent that is compatible with the fluid to be sprayed, using the lowest possible fluid pressure and grounded metal container. Install Spray Tip 2. Start the pump.
Operation Operation Pressure Relief Procedure Apply the Fluid 1. Shut off the power to the pump. Adjust the system control device, if it is automatic, so the gun starts spraying just before meeting the workpiece and stops as soon as the workpiece has passed. Keep the gun a consistent distance, 8 to 10 in. (200 to 250 mm), from the surface of the object being sprayed. 2. Turn off the air and fluid supply to the gun. To achieve best results when applying fluid: 3.
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. TI8100a 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 11. • 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. Daily Cleaning Procedure CAUTION This gun is not adjustable. To ensure proper shutoff, screw the piston cap (18) onto the housing (1) until it bottoms out.
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 16. General Troubleshooting Problem Cause Solution Fluid leakage through venting holes. Worn o-rings or packings on needle assembly (12). Replace o-rings or needle assembly. Air leakage through venting hole. Worn o-ring (23). Check and replace as needed.
Troubleshooting Problem Fluid needle will not trigger Fluid does not shut off. 311053C Cause Solution Loose or missing fluid needle stop (17) or setscrew (16). Replace stop (17) or tighten setscrew (16). Broken fluid needle (12). Replace fluid needle (12). Air leaking around piston (21). Replace o-ring (22) or piston assembly (21). Swollen piston o-ring (22). Replace o-ring (22). Do not immerse piston in solvent. Insufficient air pressure on the trigger.
Troubleshooting Spray Pattern Troubleshooting Problem Fluttering spray. Spitting spray. Cause Solution Insufficient fluid supply. Adjust fluid regulator or fill fluid supply tank. Air in paint supply line. Check, tighten siphon hose connections, bleed air from paint line. Worn seat (10, 41) or needle (12) ball. Inspect seat and needle for wear. Replace if necessary. The gasket (11) must be replaced whenever you remove the seat from the gun. Clean. Dirty spray tip (9). Irregular pattern.
Service Service 9. Remove the piston. Using a pliers, pull the piston (21) out of the piston housing (1). 10. If necessary, unscrew the two screws (15) holding the fluid housing (2) to the piston housing (1). If worn, remove the gasket (13) from the bottom of the piston housing. Follow the Service Notes in Figs. 8 and 9 when reassembling the gun. Gun repair kits are available. See page 18.
