Oil maintenance and oil change
(A) Oil maintenance: drain water and dirt once a year using the drain plug. A small amount is
sufficient for this. Then carefully close the screw again.
(B) oil change:
Oil change after 1000 operating hours, as well as change of return filter.
If the oil gets cloudy, the oil and filter change is to be done immediately.
The most important steps:
1. Allow the oil to flow through the drain plug into a vessel. Wait until no more oil flows,
then close the drain plug again.
2. Disconnect the suction lines and pressure lines at the pumps and remove the double
pump so that the pumps can be vented. If necessary, store the ends of the pressure lines
high, so that oil does not escape unnecessarily.
3. Filling both pump housing in horizontal location at the highest leakage oil connection
so that no air cushion at the upper bearing is possible
