Note: There is no need for the soldier to strip theextractor.It is necessary to use a cartridge for
this, or a special tool, and it is normally done by
the armourer when making o 
perio?Jic inspection.

breech block should be in its forward position
(fig. 17) and the muzzle of the rifle pointing
downwards; the mechanism will then fall into
position correctly.-Close the rifle, still holding the muzzle down-
wards, to prevent any possibility of the slide
rod protruding.

VII. CLEANING AND MAINTENANCE1. GENERAL REMARKSIt must be emphasized that all automatic weap-
ons require constant cleaning and maintenance
and that most of the stoppages mentioned else-
where are the result of the soldier’s negligence
or lack of knowledge of his weapon.All weapons,whether automatic or repeating rifles, should be
cleaned at the end of a day’s firing and special
core must be taken after firing with blank car-
tridges.2. MAINTENANCE OF THE RIFLE

Clean the slide, rear of the barrel and insidethe body;Clean the breech block, firing pin and its hous-
ing;Clean underneath the extractor claw, without
stripping it;

and carefully clean these parts, as they are
exposed to gas fouling;
Clean the gas cylinder and wipe with a slight-
ly oiled rag;this rag should also be passed
through the barrel;
Very slightly oil the moving parts of the me-
chanism.Inspection and maintenance by the unit ar-

3. COMPLETE CLEANING OF BARREL AND GAS
CYLINDERThe barrel and gas cylinder must be cleaned
regularly so that they never get into such a state
that the use of abrasives is necessary; all abra-
sive material such as emery paper, sand, etc., is
always harmful.The full cleaning of barrel and gas cylinder
should be done unhurriedly, when circumstances
permit, 
0s follows:
Wash the barrel, using barrel brush, or sponge,steeped in special oil.
Wash the inside of the front part of the gas
cylinder and gas block,...

Note: The inside of the barrel and inside of front
half of the gas cylinder come into direct contact
with the combustion gases and are also submitted
to friction;they consequently require more care
and attention. Other components are protected
against oxidising by phosphating (parts of the
mechanism and receiver) and the piston and gas
plug are hard chromed.Precaution after firingTo be on the safe side, particularly in hot cli-
mates, and to make subsequent cleaning of barrel
and gas cylinder easier, the...

4. PREPAkATlON OF RIFLE BEFORE FIRINGThe L. A. R. functions with very little or 
proc-
ticolly no lubrication.
Before firing, wipe off any oil remaining on bar-
rel and gas cylinder surfaces; if the piston and
chromed part of the gas plug have been slightly
oiled, dry clean these 
too.The tabulation given below gives on one side
the list of parts which can be slightly oiled, on the
other the list of parts which require no oiling and
which, in some cases, can be adversely affected,
if oiled.
