Pressure Relief Procedure
Follow the Pressure Relief Procedure whenever
you see this symbol.
This equipment stays pressurized until pressure is
manually relieved. To help prevent serious injury from
pressurized fluid, such as skin injection, splashing
fluid and moving parts, follow the Pressure Relief Pro-
cedure when you stop spraying and before cleaning,
checking, or servicing the equipment.
1. Engage trigger lock.
2. Close the bleed-type master air valve.
3. Disengage the trigger lock.
4. Hold a metal part of the gun firmly to a grounded metal
pail. Trigger the gun to relieve pressure.
5. Engage the trigger lock.
6. Open all fluid drain valves in the system, having a
waste container ready to catch drainage. Leave drain
valve(s) open until you are ready to spray again.
7. If you suspect the spray tip or hose is clogged or that
pressure has not been fully relieved:
a. VERY SLOWLY loosen tip guard retaining nut or
hose end coupling to relieve pressure gradually.
b. Loosen nut or coupling completely.
c. Clear hose or tip obstruction.
