Service Interval: Before each use or daily—Inspect the
air-cleaner elements.
Every 50 hours—Clean the air-cleaner elements. Clean
them more frequently in dusty operating conditions.
Every 300 hours/Yearly (whichever comes
first)—Replace the paper air-cleaner element. Replace
it more frequently in dusty operating conditions.
Important: Do not operate the engine without the
air-filter assembly; extreme engine damage will occur.

if they are damaged or excessively dirty.

Note: Never try to brush dirt off the paper element;
brushing forces the dirt into the fibers.

nonflammable solvent.
Note: Do not use fuel to clean the foam element
because it could create a risk of fire or explosion.
