While starting a hydraulic anchor windlass, you observe that hydraulic pressure does not develop in spite of the proper operation of the electric drive motor. Which of the following actions should you take FIRST to restore pressure?

Correct Answer: Option D — Make certain that the hydraulic reservoir is filled to the proper level.

Hydraulic systems require a positive suction head to prevent pump cavitation and ensure proper priming. If the reservoir level is low, the pump will draw air, preventing the development of system pressure. Always verify fluid levels before troubleshooting electrical components or mechanical linkages in hydraulic power units.
