ow that your SUSV
has an engine compart-
ment fire detection and
extinguishing system,
your worries about fires
are over, right? Wrong!
There is no guidance
in the unit PMCS on
when
to check or re-
charge the high pressure
CO
2
bottle. If you don’t
make sure the bottle is
full, you could be headed
for trouble.
Here’s what you need
to know
now
. It will be
added to your -20 TM’s
PMCS next time it’s
updated.
High pressure carbon
dioxide cylinders used in
fire extinguisher systems
should be weighed at
least every six months. That information and the
date of the last hydrostatic test of the cylinder should
be posted on the bottle tag.
Weighing and testing is usually done by the post
fire department or a contractor hired by the depart-
ment. In many cases, the testers come to units for the
work. But sometimes you have to take the cylinder
to them.
If your cylinders do not have tags or you need
new tags, ask your supervisor or safety officer to get
you some.
Remember, it serves no purpose to have a fire
extinguishing system if the system’s cylinders are empty or out of service. It’s
your responsibility—and your life.
henever you park a SUSV, be sure to install the front and rear grille covers.
The covers keep snow and debris out of the air intake and cooling systems.
’Course, before you start and operate the SUSV, remove the covers. If
you don’t, the vehicle may overheat, which can ruin the engine and other
components.
The grille covers are part of your basic issue items (BII), stored in the passen-
ger side door. But, the NSNs for the covers aren’t in TM 9-2350-285-10.
The front cover is NSN 2540-01-309-1078 and the rear cover is NSN 2540-
01-309-1079. If you want to save some money, you can make your own using
scrap canvas.
You’ll need a piece of canvas 62x20 inches for the front and 30x28 inches for
the rear. Use an existing cover as a pattern. Remember to cut holes for the
fasteners on the vehicle.
