SERVICE

Cleaning of the polyurethane pre-filter element is
recommended every twenty-five (25) operating hours or
(3) months, whichever comes first. Extremely dirty or
dusty conditions may require daily cleanings.
NOTE: Do not oil the pre-filter, paper element damage
can occur.
The paper filter element should be replaced once a year
or every 100 operating hours, more often if used in
extremely dusty conditions.
NOTE: Never run the engine without the complete air
cleaner assembly installed on the engine. Always replace
the filter element with a Tecumseh original replacement
part to maintain proper filtration, emissions compliance
and long engine life.
