Once you've used one of the
hydraulic function controls,
leave it in the last position used until the
system is powered up next time.
For example, you've raised the cab
for service. Leave the cab tilt function
control at RAISE until you're ready to
lower the cab again.
Otherwise, the system will begin to
lower the cab as soon as you turn it on.
This could be extremely dangerous if
you aren't ready for it.

S
ecuring the steering wheel on your FMTV should be as simple as possible, to make
sure it gets done quickly and surely, and with no damage to your truck.
You can find almost as many ways to do the job as there are people doing the work.
Problem is, there's only one right way by
the book. Eyeball Para 2-27 in TM 9-2320-
366-10-1, under the heading, "Securing
Vehicle" for the 5-ton models. Para 2-21 of
TM 9-2320-365-10 has the info for the 2
1/2-ton models.
Still, you see some folks loop the chain
around the wheel and steering column,
which causes wiring harness damage. And
you see some folks use the chain as a hand-
hold to get in and out of the cab, which can
damage the turn signal lever.
Install the chain and lock correctly and
use the handhold provided to get in and out.

Here's the
right

That

One More Way to Lock

is
better?

Leave
hydraulic
controls in
position of
last use
Before operation, always
make sure the CAB function
control knob is pushed in and
turned to the right. That ensures
that the cab air bags are inflated.
If you drive on deflated air bags,
they get damaged—and you get an
awful ride.

Push in CAB
control and
turn clockwise
to keep CAB
air bags
inflated
Don’t
touch
any-
thing
on that box
unless the
cab tilt
function
points to
raise!

f you keep up to speed on how your FMTV's cab and suspension hydraulics work,
you won't find yourself down in the dumps. Just remember these two rules:
