Replace the dirty air cleaner elements with new 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 Cleaner
The dual element air cleaner contains a primary air
cleaner element and a secondary air cleaner
element.
When the engine is operating in environments that
are dusty or dirty, air cleaner elements may require
more frequent replacement.
If equipped, perform maintenance on the pre-cleaner
or the dust bowl before performing maintenance on
the air filter elements.
