11.11.2.3 Inspection criteria for hydraulic hose lines
In the interests of your own safety:
173
Replace hydraulic hose lines immediately as soon as you discover
the following defects:
• Damage to the outer layer through to the middle layer (e.g. worn
spots, cuts, tearing).
• Increasing brittleness of outer layer (crack formation on hose
material).
• Unnatural deformation of the hydraulic hose line, both in
pressure-less as well as pressurised condition or with bending
(e.g. layer separation, blistering, pinch or kink sites).
• Leaks.
• Hose fitting damage, deformation or leakage. Minor surface
damage does not necessitate replacement.
• Hose slipping out of the fitting.
• Corrosion of fitting, which can impair functions and resistance.
• Incorrectly laid hydraulic hose lines e.g. disregarded bending
radii, routing over sharp edges.
• Exceeding limit of 6 years of use. For further information please
consult the chapter "Flagging and length of usage of hydraulic
hose lines", page .
