clean cover, bolt, barrel extension, oil buffer, and back plate, using a
small stick covered with a flannel patch to remove dirt from all
recesses.
(2) Wipe all parts with an oily rag.
e. Care of guns in Arctic climates.-In Arctic climates where
excessively low ground temperatures are encountered, special care
must be taken with the guns as follows:
(1) Where guns are left mounted in the aircraft, parts of the gun
not protected by the aircraft should be covered with a tarpaulin or
other suitable covering to protect them from the weather.
(2) Where guns are dismounted from the aircraft and taken into
heated buildings for repair or adjustment. they should be thoroughly
and completely cleaned and oiled immediately, because moisture con-
densing on cold metal in a warm room will cause rusting. After
the guns reach room temperature, they should be wiped free of con-
densed water vapor and oiled again. Oiling is best done with a
slightly oily cloth, using lubricating oil for aircraft instruments and
machine guns.
(3) Low temperatures are encountered at high altitudes. Guns
that are brought down from high altitudes should be treated with
the same care as guns in Arctic climates.
f. Preparation for storage.-(1) Clean gun with particular care.
All parts of gun should be cleaned and wiped thoroughly dry with
rags. In damp climates, particular care must be taken to see that
the rags are dry. After drying, the bare hands should not touch the
parts; handle with an oily rag.
(2) Apply rust preventive compound to all metal parts of gun.
Light rust preventive compound is used for short-time protection,
but should not be used on guns put in permanent storage. It may
be applied with a brush or by dipping. Application of the rust
preventive compound to bore of the machine-gun barrel is done best
by dipping cleaning brush in rust-preventive compound and running
it through the bore two or three times. Prior to placing the weapon
in storage, the bolt should be in the forward position, with firing
pin released. It is good practice to relieve the firing pin tension
whenever the weapon is not in use.
(3) The wooden supports in the packing box must be painted
with rust preventive compound before storing the gun. Place gun
in wooden packing box, handling it with oiled rags.
g. Guns received from storage.-Machine guns received from stor-
age are coated completely with rust preventive compound. Use dry-
cleaning solvent to remove all traces of this grease, particular care37
