WARNING
Do not remove any hydraulic system fitting unless engine is shut down and hydraulic system
pressure has been relieved. Tighten all connections before applying pressure. Escaping hydraulic
fluid under pressure can penetrate the skin, causing injury or death to personnel.
At operating temperature, hydraulic oil is hot. Allow hydraulic oil to cool before disconnecting any
hydraulic fitting. Failure to follow this warning may result in injury to personnel.
