GAS
• Fill fuel tank. Use fresh, clean, regular
unteaded gasoline with a minimum of 87
octane. Do not mix oil with gasoline.
Purchase fuel in quantities thatcan be used
within 30 days to assure fuel freshness.
IMPORTANT: When operating in
temperaturesbelow 32°F(0°C), use fresh,
clean winter grade gasofine to help insure
good cold weather starting.
WARNING: Experience indicatesthat alcohol
blended fuels (called gasohol or using ethanol
or methano0 can attract moisture which leads
to separation and formation of acids during
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 next season. See
Storage Instructions for additiona_ information,
Never use engine or carburetor' cleaner
products in the fuel tank or permanent
damage may occur:

MOWING TIPS
° 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 overloadingthe engine and
!eaving clumps of grass clippings.
o For extremely heavy cutting, reduce the
width of cut and raise the rear of the lawn
mower housing one (1) wheel adjuster
setting higher than the front for better
discharge of grass°
= 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, heaw/grass, clumps of cut grass
may not enter the grass catchen Reduce
ground speed (pushing speed) and!or run
the lawn mower over the area a second
time°
o If a trail of grass clippings is left on the right
side of a rear discharge lawn mower, mow
in a clockwise direction with a small overlap
to collect the clippings on the next pass.
- Keep top ofengine around starter clear and
clean of grass clippings and chaff..This will
help engine air flow and extend engine life,
° 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 catchers off with water
and let dry before using.
Max,, 1/3
MULCHING MOWING TIPS
IMPORTANT: Forbest performance, keep
mower housing free of built-up grass and
trash° See "Cleaning" in MAINTENANCE
section of this manual°
° The special mulching blade will recut the
grass clippings many times and reduce
them in size so that as they fall onto the
lawn they wil! disperse into the grass and
not be noticed. Also, the mulched grass will
biodegrade quickly to provide nutrients for
the lawn. Always mulch with your highest
engine (blade) speed as this will provide the
best recutting action of the blades.
,, Avoid cutting your lawn when it is wet. Wet
grass tends to form clumps and interferes
with the mulching action. The best time to
mow your lawn is the early afternoon At this
time the grass has dded and the newly cut
area will not be exposed to the direct sun.
o For best results, adjust the lawn mower
cutting height so that the lawn mower cuts
off only the top one4hird of the grass blades.
If the lawn is overgrown itwill be necessary
to raise the height of cut 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 by overlapping
previously cut path and mow slowly_
• Certain types of grass and grass conditions
may require that an area be mulched a
second time to completely hide the
clippings.. When doing a second cut, mow
across or perpendicular to the first cut path.,
o Change your cutting pattem from week to
week. Mow north to south one week then
change to east to west the next week. This
will help prevent matting and graining of the
lawn.

engine above the factory high speed
setting can be dangerous, if you think the
engine-governed high speed needs
adjusting, contact your nearest
AUTHORIZED service center, which has
proper equipment and experience to make
any necessary adjustments.

ENGINE
FUEL SYSTEM
IMPORTANT: It is important to prevent
gumdeposits 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 an engine while in storage.
•Drain the fuel tank.
=Start the engine and let it run until the
fuel lines and carburetor are empty,
o 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 carbure-
tor. Do not drain the gas tank and
carburetor if using fuel stabilizer.
ENGINE OIL
Drain oil (with engine warm)and replace
with clean engine oil, (See "ENGINE" in
the Customer' Responsibilities section of
this manual).
CYLINDER
° Remove spark plug.
= Pour one ounce (29 ml) of oil through
spark plug hole into cylinder.
o Pull starter handle slowly a few times to
distribute oil.
° Replace with new spark plug.

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 protective
cover that does not retain moisture_ Do

will cause your unit to rust,
IMPORTANT: Never cover mower while
engine and exhaust areas are still warm.
CAUTION: 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
