Interval
After 10 operating hours
Retighten all screw and plug-in
connections as well as the hydraulic
connections.
Even firmly tightened screw connections can come loose
(e.g. because of material settlement or paint residues
between the screw elements). This may lead to loose screw
connections and leaking hydraulic connections.

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 hydraulics on the tractor and implement side!
Empty the pressure accumulators.
Risk of scalding! Allow hydraulic oil and hydraulic components heated
during operation to cool down before any work on the hydraulic system.
Observe the notes on hydraulics in the chapter

Hydraulic system and components
Check all hydraulic components and hoses for function,
leak tightness, fastening and chafing

Hydraulic hoses
Check the hydraulic hoses regularly for damage (cracks, chafing, etc.).
Replace damaged and faulty hoses immediately.
Hydraulic hoses must be replaced after 6 years. Pay attention to the
manufacturing date on the crimp sleeve (year/month) and the hose
(quarter/year):

Hose
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.
