remember grease after each use and oil change every 80 hrs. or once a year after the first 20hrs. break in period. hydro oil should be changed every 200hrs or every 2 years. at a minimum.
I would add that people may want to disconnect the two hoses for the swing bearing and then pump grease into the fittings until grease comes out of the disconnected hoses. I thought I was greasing mine thinking the hoses were already full but nope. I had to pump quite a lot of grease until it came out of the hoses.
I have the same one you have This is the first video I have seen foe a miva va15 mini Right now i have a problem if where my hydraulic is not working it wont walk the boom and bucket moves very slow
Great points on changing zerk fittings out. That was the 2nd thing I did as the 1st was 'attempting to grease mine. OK that was after I made a small hole in the ground lol
