Setup
Pressure Relief
Follow the Pressure Relief Procedure whenever
you see this symbol.
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
Pressure Relief Valves
NOTE:
A pressure relief valve can be purchased from
Graco. See Parts, page 71.
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.

NOTICE
Do not attach unsupported equipment to auxiliary
fittings such as fill ports and pump element. Attach-
ing 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
IG
. 14 for an
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).
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 unin-
tended 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 66.
•
Install a pressure relief valve close to every pump
outlet; before any auxiliary fitting.
