(2) Fill reservoir (14) by pumping handle (6) until piston (15) appears in normal operating range of indicator (16). Check cylinder for leakage. (3) Verify indicator (16) reading. e. If indicator (13) or (16) exceeds normal operat- ing range: NOTE This task forces excess fluid into fluid service unit. (1) For indicator (13), apply primary hydraulic power (para 1.72). For indicator (16), apply utility hydraulic power (para 1.73). (2) Apply external power – air (para 1.71). (3) Pressurize air system (TM 1-1520-238-T).
