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
Procedure when you stop dispensing and before
cleaning, checking, or servicing the equipment.
Do not lift pressurized equipment.
To relieve pressure in the system, use two wrenches
working in opposite directions on the pump outlet
fitting to slowly loosen the fitting only until no more
lubricant or air is leading from the fitting (F

COMPONENT RUPTURE HAZARD
The maximum working pressure of each component
in the system may not be the same. To reduce the
risk of over-pressurizing any component in the sys-
tem, be sure you know the maximum working pres-
sure of each component. Never exceed the
maximum working pressure of the lowest rated com-
ponent in the system. Over-pressurizing any compo-
nent can result in rupture, fire, explosion, property
damage and serious injury.
Regulate input pressure to the remote fill pump so
that no fluid line, component or accessory is over
pressurized.
