5 Hydraulic system
The hydraulic system consists of the following assemblies:
•
two single-action hydraulic cylinders.
The hydraulic system is operational when the hydraulic system of the
machine is coupled to the hydraulic system of the carrier vehicle.
5.1 Hydraulic lines
WARNING
Risk of infection to persons if hydraulic oil escapes under high
pressure and penetrates the body!
Ensure that the hydraulic system of the machine and the attachment
is depressurised when coupling and uncoupling the hydraulic lines.
Operate all the control levers of the work hydraulics system of the
machine several times at both sides.
In the event of injuries caused by hydraulic oil, seek immediate
medical attention.
5.1.1 Coupling hydraulic lines
WARNING
Risk of crushing, cutting, grabbing, pulling in and collisions to
persons, if the hydraulic lines are connected incorrectly causing
malfunctions!
•
Note the coloured markings on the hydraulic connectors when
coupling the hydraulic lines.
•
Check the assignment of the hydraulic lines to the individual
hydraulic components on the attachment in case the coloured
markings (dust caps) are missing:
ο
P = pressure line
ο
T = return line
•
Note the maximum permissible operating pressure of the
hydraulic oil of 180 bar.
•
Only connect clean hydraulic connectors.
•
Make sure that no oil escapes into the surroundings when
coupling and uncoupling the hydraulic lines.
•
Insert the hydraulic connector into the hydraulic sleeve until the
hydraulic connector noticeably locks.
•
Check that the connecting points of the hydraulic lines are
seated correctly and sealed.
•
Coupled hydraulic lines:
ο
must give way slightly when cornering without any tension,
kinking or friction,
ο
must not chafe against external parts.
