Setting Pump Outlet Volume
NOTE:
•
Before making any adjustments to pump volume,
Relieve Pressure
following procedure on page 18.
•
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
re-adjust the volume of dispensed fluids.
1.
Use a wrench to turn pump element counter-clock-
wise to loosen. Do not remove entire pump element.
Only back pump element out enough to allow
spacer to be slid on or off (F
IG
. 18).
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 (F
IG
. 18).
Do not use more than 2 spacers to adjust output vol-
ume.
3.
Tighten pump element fitting. Torque fitting to 50 in.
lbs (5.6 N•m).
•
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.
Loading Grease
To ensure optimal performance from the G3:
•
Only use NLGI #000 - #2 greases appropriate for
your application, automatic dispensing, and the tem-
perature. Consult with machine and lube manufac-
turer for details.
•
The reservoir can be filled using a hand operated
pump, pneumatic pump or electric transfer pump.
•
Do not overfill.
•
Do not operate G3 without reservoir attached.

NOTICE
•
Always clean fitting (D) (F
IG
. 19) 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.
