Maintenance overview
Maintenance location Work instructions 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 can lead to loose screw connections
and leaking hydraulic connections.
Once
Retighten all wheel nuts

then retighten daily until the screws have settled and further tightening
is no longer possible.

then always before the start of the season and every 50 operating
hours during use.
Before the season

Hydraulics
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
Safety and responsibility .
Hydraulic system and components Check all hydraulic components and hoses for function,
leak tightness, fastening and chafing
40 h
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):
Crimp sleeve 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.
