OPERATING INSTRUCTIONS
Relative to tractor/trailer operations, there are other checks, inspections,
and procedures not listed here, which are necessary, prudent, and/or
required by law. The following is in addition to these, and pertains to the fifth wheel only.
Perform these procedures with the area clear of obstacles and other personnel.
Coupling Procedures
1. Check out the equipment before coupling.
A. Make sure that the fifth wheel is properly lubricated, that the locks are open,
and that the ramps are tilted in the proper position.
B. Make sure the mounting of the fifth wheel is in good condition and is tight.
C. Make sure the power/brake line and breakaway line (if the trailer is equipped
with electric brakes) and clear of the coupling area.
2. If the tractor is equipped with a body, lower the tailgate.
3. Back up close to the trailer, centering the kingpin on the crotch of the fifth wheel.
STOP!
4. Chock the trailer wheels.
5. Check the trailer height for coupling. The fifth wheel should just touch the kingpin
plate; adjust the landing gears as necessary.
6. Back slowly under the trailer, keeping the kingpin centered in the crotch of the fifth
wheel until the fifth wheel locks firmly on the kingpin. Pull forward to check the
completeness of the coupling as an initial check.
7. Visually check to see that the kingpin is in the fifth wheel lock.
8. Visually check that the locks are properly locked on the kingpin by the following (3) checks.
CHECK 1
The adjustment nut must be seated against the fifth wheel (see Figure 6A).
