RT540E OPERATOR MANUAL OPERATING CONTROLS AND PROCEDURES
Swing/Telescope or Swing/Auxiliary Hoist
Control Lever (Dual Axis)
The Swing/Telescope or Swing/Auxiliary Hoist (Swing/Tele
or Swing/Aux) Control Lever (2) (Figure 3-6) is located on
the end of the left armrest. The lever controls the swing and,
when the crane is not equipped with an auxiliary hoist,
telescope functions. When equipped with an auxiliary hoist,
the lever controls swing and auxiliary hoist functions and
telescope functions are controlled through a foot pedal.
Positioning the lever to the left or right actuates a control
valve to provide 360 degree continuous rotation in the
desired direction. Positioning the lever forward actuates the
control valve to telescope the boom out and pulling the lever
back actuates the boom to telescope in.
If equipped with an auxiliary hoist, positioning the lever
forward actuates the control valve to let out hoist cable and
pulling the lever back reels the cable in. Moving the lever in a
diagonal direction actuates the two functions simultaneously.
Main Hoist Enable Switch
The Main Hoist Enable Switch (3) (Figure 3-6) is a
momentary switch that is located on the right armrest. Press
once to enable hoist; press again to disable hoist. Pressing
the switch twice rapidly enables hoist at high speed.
Pressing once and holding the switch for about 2 seconds
also enables high speed.
Boom Up Bypass Switch (Optional)
The Boom Up Bypass Switch (4) (Figure 3-6) is a momentary
two-position rocker switch that, when installed, is located on
the right armrest. While lift function is enabled and in a RCL
lockout condition, activating the Boom Up Bypass Switch will
enable boom lift up.
Lift Function Enable Switch
The Lift Function Enable switch (5) (Figure 3-6) is a
momentary switch that enables boom up and boom down.
Jog Dial
The Jog Dial Control (6) (Figure 3-6) is located on the right
arm rest. It selects and chooses functions on the screen(s) to
navigate the Crane Control System.
Outrigger Function Enable Switch
The Outrigger Function Enable Switch (7) (Figure 3-6)
allows the operator to switch between extension/retraction of
the outriggers and raising/lowering of the jacks. Press and
hold this switch to force the lower screen display to change
to the outrigger page.
Differential Lock On/Off Switch (Optional)
The Differential Lock Switch (8) (Figure 3-6) is located on the
left arm rest. It engages the differential lock function for
better traction, when Four Wheel Drive is selected, on poor
road or highway surfaces. It can be activated for a maximum
of 30 seconds at a time.
NOTE: The differential lock will only work when the crane
is in the 4WD mode.
Rear Steer Switch
The Rear Steer Control Switch (9) (Figure 3-6) is a three-
position, spring centered to off, rocker switch, located on the
left armrest. Press the bottom of the switch to actuate a
control valve to turn the rear wheels to the left, causing the
crane to turn to the right. Press the top of the switch to
actuate a control valve to turn the rear wheels to the right,
causing the crane to turn to the left. When the wheels are not
centered the Wheels Not Centered icon on the CCS
Operating Display illuminates. Releasing the switch causes it
to return to the center off position.
To straighten the rear wheels press the switch until the Rear
Wheels Not Centered icon indicator light goes off.
Auxiliary Hoist Enable Switch (Optional)
The Auxiliary Hoist Enable Switch (10) (Figure 3-6) is
located on the left arm rest. It enables the Auxiliary Hoist and
sets the high speed the same as the Main Hoist Enable
Switch does for the Main Hoist.
Boom Telescope Enable Switch
The Boom Telescope Enable Switch (11) (Figure 3-6) is
located on the left arm rest. It enables the boom telescoping
function for the optional Telescope Control Foot Pedal, or for
the Control Lever (joystick) if there is no auxiliary hoist.
Swing Enable Switch
The Swing Enable Switch (12) (Figure 3-6) is located on the
left arm rest. This two-position rocker switch (On/Off) is used
to control a hydraulic valve that directs a regulated flow of
pressure to and from the swing brake. When the joystick
