The air cleaner filter should be serviced every 50 hours,
and more frequently in extremely dusty conditions. The
filter element should be replaced every 200 hours.
1. Park machine on a level surface, lower cutting units,
stop engine, engage parking brake, and remove key
from the ignition switch. Unlatch and raise hood.
2. Release latches securing air cleaner cover to air
cleaner body. Separate cover from body. Clean inside of
air cleaner cover.
3. Gently slide filter out of air cleaner body to reduce the
amount of dust dislodged. Avoid knocking filter against

reuse a damaged filter.
IMPORTANT: Do not over service the air filter ele-
ment; damage may result.
5. Air filter can be cleaned either by washing or using
compressed air:
Washing Method
A. Prepare solution of filter cleaner and water. Soak
filter element about 15 minutes. Refer to directions
on filter cleaner carton for complete information.
B. After soaking filter for 15 minutes, rinse it with
clear water. Maximum water pressure must not ex-
ceed 40 psi to prevent damage to the filter element.
Rinse filter from clean side to dirty side.
C. Dry filter element using warm, flowing air (160
maximum), or allow element to air--dry. Do not use a
light bulb to dry the filter element because damage
could result.

Compressed Air Method
A. Blow compressed air from inside to the outside of
dry filter element. Do not exceed 100 psi to prevent
damage to the element.
B. Keep air hose nozzle at least 2 inches (5 cm) from
the filter. Move nozzle up and down while rotating the
filter element. Inspect for holes and tears by looking
through the filter toward a bright light.
6. If filter is being replaced, inspect new filter for ship-
ping damage. Check sealing end of filter. Do not install
a damaged filter.

body. Make sure filter is sealed properly by applying
