You may need to change the oil more often under dusty, dirty conditions.
ADD GASOLINE
NOTE: Before filling fuel tank, remove
and discard the debris plug that is inside the tank.
• Fill fuel tank. Use fresh, clean, regular
unleaded gasoline with a minimum of
87 octane. Do not mix oil with gaso-
line. Purchase fuel in quantities that
can be used within 30 days to assure
fuel freshness.
_WARNING:
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
enginewhile
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
additional information.
Never use engine
or carburetor cleaner products in the fuel

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 ovedoading 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.
• For side discharge lawn mowers,
cutting in a counter-clockwise direction,
starting at the outside of the area to be
cut, spreads grass clippings more
evenly and puts less load on the engine. To keep clippings off of
walkways, flower beds, etc., make the
flint cuts in a clockwise direction.
• Pores in cloth grass catchers can
"become filled with dirt and dust with
use end 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 MOWINGTIPS
IMPORTANT: For best performance, keep mower housing free of built-up grass and trash. See "Cleaning" in
MAINTENANCE section of this manua
• The special mulching blade will reel
the grass clippings many times and
reduce them in size so that as they f
onto the lawn they will disperse into
grass and not be noticed. Also, the
mulched grass will biodegrade quic to provide nutdents for the lawn.
Always mulch with your highest eng
(blade) speed as this will provide th,
best recurring action of the blades.
• Avoid cutting your lawn when it is w_
Wet grass tends to form clumps and
interferes with the mulching action, " best time to mow your lawn is the e_
afternoon. At this time the grass has
dried and the newly cut area will no1
exposed to the direct sun.
• For best results, adjust the lawn mo'
cutting height so that the lawn mowq
cuts off only the top one-third of the grass blades. If the lawn is overgrov will be necessary to raise the height cut to reduce pushing effort and to kq from overloading the engine and leaving clumps of mulched grass. F¢
extremely heavy mulching, reduce y width of cut by overlapping previous
cut path and mow slowly.
• Certain types of grass and grass
conditions may require that an area
mulched a second time to completel
hide the clippings.
When doing a
second cut, mow across or peq3end;
lar to the first cut path.
• Change your cutting pattem from w(
to week. Mow north to south one we then change to east to west the next week. This will help prevent matting and graining of the lawn.

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.
Immediately prepare your lawn mower for
storage at the end of the season or if the
unit will not be used for 30 days or more.
LAWN MOWER
When lawn mower is to be stored for a
period of time, clean it thoroughly, remove all dirt, grease, leaves, etc. Store in a clean, dry area,
1. Clean entire lawn mower (See
"CLEANING" in the Maintenance section of this manual).
2. Lubdcate as shown in the Maintenance section of this manual.
3. Be sure that all nuts, bolts, screws,
and pins are securely fastened.
Inspect moving parts for damage, breakage and wear. Replace if necessary.
4. Touch up all rusted or chipped paint
surfaces; sand lightly before painting.
HANDLE
You can fold your lawn mower handle for storage.
1. Squeeze the bottom ends of the lower handle toward each other until the lower handle clears the handle
bracket, then move handle forward.
2. Loosen upper handle mounting bolts
enough to allow upper handle to be
folded back.
IMPORTANT: When folding the handle
for storage or transportation, be sure to fold the handle as shown or you may
damage the control cables.
• When setting up your handle from the
storage position, the lower handle will
automatically lock into the mowing
position.

IMPORTANT:
It is important to prevent
gum deposits from forming in essential fuel system parts such as carburetor, fuel filter, fuel hose, or tank dudng 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.
1. Drain the fuel tank.
2. Start the engine and let it run until the fuel lines and carburetor are 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.
ENGINE OIL
Drain oil (with engine warm) and replace with clean engine oil. (See "ENGINE" in the Maintenance section of this manual).
CYLINDER
1. Remove spark plug.
2. Pour one ounce (29 ml) of oil through
spark plug hole into cylinder.
3. Pull starter handle slowly a few times to distribute oil.
4. 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 engone and exhaust areas are still warm.
A 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 storing in any enclosure.
