What are the three types of PMCS that must be performed daily?

• A. Before PMCS, During PMCS, and After PMCS
• B. Before PMCS only
• C. During PMCS only
• D. After PMCS only

Answer: (A)

PMCS stands for Preventive Maintenance Checks and Services and is done daily to keep equipment ready and safe. The complete set consists of three phases: before operation, during operation, and after operation. Doing all three ensures you catch issues at the right time—before use to prevent starting with a fault, during use to catch problems that develop while operating, and after use to verify condition, address any problems found, and prepare the equipment for storage or the next operator. If you only perform one phase, you risk missing a fault that’s only visible before or after use, or one that develops during operation, which can lead to breakdowns or unsafe conditions.
