X.-- CONSERVATION AND CLEANING OF THE
WEAPON
Generally.-- Before putting an Assault Rifle into service the cosmoline, or
grease in which it comes from the factory for conservation must be removed. To
this effect, it must be broken down and its parts washed with benzene or
petroleum and, once it is very clean, a lightly lubricated bore brush should be
passed through the throat and chamber.
The Assault Rifle will be maintained in perfect condition through scrupulous
cleaning. After firing exercises, it should be broken down and all parts that
have been exposed to the effects of the gases of the gunpowder should be
cleaned within 24 hours whenever it is possible.
The use of ash, grinding compound, sand or other materials that may scratch
the parts is strictly prohibited.
In cases where the dirt is such that it cannot be removed with rags, patches or
brushes, the parts will be submerged in petroleum for between 12 and 24 hours
and then cleaned, drying them off afterwards.
The throat and chamber, primarily, should be cleaned carefully with the bore
brush and after a good cleaning should have a lightly lubricated bore brush
passed through them, since the perfect functioning of the weapon depends on
the state in which it is maintained.
Excessive lubrication is not necessary. A drop of oil on the rollers, between the
head and support of the bolt and on the extractor hook is sufficient for correct
functioning.
A weapon excessively lubricated is more likely to jam than one that is clean and
dry, without any lubricant at all; for this reason the drops should be as small as
possible.
When cleaning the weapon, it is not necessary, ever, to separate the rollers from
the bolt head.
