Hydraulic oil level low

[hobbes]

Noticed the hydraulic oil level on one of our 36's was very low, 3/4 down the baffle, not sure how long it's been running like that. Using Mobil tri-synthetic. As far as I know this would not have caused any damage to hydraulics. Am I right?

probably no damage,i it was to low,the machine would have sucked some air,and you would have heard the pumps moan,and temporarily slow down.By running it low,you do increase the temperature that fliud runs at and increase the likelyhood of foaming the oil,and air in the fliud,both which arent the best thing for hydro systems.I would check ofr leaks,sounds like you have one,or someone put it on its side/back and oil ran out.
