extremely dusty conditions. Replacement filters are

E. Anti-Icing Baffle
Some engines may be equipped with an anti-icing air
cleaner baffle that prevents ice from forming in the
carburetor when the engine is run at temperatures below
32°F (0°C).
Engines equipped with the baffle will have an opening
which draws warm air from the muffler into the air cleaner
housing. To work effectively, it is necessary for the baffle to
block cold air from entering the air cleaner.
At temperatures of 32°F (0°C) and Below
1. Remove wing nut from air cleaner cover. See Figure 25.
2. Remove air cleaner cover from base.
3. Remove red baffle from inside of air cleaner cover.
