Never let the hydraulic oil temperature increase too much while the
machine is in operation.
Using small oil tanks for large flow rates causes hydraulic oil to heat
up quickly. The oil tank capacity should be at least twice that of the
flow rate. If the oil is heating up too much, have an oil cooler installed
at a specialised workshop.
WARNING
Danger of infection from escaping hydraulic fluid at high pres-
sure!
When coupling and uncoupling the hydraulic hose lines, ensure that
the hydraulic system is depressurised on both the machine and trac-
tor sides.
If you are injured by hydraulic fluid, contact a doctor immediately.
5.7.1
Coupling the hydraulic hose lines
WARNING
Danger from faulty hydraulic functions in event of incorrectly
connected hydraulic hose lines!
When coupling the hydraulic hose lines, observe the coloured mark-
ings on the hydraulic plugs. Here, see "Hydraulic connections", page
45.
•
Observe the maximum approved hydraulic operating pressure of
210 bar.
•
Check the compatibility of the hydraulic fluids before connecting
the machine to the hydraulic system of your tractor.
•
Do not mix any mineral oils with biological oils.
•
Slide the hydraulic connector(s) into the hydraulic sleeves until
they are heard to engage.
•
Check the coupling points of the hydraulic hose lines for a cor-
rect, tight seat.
•
Coupled hydraulic hose lines
ο
must easily give way to all movements in bends without
tensioning, kinking or rubbing.
ο
must not rub against other parts.
1. Swivel the actuation lever on the control valve on the tractor to
float position (neutral position).
2. Clean the hydraulic plug for the hydraulic hose lines before con-
necting them to the tractor.
3. Couple the hydraulic hose lines with the tractor control units.
