List of malfunctions, hydraulic system
Malfunction
Cause
Remedy
No hydraulic function available
Interrupted hydraulic oil
circulation
Switch hydraulic oil circulation
between tractor and machine on
Check hydraulic plugs for wear
Hydraulic hose pipes not
correctly connected (return line
to pressure connection)
Connect hydraulic hose pipes
correctly
Hydraulic plugs not correctly
locked in the hydraulic sleeves
Insert hydraulic plugs into the
hydraulic sleeves until hydraulic
plugs noticeably lock
System screw at hydraulic
control block not properly set
Check setting and readjust if
necessary
Transport floor feed does not
start
Machine overload
Partly discharge machine
manually
Transport floor blocked by
foreign objects
Eliminate foreign objects
Transport floor feed only works
temporarily
Jamming control piston of
transport floor valve
Clean control piston and check
for smoothness during
installation
Tailgate does not open
Closed stop-cock
Open stop-cock
Control block leaking
Defective O-rings
Replace O-rings
Loose tie rod
Tighten tie rod at 22 Nm
Leaking screwed plugs
Seal screwed plugs by means of
liquid threadlocker or sealing
tape.
In the flow line, the pressure
rises to 180 bar, although no
valve is being actuated (open
system)
Screwed-in load-sensing screw
for locking of pressure regulator
Unscrew load-sensing screw
Hydraulic system excessively
heating up
Volume flow from tractor too
large
Adjust volume flow to tractor
valve
Hydraulic plugs too small
Provide appropriately large
hydraulic plugs
Worn hydraulic plugs
Replace hydraulic plugs
Too little hydraulic power in
load-sensing mode
Hydraulic plugs too small
Provide appropriately large
hydraulic plugs
Load-sensing control pressure
too low
Possibly use pressure
intensifier; consult the
manufacturer
