4.6 Useable reservoir volume
The useable reservoir volume mainly depends on the NGLI consistency class and the operating temperature of the lubricant to be used.
In case of high consistency and low operating temperature normally more lubricant sticks to the inner surfaces of the reservoir/ pump and is thus no more
available for being dispensed.

To prime an empty pump up to the MAX marking of the reservoir, the following lubricant quantities are required.
Reservoir size
Quantity
When using lubricants of a relatively low consistency in pumps subjected to srong vibrations or tilting
motions (e.g. construction and agricultural machinery), make sure to maintain a level that is about
25 mm below the MAX marking of the reservoir. This prevents lubricant from entering the reservoir
vent. In case of very strong vibrations this value must be increased, for low vibrations it can be reduced.
Changing the filling level by 10 mm corresponds to a volume change of about 0.2 litres.
