Escaping fluid!
Hydraulic fluid or diesel fuel leaking under pressure can penetrate the skin and cause infection or
other injury. To prevent personal injury: Relieve all pressure before disconnecting fluid lines or per-
forming work on the hydraulic system. Before applying pressure, make sure all connections are tight
and all components are in good condition. Never use your hand to check for suspected leaks under
pressure. Use a piece of cardboard or wood for this purpose. If injured by leaking fluid, see your
