PREPARATION FOR USE - CONTINUED
There should be no daylight between kingpin plate and fifth wheel, nor should kingpin be
hooked over front of fifth wheel.
10. Visually check coupling.
11. Ease towing vehicle forward to check coupling.
Loop both airhoses and intervehicular cable around the hanger pipe before connecting to
semitrailer so they don't interfere with towing vehicle wheels.
If coupling is not locked, rock towing vehicle back and forth slowly until kingpin is locked. If
hookup failed, repeat steps 4 thru 11.
