BEFORE STARTING ENGINE

TO START ENGINE

OIL

NOTE:
engine,
present
product
normal.

Your lawn mower is shipped without oil in the
engine.
• Be sure mower is level and area around oil
fill is clean.
• 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 fill.
• 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 oil more often under dusty,
dirty conditions.
ADD GASOLINE

Due to protective coatings on the
a small amount of smoke may be
during the initial use of the
and should be considered

• To start a cold engine, push primer three
(3) times before trying 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
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.
Gasoline filler

• Fill fuel tank. Use fresh, clean, regular
unleaded gasoline with a minimum of 87
octane. Do not mix oil with gasoline.
Purchase fuel in quantities that 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 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.
ACAUTION:
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.

MOWINGTIPS

MULCHING 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.
, 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.

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 and 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.
• 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.
• 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

thelawn.

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.

TO ADJUST HANDLE
The handle on your lawn mower has
three (3) height positions - adjust to height
that suits you.
• Squeeze the bottom ends of lower
handle towards each other until the pin
in handle can be inserted into one of
the three height adjustment holes.

The rear deflector, attached between the
rear wheels of your lawn mower, is
provided to minimize the possibility that
objects will be thrown out the rear of the
lawn mower into the operator's mowing
position.
If the rear deflector becomes damaged, it
should be replaced.

TO ASSEMBLE

GRASS

CATCHER

• Put grass catcher frame into grass bag
with rigid part of bag on the bottom.
Make sure the frame handle is outside
of the bag top.
• Slip vinyl bindings over frame.
NOTE: If vinyl bindings are too stiff, hold
them in warm water for a few minutes. If
bag gets wet, let it dry before using.
_CAUTION:
Do not run your lawn mower
without ctipping deflector or approved
grass catcher in place. Never attempt to
operate the lawn mower with the rear
door removed or propped open.

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 center 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-governed high speed needs
adjusting, contact your nearest authorized
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.

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

Operator Presence
Control Bar

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.
• 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, bolts, screws, and pins
are securely fastened. Inspect moving
parts 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
require manually locking into the
mowing position.
IMPORTANT:
When folding the handle for
storage or transportation, be sure to fold
the handle as shown or you may damage
the control cables.

ENGINE
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 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.

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.

TROUBLESHOOTING
PROBLEM
Does not start

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.
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.
