Your engine will not run properly and may be damaged if you
run it with a dirty air cleaner. Clean or replace more often if
operating under dusty or dirty conditions.
NOTICE Do not use pressurized air or solvents to clean the
filter. Pressurized air can damage the filter and solvents will
dissolve the filter.
To service the air cleaner, follow these steps:
1. Loosen knobs and remove cover. Remove air cleaner by
lifting the ends up and out.
2. To loosen debris, gently tap air cleaner on a hard
surface. If air cleaner is excessively dirty, replace with a
new air cleaner.
3. Install clean (or new) air cleaner inside base and push
down until air cleaner snaps in place. See Specifications.
4. Reinstall cover and tighten knobs.
