7 Hydraulic hoses
- Specifically check the condition of the
hydraulic hoses.
- Immediately replace any damaged
hoses.
A
Replace hydraulic hoses if the following
criteria are found on inspection:
- damage of the outer layer to the inlay
(e.g. chafing, cuts, cracks).
- brittleness of the outer layer (cracking of the hose material).
- deformation that does not correspond to the natural shape of the hose or pipe when
depressurised or under pressure or when bent (e.g. separated layers, blistering,
pinched or buckled points).
- leaks.
- damage or deformation to the hose fittings (affecting the sealing function); replace-
ments are not necessary for minor damage to the surface.
- hose coming away from the fitting.
- corrosion of the fitting with a detrimental effect on function and strength.
- failure to comply with the installation requirements.
- period of use has exceeded 6 years. Here it is the date of manufacture of the hy-
draulic hose stated on the fitting that counts, plus 6 years. If the fitting states "2004"
as the date of manufacture, the period of use ends in February 2010.
