Filling Grease Reservoirs
OVER PRESSURIZATION HAZARD
Over pressurization can result in equipment rupture
and serious injury. Fill slowly to avoid over pressuriz-
ing the reservoir.

•
Filling grease reservoirs requires an external,
air-free supply source be connected to the fill stud
(13).
•
To avoid introducing air into the system, make sure
there is enough grease in the supply source to fill
the reservoir without being disconnected.
•
Operate the supply source at a steady speed to
allow air-free filling of the reservoir. Filling the reser-
voir too fast may result in air pockets.
•
The level of grease is checked by visual means.
- In reservoirs with plastic cylinders, the grease level
can be viewed through the cylinder.

1. Remove cover (12)
2. Connect grease supply source to fill stud (13).
3. Loosen the drain plug (E) (located on the opposite
side of the base from the fill stud (13) (F

4. Slowly begin to fill the reservoir, allowing air trapped
under follower to exhaust out the open drain plug.
5. When grease free of air flows from the drain, tighten
the plug (E) and continue to fill the reservoir until fol-
lower is at the vent hole in reservoir tube (any
remaining air and small amount of grease will exit
drain).
6. When filling is complete, turn off the supply source
and disconnect if from the fill stud (13). Replace the
cover (12).
NOTE: A check valve in the fill stud will prevent
lubricant from being forced back out.
7. Loosen system mainline connection at pump outlet.
8. Operate pump until lubricant free of air flows from
outlet port.
9. Tighten mainline connection at pump. Pump is now
free of air.
NOTE: If the pump will not take a prime, it may be
helpful to inject several ounces of heavy oil through
the fill stud. The pump will then prime on oil pulling
the grease behind it. If it becomes necessary to use
this method, all injected oil should be discharged at
the loosened system mainline connection along with
any air.
