epairmen will be left crying over
the cryogenics in their Avenger, Stinger,
Air-to-Air-Stinger (ATAS), or Line-
backer missile systems if they miss
this PM:
Use only the purest argon gas
. NSN
9135-00-882-1793 brings argon that’s
99.99 percent
pure. That’s
what your
missile system
needs. Anything
less than pure
argon will soon
cause the
cryogenics to
stop working,
which means
you won’t be
hitting many
targets.
Avenger, Stinger, ATAS, Linebacker . . .
And don’t forget to purge the sys-
tem after you change the cartridge.
Otherwise, the cryogenics will be
contaminated.
Do the PMCS called for on the
2-liter argon reservoirs in the -23
TMs for these system
s...
and no
more
. The reservoirs must be repaired
in an antiseptic room under controlled
conditions. Otherwise, they’ll be con-
taminated and repairs can only be done
at depot. If you spot reservoir prob-
lems during PMCS, don’t try to fix
them yourself.
Change dessicant cartridge
every 60 days of operation
Regularly change the dessicant
cartridge in the GCU-31 gas charg-
ing unit
. Do it every 60 days when
you’re operating or every 180 days
when you’re not operating, like it says
in your PMCS. If you don’t, water va-
por contaminates the argon. See Para
6-17 in TM 9-1450-1431-14&P for in-
structions on replacing the cartridge,
NSN 4440-01-249-8864. Remember to
give the backup ring and preformed
packing only a
light
coat of Type III
grease, NSN 9150-00-961-8995. If you
use too much, the cryogenics system
will clog.
i don't
know what to
tell you! i'm
hot
and
sweaty
. maybe it's
the
flu
?!

i don't
get it, we
just
charged
your
cryogenic
system!
Use only purest Argon
uh-oh!
maybe i
shouldn't have used
that
cheap
argon
!
Do PMCS on argon reservoirs—and no more!
