Check Precharge Pressure
The precharge pressure of the accumulators is the pressure of the nitrogen gas with which the accumulators are initially
charged. This pressure must be checked before the system pressure is raised for the initial engine start. To check the
precharge pressure, proceed as follows:
1.
Ensure that all of the accumulator shutoff valves (1) are CLOSED and all of the accumulator gauge valves (2) are OPEN.
2.
OPEN the accumulator blowdown valve (3) on the starting system side of the ramp/steering hydraulic tank.
