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.
