Trouble shooting guide
Not possible to place the
machine in "headland turn"
position.
The hydraulic circuit had not
been pressurized correctly
before attempting to place the
machine in headland turn
position.
Pressure to reach: 80 bar
(1160 psi).
Place the machine in working
position:
- Lower the tractor lift linkage
so that hitch pins are at a
distance 550 mm (1’10’’)
from the ground.
Open the hydraulic valve using
the 18 box spanner supplied
with the machine
Shift the tractor hydraulic valve
in the direction for placing the
machine in working position, to
pressurize the circuit:
100/110 bar (1450/1585 psi) .
Shut-off the hydraulic valve.
Shift the tractor's hydraulic
valve in float position:
There are 3 possibilities:
a) The pressure on the gauge
drops (0 bar).
- Repeat previous tasks.
b) The pressure on the gauge
drops
(The pressure is comprised
between 40 and 80 bar (580 -
1160 psi)).
- Increase accumulator
pressure. See section:
’’Pressure adjustment’’.
c) The pressure is comprised
between 80 and X bar
(1160 - X psi):
- Reduce accumulator
pressure. See section:
’’Pressure adjustment’’.
