Replace any excessively worn components with original parts and use the lubricants recommended by
the manufacturer.
Dispose of the worn-out components and lubricants in accordance with the relevant statutory require-
ments.

Table of lubricants
The pump is delivered complete with oil, with the characteristics stated on the data plate.
When topping up the oil, use an oil suitable for conditions in the operating environment (see recommenda-
tions provided in the annexes and see "Environmental operating limits").
The correct lubricating oil viscosity depends on the external temperature.
Use the graph to select the degree of viscosity best suited to the temperatures of use.
