STEERING MODE SELECTION CONTINUED

WARNING
At the start of each work period, when switching on the ignition, the system will by default pre-
select 2WS. If the machine is driven, when the rear axle wheels pass through the center position,
2WS will be selected. If having parked the machine in 4WS/crab and that mode is still required at
startup, the mode will need to be selected prior to moving the machine. Failure to follow this
warning may result in injury or death to personnel.
NOTE
Follow the procedure detailed below to change from one steer mode to another.
1.
Stop the machine and apply the park brake.
NOTE
Sensors on the axles prevent the steer mode from changing until the wheels straighten up or pass
through the "straight ahead" position. During this phase the switch illumination light will flash to
inform you that the change from one mode to the next, though requested, has not yet taken place.
The steering wheel must be rotated back and forth before changing modes.
2.
Press the switch for the required mode, (Figure 59, Items 1, 2, or 3). The switch is spring loaded and will return to its rest
position. The switch (Figure 59, Items 1, 2, or 3) illumination light will flash. Once all the conditions controlling the
change have been met, the light will go steady. The corresponding icon on the EMS unit will be illuminated and if a mode
other than 2-wheel steer has been selected the "Speed Restrict" message will be displayed. If 2-wheel steer has been
selected, the information light on the front console master warning light panel will be illuminated.
