• Dress properly. Do not operate mower
when barefoot or wearing open sandals.
Wear only solid shoes with good traction
when mowing.
• Check fuel tank before starting engine.
Do not fill gas tank indoors, when the
engine is running or when the engine is
hot. Allow the engine to cool for several
minutes before filling the gas tank. Clean
off any spilled gasoline before starting
the engine.
• Always make wheel height adjustments
before starting your mower. Never
attempt to do this while the engine is
running.
• Mow only in daylight or good artificial
light.
OPERATION:
• Keep your eyes and mind on your
mower and the area being cut. Do not let
other interests distract you.
• Do not mow wet or slippery grass. Never
run while operating your mower. Always
be sure of your footing — keep a firm
hold on the handles and walk.
• Do not put hands or feet near or under
rotating parts. Keep clear of the dis-
charge opening at all times.
• Always stop the engine whenever you
leave or are not using your mower, or
before crossing driveways, walks, roads,
and any gravel—covered areas.
• Never direct discharge of material
toward bystanders nor allow anyone
near the mower while you are operating
it.
• Before cleaning, inspecting, or repairing
your mower, stop the engine and make
absolutely sure the blade and all moving
parts have stopped. Then disconnect the
spark plug wire and keep it away from
the spark plug to prevent accidental
starting.
• Do not continue to run your mower if you
hit a foreign object. Follow the procedure
outlined above, then repair any damage
before restarting and operating you
mower.
• Do not change the governor settings or
overspeed the engine. Engine damage
or personal injury may result.
• Do not operate your mower if it vibrates
abnormally. Excessive vibration is an
indication of damage; stop the engine,
safely check for the cause of vibration
and repair as required.
• Do not run the engine indoors. Exhaust
fumes are dangerous.
• Never cut grass by pulling the mower
towards you. Mow across the face of
slopes, never up and down or you
might lose your footing. Do not mow
excessively steep slopes. Use caution
when operating the mower on uneven
terrain or when changing directions —
maintain good footing.
• Never operate your mower without
proper guards, plates, grass catcher or
other safety devices in place.
MAINTENANCE AND STORAGE:
• Check the blade and the engine
mounting bolts often to be sure they are
tightened properly.
• Check all bolts, nuts and screws at
frequent intervals for proper tightness to
be sure mower is in safe working
condition.
• Keep all safety devices in place and
working.
• To reduce fire hazard, keep the engine
free of grass, leaves or excessive
grease and oil.
• Check grass catcher often for deteriora-
tion and wear and replace worn bags.
Use only replacement bags that are
recommended by and comply with
specifications of the manufacturer of
your mower.
• Always keep a sharp blade on your
mower.
• Allow engine to cool before storing in
any enclosure.
• Never store mower with fuel in the tank
inside a building where fumes may
reach an open flame or an ignition
source such as a hot water heater,
space heater, clothes dryer, etc.
Look for this symbol to point out
important safety precautions. It means
CAUTION!!! BECOME ALERT!!! YOUR
SAFETY IS INVOLVED.
CAUTION: Always disconnect spark
plug wire and place wire where it cannot
contact spark plug in order to prevent
accidental starting when setting up,
transporting, adjusting or making repairs.

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
warmer 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 priming steps.
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 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
additional information. Never use engine
or carburetor cleaner products in the fuel
tank or permanent damage may occur.
CAUTION: Fill to bottom of gas tank
filler neck. Do not overfill. Wipe off any
spilled oil or fuel. Do not store, spill or
use gasoline near an open flame.

MULCHING MOWING TIPS
IMPORTANT: For best 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 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 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.
Max 1/3
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 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.
• 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.
• Certain types of grass and grass condi-
tions 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.
• Change your cutting pattern 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.

TO SHARPEN BLADE
NOTE: We do not recommend sharpen-
ing blade - but if you do, be sure the blade
is balanced.
Care should be taken to keep the blade
balanced. An unbalanced blade will
cause eventual damage to lawn mower or
engine.
• The blade can be sharpened with a file
or on a grinding wheel. Do not attempt
to sharpen while on the mower.
• To check blade balance, drive a nail
into a beam or wall. Leave about one
inch of the straight nail exposed. Place
center hole of blade over the head of
the nail. If blade is balanced, it should
remain in a horizontal position. If either
end of the blade moves downward,
sharpen the heavy end until the blade
is balanced.
GRASS CATCHER
• The grass catcher may be hosed with
water, but must be dry when used.
• Check your grass catcher often for
damage or deterioration. Through normal
use it will wear. If catcher needs replacing,
replace only with a manufacturer approved
replacement catcher. Give the lawn
mower model number when ordering.
NOTE: Although multi-viscosity oils
(5W30, 10W30 etc.) improve starting in
cold weather, these multi-viscosity 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.
TO CHANGE ENGINE OIL
NOTE: Before tipping lawn mower to
drain oil, drain fuel tank by running
engine until fuel tank is empty.
• Disconnect spark plug wire from spark
plug and place wire where it cannot come
in contact with spark plug.
• Remove engine oil cap; lay aside on a
clean surface.
• Tip lawn mower on its side as shown and
drain oil into a suitable container. Rock
lawn mower back and forth to remove any
oil trapped inside of engine.
• Wipe off any spilled oil on lawn mower and
on side of engine.
• Fill engine with oil. Fill only to the "FULL"
line on the dipstick. DO NOT overfill.
• Replace engine oil cap.
• Reconnect spark plug wire to spark plug.
14
• 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.
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 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.
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 storing in any enclosure.

CLEANING
IMPORTANT: For best performance,
keep mower housing free of built-up
grass and trash. Clean the underside of
your mower after each use.
CAUTION: Disconnect spark plug wire
from spark plug and place wire where it
cannot come in contact with the spark
plug.
• Turn lawn mower on its side. Make sure air
filter and carburetor are up. Clean the
underside of your lawn mower by scraping
to remove build-up of grass and trash.
• Clean engine often to keep trash from
accumulating. A clogged engine runs
hotter and shortens engine life.
• Keep finished surfaces and wheels free of
all gasoline, oil,etc.
• We do not recommend using a garden
hose to clean lawn mower unless the
electrical system, muffler, air filter and
carburetor are covered to keep water out.
Water in engine can result in shortened
engine life.
SERVICE AND ADJUSTMENTS
CAUTION: Before performing any
service and adjustments:
• Release control bar and stop engine.
• Make sure the blade and all moving
parts have completely stopped.
• Disconnect spark plug wire from spark
plug and place where it cannot come
in contact with plug.

FUEL SYSTEM
IMPORTANT: It is important to prevent gum
deposits from forming in essential fuel system
parts such as carburetor, f 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.
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
center for repair and/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-governed high speed needs
adjusting, contact your nearest authorzed
service center, 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 running too fast
or too slow, take your lawn mower to an
authorized service center for repair and
adjustment.
