Pressure Relief
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.
Relieve pressure in system using two wrenches
working in opposite directions on pump element and
pump element fitting to slowly loosen fitting only until
fitting is loose and no more lubricant or air is leaking
from fitting.
NOTE: When loosening pump element fitting, do NOT
loosen pump element. Loosening pump element will
change the output volume.
Connecting to Auxiliary Fittings
NOTICE
Do not attach unsupported equipment to auxiliary fittings such as fill ports and pump element. Attaching
unsupported equipment to these fitting can result in
irreparable housing damage.
•Always use two wrenches working in opposite
directions when connecting anything to pump element or auxiliary fittings. See F
ple.
•Torque pump element fittings to 50 in. lbs (5.6
N•m).
•When connecting pump element into housing
torque to 50 in. lbs (5.6 N•m).
Pressure Relief Valves
To prevent over-pressurization, which can result in
equipment rupture and serious injury, a pressure
relief valve appropriate for the lubrication system
must be installed close to every pump outlet to alleviate unintended pressure rises in the system and protect the G3 pump from damage.
IG. 20 for an exam-
•Only use a pressure relief valve that is rated for
no more than the working pressure of any component installed in the system. See Technical
Data, page 81.
•Install a pressure relief valve close to every pump
outlet; before any auxiliary fitting.
NOTE: A pressure relief valve can be purchased from
Graco. See Parts, page 83.

Loading Grease
To ensure optimal performance from the G3:
•Only use NLGI #000 - #2 greases appropriate for

•Do not overfill.
•Do not operate G3 without reservoir attached.
NOTICE
Care must be used when filling the reservoir using a
pneumatic or electric transfer pump to not pressurize and break the reservoir.
Changing Greases
When changing greases, always use compatible fluids
or greases.
The Auto-Fill Shut Off is used for refilling the G3 reservoir in an automatic lubrication system. As fluid is added
to the reservoir, it pushes the plate valve up to the top of
the reservoir. The plate valve then pushes the valve pin
and closes the inlet fluid path.
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 system, be sure you know the maximum working pressure of each component. Never exceed the
maximum working pressure of the lowest rated component in the system. Over-pressurizing any component 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.
Remote Fill with Remote Fill Manifold
The reference letters used in the following instructions
refer to the Typical Installation diagram, page 11.
The fill valve is used to relieve pressure in the refill line
and to reset the Auto Fill Shut Off. See Fill Valve instruction manual 333393. Graco fill valve, part no. 77X542 is
available. Contact your local Graco distributor.
When the fluid refilling path closes, the refilling line pressurizes and brings the refilling pump to a pressurized
stall condition.
NOTE: The operator must monitor system while filling
the reservoir to prevent overfilling.
The remote filling station pump stalls (dead-heads)
when the reservoir is full, causing the supply system
pressure to rise to the maximum output pressure
of the filling station pump. To help prevent equipment
damage or serious injury caused by pressurized fluid,
such as skin injection or injury from splashing fluid,
always use a remote filling station pump with a maximum output pressure of 5100 psi (35.1 MPa,
351.6 bar) and use supply hoses with a minimum
pressure rating of 5100 psi (35.1 MPa, 351.6 bar).
1. Pull out and hold the Pressure Relief Knob (T) long
enough to relieve line pressure between Fill Manifold (N) and Auto-Fill Shut Off Valve (B).

The reference letters used in the following instructions
refer to the Typical Installation diagram, page 12.
1. A supply hose pressure relief valve (Y) and overflow
container (W) (for collecting excess fluid that drains
during pressure relief) must be installed in an easily
