SECTION 3 - CHASSIS & TURNTABLE

4. Repeat step 3 for the left front, right rear, and left rear
outriggers.
5. Power to operate the retract function can be sup-
plied from any 12 volt power source. Connect the
harness’ red alligator clip to positive and the black
alligator clip to negative.
6. Located on the harness is a push button switch.
Pushing the switch will activate all five solenoids, the
four on the outrigger cylinders and the one on the
control valve. At this point the outriggers will auto-
matically begin retracting until the tires and tongue
jack are resting on the ground.
7. To complete the retraction of the outriggers, the
hand pump located on the control valve must be uti-
lized. The pump handle is located inside the valve
compartment. Insert the handle into the pump jack
on the control valve. Pump the handle until all outrig-
ger are fully retracted. Remove the pump handle
and store in the control valve compartment.
8. Disconnect the service outrigger harness from the
four outriggers and control valve. Reconnect the wir-
ing connectors to each cylinder’s solenoid and the
solenoid on the control valve.
3.19 LEVELING, TILT SENSOR CALIBRATION
When all outriggers are set, the leveling system looks at
the angle reported by the bi-directional tilt sensor
mounted on the ground board. The system automatically
adjusts the outriggers until the chassis is level within 1.0°
compound angle before allowing operation of the boom
above elevation.
When Machine Is on a Firm Level Surface
1. Place the empty, stowed machine on a firm level sur-
face.
2. Place a digital level on the frame as shown and level
as well as possible in both x (left Wheel to right
wheel) and y (tongue to tail lights) direction by
adjusting tongue jack, being careful not to set the
level on welds or adjacent plates (On later frames
the fork pocket will be forward of the level)
