date on the crimp sleeve (year/month) and the hose (quarter/year) for this purpose.
Hose
Crimp sleeve
Depending on the conditions of use (e.g. weather influences) or in case of higher
strains on the machine the hoses may need to be replaced earlier.
Have the hydraulic system checked by an expert at least once every year.
Follow the country-specific regulations and directives.
Pressure accumulator
Maintenance by trained qualified personnel
Work on equipment with hydraulic accumulators (repairs, connecting pressure gauges,
etc.) may only be performed after relieving the fluid pressure.
Completely bleed the hydraulic line after connecting it.
WARNING!
Lower all hydraulically lifted parts (e.g. wings, packer, undercarriage, etc.) to the
ground before performing any work on the hydraulic system. Depressurise the hydraul-
ics on the tractor and implement side! Empty the pressure accumulators. Refer to the
pressure accumulator item.
Risk of scalding! Allow hydraulic oil and hydraulic components heated during opera-
tion to cool down before any work on the hydraulic system.
Observe the notes on hydraulics in the chapter
