WARNING
Death or serious injury can result if the unit becomes
unstable. Properly set the outriggers to level the unit
before moving the booms from the rest.
Properly Setting the Outriggers
With the boom stowed, deploy the outrigger beams to the
desired outrigger conguration. Main (rear) and auxiliary
(front) outriggers have mid and full span placards to aid
the operator in setting outrigger conguration. Figure 6.2
illustrates short, mid, and full span outrigger setups. Once
all beams are properly deployed, lower the outriggers to
a rm footing. Lower the outriggers to level the unit and
remove all tire contact with the ground surface. Level the
unit using the bulls eye level near the outrigger controls.
After setting the front and rear outriggers, verify the unit
is level within one degree by checking the master level
located at the top of the subbase, beside the rotation bear-
ing (refer to Figure 6.3). Levels provided at the tailshelf
and turntable are for reference only, and must be checked
periodically against the master for accuracy.

Control Station
This unit has a hydraulic pilot operated, low pressure
control system. The controls are located adjacent to the
riding seat. Figures 6.4 and 6.5 illustrate the operator’s
control panels.
Left Hand Control Console
The left hand control is a single joystick type control, or
a dual lever type, which activates four separate pressure
reducing valves utilizing the pilot pressure to activate the
main control valves. When a function is operated, the
function’s speed is proportional to the distance the hand
control is shifted. For example, if the boom hand control
is shifted in the boom extend direction at maximum hand
control travel, the boom extends at maximum speed. The
boom will continue to rise until the handle is shifted to
neutral or the boom reaches its maximum travel for the
boom extend function.
