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 spraying 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
example.
• 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
IG. 12 for an
FIG. 12
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.
• Only use a pressure relief valve that is rated for no
more than the working pressure of the G3 pump it
is installed on. See Technical Data, page 27.
• 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 30.

NOTE: It is not necessary to prime pump every time
pump is filled with lubricant.
Pump only requires priming the first time it is used or if it
is allowed to run dry.
1. Loosen pump element fitting (F
NOTE: When loosening pump element fitting, do NOT
loosen pump element. Loosening pump element will
change the output volume

No Controller Operation
The G3 Pump can be controlled using an external, user
supplied, power source and controller.
Refer to the Typical Installation diagrams provided on
page 8 for correct location of the required pump ground
wire and fuses.
NOTE:
• When using an external power source and controller, Pump ON (Run) Time should be set for no longer than 30 minutes.
• In most cases, Pump OFF (Rest) Time should be
twice as long as Pump ON (Run) time. If alternative
ON / OFF times are required, contact Graco Customer Service for assistance.
Low Level Output Option
Some G3 pumps without controllers include a Low Level
Output Option. It can be configured with an M12 connector in code location “G” or with a DIN connector in
code location “K”. (See Understanding the Model Number, page 4.)The low level signal is monitored across
PINS 3 and 4. For PIN 3 and 4 locations and wiring
information the Low Level Outputs diagram, page 15.
NOTE: A low level warning is triggered when the controller detects PINS 3 and 4 have momentarily closed.
Grease Pumps
When the grease level has reached a low warning level,
PINS 3 and 4 momentarily close (1 time per paddle revolution) sending the signal that the fluid has reached a
low level to the controller.
To ensure that a low level condition has been met, 3 or
more low level triggers must be detected within 1 minute
or less.
See F
IG. 20 for an illustration of a typical Low Level Out-
put response to low grease level.

Oil Pumps
When the oil level has reached a low warning level,
PINS 3 and 4 close, sending the signal to the controller
that the fluid has reached a low level.
Typical Low Level Output Response with Low Level Fluid in Oil Models
To ensure that a low level condition has been met, the
low level trigger must be detected for 10 continuous seconds.

The pressure relief valve uses a
pressure adjustment screw (a) to
set the pressure release point. It
is not intended as a way to
relieve pressure during normal
operation, but as a protective
measure in the event there is an
unintended pressure increase in
the system. Do not use this pressure relief valve a means of
relieving pressure in day-to-day,
normal cycle operation.
The pressure adjustment screw
will require periodic adjustments.
Whenever the valve is set/adjusted (after the set point is
found) it is important to ensure that the valve is not bottomed out and there is at least 1/2 turn of adjustment
remaining. This is determined by turning the screw (a)
1/2 turn and then back turning it out again.

Graco Standard Warranty
Graco warrants all equipment referenced in this document which is manufactured by Graco and bearing its name to be free from defects in
material and workmanship on the date of sale to the original purchaser for use. With the exception of any special, extended, or limited warranty
published by Graco, Graco will, for a period of twelve months from the date of sale, repair or replace any part of the equipment determined by
Graco to be defective. This warranty applies only when the equipment is installed, operated and maintained in accordance with Graco’s written
recommendations.
This warranty does not cover, and Graco shall not be liable for general wear and tear, or any malfunction, damage or wear caused by faulty
installation, misapplication, abrasion, corrosion, inadequate or improper maintenance, negligence, accident, tampering, or substitution of
non-Graco component parts. Nor shall Graco be liable for malfunction, damage or wear caused by the incompatibility of Graco equipment with
structures, accessories, equipment or materials not supplied by Graco, or the improper design, manufacture, installation, operation or
maintenance of structures, accessories, equipment or materials not supplied by Graco.
This warranty is conditioned upon the prepaid return of the equipment claimed to be defective to an authorized Graco distributor for verification of
the claimed defect. If the claimed defect is verified, Graco will repair or replace free of charge any defective parts. The equipment will be returned
to the original purchaser transportation prepaid. If inspection of the equipment does not disclose any defect in material or workmanship, repairs
will be made at a reasonable charge, which charges may include the costs of parts, labor, and transportation.
THIS WARRANTY IS EXCLUSIVE, AND IS IN LIEU OF ANY OTHER WARRANTIES, EXPRESS OR IMPLIED, INCLUDING BUT NOT
LIMITED TO WARRANTY OF MERCHANTABILITY OR WARRANTY OF FITNESS FOR A PARTICULAR PURPOSE.
Graco’s sole obligation and buyer’s sole remedy for any breach of warranty shall be as set forth above. The buyer agrees that no other remedy
(including, but not limited to, incidental or consequential damages for lost profits, lost sales, injury to person or property, or any other incidental or
consequential loss) shall be available. Any action for breach of warranty must be brought within two (2) years of the date of sale.
GRACO MAKES NO WARRANTY, AND DISCLAIMS ALL IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A
PARTICULAR PURPOSE, IN CONNECTION WITH ACCESSORIES, EQUIPMENT, MATERIALS OR COMPONENTS SOLD BUT NOT
MANUFACTURED BY GRACO. These items sold, but not manufactured by Graco (such as electric motors, switches, hose, etc.), are subject to
the warranty, if any, of their manufacturer. Graco will provide purchaser with reasonable assistance in making any claim for breach of these
warranties.
In no event will Graco be liable for indirect, incidental, special or consequential damages resulting from Graco supplying equipment hereunder, or
the furnishing, performance, or use of any products or other goods sold hereto, whether due to a breach of contract, breach of warranty, the
negligence of Graco, or otherwise.
