Preventive maintenance routines __________.

• A. Are created randomly
• B. Are formulated from manufacturing recommendations
• C. Are determined by production schedule
• D. Focus only on new equipment

Answer: (B)

Preventive maintenance routines are formulated from manufacturing recommendations. The manufacturer provides guidance based on how the equipment was designed, tested, and expected to wear, detailing what needs to be serviced, how often, and with which lubricants, parts, or torque specifications. Following these recommendations keeps the equipment operating as intended, supports reliability and safety, and often aligns with warranty requirements. Creating maintenance plans randomly would miss critical wear points and appropriate intervals. Relying only on the production schedule might time work correctly, but it doesn’t establish the content or frequency of the maintenance itself. And focusing solely on new equipment ignores the ongoing needs of older assets, where wear and degradation require established routines that adapt over time.
