4-Wheel Steering
Operation
The 4-wheel steering can only be used if the "field /
road” switch is set to “field”. Subsequently, the de-
sired type of steering is selected with the switch for
4-wheel steering and the foot switch.
Switch for 4-Wheel Steering
When the aforementioned switch is set to “field”, it
is possible to select three positions with the switch
for the 4-wheel steering:
•
automatic
•
manual
•
All-wheel steering off.
Automatic
This is the work position for the all-wheel steering.
When the switch is set to this position, it is possi-
ble to select all-wheel steering with the foot switch.
The indicator light on the dashboard indicates if the
machine is in all-wheel steering or two-wheel steer-
ing. If the light for two-wheel steering is on, all-wheel
steering can be selected by pressing the foot
switch. The indicator light for two wheel steering on
the dashboard extinguishes, and the light for all-
wheel steering illuminates. When the front axle
goes through the centre position and the indicator
light for middle position front axle illuminates, the
all-wheel steering is effective and the rear wheels
steer along with the front wheels. To deselect the
all-wheel steering, the foot switch must be de-
pressed again. The indicator light for all wheel steer-
ing on the dashboard extinguishes and the indicator
light for two wheel steering illuminates. When the
rear axle goes through the centre position and the
indicator light for middle position front axle goes on,
the all-wheel steering is deselected and the rear
axle remains in the centre position.
CAUTION
!
Caution: Use the 4-wheel steering
only for turning on the headlands.
Switch off the 4-wheel steering
when driving in the tramlines. Driv-
ing in the tramlines with the 4-
wheel steering switched on can
cause an unstable drive of the ma-
chine and excessive boom motion.
Manual
This is the calibration position for the all-wheel
steering. If the switch is in this position, it is always
possible to select all-wheel steering by depressing
the foot switch. The indicator light for all-wheel
steering comes on. The rear wheel now steers along
with the front wheels, independent of the position of
the front wheels. In this way it is possible to ensure
that the rear wheels are aligned with the front
wheels again, in case the adjustment of the steering
sensors is no longer correct.
4-Wheel Steering Off
In this position the 4-wheel steering can no longer
be used, and depressing the foot switch has no ef-
fect.
Driving on Public Roads
To drive on public roads set the field / road switch to
the "road" position. This is an additional safety fac-
tor to prevent rear axle steering.
If all-wheel steering is selected and the field / road
switch is set to the "road" position, all-wheel steer-
ing is disabled as soon as the rear axle reaches the
centre position.
Turning Machine Off with Rear Wheels
Steered
If the machine is shut down with the rear wheels
steered, problems may occur when the machine is
driven again. It is possible that the rear wheels do
not steer after starting the machine. In this case the
switch for all-wheel steering must be set to the
“manual” position. Depress the foot switch if the
indicator light for all-wheel steering does not come
on. Then turn the steering wheel until the indicator
light for all-wheel steering comes on. The rear
wheels are now centred. Now select either “auto-
matic” or “all-wheel steering off” with the all-wheel
steering switch. It is better to turn the all-wheel
steering off before shutting the machine off.
CAUTION
!
Caution: Before shutting the ma-
chine off, the rear wheels must be
in the centre position and the all-
wheel steering must be turned off.
