of an inch in thickness to ensure hitch will operate properly. Lube plates must be 10 inches in diameter or larger to
properly distribute king pin weight.

3. Before each trip or maneuver, operate the handle and check that the jaws open and close freely.

Failure to follow this instruction may result in king pin being too high and coming to rest on top of closed jaws or
not completely inside jaws. (See Fig. 9). This could result in trailer separating from hitch. Trailer separation may
result in death or serious injury if anyone is under the trailer or between truck and trailer when separation occurs.
