NOTICE
Do not clean the air cleaner elements by bumping or
tapping. This could damage the seals. Do not use ele-
ments with damaged pleats, gaskets or seals. Dam-
aged elements will allow dirt to pass through. Engine
damage could result.
Visually inspect the primary air cleaner elements
before cleaning. Inspect the air cleaner elements for
damage to the seal, the gaskets, and the outer cover.
Discard any damaged air cleaner elements.
There are two common methods that are used to
clean primary air cleaner elements:
• Pressurized air
• Vacuum cleaning
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 46
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 to 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 47
Inspect the clean, dry primary air cleaner element.
Use a 60w 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. To
confirm the result, compare the primary air cleaner
element to a new air cleaner element that has the
same part number.
g00281692
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.
Storing Primary Air Cleaner Elements
If a primary air cleaner element that passes
inspection will not be used, the primary air cleaner
element can be stored for future use.
