“Caution”
is the word to keep in mind when you hook up the brake air hoses
from a trailer to your 2

/

- or 5-ton truck. If you cross the air lines, the trailer brakes
will lock up, burn out or ruin the tires.
So-o-o-o, make sure your trailer’s hooked up right!
It’s not hard to do. Just locate the SERVICE and EMERGENCY air couplings.
Make sure you use the TM to verify where they are on your trailer.
It’s a good idea to color-code the trailer air hose connectors and the truck’s
gladhand couplings. A dab of blue paint on the SERVICE connectors and red on the
EMERGENCY pair will keep things straight.

Avoid Common Mistakes
Common mistakes made by units include using:
That’s a No Go!
•
unauthorized wire rope assemblies
•
alternate tiedown points on the cargo truck
Proper tension is applied to each sling leg by hand-tightening the turnbuckle until it’s
tight. Then you’ll need to turn it an additional half turn using a bar or wrench inserted
into the turnbuckle’s opening.
•
various combinations of shackles
•
nylon cargo straps to secure shelters
