After service and teach-in of a Hup 32-27 The jib was required to be folded for weathervane. Went through the book to confirm the steps were completed in order and done correctly.
The crane would fold the jib tip but not the complete jib. A red x would appear when weathervane target was selected.
The image for the Trolley position if glanced at quickly is difficult to decern the correct trolley placement. 
Note: The trolley must not be in the transport position.
Trolley in, until the trolley is completely inside the first jib section. This will allow the jib to fold for weathervane.
