AIR FILTER INSPECTION

Remove the air cleaner cover and inspect the filter.
Use caution to avoid dropping debris into the air passage.
Always replace damaged filter elements.

AIR FILTER SERVICE

A dirty air filter will restrict air flow to the carburetor, which will reduce engine
performance. When an air filter becomes dirty, replace it immediately.
Operating the engine without an air filter or with a damaged air filter will allow dirt to enter
the engine, causing the engine to wear rapidly. This type of damage is not covered by the
Limited Warranty.
