FMTV…
W
hen it comes to cold weather starts, there’s some-
thing that sets great drivers apart from the rest.
They go beyond what the operator’s TM offers.
These tips can prevent damage to the FMTV’s engine
and starter when the weather is between 32°F to
-25°F. And they can put you in a class by yourself.

Trucks…
Freeze-up Means No Brakes
M
oisture in your truck’s air brake lines will freeze in cold weather and block the lines.
Drivers, that leaves you with no brakes!
If your vehicle has an alcohol evaporator to keep
moisture from freezing in the air lines, make sure it has
the alcohol it needs to do the job. NSN 6810-00-
597-3608 gets one gallon of methyl
alcohol. NSN 6810-00-275-
6010 gets a 5-gal can.
I thought
you said there
wasn’t
moisture
in the air brake
lines!
there
isn’t! it’s
all turned
to
ice!!
Make sure it doesn’t
stick in the first place
by adding a thin layer
of
waterless hand
cleaner,
NSN 8520-00-
965-2109, to the inside
of the cover.
That’ll keep
it slick
enough to let
the cap come
off easily in
any
type of
weather.
•
Do not use ether after the engine is up to speed
and is in no danger of stalling.
•
Do not press the
starter
switch
for
longer than 30 seconds.
If the engine doesn’t
start within 30 seconds,
let go of the switch and
wait 30 seconds before
trying
again.
That
keeps the starter from
overheating.
•
Never exceed 1,350 rpm while idling. This is
fast enough to warm up the engine and charge the
batteries, but will avoid
unnecssary wear.
•
No tachometer?
Don’t go past a
hand throttle
position half-way
from the bottom.
That’s approxi-
mately 1,350 rpm.

Combat Vehicles…
cover stuck
like glue?
dropping temperatures
shrink the plastic cover
on your vehicle’s
slave
receptacle.
That
shrinkage makes the
cover stick like
glue
to the receptacle.
A screwdriver will pry it off, but
that often
breaks
the cover.
•
Never press the
ether start switch
unless the engine
is cranking.
