I had to do a screen capture as it is all in PDF.

My DK35se manual only shows the orange fill port by the IP.. I did not even know about the one on the valve cover. I will check for it next time I have the hood up. One thing I have learned in Kioti manuals: There is a lot of erroneous and conflicting information in the manual.

I have the Service Manual and Workshop Manual for the CK 30
It specifically shows the Oil Inlet on top of the Rocker cover. If oil is low, add oil and an arrow pointing to the rocker/tappet cover cap. No mention of filling it anywhere else in my book. Thats where I fill mine.
I finally looked at my owners manual and service manual today, and both tell me to add oil in the rocker cover, as shown in the diagram above from Alien. ...
I'd bet more recent manuals say to fill the oil using the red cap on the side.
