rivers, the HEMTT’s primary air fil-
ter element needs careful handling to
keep clean air going to the engine.
The primary element has a soft bot-
tom that can’t take much abuse. It cer-
tainly can’t take being thrown around
or beaten against a hard object to loosen
dust and dirt.
If the bottom gets dented or warped,
the element doesn’t fit easily in the air
cleaner canister.
But some drivers just keep pushing
or beating until the canister cover can
be installed. That damages both the
primary and secondary elements, let-
ting dirty air through to the engine air
intake.
If the filter’s air restriction gauge
shows red, remove the primary element
and shake out
as much dust
and dirt as
possible. Don’t
hit the element
against any
object harder
than your hand.
If the element
is so dirty after
cleaning that the
gauge still shows
red, tell your
mechanic. Only
a mechanic can
remove and
replace the secondary element.
hen put to the test, drivers and
mechanics, can you answer the fol-
lowing questions?
What kind of oil or lube is best
for your equipment?
How do you test or recycle an-
tifreeze?
Which hydraulic fluid is right
for your vehicles?
How do you remove moisture
from fuels and fungus from fuel
tanks?
On the outside chance that you
need help for POL answers not
found in your vehicle or equipment
