General Air Cleaner Maintenance; Servicing Dust Cup And Baffle; Servicing Air Cleaner Filter - Toro 30789 Operator's Manual

General Air Cleaner
Maintenance
Inspect air cleaner and hose periodically to maintain
maximum engine protection and to ensure maximum
service life.
Assure hose between air cleaner and carburetor is
clamped securely in place. Replace the hose if it is
cracked or punctured.
Check air cleaner body for dents and other damage
which could possibly cause an air leak. Replace a
damaged air cleaner body.
Be sure dust cap is sealing around bottom of air cleaner
body.
Mounting screws and nuts holding air cleaner in place
must be tight.
Inlet cap must be free of obstruction.

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. 27). Separate dust cup and baffle
(Fig. 27).
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 250 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.
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. 28).

3. Clean the element by washing it in a solution of filter
cleaner ( Toro Part No. 27-7220) and water, or blow dirt
out of filter by using compressed air.
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. Remember, though, filter must be
washed when exhaust soot is lodged in the filter pores.
Washing Method
Important Do not remove plastic fin assembly
because back–blowing with compressed air removes
dust from beneath fins.
