Work instructions
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.
¾ initially after 10 hours or 50 km
¾ again after 10 hours or 50 km

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!
Allow hydraulic oil heated during operation to cool down before any work
on the hydraulic system.
Observe the notes on hydraulics in the chapter Safety and responsibility.
Check all hydraulic components and hoses for function,
leak tightness, fastening and chafing
Check the hydraulic hoses regularly for damage (cracks, chafing, etc.).
