WARNING INJECTION HAZARD Spray from the gun, hose leaks, or ruptured components can inject fluid into your body and cause an extremely serious injury, including the need for amputation. Splashing fluid in the eyes or on the skin can also cause a serious injury. Fluid injected into the skin might look like just a cut, but it is a serious injury. Get immediate medical attention. Do not point the spray gun at anyone or at any part of the body. Do not put hand or fingers over the spray tip.
Installation Ventilate the Spray Booth Non–Circulating Setup Shown (cutaway view) WARNING TOXIC FLUID HAZARD To prevent hazardous concentrations of toxic and/or flammable vapors, spray only in a properly ventilated spray booth. Never operate the spray gun unless ventilation fans are operating.
Installation Mount the Gun Manifolds 241161 and 241162 To mount the gun on a reciprocating arm [0.5 in. (13 mm) diameter maximum], insert the bar (A) through the hole in the manifold as shown in Fig. 2. Secure the gun to the bar by tightening the mounting screw (B). The tip of the gun should be 8 to 10 in. (200 to 250 mm) from the surface of the object being sprayed. All Manifolds To mount the gun on a stationary support, see Fig. 3. Also refer to the mounting hole layout on page 30.
Installation Air 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.
Installation Manifolds 241161 and 241162 Manifold 244930 6. In a circulating system, connect an electrically conductive fluid hose to the gun fluid outlet (G). 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.
Installation Ground the System WARNING FIRE AND EXPLOSION HAZARD Improper grounding could cause static sparking, which could cause a fire or explosion. To reduce the risk of property damage or serious injury, follow the grounding instructions below. The following grounding instructions are minimum requirements for a system. Your system may include other equipment or objects which must be grounded. Check your local electrical code for detailed grounding instructions for your area and type of equipment.
Operation 5. Leave the drain valve(s) open until you are ready to spray again. Safety WARNING INJECTION HAZARD Remember, this is not an air spray gun. For your safety be sure to read and follow the Warnings on pages 2 and 3 and throughout the text of this instruction manual. 6.
Operation Adjust Spray Pattern Clean the Spray Gun and System Daily 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. 2. Start the pump. Adjust the fluid pressure until the spray is completely atomized. Use the lowest pressure necessary to get the desired results. Higher pressure may not improve the spray pattern and will cause premature tip wear and pump wear. 3.
Operation Flush the Gun Daily WARNING INJECTION HAZARD To reduce the risk of an injection injury, follow the Pressure Relief Procedure on page 9 before cleaning, removing, or installing a spray tip and whenever you are instructed to relieve pressure. WARNING To reduce the risk of serious injury, including splashing fluid in the eyes or on the skin, or static electric discharge when flushing: Be sure the entire system, including flushing pails, are properly grounded. Remove the spray tip.
Troubleshooting WARNING INJECTION HAZARD To reduce the risk of an injection injury, follow the Pressure Relief Procedure on page 9 before checking or servicing any of the system equipment and whenever you are instructed to relieve pressure. NOTE: 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, on page 13.
Troubleshooting WARNING INJECTION HAZARD To reduce the risk of an injection injury, follow the Pressure Relief Procedure on page 9 before checking or servicing any of the system equipment and whenever you are instructed to relieve pressure. General Troubleshooting (continued) Problem Cause Solution Fluid does not shut off. Piston cap (18) is not fully tightened. Tighten piston cap until it bottoms out. Spring (19) is not in place. Check that spring is in position. Swollen piston o-ring (22).
Service WARNING INJECTION HAZARD To reduce the risk of an injection injury, follow the Pressure Relief Procedure on page 9 before checking or servicing any of the system equipment and whenever you are instructed to relieve pressure. NOTE: Follow the Service Notes in Figs. 8 and 9 when reassembling the gun. Gun repair kits are available. See page 18. Reference numbers marked with an asterisk (13*) in the service procedures are included with the 241480 Air Seal Repair Kit.
