WARNING
•
Disconnecting quick disconnect fittings will not relieve hydraulic system pressure. Failure
to follow this warning may result in death or serious injury to personnel.
•
Use extreme caution when disconnecting hydraulic hoses. Contact with hydraulic oil can
damage eyes and skin. Wear eye protection, gloves and protective clothing while
removing hydraulic hoses. Failure to follow this warning may result in death or serious
injury to personnel.
•
Hydraulic fluid under pressure can penetrate the skin and cause injury, blindness, or
death. Pressure may build up in a hydraulic system. DO NOT perform any hydraulic
system service without first shutting down the engine to relieve system pressure. Failure
to follow this warning may result in death or serious injury to personnel.
NOTE
•
Tag all hoses and fittings to aid in installation.
•
Cap all hoses and fittings on removal to prevent contamination.
•
After removal, position hydraulic hoses inside frame, over transmission.
