The function of hydraulic hose lines must be tested at regular in-
tervals (minimum once a year) by an expert (with a knowledge of
hydraulics).
Hose lines must immediately be replaced in the following in-
stances:
• Damage to the outer layer to the inner lining (abrasion marks,
cracks, cuts, etc.).
• Brittleness of the outer layer (cracking of hose covering).
• Unnatural deformations of the hose line. This applies to both a
pressureless and pressurised condition (e.g. layer separation,
blister formation, crushed areas, kinks).
• Leaks.
• Damage or deformation of hose fittings (impaired sealing
function).
• Hose slips out of the fitting.
