Outrigger Control Panel
There is one outrigger control panel on each side of the
machine fender decking as shown in Figure 3-1 and
Figure 3-3. The following details apply to both control panels
as indicated.
• The panel on the right side operates the outrigger
beams for that side only.
• The panel on the left side operates the outrigger
beams for that side only.
• The stabilizers (jacks) may be operated from the left
or right side of the unit.
• Each control panel contains a control switch for
raising and lowering the single front outrigger
(SFO).
• Each control panel contains an emergency stop
switch.
Outrigger Beam Selector Switch
The outrigger beam selector switch (1, Figure 3-3) is used to
operate the front or rear outrigger beam on the same side of
the crane the ground control is located.
Extend/Retract Switch
The extend/retract switch (2, Figure 3-3) will operate both
the outrigger beams or the jacks.
After pushing the desired selector switch, pushing the
extend/retract switch energizes the control solenoid to allow
hydraulic fluid to flow through the control solenoid valve and
the individual solenoid valve and move the selected compo-
nent in the desired direction. In addition, when the switch is
put to either position, a signal is sent to the engine ECM to
increase engine speed above idle for operation of the outrig-
gers.
Single Front Outrigger Switch
The single front outrigger switch (SFO) (3, Figure 3-3) is
located in the center of the ground station outrigger control
panel. It must be used with the extend/retract switch to con-
trol the operation of the SFO. The SFO will retract automati-
cally when any of the other four jacks are retracted;
therefore, it must be reset if lifting is to be continued.
Jack Selector Switch
Use the jack selector switch (4, Figure 3-3) to indicate which
jack you desire to operate.
Emergency Stop Switch
There is an emergency stop switch (5, Figure 3-3) on the
outrigger controls on each side of the carrier. Pressing either
switch shuts down the engine.
NOTE: Only use the emergency stop switch in the case of
an emergency to shut down the engine; do not use
the emergency stop switch regularly as a means of
turning off the machine.
