ANTHCING RAFFLE
Some engines may be equipped with an anti-icing air cleaner feature

to enable the engine to runat temperatures below 32OF(0°C), without
ice forming in the carburetor.

Ifso equipped, the air cleaner base will have an opening which draws
warm air from the muffler into the air cleaner housing. To work
effectively, it is necessary to block cold air from entering the air

cleaner.
IN TEMPERATURES 32°F (0°C) AND BELOW: (See figure 6)

1. Remove wing nut from air cleaner cover.

2. Remove aircleaner cover from base.

3. Remove red baffle from inside of air cleaner cover,

4. insert red baffle in "winter" position shown.

IN TEMPERATURES ABOVE 32OF(0oC):

Fellow above directions, removing baffle from "winter" position and

reinstalling in "summer" position.

CLEANER INSTALLED ON ENGINE.

Clean and re-oil every three (3) months or every 25 operating
hours. Clean and re-oildaily ifused inextremelydustyconditions.
