BEFORE STARTING ENGINE

OIL

Your lawn mower is shipped without oil in the

engine.

•Be sure mower is level and area around oil

flUis dean.

•Remove engine oilcap and fillto the full

line on the d_

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 oilcap

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

•Fillfuel tank. Use fresh, clean, regular

unleaded gasoline with a minimum of 87

octane. Do not mix oilwith gasoline.

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 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.

MOWlNGTIPS

•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.

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 ontothe

lawn they wgldisperse into the grass and

not be noticed. Also, the mulched grass will

biodegrade quicldyto 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 mulchingaction, The best time to

mow your lawn is the early aftemoon. At

this time the grass has dried and the newly

cut area will not be exposed to the _rect

sun.

•For best results,adjust the lawn mower

cutting height so that the lawn mower cuts

off onlythe 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 effortand to keep from

overloading the engine and leaving

dumps of mulched grass. For extremely

heavy mulching, reduce your width of cut,

mow slowlyand raise the rear of the lawn

mower one wheel adjuster setting higher

than tbe fronL

•Certain types of grass and grsss conditions

may require that an area be mulched a

second time to completely hide the

d_W_ngs.Wh_ ddng asoco_ c_ mow

• Change your cuttingpattern from week to

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 center for repair and adjustment.

Immediately prepare your lawn mower for

storage at the end of the season or if the unit

willnot be used for 30 days or more.

LAWN MOWER

When lawn mower is to be stored for a period

of time, dean it thoroughly,remove all dirt,

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

• Clean entire lawn mower (See "CLEAN-

ING" inthe 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. Inspect moving

parts for damage, breakage and wear.

Replace if 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.

IMPORTANT: When folding the handle

for storage or transportationg, 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. Lower handle

FUEL SYSTEM

IMPORTANT: It is important to prevent

gum deposits trom 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 end 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

altemative 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 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.

_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.
