6.7 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 out-
riggers 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 surface.
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 adja-
cent plates (On later frames the fork pocket will be for-
ward of the level).
3. If the board has been replaced or the tilt sensor is not
calibrated, connect an analyzer to the machine at the
ground control console and calibrate tilt sensor. Enter
Level 2 in Analyzer and use the right arrow key to
scroll to Calibrations. Next use the down arrow to
reach TILT SENSOR. Then press the ENTER key .
4. Deploy the outriggers until the machine auto levels. The
machine will indicate it has leveled by beeping three
times and flashing the outrigger indicator lights on the
ground control box.
5. Verify the machine is level using a digital level as shown
in step 1. If not level within 0.5° in each direction, con-
tinue to Setup When Machine Is Not on Firm Level Sur-
face and Adjustment Procedure.
NOTE: The tilt sensor reading may be accessed through the ana-
lyzer: Use the right arrow key to reach DIAGNOSTICS
down arrow key once , right arrow key to
scroll over to SYSTEM, then the down arrow key to
reach Tilt.
