Checking and replacing hydraulic hoses
This maintenance chart describes how to inspect and replace the
hydraulic hoses.
You will find the maintenance intervals in the maintenance summary
at the start of this chapter.
Notes
Maintenance, inspection and servicing work poses a particular risk
of accident. Therefore always read the chapter “Safety regulations”
and the description “Other risks during maintenance work” at the be-
ginning of the “Maintenance” chapter.
Caution
Work on hydraulic equipment may only be carried out by persons
with special knowledge and experience in hydraulic systems,
who can provide appropriate certification of their expertise (trai-
ning certificates).
Danger
Hydraulic hose lines must not be more than six years old, including
a storage period of two years. Take note of the date of manufacture
on the hydraulic hose lines.
Risk of burns from hot machine components.
Allow the subassemblies to cool down.
Ensure that all pressures in the hydraulic system and in the delivery
line have fallen to 0 bar.
Wear a face mask and gloves whenever you work on the hydraulic
system. Escaping oil is toxic and can penetrate the skin.
