Structure and function
ZG-B
BAG0051.5 02.14
53
Maximum permissible pressure in oil return: 8 bar
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.
5.9.1
Coupling the hydraulic hose lines
WARNING
Risk of contusions, cutting, catching, drawing in and knocks
from faulty hydraulic functions when the hydraulic hose lines
are connected incorrectly!
When coupling the hydraulic hose lines, observe the coloured mark-
ings on the hydraulic plugs.
Check the compatibility of the hydraulic fluids before connecting
the machine to the hydraulic system of the tractor.
Do not mix any mineral oils with biological oils.
Observe the maximum approved hydraulic fluid pressure of 200
bars.
Only couple clean hydraulic connectors.
Plug the hydraulic connector(s) into the hydraulic sleeves, until
the hydraulic connector(s) audibly lock.
Check the coupling points of the hydraulic hose lines for a cor-
rect, tight seat.
1. Swivel the actuation lever on the spool valve on the tractor to
float position (neutral position).
2. Clean the hydraulic connectors of the hydraulic hose lines be-
fore you couple the hydraulic hose lines to the tractor.
3. Connect the hydraulic hose line(s) to the tractor control unit(s).
5.9.2
Decoupling the hydraulic hose lines
1. Swivel the actuation lever on the tractor control unit on the trac-
tor to float position (neutral position).
2. Unlock the hydraulic connectors from the hydraulic sockets.
3. Protect the hydraulic plug and hydraulic socket against soiling
using the dust protection caps.
4. Place the hydraulic hose lines in the hose cabinet.
