1. 8587A The gun is supplied with an internal fluid filter 32 Install the filter in the gun port being used as the fluid inlet See Fig 1 NOTE The gun can operate without the filter If you are using highly viscous fluid and the filter causes an unacceptable pressure drop remove the filter Install the gun on the manifold using the four screws 17 Thread the screws by hand then torque alter nately and evenly to 65 in lb 7 3 Nem Models 233670 with Manifold 244930 This gun and manifold are designed to be used with high viscosity material and sealants such as protective coatings and automotive sealants There is no circula tion port The fluid inlet uses both ports to feed the valve and no filter is used 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 Attach 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 The tip of the g2. Fluid Line and Accessory Recommendations 44 WARNING INJECTION HAZARD To reduce the risk of property damage or serious injury including injection which could be caused by component rupture or unrelieved fluid pressure A fluid drain valve s is required in your system to assist in relieving fluid pressure in the dis placement pump hose and gun triggering the gun to relieve pressure may not be sufficient A fluid pressure regulator must be installed in the system if the pump s maximum working pressure exceeds the gun s maximum fluid working pressure see the front cover 1 Install a fluid filter and drain valve s close to the pump s fluid outlet 2 Install a fluid pressure regulator to control fluid pressure to the gun NOTE Some applications require fine tuned control of fluid pressure You can control fluid pressure more accurately with a fluid pressure regulator than by regulating the air pressure to the pump 3 Install a fluid shutoff valve to shut off the fluid supply to the gun 4 For paint spray applications install an in line fluid filter part no 210500 on the gun fluid inlet F to avoid clogging the spray tip with particles from the fluid See Fig 4 5 Connect the electrically conductive fluid hose to the gun fluid inlet F or optional in line filter Installation Manifolds 241161 and 241162 6 Ina circulating system connect an electrically conductive fluid hose to the gun fluid
3. Flush the pump and gun before the fluid can dry in it If itis available the flushing procedure provided in the pump or sprayer manual should be used instead of this procedure Relieve the pressure as instructed on page 9 Remove the spray tip Clean the parts Supply a compatible solvent to the gun fluid inlet Start the pump and operate it at its lowest pres sure Trigger the gun into a grounded metal waste container until all the material is removed from the gun passages Relieve the pressure as instructed on page 9 Disconnect the solvent supply 308813 11 Troubleshooting NOTE A WARNING INJECTION HAZARD To reduce the risk of an injection injury 0 follow the Pressure Relief Procedure on page 9 before checking or servicing Check all possible remedies in the troubleshooting charts before disassembling the gun Us Some improper patterns are caused by the improper balance between air and fluid Refer to any of the system equipment and whenever you are instructed to relieve pressure General Troubleshooting Problem Fluid leakage through venting holes Cause Worn o rings 31 or needle assembly 12 Spray Pattern Troubleshooting on page 13 Solution Replace o rings or needle assembly Air leakage through venting hole Worn o ring 23 Check and replace as needed Air leakage from back of gun Worn o rings 22 23 Replace o rings Fluid leakage
