Nice writeup about maintenance routine, Maintenance is indeed a neccessity in the field of engineering especially in a workshop, All machines should have a planned maintenance routine in its design specifications so as to allow such equipment to have and extended useful life rather than total life. It is generally known that corrosion is a deteriorating factor that render the useful life of a machine low and also proper maintenance routine helps to reduce corrosion rate. nice one, from a big Fan .👍
