Cleaning/Replacing Air Cleaner
Your engine has an air cleaner which helps prevent
premature engine wear and failure. NEVER run engine
without complete air cleaner installed on engine. Your
air cleaner periodically needs to be replaced.
Servicing Paper Filters
Paper filters cannot be cleaned and must be replaced
once a year or every 100 operating hours; more often if
used in extremely dusty conditions. Replacement
filters are available at a Authorized Tecumseh Servicing
Dealer. Follow the instructions next to the drawing of
your air cleaner to remove and replace it.
NOTE
DO NOT put oil on or clean paper filter.
