Troubleshooting
Problem Cause Trouble-shooting
The central section is
pressing too much
-
Too little pressure is
being transferred to the
side sections
-
Activate the hydraulic lever for
unfolding/folding in such a way that it creates
more pressure on the side sections (see
“Driving and operating”).
-
The drawbar is too high
-
Adjust the drawbar and mid-section (see
“Setting of the machine”)
-
The mid-section is not
horizontal
-
Adjust the drawbar and mid-section (see
“Setting of the machine”)
The outer part of the side
sections are pressing too
much
-
Too little pressure on
the mid-section
-
Activate the hydraulic lever for
unfolding/folding in such a way that it creates
more pressure on the central section (see
“Driving and operating”).
-
The drawbar is too low
-
Adjust the drawbar and mid-section (see
“Setting of the machine”)
-
The mid-section is not
horizontal
-
Adjust the drawbar and mid-section (see
“Setting of the machine”)
The pressure drops on the
manometer
-
The operation lever is
not in the flow position
-
Adjust the pressure on the weight distribution
and put the operation lever into the flow
position (see "Adjustment of the hydraulic
weight distribution")
-
Pilot controlled non-
return valve is
defective
-
Cylinder leaking
(gaskets)
-
Set the weight distribution to 60 – 100 bar and
put the operation lever into the flow position.
Then keep the machine parked for ½ hour. If
the pressure has fallen, it is possible that the
pilot-controlled non-return valve is defective or
there may be dirt in the valve (rinse the valve
and clean the parts or replace it).
-
Check the cylinder for leaks following the
above-mentioned test if the cylinder is
leaking. The gaskets must be replaced.
The side sections are not
following the terrain
-
The weight transfer
hydraulic system is not
in the flow position
-
Put the hydraulic weight distribution system
into the flow position (see "Adjustment of the
hydraulic weight distribution")
Hydraulic el. control is not
working
-
Lack of power to the
box or the valve block
-
Check that the power plug is connected
-
Check the cable for damage or breakage.
Replace damaged cables.
-
Check the tractor’s fuses .
-
Defective valve
-
Defective valve block or dirt in the valve. Clean
or replace it.
