Operator`s manual

The Outriggers consist of the four main assemblies (see Figure 4-10), the main support (not shown), the
hydraulic cylinder (1), the outrigger arm (5) and the foot pad (7). The main support is welded to the
chassis and has an abutment on its lower end to provide a pivot position (3) for the outrigger arm. The
upper end of the outrigger hydraulic cylinder is attached to the main support and the piston rod is
connected to the outrigger arm (4). The outrigger arm is connected to the main support at one end and
has a foot pad connected to the opposite end. The foot pad and the outrigger arm are connected by pins
(6) and are free to pivot. Hydraulic pressure applied to the piston causes the Outriggers to be extended or
retracted. When fully retracted, a Jack Foot Hook (2) hooks onto the pin (4) that secures the piston rod to
the outrigger arm. The hook prevents outrigger movement when the truck is moving.
The outriggers are equipped with red flashing lights (8). An electric ladder disable switch is provided at
each rear outrigger to prevent deployment of the ladder before the outriggers are deployed. The operation
of the Outriggers is controlled at the two Outrigger Control Panels located on each side of the chassis. A
detailed description of the operation of the Outriggers is given under the heading "Outrigger Hydraulics".
