25.5 Check hydraulic hoses
Hydraulic hoses are subject to natural ageing. This limits their service life. The recommended
service life is 6 years, including a maximum storage time of 2 years. The date of manufacture is
printed on the hydraulic hoses. When checking hydraulic hoses, the state-specific conditions
(e.g., BGVU) must be observed.
Perform a visual inspection
• Visually inspect all hydraulic hoses for damage and leaks and have them replaced by an
authorised specialist if necessary.
