HOW TO SERVICE THE AIR FILTER
NOTE: Never run the engine with the air filters (air cleaner
cartridge, pre-cleaner) removed. The air filters will help protect
the engine against wear. For the correct replacement filter, see
the parts list for the engine.
CAUTION: Do not use pressurized air or solvents to clean
cartridge. Pressurized air can damage cartridge; solvents will
dissolve cartridge.
If a filter is stamped WASHABLE, it can be washed with warm water
and mild soap.
IMPORTANT: Rinse in tap water with SCREENside up allowing
dirt and debris to filter out. Leave filter to dry overnight before
reinstalling.

dle toward the engine (Figure 25).
2. Remove the cover.
3. Carefully lift the air cleaner cartridge, and the pre-cleaner, if
equipped, from the blower housing.
4. To prevent debris from failing into the carburetor, carefully clean
the air cleaner base.
5. install a new pre-cleaner, if equipped, and air cleaner car-
tridge firmly into the air cleaner base.
6. Align the tabs on the cover with the slots on the blower hous-
ing and install the cover.
