Service the air cleaner filter every 100 hours or more
frequently in extreme dusty or dirty conditions by
washing or using compressed air. Replace the element
after every (5) cleanings (500 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.
Clean the element by washing it in a solution of
filter cleaner (Toro Part No. 27Ć7220) and water, or blow
dirt out of filter by using compressed air.
04' 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
!! Do not remove plastic fin assembly
because washing removes dust from beneath fins.
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.
After soaking filter for 15 minutes, rinse it with
clear water. Maximum water pressure must not
exceed 40 psi to prevent damage to the filter
element.
Dry filter element using warm, flowing air
(160F 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.
Compressed Air Method
!! Do not remove plastic fin assembly
because back-blowing with compressed air removes
dust from beneath fins.
Blow compressed air from inside to the outside
of dry filter element. Do not exceed 100 psi to
prevent damage to the element.
Keep air hose nozzle at least one inch 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.
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.
Reinstall dust cup and baffle. Move thumb screw
behind air cleaner body and tighten it securely.

Replace spark plugs or reset gap after every 200
operating hours to assure proper engine performance
and reduce exhaust emission level.
Correct spark plug to use is a Champion RC 12YC or
equivalent.
Recommended air gap is .040".
04' The spark plug usually lasts a long time;
however, the plug should be removed and checked
whenever the engine malfunctions.
Clean area around spark plugs so foreign matter
cannot fall into cylinder when spark plug is removed.
. Pull spark plug wires off spark plugs and remove
plugs from cylinder head.
Check condition of side electrode, center
electrode, and center electrode insulator to assure
there is no damage.
