OPERATING INSTRUCTIONS
1. Failure to read, understand, and follow the important information
contained herein may result in a hazardous condition or cause a
hazardous condition to develop.
2. 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.
3. Perform these procedures with the area clear of obstacles and
other personnel.
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 down in the proper position.
b. Make sure the mounting of the fifth wheel to the tractor frame is in good
condition and is tight.
2. back up close to the trailer, centering the kingpin on the throat of the fifth wheel.
STOP.
3. block the trailer wheels, connect the brake lines and light cord. be sure any slack in
the lines is supported so the brake lines do not become tangled. Set the
trailer brakes.
4. Check to see that the trailer is at the proper height for coupling. The leading edge
of the trailer upper coupler plate should initially contact the fifth wheel top bearing
surface 4˝ to 6˝ behind its pivot axis as the tractor backs under the trailer. Follow
instructions published separately for safe operation of the trailer to raise or lower
the trailer to obtain this position.
Attempting to couple with the trailer at an improper height could
result in a false or improper coupling. Failure to properly couple
tractor and trailer could cause separation, resulting in property damage, serious injury
or death.
5. back under the trailer, keeping the trailer kingpin centered in the throat of the
fifth wheel.
6. After picking up the trailer with the fifth wheel — STOP — then continue backing
until the fifth wheel locks firmly on the kingpin. Stopping helps prevent hitting the
kingpin too hard.
7. back up tightly against the kingpin. Then pull forward to test the completeness of
the coupling as an INITIAL check.
A direct visual inspection is required to assure proper coupling. Improper
coupling can pass the initial pull test. Sound is unreliable. Do not take for
granted that you are properly coupled. Get out of the cab and look. Failure to properly
couple tractor and trailer could cause separation, resulting in property damage, serious
injury or death.
