Refer to the OEM information in order to determine
the number of times that the air cleaner element can
be cleaned. Do not clean the air filter element more
than three times. The air cleaner element must be
replaced at least one time per year.
Cleaning the air filter element will not extend the life
of the air filter element.
Visually inspect the air cleaner element before
cleaning. Inspect air cleaner elements for damage to
the pleats, the seals, the gaskets and the outer cover.
Discard any damaged air cleaner element.
Two methods may be used in order to clean the air
cleaner element:
• Pressurized air
• Vacuum cleaning
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 air cleaner element is 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 Air Cleaner Element".
Vacuum Cleaning
Vacuum cleaning is a good method for removing
accumulated dirt from the dirty side (outside) of an air
cleaner element. Vacuum cleaning is especially
useful for cleaning the air cleaner element that will
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 an air cleaner
element.
Note: Refer to "Inspecting the Air Cleaner Element".
Inspecting the Air Cleaner Element
Illustration 28
Inspect the clean, dry air cleaner element. Use a 60
watt blue light in a dark room or in a similar facility.
Place the blue light in the air cleaner element. Rotate
the air cleaner element. Inspect the air cleaner
element for tears and/or holes. Inspect the air cleaner
element for light that may show through the filter
material. If it is necessary in order to confirm the
result, compare the air cleaner element to a new air
cleaner element that has the same part number.
Do not use a air cleaner element that has any tears
and/or holes in the filter material. Do not use an air
cleaner element with damaged pleats, gaskets or
seals. Discard damaged air cleaner elements.
