What is the correct sequence for performing a typical PMCS on a piece of equipment?

• A. Inspect, test, lubricate, adjust, clean; verify safety devices; document results and replace parts if needed.
• B. Clean, lubricate, document, test, inspect.
• C. Inspect, disassemble, tighten fasteners to maximum torque, repaint.
• D. Test, disassemble, lubricate, replace parts, and note only if failures occur.

Answer: (A)

PMCS is a structured, stepwise check to ensure equipment is ready and safe to use. Start with a thorough inspection to spot obvious defects or wear. Then test the functions to confirm that systems operate as intended. Next, lubricate moving parts to reduce friction and wear, followed by making any necessary adjustments to settings or alignments. Cleaning comes after these tasks to remove debris that could obscure problems and hinder inspection. After the mechanical checks, verify safety devices are functioning properly since this directly affects operator and equipment safety. Finally, document the results and replace parts as needed to address any issues found. This sequence emphasizes identifying issues first, validating operation, ensuring safety, and recording outcomes so the equipment can be kept in a ready state. The other options mix steps that don’t belong in PMCS, such as disassembly, repainting, or tightening to maximum torque, and they place tasks out of order or omit essential documentation and safety verification.
