WARNING
Do NOT disconnect or remove any hydraulic system line or fitting unless engine is shut down and
hydraulic system pressure has been relieved. Tighten all connections before applying pressure. Escap-
ing hydraulic fluid under pressure can penetrate the skin, causing serious injury.
At operating temperature hydraulic oil is hot. Allow hydraulic oil to cool before disconnecting any
hydraulics. Failure to do so could result in injury.
CAUTION
Cap all hoses and tubes to prevent fluid loss and contamination of oil system.
NOTE
Ensure that fluids are contained during performance of inspection, maintenance, testing, adjusting and
repair of the machine. Be prepared to collect fluid with suitable containers before opening any compart-
ment or disassembling any component containing fluids.
Dispose of all fluids according to local regulations and mandates.
Tag all hoses and tubes to aid in installation.
