Figure 8-5
For the standard temperature range from 0 °C to +60 °C, the backstops are filled with
Klüber-Summit HYSYN FG68.
In the case of ambient temperatures of less than -20 °C and greater than +60 °C, please
contact Technical Support.
The backstop can also be filled with the oil used in the gearbox.

Service life of the lubricants

Note
In case of ambient conditions deviating from normal conditions, e.g. high ambient
temperatures, high relative humidity, aggressive ambient media, the intervals between
changes should be shorter. In such cases please contact Technical Support for assistance in
determining the individual lubricant change intervals.
Note
Oil sump temperatures above +80 °C can reduce service life. In this context, the rule is that
increasing the temperature by 10 K will approximately halve the service life, as illustrated in
the figure titled "Guide values for oil change intervals".
