ABSTRACT:
The present invention is directed to lubrication system having a reservoir having a body. A follower is moveably disposed in the body. The system further comprises an alarm system having an electrical switch operably associated with the follower. The alarm generates a signal when the follower is at a predetermined location in the body. The alarm system may generate a signal when the follower is at a lower location in the body such as when the reservoir has an amount of lubricant representing a predetermined amount of usage time remaining. The alarm system may also generate a signal when the follower is at an upper location in the body such as when the reservoir is filled with lubricant wherein the signal acts to automatically interrupt the fill of lubricant.
