Hello, I just started working at a tool and die shop and we got a vtc 20, and every so often we get a error that says" slideway oil constant". When this occurs I goto the back of the machine and manually pump the oil. I also noticed that oil is dripping from the exhuast fans on the machine. I was wondering if anyone has a clue about the slideway oil error and if the oil in the exhaust fan area could also be the culprit?
