Machine Dimension and Calibration Troubleshooting
Verify the Arm Sensor Calibrations
Perform the following in order to verify the "Arm Sensor Calibrations":
Start the display in "Service" mode. Press the "OK" key and hold the"OK" key when the display is powered up.
Select the "Setup Menu". Press "Configuration".
Use the up arrow key or the down arrow key in order to select "Diagnostics".
Press the button in order to select "Arm Sensors". A screen similar to Illustration 20 appears.

Place the machine on level ground. Position the boom so that the boom pins are level with the ground. The boom sensor must be level with the ground. The "Boom Sensor Angle" should read approximately zero (0) degrees. If the "Boom Sensor Angle" does not read approximately zero (0) degrees, then check the boom sensor calibration.
Position the stick so that the stick pins are perpendicular to the ground. The stick sensor must be perpendicular to the ground. The "Stick Sensor Angle" should read approximately –90 degrees. If the "Stick Sensor Angle" does not read approximately –90 degrees, then check the stick sensor calibration.
Position the bucket so that the bucket linkage is level with the ground. The bucket sensor must be level with the ground. The "Bucket Sensor Angle" should read approximately zero (0) degrees. If the "Bucket Sensor Angle" does not read approximately zero (0) degrees, then check the bucket sensor calibration.
Place the machine on reasonably level ground. Record the "Pitch Sensor Angle". Rotate the machine cab 180 degrees. Note the "Pitch Sensor Angle" again. After rotating the machine cab 180 degrees, the "Pitch Sensor Angle" should be the negative value of the first angle that was recorded. For example, if the "Pitch Angle" was –3.1 degrees, then the "Pitch Angle" should read 3.1 degrees after rotating the machine cab 180 degrees. If the values are not correct, then the pitch sensor calibration must be performed again.
If the optional tilt bucket kit was installed, then position the tilt bucket so that the tilt bucket is level with the ground. The tilt sensor should also be level with the ground. The "Tilt Bucket Sensor Angle" should read approximately zero (0) degrees. If the "Tilt Bucket Sensor Angle" does not read approximately zero (0) degrees, check the tilt bucket sensor calibration or the tilt bucket sensor mounting.Verify the Arm Positions (GPS measurements)
Perform the following steps in order to verify the arm positions, that is the GPS measurements.
Start the display in service mode. Press the "OK" key and hold the "OK" key when the display is powered up.
Press the display button in order to select Setup Menu. Press the display button in order to select "Configuration".
Use the up arrow key or the down arrow key in order to select "Diagnostics".
Press the display button in order to select "Arm Positions".
