Technician a says on a correctly operating gas accumulator, precharge pressure should be checked during a 500-hour preventative maintenance inspection. technician b says it is safe to perform repairs on a hydraulic system if the system contains an accumulator that is charged full of oil. who is correct?

Tech A

Explanation:

A gas accumulator stores fluid under pressure. This pressure is potential energy as it can be turned into work and can serve various functions in a hydraulic system. These accumulators can have a specific amount of fluid under pressure and store it, the fluid is released when a specific task needs to be performed.

While maintaining these accumulators is simple and not too much work, it is important that some safety measures are taken to protect the handler and to protect the accumulator from contamination. From this we can state that when servicing a properly functioning gas accumulator, the preload pressure must be checked during a 500 hour preventive maintenance inspection.
