Engine Air Cleaner Element (Dual Element) - Clean/Replace
Replace the dirty air cleaner elements with clean air
cleaner elements. Before installation, the air cleaner
elements should be thoroughly checked for tears
and/or holes in the filter material. Inspect the gasket
or the seal of the air cleaner element for damage.
Maintain a supply of suitable air cleaner elements for
replacement purposes.
Dual Element Air Cleaners
The dual element air cleaner contains a primary air
cleaner element and a secondary air cleaner
element. The primary air cleaner element can be
used up to six times if the element is properly
cleaned and properly inspected. 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.
The secondary air cleaner element is not serviceable
or washable. Refer to the OEM information for
instructions in order to replace the secondary air
cleaner element. When the engine is operating in
environments that are dusty or dirty, air cleaner
elements may require more frequent replacement.

Cleaning the Primary Air Cleaner
Elements
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.

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
