Pressurized Air
Personal injury can result from air pressure.
Personal injury can result without following prop-
er procedure. When using pressure air, wear a
protective face shield and protective clothing.
Maximum air pressure at the nozzle must be less
than 205 kPa (30 psi) for cleaning purposes.
Pressurized air can be used to clean primary air
cleaner elements that have not been cleaned more
than three times. Use filtered, dry air with a maximum
pressure of 207 kPa (30 psi). Pressurized air will not
remove deposits of carbon and oil.

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 air hose so that air flows along the length of
the filter. Follow the direction of the paper pleats in
order to prevent damage to the pleats. Do not aim the
air directly at the face of the paper pleats.
Note: Refer to "Inspecting the Primary Air Cleaner
Elements".
Vacuum Cleaning
Vacuum cleaning is a good method for removing
accumulated dirt from the dirty side (outside) of a
primary air cleaner element. Vacuum cleaning is
especially useful for cleaning primary air cleaner
elements which require daily cleaning because of a
dry, dusty environment.
Cleaning from the clean side (inside) with
pressurized air is recommended prior to vacuum
cleaning the dirty side (outside) of a primary air
cleaner element.
Note: Refer to "Inspecting the Primary Air Cleaner
Elements".
Inspecting the Primary Air Cleaner
Elements
Illustration 43
Inspect the clean, dry primary air cleaner element.
Use a 60 watt blue light in a dark room or in a similar
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.
