Before doing any work on a hydraulic system equipped with accumulators, you should __________.

Correct Answer: Option B — bleed off all stored energy from the accumulators

Accumulators store hydraulic energy under high pressure, even when the pump is secured. Before performing maintenance, the system must be depressurized by bleeding off the stored energy. Failure to do so can result in accidental release of high-pressure fluid, causing severe injury or damage to equipment.
