21-2.1. General
a.
Maintenance Forms and Records. Every
mission begins and ends with the paperwork. There isn't
much of it, but you have to keep it up. The forms and
records you fill out have several uses; they are a
permanent
record
of
the
services,
repairs,
and
modifications made on your equipment; they are reports
to Organizational Maintenance and to your Commander;
and they are a checklist for you when you want to know
what is wrong with the equipment after its last use, and
whether those faults have been fixed. For information
you need on forms and records, see: DA Pamphlet 738-
750.

21-2.2. General Maintenance Procedures
a.
Cleanliness. Dirt, grease, oil, and debris only
get in the way and may cover up a serious problem.
Clean as you work and as needed. Use dry cleaning
solvent Type II, Fed. Spec PD-680, on all metal
surfaces.
WARNING
Dry cleaning solvent, Type II, Fed.
Spec
PD-680,
is
potentially
dangerous
to
personnel
and
property. Do not use near open
flame or excessive heat. Flash point
of solvent is 139° F (59.4° C).
b.
Bolts, Nuts, and Screws. Check them all for
obvious looseness, missing, bent, or broken condition.
You can't try them all with a tool, of course, but look for
chipped paint, bare metal, or rust around bolt heads. If
you find one you think is loose, tighten it, or report it to
Organizational Maintenance.
c.
Welds. Look for loose or chipped paint, rust, or
gaps where parts are welded together. If you find a bad
weld, report it to Organizational Maintenance.
d.
Electric Wires and Connectors. Look for
cracked or broken insulation, bare wires, and loose or
broken connectors. Check for loose connectors and
make sure the wires are in good shape. Report loose
connectors
and
bad
wires
to
organizational
maintenance.
