Fox NBC Vehicle…
Fox Problems
Dear Editor,
We have suggestions on batteries, brakes, probes and swimming that
can help crews keep their Foxes on the NBC trail:
--Brakes--
If you're driving along and suddenly
it seems like the engine loses power,
check the auxiliary brake (jake
brake). If you've stored items next to
the auxiliary brake, a bump in the road
can throw stuff against the brake
and activate it. You think you have a
serious engine or transmission prob-
lem when it's just the brake. Of
course, the best course is not to
store anything next to the brake.
--Swimming--
Be careful to swim the way your Fox is
supposed to: Enter the water no faster
than 15 kph with the brow plane open and
the propellers turning. We've found if you
enter the water too fast, water can get in
the exhaust and then into the engine,
where it causes all sorts of problems.
--Probe--
The probe has a buckle that
holds it in place in both the
stow and monitoring posi-
tions. Fox crews often ram
the buckle in place like they
would a car seat belt, instead
of pressing the buckle's but-
ton before inserting the
buckle. That breaks the but-
ton and then the probe won't
stay in position, which makes
sampling
difficult.
Just
remember to press the button
before inserting the buckle.
--Batteries--
The NBC battery cable tends to
be stepped on and broken when
crews are loading equipment in the
back of the NBC compartment.
Then you're out of business until
the cable and its connector are
replaced. Prevent that by discon-
necting the cable and putting it
out of way of feet before loading
or unloading stuff. Once you're
finished, reconnect the cable.

If your Fox suddenly seems to lose power,
make sure nothing’s hit the auxiliary brake
Push buckle
button before
inserting
buckle
hey!
slow down,
hopalong! I’m
s’posed to go in the
water
