Hi..we have a Fadini Combi 740 gate setup with a hydraulic mechanism. They have been in for 22 years. One side is now short of oil and I have tightened the nut causing the leak problem so it’s now dry. I can’t find anywhere how much hydraulic oil to put in the reservoir and at £60 for 2 litres I don’t want to overbuy. There doesn’t appear to be a mark in the reservoir itself and there is nothing in the documentation- any ideas ? Thanks in advance.
