8.7.7 Taking oil samples
The oil sample from the superstructure hydraulic system is taken in a way
similar to that for the carrier hydraulic system.
Information on taking samples with the hose and for the laboratory analy-
sis; Ã Taking oil samples, p. 7 - 94.
Prerequisites – The engine must not be running and must be secured against unauthor-
ised use; Ã p. 2 - 3.
Selecting the
sampling location
To determine the usability of the oil, you must take a sample from the
hydraulic system. To do that you must connect the hose with the connecting
piece to a gauge port.
There is a gauge port (1) on the pump (2).
If the pump is running, then oil can be
removed at the gauge port.
