Engine Air Cleaner Element (Dual Element) - Clean/Replace
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 Ai

Personal injury can result from air pressure.
Personal injury can result without following prop-
er procedure. When using pressure air, wear a pro-
tective 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 fi ltered, 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 forc e 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.
