Pressure Relief Procedure
Follow the Pressure Relief Procedure whenever
you see this symbol.
Disconnect and isolate all power supplies.
Relieve pressure in the system using two wrenches
working in opposite directions on the pump element
and pump element fitting to slowly loosen fitting only
until the fitting is loose and no lubricant or air is leaking
from fitting.
NOTE: When loosening the pump element fitting, do
not loosen the pump element. Loosening the pump ele-
ment changes the output volume.
Connect to Auxiliary Fittings
• Always use two wrenches working in opposite
directions when connecting anything to pump ele-
ment or auxiliary fittings. See FIG. 17 for an exam-
ple.
• Torque pump element fittings to 50 in-lb (5.6 N•m).
• Torque pump element to 65 in-lb (7.3 N•m) when
connecting to the housing.
Pressure Relief Valves
NOTE: A pressure relief valve may be purchased from
Graco. See Pressure Relief Valves, page 18.
Pressure Relief Valves
This equipment stays pressurized until pressure is
manually relieved. To help prevent serious injury
from pressurized fluid, such as skin injection, splash-
ing fluid and moving parts, follow the Pressure Relief
Procedure when you stop dispensing and before
cleaning, checking, or servicing the equipment.
FIG. 17
NOTICE
Do not attach unsupported equipment to auxiliary fit-
tings such as fill ports and pump element. Attaching
unsupported equipment to these fittings can result in
irreparable housing damage.
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 each pump outlet to allevi-
ate unintended pressure rises in the system and pro-
tect the pump from damage.
• Only use a pressure relief valve that is rated for
no more than the working pressure of any com-
ponent installed in the system.
• Install a pressure relief valve before any auxiliary
fitting.

Set Pump Outlet Volume
1. Follow the Pressure Relief Procedure, page 18.
2. Use a wrench and turn the pump element counter-
clockwise to remove the entire pump element.
3. Replace the current spacer with the desired spacer.
NOTE: A spacer is required for operation. Only one
Graco spacer can be used at a time. The pumps from
the factory have a spacer (25N814) installed on the
pump element. Pump Element Kits (page 37) come
with a spacer. The spacer may be replaced depending
upon the required output volume.
4. Re-install the pump element into the pump base,
ensuring that the first thread of the element
engages correctly.
NOTE: It may be necessary to repeat the pump outlet
volume setup procedure after the pump is operating to
adjust the volume of the dispensed fluids.
5. Use a wrench and tighten the pump element fitting.
Torque to 50 in-lb (5.6 N•m).
NOTE:
• The dispensed volume amount varies depending
upon external conditions, such as lubricant
temperature and back pressure from downstream
connections.
• Use the volume adjustment process in conjunction
with setting the ON time of the pump to control the
output volume.
• The volume adjustment process should be used as
a starting point for dispensing the desired
lubrication volume.
Fill Reservoir - Grease Dispense
Pumps
To ensure optimal performance from the pump:
• Use only NLGI #000 - #2 greases appropriate for
the application, automatic dispensing, and the
equipment’s operating temperature. Consult with
the machine and lubrication manufacturers for
details.
• Fill the reservoir using a hand operated pump,
pneumatic pump or electric transfer pump.
• Do not overfill.
• Do not operate the pump without having a reservoir
attached.
