  1. Warning—read the Operator’s Manual; a fast flashing light and alarm sounding indicates a steep slope; a slow flashing light indicates a moderate slope; no light indicates normal operating conditions.

Installation

Determine the left and right sides of the machine from the normal operating position.

Preparing the Machine

  1. Park the machine on a level surface.

  2. Disengage the power takeoff and lower the attachments.

  3. Engage the parking brake.

  4. Shut off the engine and remove the key.

  5. Wait for all movement to stop.

  6. Allow machine components to cool.

Installing the Kit

Parts needed for this procedure:

    3. Drill 9/32 inch diameter holes.
    4. Check here for existing holes.

  4. Using the mounting bracket as a template, mark the location of the hole to drill (Figure 1).

  5. Drill 9/32 inch holes into the machine frame (Figure 1).

  6. Install the mounting bracket to the machine frame with 2 bolts (1/4 x 3/4 inch) and 2 flange nuts (1/4 inch).

    Note: Installing the light and removing the decal area is for machines without an InfoCenter only.

  12. For machines with no InfoCenter, cut out the hole in the console decal for the light.

  13. Install the light into the top of the console (Figure 7).

Routing the Wire Harness

  1. Route the wire harness under the seat pan and along the along the existing wire harness in the cross channel (Figure 8).

  2. Install the middle connector to the machine wire harness connector labeled TELEMATICS port or EXPANSION port (Figure 8).

  3. Connect the wire harness to the light and the alarm (Figure 8).

    Route the harness to the controls along the machine’s existing wire harness.

    7. Route the harness under the seat next to the existing harness.

  4. Use the cable ties to connect the new harness to the existing machine harness.

    Note: Ensure the harnesses are secured away from moving parts and hot surfaces.

  5. Connect the battery. Refer to the Operator’s Manual for the procedure.

Installing the Decal

Parts needed for this procedure:

Decal1

Install the decal on the machine as shown in Figure 9.

Calibrating the Sensor

  1. While on a flat surface, remove the plug from the calibration connectors (Figure 10).

  2. Plug the calibration connectors together as shown in Figure 10.

    2. Plug

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

  4. Use the following processes depending what LED light your machine has installed.

    1. Console LED light (Figure 11):

      1. The LED light (Figure 11) blinks as the sensor calibrates.

      2. When the LED light turns off and the sensor beeps once, the sensor is calibrated.

      3. Turn the ignition key to the OFF position.

    2. InfoCenter LED light (Figure 12):

      1. The InfoCenter shows advisory 195, Slope Sensor Calibrating.

        Note: The LED light at the top of the display screen (Figure 12) blinks as the sensor calibrates.

      2. When the InfoCenter shows advisory 196, Slope Sensor Calibrated, the light no longer blinks, and the alarm beeps once, turn the ignition key to the OFF position.

Operation

Use the following procedures depending what your machine has installed.

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.

Using the Slope Sensor with the LED Light

The light and alarm indicates the severity of the slope (Figure 11):

  • No light—normal operating conditions

  • Slow, flashing red light—moderate slope

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

Using the Slope Sensor with an InfoCenter

The light and alarm indicates the severity of the slope (Figure 12):

  • No light—normal operating conditions

  • Slow, flashing red light—moderate slope

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