Pressure Relief Procedure Before you start:
Be sure you have all necessary parts on hand. 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.

Open the drain valve (required in your system), having a container ready to catch the drainage. 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.
