Tagging Wires and Hoses.
As soon as the first wire, hose, or tube is disconnected, write number "1" on two tags. Secure one tag
to the wire, hose, or tube and the other tag to the terminal, nipple, or fitting. After disconnecting the
second wire, hose, or tube, write number "2" on two tags. Secure one tag to the wire, hose, or tube, and
the second tag to the terminal, nipple, or fitting. Do the same for all wires, hoses, and tubes.
Note which numbers you used, in pencil, on the illustrations in this manual. This will help you to
accurately re-tag, if tags are removed to perform cleaning and maintenance work.
Remove all tags when finished.

General Instructions :
To insure a long operational life for the M871A3 semitrailer the following is presented to assist
maintenance personnel. This is not meant to supersede or replace current support operations or
authorized publications.
The M871A3 production semitrailer is undercoated at Fontaine Trailer Company prior to delivery.
Worldwide operations present many environmental impacts on the semitrailer from salt water to
ice/snow melt chemicals. Areas of conflict have their own ways of ventilating and damaging the
semitrailer. All these impacts add up to shortened operational life.
Tips:
Keep the semitrailer clean, which will allow for more complete inspection of welds and components. Use
low-pressure water, cleaning detergent, and brushes for cleaning.
Flush out undercarriages, suspensions, and wheel ends with clean low-pressure water if
operating in a salt environment, especially fording, as soon as the mission allows.
Keep debris out of wheel ends and twistlock pockets.
Annually clean deck wood and roll/spray on boiled linseed oil or a good commercial UV wood
protectorate. Apply to top areas of upper and lower deck wood.
Protect all exterior areas from rust--clean off rust, prime metal, and paint area.
Application of 10 wt. oil at oil can points as specified by LO will help protect components and
insure they will work when needed.
Keep bolster plate drain holes free of grease and debris so they drain/air out freely.
Corrosion Protection:
If undercoating has worn off or damage/repair has taken it off the undercarriage, frame, fillets, gussets,
or any other protected area, re-coat with the following:
