Pressurized Air
Pressurized air can be used to clean primary air
cleaner elements that have not been cleaned more
than two times. Pressurized air will not remove
deposits of carbon and oil. Use filtered, dry air with a
maximum pressure of 207 kPa (30 psi).
Illustration 28
Note: When the primary air cleaner elements are
cleaned, always begin with the clean side (inside) in
order to force dirt particles toward the dirty side
(outside).
Aim the hose so that the air flows inside the element
along the length of the filter in order to help prevent
damage to the paper pleats. Do not aim the stream of
air directly at the primary air cleaner element. Dirt
could be forced further into the pleats.
Note: Refer to "Inspecting the Primary Air Cleaner
Elements".
Vacuum Cleaning
Vacuum cleaning is a good method for cleaning
primary air cleaner elements which require daily
cleaning because of a dry, dusty environment.
Cleaning with pressurized air is recommended prior
to vacuum cleaning. Vacuum cleaning will not
remove deposits of carbon and oil.
Note: Refer to "Inspecting the Primary Air Cleaner
Elements".

Inspecting the Primary Air Cleaner
Elements
Illustration 29
Inspect the clean, dry primary air cleaner element.
Use a 60 watt blue light in a dark room or in a similar
g00281692
facility. Place the blue light in the primary air cleaner
element. Rotate the primary air cleaner element.
Inspect the primary air cleaner element for tears and/
or holes. Inspect the primary air cleaner element for
light that may show through the filter material. If it is
necessary in order to confirm the result, compare the
primary air cleaner element to a new primary air
cleaner element that has the same part number.
Do not use a primary air cleaner element that has
any tears and/or holes in the filter material. Do not
use a primary air cleaner element with damaged
pleats, gaskets or seals. Discard damaged primary
air cleaner elements.
Engine Air Cleaner Element
(Single Element - Inspect/
Replace
Refer to Operation and Maintenance Manual,
"Engine Air Cleaner Service Indicator-Inspect".
Never run the engine without an air cleaner element
installed. Never run the engine with a damaged air
cleaner element. Do not use air cleaner elements
with damaged pleats, gaskets or seals. Dirt entering
the engine causes premature wear and damage to
engine components. Air cleaner elements help to pre-
vent airborne debris from entering the air inlet.
Never service the air cleaner element with the engine
running since this will allow dirt to enter the engine.
