tion until you are ready to spray again.
6. If you suspect the spray tip or hose is clogged or that
pressure has not been fully relieved:
a. VERY SLOWLY loosen the tip guard retaining
nut or the hose end coupling to relieve pressure
gradually.
b. Loosen the nut or coupling completely.
c. Clear hose or tip obstruction.
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.
