rivers, you’re in for a rough ride in your 2 1/2- or 5-ton FMTV if you don’t keep
the air springs inflated.
Some operators seem to think
it’s necessary to deflate the air
springs before tilting the cab.
Then they forget to re-inflate
them when they finish their work.
With no air, the cab isn’t level.
Bumps and jars during operation
can make the springs pinch the
bag. A damaged bag won’t hold
air so your backside suffers big
time on a bumpy road.
The only time it’s necessary
to deflate the air springs is
when you’re preparing for air
transport. So leave ‘em inflated
at all other times.
If the air springs on your
truck are flat, re-inflate ‘em.
Just press and turn to the right
the CAB knob on the hydraulic
manifold control panel.

Jack Stands…
Dear Editor,
While walking through some
maintenance areas lately, I’ve
noticed that some jack stands
are not clearly marked with
their tonnage capacity.
The most important marking
on a jack stand is the capac-
ity rating. With no markings,
the stand may be overloaded
and collapse. Not only is the
equipment damaged, but some-
one could be hurt or killed.
I suggest always stenciling the rating on at least two places on each jack
stand. Use large print, too, so the stencil is easy to see.

ok?
{sigh}
I guess
I’m ready to

Watch the Weight!
hey, bob, Are
you
sure
that
stand is rated
to hold up
that load?
yikes! I’d
better
check that
out
right
now!
Editor’s note:
An excellent suggestion, Sir. While the capacity rating should be
stamped into the metal or part of the casting, that stamp is often illegible because
it’s been painted over.
It’s also a good idea to stencil the last date of inspection on the stand as well.
