🔍 Key Concepts
• Hydraulic anchor windlass operation – what happens inside the hydraulic motor and lines when it is actually run
• Difference between preventive maintenance checks (levels, filters, strainers, testing fluid) and exercising the machinery
• Why moving parts in hydraulic systems need circulation of oil to lubricate internal components
💭 Think About
• Which option will actually cause hydraulic oil to move through the motor, valves, and lines, coating internal parts with oil?
• Which choices are inspections or tests only, and do not move or exercise the machinery itself?
• If the unit has been idle, what specific action will verify it still operates while also spreading lubricant internally?
✅ Before You Answer
• Identify which choice involves running the windlass, not just looking at or testing the fluid or components
• Eliminate any answers that are only visual checks or lab tests with no motion of internal parts
• Ask: which maintenance action would your chief mate want done on all deck machinery that sits idle, to keep seals, bearings, and internal surfaces lubricated?
