This document discusses equipment maintenance and total productive maintenance (TPM). It outlines the aims of equipment maintenance as keeping equipment ready for productive operation and defines failure as when equipment loses its prescribed function. It then lists common symptoms of failure-prone workplaces and ways to prevent failures through conducting preventive maintenance like routine cleaning, lubrication, and inspection. The document also discusses implementing preventive maintenance to minimize erratic failure intervals, extend equipment life, and predict failures. Finally, it introduces TPM, explaining that as machines become more advanced, products are made by equipment so failures cannot be allowed, and all departments must work together to properly maintain equipment through TPM's 12 step deployment program.
