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 dent and other damage
which could possibly cause an air leak. Replace a
damaged air cleaner body.
3. Insure dust cap 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.

Servicing 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 one inch (25 mm) from the rubber baffle.
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. Loosen thumb screw until dust cup and baffle can be
removed (Fig. 29). Separate dust cup and baffle
(Fig. 29).
2. Dump dust out of the dust cup. After cleaning cup and
baffle, assemble and reinstall both parts.

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 (1200 hours) or annually, whichever comes
first.
1. Remove and service dust cup; refer to Servicing Dust
Cup and Baffle.
2. Remove wing nut w/gasket and slide filter element out
of air cleaner body (Fig. 29).
3. Clean the element by washing it in a solution of filter
cleaner (Toro Part No. 27-7220, available from Toro)
and water, or blow dirt out of filter by using compressed
air.
1. Thumb screw
2. Dust cup
3. Baffle
Important Do not remove plastic fin assembly
because back-blowing with compressed air removes
dust from beneath fins.
4. 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.
5. Keep air hose nozzle at least one 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.
6. Wipe inside of air cleaner body with a damp cloth to
remove excess dust. Slide filter into air cleaner body
and secure it in place with wing nut and gasket.
7. Reinstall dust cup and baffle. Move thumb screw
behind air cleaner body and tighten it securely.

Inspecting Filter Element

1. Place bright light inside filter.
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.
Replace filter if damage is evident.
