5.14.3 Axles Retracted In Out of Transport Position
When the axles are retracted and the machine is in out of transport position, the display
will switch between axles extended and retracted every 0.5 seconds to tell the operator
to extend the axles so the boom can be raised.
5.14.4 Axles In Transient State
When the operator is extending or retracting the axles, the Axles In Transient State
screen will show and the arrows showing axle travel direction will flash. When the axles
are not fully extended or retracted and no axle functions are selected, the green arrows
will show steadily.
