2. Change to two-wheel steer and turn the steering
wheel until the left front wheel is in line with the side
of the machine.
3. Change to either crab steer mode or circle steer
mode, as required.
Steering Arrangement with Self-Aligning Rear
Steering
Your machine may be equipped with self-aligning rear
steering. The self-aligning feature ensures that the rear
wheels are aligned before the steering mode is
changed.
When switch (3) is pressed by the operator, the
machine will not change to the desired steering mode
unless the rear wheels are in the straight ahead
position.
If switch (3) is pressed by the operator and the rear
wheels of the machine are not aligned, the current
steering mode will remain selected. The indicator for the
current steering mode on the display panel will remain
on, and the desired mode indicator will flash. When the
rear wheels are moved to the straight ahead position
by the operator, the steering mode will then change to
the desired mode.
Frame Leveling Control (4)
Improper use of the frame leveling control could result
in personal injury or death. Always level the machine
frame and load before raising the boom. Never use the
frame leveling control when the boom is raised with a
load or without a load. Never use the frame leveling
control to increase the sideways slope of the machine
frame.
If equipped, the frame leveling control (switch) is a
three-position switch.
The frame leveling control is used to level the machine
when the machine is on an uneven surface. The frame
leveling control can cause the frame to tilt to the left or
to the right. The maximum amount of tilt is 10 degrees
in either of these directions.
Lower the boom before you use the frame leveling
control. The boom must be close to the ground.
Press the right side of the switch in order to lower the
right side of the frame. The frame rotates clockwise in
relation to the axles.
Press the left side of the switch in order to lower the left
side of the frame. The frame rotates counterclockwise
in relation to the axles.
When the switch is released, the frame leveling control
returns to the HOLD position.
Use the level indicator to determine when the frame is
level. The frame is level when the bubble is in the middle
of the sight glass.
Frame Level Interlock (If Equipped)
When the boom is extended outward, the frame level
will be isolated. The operator will not be able to use the
frame level function until the boom has been fully
retracted.
The operation of the Frame Level Interlock will not
affect any other functions of the machine hydraulics.
Stabilizer Controls (5), (6)
Machine instability could result if the following
conditions are not observed:
The proper load chart is used. The capacities that are
shown on the load charts are not exceeded.
The boom is fully retracted and lowered to the travel
position before raising the stabilizers.
The areas adjacent to the stabilizers are clear and will
provide uniform support for weight of the machine and
intended load.
The machine is not leveled using the frame level
control when the stabilizers are lowered.
The stabilizers are not used except as described in the
following instructions. Incorrect use of stabilizers
could result in injury or death.
Do not operate the stabilizers when personnel are
nearby. Ensure that personnel stand clear when the
stabilizers are being raised or lowered. Ensure that both
stabilizers are fully raised before moving the machine.
Operating the stabilizers when personnel are nearby
could result in personal injury or death.
