O
perators, keep these PM pointers in mind so your vibratory roller keeps on rolling
during paving operations.
Circuit Breaker Panel
Water plays havoc with the vehicle’s circuit breakers. Over time, any moisture that
leaks or builds up inside the circuit breaker housing corrodes the breakers and shorts
them out. That means the vibratory roller will run erratically or not at all!

Keep Roller Rolling With PM
PLS and HEMTT
trucks that
have enhanced
container
handling units
(E-CHU) with serial
numbers 1422
and above have
redesigned lower
storage locks.
if those locks
aren’t
disengaged
before raising the E-CHU from its
stowed position, a shear pin inside
each lock is designed to snap.
That prevents
any
damage
to
the E-CHU.
it’s up to
you
to replace
those broken shear pins
when that happens.
So check for
snapped
or
missing
shear pins
before
each day’s run.

Need to replace the
shear pin on your PLS
or HEMTT LHS truck?
I’ve got
your NSNs
right here!
What?
what are
you
saying?
I
don’t
understand!
My circuit

is taking on
water!
And I need
you
to do
something
about it!
