:Fit the felt prefilter (1) over the HD filter (2) - note correct installed position (see ilustration).

:Install HD filter (with felt prefilter) and carburetor box cover.

:Check carburetor setting and readjust if necessary.

The felt prefilter helps protect the HD filter and thus extends its useful life. For this reason the felt prefilter should be replaced at more frequent intervals than the HD filter.

Always replace a damaged filter.
