GENERAL MAINTENANCE INSTRUCTIONS - CONTINUED
TAGGING WIRES AND HOSES - CONTINUED
Whenever possible, identify electrical wires with the number of the terminal or wire to which it connects. If no markings
can be found, tag both wires or wire and terminal, and use the same identifying mark for both. If you cannot tag a wire
because it must fit through a small hole or you cannot reach it, write down the description of the wire and the point to
which it connects, or draw a simple diagram on paper. Be sure to write down enough information so you will be able to
properly connect the wires during assembly. If you need to identify a loose wire, look for identifying number near end of
the wire, stamped on a permanent metal tag. Compare the number to wire numbers on the appropriate electrical sche-
Identify fuel, oil, coolant and hydraulic lines when you are taking off more than one line at the same time. Mark tags
with points to which lines and hoses must be connected. If it is not obvious which end of a line goes where, tag each end
of the line.
Identify and tag other parts by name and installed location as required.
LINES AND PORTS
To keep dirt from contaminating fluid systems when removing and installing fuel, oil, coolant and hydraulic lines, per-
form the following steps:
Clean fittings and surrounding area before disconnecting lines.
Cover, cap, plug (Item 6, WP 0339 00) or tape lines and ports after disconnecting lines. When these materials are
not available, use plastic bags and rubber bands, clean rags (Item 33, WP 0381 00) or other similar materials to pre-
vent dirt from entering system.
Ensure that new and used parts are clean before installing.
Replace all clamps and tiedown straps.
DO NOT remove cover, cap, plug or tape from lines and ports until just before installing lines.
When servicing this vehicle, performing maintenance, or disposing of materials such as engine coolant,
hydraulic fluid, lubricants, battery acids or batteries, consult your unit/local hazardous waste disposal
center or safety office for local regulatory guidance. If further information is needed, please contact The
Army Environmental Hotline at 1-800-872-3845.
Dispose of contaminated drained fluids IAW the Standard Operating Procedures (SOP) of your unit.
