  8. Route the remaining end of the wire harness down the control arm (Figure 8).

  9. Use the previously-removed screws to secure the control panel to the control pod.

  10. Raise the hood.

  11. Route the wire harness along the machine chassis and up to the electrical panel.

  12. Use 2 bolts (M6 x 35 mm) and 2 flange nuts (M6) to secure the slope sensor to the slope-sensor mount (Figure 9).

    g304544
  13. Connect the wire-harness connector labeled P02 to the slope sensor.

  14. Use 2 bolts (M6 x 25 mm) and 2 flange nuts (M6) to secure the slope sensor mount to the electrical panel (Figure 10).

    g307373
  10. Use cable ties to secure the wire harness away from moving parts and pinch points.

  11. Install the battery cover and the dashboard, steering wheel, and front cover.

Calibrating the Sensor

  1. While the machine is on a flat surface, remove the plug from calibration connectors (labeled P05 and P06).

  2. Plug the connectors together.

  3. Turn the ignition key to the ON position, but do not start the engine.

    Note: The LED light blinks as the sensor calibrates.

  4. When the light no longer blinks, turn the ignition key to the OFF position.

  5. Disconnect the calibration connectors and install the plug onto the connectors.

Operation

Using the Slope Sensor

When you start the machine, the LED light illuminates for 5 seconds to indicate that the sensor is functioning properly.

The light and alarm indicates the severity of the slope:

  • No light—normal operating conditions

  • Slow, flashing light—moderate slope

  • Fast, flashing light and audible alarm—steep slope; proceed to a more shallow slope.

Warning

Slopes are a major factor related to loss-of-control and tip-over accidents, which can result in severe injury or death.

Use extreme caution when operating the machine on a slope.
