Pressurized fluid can penetrate body tissue and result in serious injury or
death. Leaks can be invisible. keep away from any suspected leak.
Relieve pressure in the hydraulic system before searching for leaks,
disconnecting hoses, or performing any other work on the system. If you
must pressurize the system to find a suspected leak, use an object such
as a piece of wood or cardboard rather than your hands. When loosening
a fitting where some residual pressure may exist, slowly loosen the fitting
until oil begins to leak. Wait for leaking to stop before disconnecting the
fitting. Fluid injected under the skin must be removed immediately by a
surgeon familiar with this type of injury.
