Air in Hydraulic system

[bentley2010]

I have 1986 Kioti LB2204 that I just got in January and have no manuals for it. The tractor got low on hydraulic fluid and the 3 point hitch stopped working, so I put a gallon of fluid in it and now the 3 point hitch will raise occationally when I first start it. I am worried I am going to take the pump out due to cavitation, How am I suppose to get the air out of the system, and the hydraulic filter is upside down so I cant even fill that to try to help

Where does it read for level on the dipstick, *assuming there is one on your model? (*I'm not sure, about your model and what it has or doesn't).

No dipstick, just a big plug marked oil the screws into a hole on top of the transmission
