Hvordan forstår du følgende pkt D,

Check out the hitch plate before coupling.
A. Inspect the hitch plate for visible damage prior to each loading operation.
B. The hitch plate must be properly lubricated.
C. Check that the correct hitch plate height has been selected.
D. The hitch plate is locked prior to loading and must not be opened.

Hvorfor skal man mon låse før containeren sænkes? Mon det er for at høre et "Klik"? Det står der jo ellers ikke noget om.

Mvh
