Pressure Relief

Follow the Pressure Relief Procedure when-
ever 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 work-
ing 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 fit-
ting.
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 fit-
tings 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 ele-
ment 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
A pressure relief valve appropriate for the lubrication
system must be installed close to the pump outlet to
alleviate unintended pressure rises in the system and
protect the G1 pump from damage.
• Only use a pressure relief valve that is rated for no
more than the working pressure of the G1 pump it
is installed on. See Technical Data, page 29.
• Install a pressure relief valve before any auxiliary
fitting.
