If the operating lever is difficult to turn or does not turn at all, the
jamming eccentric in the trailer arm housing must be cleaned and

be caused by the following:
♦ Defective lock: replace bolt with lock (repair measure)

trailer arm (repair measure)
♦ Pin seizing up: clean and treat with lubricant for trailer coupling
device from the ⇒ Electronic Catalogue of Original Parts . If
this does not help, send it for repair to the manufacturer or
replace it with a new one.
