Inspection at the machine is the right time to check not only oil level, but also things like temperature, sight and smell. Is the lubricant dark, discolored or foamy? These notes may be your first indication that something’s amiss.
It’s never just about that low level or water contamination. It’s always about many different factors acting together to lead to the current situation. Your issue is going to be closely related to multiple, ever-changing factors involving your process, your machine and your facility.
