TM 9–2350–311–20–2 e WARNING Do not drop tank of compressed nitrogen gas. Do not tap nitrogen tank. Tank can explode when tapped or dropped. When using in confined areas, use extreme care; gas could cause suffoca- tion. Make sure nitrogen cylinder contains dry nitrogen. Dry nitrogen tanks are marked with one or two black bands. Certain other gases can cause accumulator to explode, resulting in possible injury. Failure to close check valve on main accumulator and pressure regulator valve could result in injury from high pressure in hoses of nitrogen charging assembly and air pressure gage assem- bly. Failure to open safety-relief valve could result in injury from high pressure trapped in hoses of nitrogen charging assembly and air pressure gage assembly. Accumulator contains high pressure nitrogen. Use caution when handling and working with it. High pressure gas is used in charging the accumulators and fire control equipment. Do not ex- ceed recommended psi when charging these components. Keep face and body clear of release valves. Failure to observe safety precautions may result in injury or death.
