5-7 Accumulator/Reservoir Fluid and Nitrogen Drain Procedure
Warning: Accumulators, gas bottles, and associated hydraulic fluid systems are inherently dangerous due
to high pressure gasses and fluids. Do not attempt to operate these systems unless adequately trained,
experienced with the items and systems, and can recognize the potential risks involved if mishandled.
Failure to do so may result in severe injury or even death.
Warning: Always use dry inert gas (dry nitrogen – N
2
) in the Accumulator/Reservoir system. Never use
air or oxygen, due to the danger of combustion or explosion. In enclosed spaces, N
2
is an asphyxiant;
always insure adequate ventilation when working with nitrogen gas. If leaking gas is discovered, extra
care should be taken to avoid risk associated with ejection of fittings or hoses.
1) Close the shutoff ball valves located upstream of the accumulator and reservoir.
