An asterisk behind a reference number in the parts list, for example (21*), indicates that the part is included in the repair kit. Clean all parts as you disassemble them and inspect them for wear or damage. Use Loctiter TL­242 thread sealant, or the equivalent, when thread sealant is specified. WARNING SKIN INJECTION HAZARD The system pressure must be manually relieved to prevent the system from starting or spraying accidentally. Fluid under high pressure can be injected through the skin and cause serious injury. To reduce the risk of an injury from injection, splashing fluid, or moving parts, follow the Pressure Relief Procedure whenever you: D D D D are instructed to relieve the pressure, stop spraying, check or service any of the system equipment, or install or clean the spray tip. Disassembly (Refer to Fig. 3) NOTE: Use all the replacement parts that are in the repair kit. 1. Close the supply line shutoff valve, and then the return line shutoff valve. Hold a metal part of the gun firmly to the side of a grounded metal pail, and trigger the gun to relieve pressure. Stop the pump at the bottom of its stroke. Open the drain valve (required in your system), having a container ready to catch the drainage. Leave the drain valve open until you are ready to spray again. If you suspect that the spray tip or hose is completely clogged, or that pressure has not been fully relieved after following the steps above, very slowly loosen the tip guard retaining nut or hose end coupling and relieve pressure gradually, then loosen completely. Flush the displacement pump if possible. WARNING To reduce the risk of serious injury whenever you are instructed to relieve pressure, always follow the Pressure Relief Procedure on page 7. Relieve the pressure. NOTICE Avoid getting dust or dirt in the motor during service. Cleanliness is essential when repairing an hydraulic motor. Disconnect the hydraulic hoses and plug all hydraulic connections and lines to prevent contamination. 308048 7 Service Disassembly (continued ­ refer to Fig. 3) NOTICE When removing the displacement pump, hold it securely. The pump is heavy and could fall off the motor. Disconnect the displacement pump from the motor, as explained in your separate pump manual. Pull the trip rod and piston from the lower housing (25) and cylinder (29).
