BEFORE STARTING ENGINE
OIL
Your lawn mower is shipped without oil in the
engine.
• Be sure mower is level and area around oil
fill is dean.
• Remove engine oil cap and fill to the full
line on the dipstick.
NOTE: Allow oil to settle down into
engine for accurate dipstick reading.
• Engine holds 20 ozs. of oil. For type and
grade of oil to use, see "ENGINE' in
Maintenance section of this manual.
• Pour oil slowly. Do not over till.
• Check oil level before each use. Add oil if
needed. Fill to full line on dipstick.
• To read proper level, tighten engine oil cap
each time.
• Reinstall engine oil cap and tighten.
• Change the oil after every 25 hours of
operation or each season. You may need
to change the ell more often under dusty,
dirty cond'fdons.

NOTE: Beforefillingfuel tank, removeand
discardthe debrisplugthat is inside the tank.
• Fill fuel tank. Use fresh, clean, regular
unleaded gasoline with a minimum of 87
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 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 fuel tank, start the
engine and let it run until 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 fuel tank
or permanent damage may occur.

TO START ENGINE
• To start a cold engine, push primer three
(3) times before t_ing to start. Use a firm
push. This step is not usually necessary
when starting an engine which has already
run for a few minutes.
• Hold operator presence control bar down
to the handle and pull starter handle
quickly. Do not allow starter rope to snap
back.
• To stop engine, release operator presence
control bar.
NOTE: In cooler weather it may be necessary
to repeat priming steps. In wanner weather
over priming may cause flooding and engine
will not start. If you do flood engine, wait a few
minutes before attempting to start and do not

repeat
p mingsteps.

MOWINGTIPS
• Under certain conditions, such as very tall
grass, it may be necessary to raise the
height of cut to reduce push;_geffort and to
keep from overloading the engine end
leaving clumps of grass clippings. It may
also be necessary to reduce ground speed
end/or run the lawn mower over the area a
second time.
• FoPextremely 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.
• Pores in cloth grass catchers can become
tilted with dirt and dust with use and
catchers will collect less grass. To prevent
this, regularly hose catcher off with water
end 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 recut the
grass clippings many times and reduce
them in size so that as they fall onto the
lawn they will 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 dried and the newly
cut area will not be exposed to the direct
sun.

• For best results, adjust the lawn mower
cutting height so that the lawn mower cuts
off only the top one-third of the grass
blades. If the lawn is overgrown it will be
necessary to raise the height of cut to
reduce pushing effort end to keep from
overloading the engine and leaving
clumps of mulched grass. For extremely
heavy mulching, reduce your width of cut,
mow slowly and raise the rear of the lawn
mower one wheel adjuster setting higher
than the front.
• Certaintypesofgrassand grassconditione
may require that an area be mulched a
second time to completely hide the

clippings.
Whendoinga secondcut,mow
across or perpendicular to the first cut path.
• Change your cutting pattern from week to
week. Mow north to south one week then
change to east to west the next week. This
wilt help prevent matting and graining of
the lawn.

wear. If catcher needs replacing, replace
only with a manufacturer approved
replacement catcher. Give the lawn mower
model number when ordering.
ENGINE

NOTE: Although multi--viscosity oils
(5W30, 10W30 etc.) improve starting in
cold weather, these muiti--vlacosity
oils
will result in increased oil consumption
when used above 32°F. Check your
engine oil level more frequently to avoid
possible engine damage from running
low on oil.
Change the oil after every 25 hours of
operation or at least once a year if the
lawn mower is not used for 25 hours in
one year.
Check the crankcase oil level before
starting the engine and after each five (5)
hours of continuous use. Tighten oil plug
securely each time you check the oil level.

LAWNMOWER
When lawn mower is to be stored for a period
of time, clean it thoroughly, remove all did,
grease, leaves, etc. Store in a clean, dry area.
• Clean entire lawn mower (See "CLEANING" in the Maintenance section of this
manual).
• Lubricate as shown in the Maintenance
section of this manual.
• Be sure that all nuts, belts, screws, and pins
are securely fastened. Ir_0ect moving
parts for damage, breakage and wear.

ENGINE
CARBURETOR
Your carburetor has a non-adjustable fixed
main jet for mixture control. If your engine
does not operate properly due to suspected
carburetor problems, take your lawn mower to
an authorized service canter for repair or
adjustment.
IMPORTANT: Never tamper with the engine
governor, which is factory set for proper
engine speed. Overspeeding the engine
above the factory high speed setting can be
dangerous, if you think the engine-govemed
high speed needs adjusting, contact your
nearest authorized service canter, which has
proper equipment and experience to make
any necessary adjustments.
ENGINE SPEED
Your engine speed has been factory set. Do
not attempt to increase engine speed or it
may result in personal injury. If you believe
that the engine is runningtoo fast or too slow,
take your lawn mower to an authorized
service canter for repair and adjustmerrL

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.

ENGINEOIL
Drain oil (with engine warm) and replace
with clean engine oil. (See "ENGINE' ,n
the Maintenance section of this manual).
CYLINDER

IMPORTANT:
It is important to prevent
_luUmdeposits from forming in essential
el 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.
• 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.

TROUBLESHOOTING
PROBLEM
Does not start

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 _lasoline 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 protective 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.

Never cover mower while
engine and exhaust areas are still warm.
ACAUTION:

where fumes may reach an open flame or
spark. Allow the engine to cool before
