Coupling Procedures

8. visually check to see that the kingpin

is in the fifth wheel locks, not
overhanging the fifth wheel or caught
in a grease groove. There should be no
gap between the trailer bolster plate
and the fifth wheel. (See FIGURe 1.)
Check for proper coupling by looking
into the throat of the fifth wheel.
Check the locks as shown in FIGURe 1
for Type “A” locks.

If you do not obtain a
proper coupling, repeat

this sequence. Do not use any fifth wheel
which fails to operate properly. Failure to
properly couple tractor and trailer could
cause separation, resulting in property
damage, serious injury or death.

9. If your fifth wheel is equipped with a

manual secondary lock, engage it.

10. using low gear, retract the landing gear until unloaded. Then, shift to high gear

and continue cranking until they are fully retracted. Fold down or remove the crank
handle and place it in the crank handle holder.

11. Check the brake lines and light cord.
12. Remove the wheel blocks and continue with pre-trip inspection.

Uncoupling Procedures

1. Set trailer brakes with tractor protection switch.
2. back into the kingpin and set emergency brake on the tractor.
3. block the trailer wheels.
4. Wind down the landing gears in high gear until they touch the ground. Shift to low

gear and crank a few extra turns. Do not raise the trailer off the fifth wheel. It may
be necessary to provide a base for the landing gear in poor parking conditions. Fold
down or remove the crank handle and place it in the crank handle holder.

5. Disconnect the light cord and brake lines. Attach the dummy air coupling to keep

foreign material from entering the brake lines.

6. unlock the fifth wheel, including the manual secondary lock if so equipped.
7. Release the tractor emergency brake and pull out slowly from under the trailer.

Let the trailer slide down the fifth wheel and pick-up ramps, being careful that the
trailer landing gear touches the ground with minimal impact.

NOTE: When uncoupling the Type A fifth wheel, it is normal for the release handle to
move to the closed position. It is not necessary to pull the release handle to recouple.
