140-2710

  1. 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.

    4. Nut

  2. Torque the fasteners to 4.2 N∙m (37 in-lb).

  3. Remove and discard the plastic plugs securing the parking brake cover to the machine (Figure 2). Remove the parking brake cover.

    Note: Use a putty knife or a plastic-fastener removal tool when removing the plastic plugs.

    3. Plastic nut

  2. Remove the plastic nut from the alarm and use it to secure the alarm through the opening left by the knockout (Figure 4).

  3. Install the previously removed parking brake cover using 4 new plastic plugs to secure it to the machine (Figure 2).

    Note: You do not need to install the 2 outer plastic plugs on machines with cabs.

Routing the Wire Harness

  1. Plug the 90° connector into the bottom of the sensor module (Figure 5).

  4. Secure the harness to the hydraulic tube with a cable tie as shown in Figure 5.

  5. Secure the harness away from A/C compressor belt on cab units as shown in Figure 6.

Installing the Decal

Parts needed for this procedure:

Decal1

  1. Install the decal on the machine as shown in Figure 7.

  2. Install the front left tire, torque the lug nuts, and lower the machine. Refer to Installing the Front Tires in the Operator’s Manual.

Calibrating the Sensor

  1. While on a flat surface, remove the plug from the calibration connectors (Figure 8).

    2. Plug

  2. Plug the calibration connectors together as shown in Figure 8.

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

  4. The displays shows Slope Sensor Calibrating.

    Note: The LED light next to the display screen (Figure 9) is solid green as the sensor calibrates.

Operation

Using the Slope Sensor

The light and alarm indicates the severity of the slope:

  • Green light—normal operating conditions

  • Slow, flashing red light and B2713 displaying on the screen—moderate slope

  • Fast, flashing red light, audible alarm, and B2714 displaying on the screen—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.
