2.21 Hydraulic Hoses/Lines
• Repairs to hydraulic hoses and hydraulic hose lines are forbid-
den! These repairs must be performed by trained personnel.
• All hoses, hose lines and screw connections must be checked
regularly, at least once a year, for leaks and externally visible
damage! Replace any damaged parts immediately! Oil spraying
out can cause injuries and burns.
• Even if they are stored properly and subject to proper loads,
hoses and hose lines are subject to natural aging. Their service
life is therefore limited.
Improper storage, mechanical damage and impermissible
load are the most frequent causes of failure.
The usage period of a hose line should not exceed 6 years,
including a storage time of no more than 2 years (note man-
ufacturer’s date on the hoses).
Use in the limit zone of permissible load may reduce the
duration of the usage period (for example high temperatures,
multi-shift operation).
• Hoses and hose lines must be replaced if any of the following
criteria are encountered during inspections:
-
damage to the outer hose up to the insert (for example worn
spots, cuts and tears)
- embrittlement of the outer layer (formation of cracks in the
hose material)
- deformation when under pressure, without pressure or when
bending which differ from the original shape of the hose or
hose line, for example separation of layers, formation of
bubbles or leaks
- failure to observe requirements of installation
- damage or deformation to the hose fitting that reduces the
stability of the fitting or the hose/fitting connection
- hose coming loose from the fitting
- corrosion of the fitting that reduces functionality and stability
- exceeding storage times and usage periods
• When replacing hoses and hose lines, use only original spare
parts. Install hoses and hose lines properly. Do not confuse
connections.
