The first oil change is required after 50 operating hours, further oil changes must be
performed annually. The intake filter of the pump distributor gears and the pressure fil-
ter cartridge must be replaced at every oil change.
Proceed as follows for an oil and filter exchange:
– Clean the area around the intake and pressure filters before the oil change.
– Change oil only with gears warm after operation.
– Put an oil-resistant collecting vessel of sufficient size underneath.
– Unscrew the closing cap at the oil drain valve (3).
– Screw on the provided oil drain hose. The valve opens and the old oil drains.

– Remove the screw cap (4) of the intake hose from the filter connection. For this
purpose, you need a fork spanner SW 36.
– Loosen the hexagonal bolt connection (5) on the filter flange. The bolt connection
must only be loosened. In no case totally screw off this bolt connection. For this
purpose, you need a fork spanner SW 46.
– Screw out the 4 bolts (SW13) on the filter flange (6) and pull out the filter insert.
– Exchange the filter element for a new one (ROPA item no. O-40320010). When
installing, always use a new paper gasket (ROPA item no. O-20350003) and new
O-ring (ROPA item no. 412595). Before assembly, coat them with some oil.
– Retighten the flange (6) and hose line (5/4).
