Attaching and removing the machine at the tractor's rear three-
point linkage
GH HH Super SMARTCUT BAF0009.3 05.17
WARNING
Risk of infection from hydraulic fluid escaping at high pressure.
When coupling/uncoupling the hydraulic hose line, ensure that the
hydraulic system is not under pressure on the tractor or machine side.
If you are injured by hydraulic fluid, contact a doctor immediately.
Check the maximum permissible pressure in oil return!
Therefore do not connect the oil return to the tractor control unit, but
to a pressure-free oil return flow with a large plug coupling.
WARNING
For the oil return, use only DN16 lines and select short return
paths.
Pressurise the hydraulic system only when the free return has
been correctly coupled.
Install the coupling union (supplied) on the pressure-free oil return
flow.
5.4.1 Coupling hydraulic hose lines
WARNING
Risk of crushing, cutting, being trapped or drawn in, or impact
through faulty hydraulic functions when hydraulic hose lines are
incorrectly connected.
When coupling the hydraulic hose lines, please note the coloured
markings on the hydraulic plugs.
• Check the compatibility of the hydraulic fluids before connecting
the machine to the tractor hydraulic system.
Do not mix any mineral oils with biological oils.
• Observe the maximum permissible hydraulic fluid pressure of
200 bars.
• Only couple clean hydraulic connectors.
•
Plug the hydraulic plug(s) into the hydraulic sockets until you can
feel the hydraulic plug(s) locking.
• Check the coupling points on the hydraulic hose lines, to see if
they are sitting correctly and are sealed.
1. Swivel the actuation lever on the control valve on the tractor to
float position (neutral position).
2. Clean the hydraulic plugs on the hydraulic hose lines before
coupling the hydraulic hose lines with the tractor.
3. Connect the hydraulic hose line(s) to the tractor control unit(s).
