Explanation

The bending leg must be fully deployed or fully retracted before any lifting can take place.

If arms mode is selected and the bending leg sensors indicate that the bending leg is not fully deployed or not fully retracted then this message is displayed.

Causes

• Bending leg not fully extended or not fully retracted
• Bending leg fully extended sensor faulty or needs adjustment
• Bending leg fully retracted sensor faulty or needs adjustment

Operator Actions

• Fully extend or fully retract bending leg and retry arms mode
• Use override code to continue operation
• Request service

Service Tasks

• Go to VIEW SENSOR VALUES, VIEW SPECIAL OPTIONS, FRONT or REAR ANKLE.
• Actuate the bending leg between the fully retracted and fully extended positions. Observe that the ANKLE POSITION should change from fully retracted to partially extended to fully extended. The individual switch values are displayed and should be as follows.

If any sensor switch displays incorrect values then replace it.
