This equipment stays pressurized until pressure is
manually relieved. To help prevent serious injury
from pressurized fluid, such as skin injection, splash-
ing fluid and moving parts, follow the Pressure Relief
Procedure when you stop spraying and before clean-
ing, checking, or servicing the equipment.
1. Set both (2) pump valves to OFF. Turn engine OFF.
2. Turn pressure control to lowest setting. Trigger all
guns to relieve pressure.

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 the coupling completely.
c. Clear the obstruction in the hose or tip.
