Hydraulic accumulators don't get much attention until something goes wrong. A pressure spike damages a valve, a pump works harder than it should, or a breaker loses its punch mid-shift. These problems often trace back to one overlooked detail: the pre-charge pressure inside the accumulator. Testing it correctly takes less time than most people assume, and the payoff in avoided repairs and consistent performance is substantial. What follows covers the full process—tools, safety steps, readings, and what to do when the numbers don't look right.
