Out of Transport - Axles Retracted
The Out of Transport - Axles Retracted screen appears if the JLG
Control System has sensed the boom has been moved out of the
transport position with the axles retracted. The screen will remain
until the operator operates one of the controls highlighted on the
screen to correct the condition. In the lower right corner, a check
mark in a green circle indicates there are no serviceable faults
present. If a serviceable fault is present, the numeric fault code
with a safety alert symbol is displayed. Multiple faults will display
in succession. Check the Service Manual for the specific fault
code.
