Front Outrigger Manifold
The solenoids on the front outrigger manifold control the
selection of the front outrigger components, front center jack,
the extend and retract functions of all outrigger components,
and the hydraulic flow to the outrigger hydraulic circuit.
The solenoids on the front outrigger manifold provide the
following functions:
• The SFO (3) solenoid extends or retracts the SFO when
energized. Any time the retract switch on the outrigger
control is depressed, the SFO is first up.
• The component solenoids (2 through 5) control the front
outrigger components. See Figure 3-8 for solenoid
identification.
• The extend (7) retract (8) solenoids control the extend
and retract functions for all outrigger components on
both front and rear outriggers.
Rear Outrigger Manifold
The solenoids on the rear outrigger manifold control the
selection of the rear outrigger components. See Figure 3-9
(1 through 4) for solenoid identification.
