Setup
Setting Pump Outlet Volume
NOTE:
•Before making any adjustments to pump volume, Relieve Pressure following procedure on page 23.
•Only use Graco supplied spacers to control output volume.
•It may be necessary to repeat this outlet volume setup procedure after the pump is operating to
1.Use a wrench to turn pump element
2.If needed, remove or insert spacers to achieve required pump output volume. A tool may be needed to facilitate removal.
Pump volume control is set using either no (0) spac- ers, 1 or 2 spacers (FIG. 15).
Do not use more than 2 spacers to adjust output vol- ume.

NOTE:
•The amount of dispensed volume can vary depend- ing on external conditions such as lubricant tem- perature and back pressure from downstream connections.
•Use of these volume adjustment in conjunction with setting the ON time of the pump will allow for control of the output volume.
•Use these volume adjustments as a starting point and adjust as necessary to ensure desired lubrica- tion dispense.
3.Tighten pump element fitting. Torque fitting to 50 in. lbs (5.6 N•m).
FIG. 15
Loading Grease
To ensure optimal performance from the G3:
•Only use NLGI #000 - #2 greases appropriate for your application, automatic dispensing, and the equipment’s operating temperature. Consult with machine and lube manufacturer for details.
•The reservoir can be filled using a hand operated pump, pneumatic pump or electric transfer pump.
•Do not overfill (FIG. 17).
•Do not operate G3 without reservoir attached.
NOTICE
•Always clean fitting (D) with a clean dry cloth prior to filling reservoir. Dirt and/or debris can damage pump and/or lubrication system.
•Care must be used when filling the reservoir using a pneumatic or electric transfer pump to not pressurize and break the reservoir.
