Passage below pin must be free.
Please consult repair leaflet (available on request) for details of

Support ring for drawbar eye must be replaced if drawbar
eye could touch lower bush because of wear or if wear limit H
min. of 16.5 mm (see Fig. 9) has been reached.
Lower bush must not be damaged under any circumstances as
this will impair closure of coupling.
Take care to prevent risk of accident!
Always grease support ring to reduce wear (please consult repair
