Lens Protection and Cleaning
If the lenses for the FLIR and
range ±nder are ruined by flying
sand and pebbles, your Avenger
is blinded and your unit is out big
bucks. So any time you’re not ±ring,
which is most of the time,
keep the
FLIR and range fnder covered.
The FLIR has its own protective
cap, which can be ordered with
But the range ±nder has no
cover, so you need to make one
with styrofoam. Cut a piece 12 x
18 inches. Punch a hole in it for the
boresight guide pin cover. Stick it
in front of the range ±nder lenses
so the support bracket holds it in
place.
If you clean the delicate lenses
with something like a dirty rag,
you’ll scratch them. Clean the range
±nder lens only with lens cleaner,
NSN 6810-00-201-0906, and lens
tissue.
Clean
the
FLIR
lens
with
dishwashing soap, NSN 7930-00-
880-4454, and a clean rag. Remove
any soap with a clean rag and
denatured alcohol. You can order
50 pounds of clean rags with NSN
Watch Your Feet
When you’re climbing up
and down on the Avenger,
make sure your feet stay
off the W101 cable for
the ECU/PPU. The cable
grounds the ECU/PPU. If
it’s damaged, you have a
±re hazard.
