Troubleshooting hydraulic hoses

Oil under high pressure!
Personal injury!
Always depressurize hydraulic and brake systems
before starting to work on the systems.
1 Depressurize the hydraulic and brake systems, see section B
Safety.
2 Study the relevant hydraulic diagram, check between whichev-
er components the suspect hose is connected and correspond-
ingly where it is spliced.
3 Locate the hose on the machine.
Start at one component and follow the hose to the next com-
ponent.
4 Inspect the entire hose and splicing points with respect to chaf-
ing damage, pinching damage and leaks.
Change damaged hoses. When removing a hydraulic hose,
change of O-ring is always recommended on the hoses that
have these (ORFS).
