The drawstring should run just below the outlet valve to make a good seal. The
hood
shouldn’t
go over the eye lenses. If it does, you could break the seal.
Tie
a
bow
under
the
drawstring’s barrel lock once
you have the hood tight. That
keeps the barrel lock from
being jerked and broken if
the drawstring is jerked.
If your suspenders are too
long even after adjustment,
cross them to take up the
slack.
Attaching the strap that runs between your legs may not be comfortable, but it
is necessary. If you forget the strap, the back of the jacket can raise up and you
lose protection.
Just because you wear a size 10 boot doesn’t
automatically mean you’ll wear a size 10 JSLIST
overboot. Normally, you need an overboot 1

sizes larger than your regular boot. So if you wear a
size 10 boot, you probably need a size 12 overboot.
A 10
1
/
2
boot probably needs a 12 overboot, too.
But check and make sure.
Check sampling wheel position.
The
sampling wheel should hit the center
of the probe if you’re to get the best
sample. But the wheel can get so out of
adjustment that it doesn’t even touch the
probe. During your BEFORE PMCS,
check the sampling wheel position and
adjust it if necessary. The procedure is in
TM 3-6665-339-10.
Look for tire safety clips.
Each of the
six tires has a safety clip, which often
goes missing. That could cost you a
wheel. Make sure every tire has a safety
clip before you leave the motor pool.
Post-swim PM.
If your Fox has gone
through deep water, most of its lube has
probably washed out. ASAP, you need
to do a complete re-lubing, including
the tire hubs, axles, main chassis, drive
shafts and propeller shafts.
A better way to Fght mildew.
If
the Fox is left completely closed up
for long periods, condensation leads to
mildew, which leads to a smelly mess.
Most units prevent that by leaving the
glove port door open. Trouble is, if
you forget to close the glove port door
before you open the rear door, you break
the proximity switches or damage the
rear door.
A better way to prevent condensation
is to leave the material access port open.
If you open the rear door while the
access port’s open, nothing is damaged.
During your weekly and monthly
PMCS, check for moisture inside the
Fox. Mop up any you ±nd.
