Installation and Operation Procedures
5. Inspection and Lubrication
Prior to Use
1. Review the installation. Be sure all nuts
and bolts are in place and properly
torqued/tightened. Be sure all necessary
steps were properly followed and that
all components removed to facilitate
installation are reinstalled.
2. Check the fifth wheel locking mechanism
with a HOLLAND
®
TF-TLN-5001 (2") or
TF-TLN-1500 (3 1/2") Lock Tester. Examine
for proper locking as described in the
"Operating Instructions" of this manual.
This MUST be done to assure that the
mechanism has not been damaged by
shipment, handling, or storage.
Failure to properly install,
operate, or maintain this fifth
wheel could result in tractor
and trailer separation causing
death or serious injury to others.
3. Apply grease to the bearing surface of the
support bracket through the grease fittings
on the side or front of the fifth wheel pockets.
The top plate MUST be lifted up slightly to
ensure proper application of grease.
4. Apply a generous coating of grease to the top
of the fifth wheel plate, where it will contact
the trailer plate.
NOTE: Steps 3 and 4 are NOT required
on HOLLAND
®
Low Lube
™
and
NoLube
™
top plates.
5. Apply a generous coating of grease to the
front lock and lock jaws.
6. Operating Instructions
Failure to read, understand,
and follow the important
information contained herein
may result in a hazardous
condition or cause a hazardous
condition to develop.
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.
7. 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 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
parking brakes.
