Engine Air Cleaner Element (Dual Element) - Clean/Replace
2. The secondary air cleaner element should be
removed and discarded for every three cleanings
of the primary air cleaner element.
Note: Refer to "Cleaning the Primary Air Cleaner
Elements".
3. Cover the air inlet with tape in order to keep dirt
out.
4. Clean the inside of the air cleaner cover and body
with a clean, dry cloth.
5. Remove the tapefrom the air inlet. Install the
secondary air cleaner element. Install a primary air
cleaner element that is new or cleaned.
6. Install the air cleaner cover.
7. Reset the air cleaner service indicator.
Cleaning the Primary Air Cleaner
Elements
Refer to the OEM information in order to determine
the number of times that the primary filter element
can be cleaned. When the primary air cleaner
element is cleaned, check for rips or tears in the filter
material. The primary air cleaner element should be
replaced at least one time per year. This replacement
should be performed regardless of the number of
cleanings.
NOTICE
Do not tap or strike the air cleaner element.
Do not wash the primary air cleaner element.
Use low pressure (207 kPa; 30 psi maximum) pres-
surised air or vacuum cleaning to clean the primary
air cleaner element.
Take extreme care in order to avoid damage to the air
cleaner elements.
Do not use air cleaner elements that have damaged
pleats, gaskets or seals.
Refer to the OEM information in order to determine
the number of times that the primary air cleaner
element can be cleaned. Do not clean the primary air
filter element more than three times. The primary 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 primary 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
primary 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 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.
