To prevent possible severe engine damage and ensure
maximum engine service life, periodically inspect the
air cleaner and hose assembly.
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 dent and other damage
which could possibly cause an air leak. Replace a
damaged air cleaner body.
Insure 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 obstructions.
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.
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.
Loosen thumb screw until dust cup and baffle can
be removed (Fig. 30). Separate dust cup and baffle
(Fig. 30).
Dump dust out of the dust cup. After cleaning cup
and baffle, assemble and reinstall both parts.
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.
Remove and service dust cup; refer to Servicing
Dust Cup and Baffle.
Remove wing nut w/gasket and slide filter element
out of air cleaner body (Fig. 30).
