Cleaning the Primary Air Cleaner
Elements
NOTICE
Observe the following guidelines if you attempt to
clean the filter element:
Do not tap or strike the filter element in order to re-
move dust.
Do not wash the filter element.
Use low pressure compressed air in order to remove
the dust from the filter element. Air pressure must not
exceed 207 kPa (30 psi). Direct the air flow up the
pleats and down the pleats from the inside of the filter
element. Take extreme care in order to avoid damage
to the pleats.
Do not use air filters with damaged pleats, gaskets, or
seals. Dirt entering the engine will cause damage to
engine components.
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 clean the air cleaner elements by bumping or
tapping. This could damage the seals. Do not use el-
ements 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
Pressurizedaircanbeusedtocleanprimaryair
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).

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 in order to help 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”.
