Installation Instructions
Servicing Air Cleaner
General Air Cleaner Maintenance
To prevent possible severe engine damage and ensure
maximum engine service life, periodically inspect the
air cleaner and hose assembly.
1. Assure hose between air cleaner and carburetor
is clamped securely in place. Replace the hose if
it is cracked or punctured.
2. Check air cleaner body for dents and other
damage which could possibly cause an air leak.
Replace a damaged air cleaner body.
3. Insure dust cup is sealing around bottom of air
cleaner body.
4. Mounting screws and nuts holding air cleaner in
place must be tight.
5. Inlet cap must be free of obstructions.
Service Dust Cup and Baffle
Inspect the dust cup and rubber baffle once a week or
every 50 hours operation; however, daily or more
frequent inspection is required when operating
conditions are extremely dusty and dirty. Never allow
dust to build up closer than 1 inch ( 25 mm) from the
slot in top of dust cup.
Note: If conditions are extremely dusty and
dirty, begin by checking dust cup and
baffle after each day’s operation to
establish approximately how long an
interval passes before dust cup should
be emptied. Base further maintenance
requirements on this figure. These
conditions may be particularly
prevalent if the rear discharge cutting
unit is attached.
1. Disengage the power take off (PTO), set the
parking brake, and turn the ignition key to
“OFF” to stop the engine. Remove the key.
2. Loosen thumb screw until dust cup and baffle
can be removed. Separate dust cup and baffle
(Fig. 4).
3. Dump dirt out of the dust cup. After cleaning
cup and baffle, reinstall both parts with TOP of
dust cup up (Fig. 4).

Installation Instructions
Servicing Air Cleaner Filter
Service the air cleaner filter every 200 hours or more
frequently in extreme dusty or dirty conditions by
washing or using compressed air. Replace the element
after every six cleanings (1500 hours) or annually,
whichever comes first.
Note: If conditions are extremely dusty and
dirty, begin by checking dust cup and
baffle after each day’s operation to
establish approximately how long an
interval passes before dust cup should
be emptied.
1. Disengage the power take off (PTO), set the
parking brake, and turn the ignition key to
“OFF” to stop the engine. Remove the key.
2. Clean around the air cleaner to prevent dirt from
getting into the engine and causing damage.
3. Remove and service dust cup; refer to Service
Dust Cup and Baffle.
Inspecting Filter Element
1. Place bright light inside filter element.
2. Rotate filter slowly while checking for
cleanliness, ruptures, holes, and tears. Replace
defective filter element.
3. Check fin assembly, gasket, and screen for
damage.
Cleaning the Filter Element – Washing
Method 1
IMPORTANT: Replace filter if damage is
evident.
1. Clean filter element by washing in a solution of
filter cleaner (Toro Part No. 27-7220, available
from Toro) and water.
IMPORTANT: Do not remove plastic fin
assembly because washing removes dust from
beneath fins.
4. Remove wing nut w/gasket and slide filter
element out of air cleaner body (Fig. 4).
2. Prepare a solution of filter cleaner and water and
soak filter element about 15 minutes. Refer to
directions on filter cleaner carton for complete
information.
3. After soaking filter for 15 minutes, rinse with
clear water. Maximum water pressure must not
exceed 40 psi (276 kPa) to prevent damage to
the filter element.
4. Dry filter element using warm, flowing air
(160F (71C) max), or allow element to
air–dry. Do not use compressed air or a light
bulb to dry the filter element because damage
could result.

Installation Instructions
Cleaning the Filter Element –
Compressed Air Method
IMPORTANT: Replace filter if damage is
evident.
Note: Compressed air is recommended when
element must be used immediately
after servicing because a washed
element must be dried before it is used.
By comparison, washing the element
cleans better than blowing dirt out with
compressed air.
IMPORTANT: Do not remove plastic fin
assembly because back-blowing with
compressed air removes dust from beneath
fins.
1. Blow compressed air from inside to the outside
of dry filter element. Do not exceed 100 psi
(689 kPa) to prevent damage to the element.
2. Keep air hose nozzle at least 1 inch (25 mm)
from pleated paper, and move nozzle up and
down while rotating the filter element. Inspect
element when dust and dirt are removed; refer to
Inspecting Filter Element.
3. Wipe inside of air cleaner body with a damp
cloth to remove excess dust. Slide filter into air
cleaner body and secure in place with wing nut
and gasket.
4. Install dust cup and baffle. Move thumb screw
behind air cleaner body and tighten it securely.
