O
perators and mechanics, the trac-
tor truck’s air line cutoff handle is
no handhold for climbing aboard
the catwalk.
A busted handle means you
can’t open and close the air pres-
sure that operates the trailer’s air
brake system.
It may also mean
your tractor truck has an air line
with a slow leak.
The vehicle can’t
build up enough air pressure for
the trailer’s air brake system—not
good!
Instead, use the handhold on the
side of the cab. It’s the safe way to
climb up the catwalk.

Trailers…
I
s there enough “brake” in your trailer’s handbrake?
Most small trailer handbrake adjustments are simple—just turn the handbrake
handle clockwise until the trailer wheels no longer turn when the handbrake is
applied.
But handbrake adjustments for M101- and M116-series trailers are not so simple.
You—the operator—can’t just turn the handles to adjust the handbrakes.
Your favorite mechanic must make the adjustments, using chocks, a jack and a
hex-head wrench.
With that in mind, never drive off with your trailer unless you
know the brakes will hold.
Test ‘em.
After you hook up to
the trailer, apply the handbrakes
and move the trailer slightly to see
if the brakes hold the trailer
wheels.
If they do, go ahead and
finish your mission.
If the brakes don’t hold, call in
your mechanic.
He’s the only one
who can put the “brake” back in
your handbrakes.
Here’s the
latest info
from the folks who provide
the POL Products Guide,
which includes fuels
and lubricants.
The guide gives
stock numbers,
specification numbers
and
recommended
ambient temperature
ranges for fuels and
lubes.
To get the guide or
to get advice on fuels
and lubes for ground
systems, contact tacom.

head
wrench?

or mechanic?
