octane. Do not mix oil with gasoline.
Purchase fuel in quantitiesthat can be
used within 30 days to assure fuel
freshness.
AWARNING: Experience indicates that
alcohol blended fuels (called gasohol or
using ethanol or methanol) can attract
moisture which leads to separation and
formation of acids dudng storage. Acidic
gas can damage the fuel system of an
engine while in storage• To avoid engine
problems, the fuel system should be
emptied before storage of 30 days or
longer• Drain the gas tank, start the
engine and let it run until the fuel lines
and carburetor are empty. Use fresh fuel

MOWlNGTIPS
* Under certain conditions, such as very
tall grass, it may be necessary to raise
the height of cut to reduce pushing
effort and to keep from overloading the
engine and leaving clumps of grass
clippings. It may also be necessary to
reduce ground speed and/or run the
lawn mower over the area a second
time.
• For extremely heavy cutting, reduce the
width of cut by overlapping previously
cut path and mow slowly.
• For better grass bagging and most
cutting conditions, the engine speed
should be set in the fast position.
• When using a rear discharge lawn
mower in moist, heavy grass, clumps of
cut grass may not enter the grass
catcher. Reduce ground speed
(pushing speed) and/or run the lawn
mower over the area a second time.
• If a trail of clippings is left on the right
side of a rear discharge mower, mow in
a clockwise direction with a small
overlap to collect the clippings on the
next pass.
• Pores in cloth grass Catchers can
become filled with dirt and dust with use
and catchers will collect less grass. To
prevent this, regularly hose catcher off
with water and let dry before using.
• Keep top of engine around starter clear
and clean of grass clippings and chaff.
This.will help engine air flow and
extend engine life.
MULCHING MOWING TIPS
IMPORTANT: For best performance, keep
mower housing free of built-up grass and
trash. Clean UNDERSIDE OF MOWER
HOUSING after each use. See "Cleaning"
in MAINTENANCE section of this manual.
• The special mulching blade will recurthe
grass clippings many times and reduce
them in size so thatas they fallonto the
lawn they will disperse into the grass and
notbe noticed. Aiso,the mulched grass will
biodegrade quicklyto provide nutrientsfor
the lawn. Always mulch withyour highest
engine (blade) speed as this will provide
the best recuttingaction of the blades.
• Avoid cuttingyour lawn when itis w_ Wet
grass tends to form dumps and interferes
with the muk:_ action. The best time to
mow your lawn is the early afternoon.At
this time the grass has dried and the newly
cut area will not be exposed to the direct
sun.
• For best results, adjustthe lawn mower
cuttingheightso thatthe lawn mower cuts
off onlythe top one-thirdof the grass
blades. Ifthe lawn is overgrown itwill be
necessary to raise the height ofcut to
reduce pushing effort and to keep from
overloading the engine and leaving
clumps of mulched grass. For extremely
heavy mulching,reduce your width of cut,
mow slowlyand raise the rear of the lawn
mower one wheel adjuster setting higher
than the front.
• Certain types of grass and grsss conditions
may requirethat an area be mulched a

grease, leaves, etc. Store in a clean, dry area.
• Clean entire lawn mower (See "CLEAN-
ING" in the Maintenance section of this
manual).
• Lubricate as shown in the Maintenance
section of this manual.
• Be sure that all nuts, bolts, screws, and pins
are securely fastened. Inspect moving
pads for damage, breakage and wear.
Replace if necessary.
• Touch up all rusted or chipped paint
surfaces; sand lightly before painting.
HANDLE
• You can fold your lawn mower handle
for storage.
• Loosen the two (2) handle knobs on
sides of the upper handle and allow
handle to fold down to the rear.
• Squeeze the bottom ends of lower
handle toward each other until pins in
handle clear the brackets and pivot
entire handle assembly forward and
allow it to rest on mower.
• When setting up your handle from the
storage position, the lower handle will

FUEL SYSTEM
IMPORTANT: It is important to prevent
gum deposits from forming in essential
fuel system parts such as carburetor, fuel
filter, fuel hose, or tank during storage.
Also, experience indicates that alcohol
blended fuels (called gasohol or using
ethanol or methanol) can attract moisture
which leads to separation and formation
of acids during storage. Acidic gas can
damage the fuel system of anengine
while in storage.
• Drainthefueltank.
Startthe engine and letitrun untilthe
fuellinesand carburetorare empty.
Never use engine or carburetor cleaner
products in the fuel tank or permanent
damage may occur.
• Use fresh fuel next season.
NOTE: Fuel stabilizer is an acceptable
alternative in minimizing the formation of
fuel gum deposits during storage. Add
stabilizer to gasoline in fuel tank or
storage container. Always follow the mix
ratio found on stabilizer container. Run
engine at least 10 minutes after adding
stabilizer to allow the stabilizer to reach
the carburetor. Do not drain the gas tank
and carburetor if using fuel stabilizer.
15
ENGINE OIL
Drain oil (with engine warm) and replace
with clean engine oil. (See "ENGINE" in
the Maintenance section of this manual).
CYLINDER
• Remove spark plug.
• Pour one ounce (29 ml) of oil through
spark plug hole into cylinder.
• Pull starter handle slowly a few times to
distribute oil.
• Replace with new spark plug.
OTHER
• Do not store gasoline from one season
to another.
• Replace your gasoline can if your can
starts to rust. Rust and/or dirt in your
gasoline will cause problems.
• If possible, store your unit indoors and
cover it to give protection from dust and
dirt.
• Cover your unit with a suitable protec-
tive cover that does not retain moisture.
Do not use plastic. Plastic cannot
breathe which allows condensation to
form and will cause your unit to rust.
IMPORTANT: Never cover mower while
engine and exhaust areas are still warm.
ACAUTION: Never store the lawn mower
with gasoline in the tank inside a building
where fumes may reach an open flame or
spark. Allow the engine to cool before
storing in any enclosure.
