Air Hoses
The compressor’s air hoses are constantly exposed to the elements. That means
they rot, harden and crack with age. Also, air hoses have to withstand pressure and
vibration.
Unreel the hoses. You need both eyes and hands to detect bad hoses. Report any
hoses that show signs of hardness (cracks are clues), mushiness or puffiness.
Dear Editor,
MICLIC crews can prevent
launcher rails from flipping by
checking before they go to the
field for the positive stop on
the right side of the telescop-
ing tube assembly.
The positive stop is not
mentioned in the PMCS in TM
9-1375-215-13&P. But with-
out the stop, the launcher rail
can be raised past its 75° limit
and flip over. Because the stop
is just a straight pin held in
place by a cotter pin, it often
disappears.

Thanks for the tip, Mr. Knoll. And thanks for the good
MICLIC info you have given PS over the years.

tidbits on

maintenance
will help keep
your air

mission-ready
at the
work site.
Get Dirt Out
Your air compressor needs lots
of clean air to run right. Do your
part to keep clean air flowing.
Before the day’s run, squeeze the
dirt out of the dust cap on the bot-
tom of the air canister. Do it more
often if you’re operating in a dusty
or sandy area.
Exercise PM
Some air compressors are known to sit for long periods of time in the motor pool,
especially in Guard and Reserve units.
One way to keep your compressor in working order is to give it some exercise.
Exercise means starting up the compressor and letting it run for at least 20 minutes
every month.
While the compressor is
running, look for any leaks
under it and listen for any
unusual sounds. Also, make
sure you hook up the compres-
sor to its prime mover and take
it for a quick run around the
motor pool, or down the road
and back. Taking the compres-
sor for a ride helps prevent any
“flat spots” in the vehicle’s
wheel bearings and tires.
