BEFORE STARTING ENGINE

OIL

Your lawn mower is shipped without oil in the

engine.

•Be sure mower is level and area around oil

fillis dean.

•Remove engine oil cap and fillto 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 oilto use, see "ENGINE' in

Maintenance section of this manual.

• Pour oilslowly. 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.

ADD GASOUNE

NOTE: Beforefillingfuel tank, removeand

discardthe debrisplugthat is insidethe tank.

•Fillfuel 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.

_]LCAUTION: 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.

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 startingan engine which has already

run for afew 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 primingsteps. 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

repeatp 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

inthe fast position.

•Pores in cloth grass catchers can become

tiltedwith 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 fallonto the

lawn they will disperse into the grass and

not be noticed. Also, the mulched grass will

biodegrade quicklyto provide nutrientsfor

the lawn. Always mulch with your highest

engine (blade) speed as this will provide

the best recuttingactionof 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,adjustthe 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 firstcut path.

•Change your cutting pattern from week to

week. Mow northto south one week then

change to east to westthe next week. This

wilt help prevent matting and graining of

the lawn.

with API service classification SF, SH or

SG. Select the oil's SAE viscosity grade

according to your expected operating

tem

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.

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.

an authorized service canter for repair or

adjustment.

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.

Your engine speed has been factoryset. Do

not attempt to increase engine speed or it

may result in personal injury. If you believe

LAWNMOWER

When lawn mower is to be stored for a period

oftime, clean it thoroughly, remove all did,

grease, leaves, etc. Store in a clean, dry area.

•Clean entire lawn mower (See "CLEAN-

ING" 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.

Replaceit necessary.

•Touch up all rusted or chipped paint

surfaces; sand lightlybefore painting.

HANDLE

You can fold your lawn mower handle for

storage.

•Squeeze the bottom ends of the lower

handle toward each other until the

lower handle clears the handle bracket,

then move handle forward.

•Loosen upper handle mounting bolts

enough to allow upper handle to be

folded back.

FUEL SYSTEM

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.

ENGINEOIL

Drain oil (with engine warm) and replace

with clean engine oil. (See "ENGINE' ,n

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 _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 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

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.
