Filling the grease reservoir
When the grease in the reservoir reaches its minimum level, the reservoir needs to be refilled. To
facilitate this, the pump unit is fitted with a grease nipple onto which a garage grease pump can
be placed.
To be able to fill the reservoir using a special filling pump, a special filler coupling can be installed.
Groeneveld
can supply you with both mobile or stationary, hand-operated or pneumatic filling
pumps.

Filling the reservoir with a garage grease pump
Filling procedure
The grease pump must be suitable for class 2 grease.
First fill the filling hose with grease (if the filling pump or grease barrel is new). This prevents air
being introduced in the grease reservoir.
1.
Remove the dust cap of the filler coupling.
2.
Clean the filler coupling and the coupling on the hose thoroughly.
3.
Lock the hose onto the filler coupling or position the grease gun onto the filler coupling.
4.
Fill the reservoir up to its maximum level, as indicated on the reservoir. Never fill the reservoir
any higher than the maximum level indicated, otherwise the follower piston may become
damaged.
5.
Remove the filling hose or grease gun.
6.
Clean the dust cap and the grease nipple or filling coupling with a clean rag. Place the dust
cap back onto the filler coupling.
NOTES
If the pumping action seems to go heavy, check the filter behind the grease nipple or filling
coupling on the pump unit. Clean the filter and the grease nipple or filler coupling. Also check the
filling hose for obstructions and clean it.
Any air that may be introduced beneath the follower piston will escape through an opening at the
top of the guide rod of the follower piston. These air inclusions, together with any excess grease,
will exit via the de-aerating opening at the side on the pump unit.
