BEFORE STARTING ENGINE

OIL

Your lawn mower is shipped without oil in the

engine.

•Be sure mower is level and area around oil

flitis clean.

•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 fill

• Check oil level before each use. AdO oil if

needed. Fill to full line on dipstick.

•To read proper level, tighten engine oHcap

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 conci'dons.

GAS

NOTE: Before filling fuel tank, remove

and discard the debris plug that is inside

the tank.

•Fillfuel tank. Use fresh, clean, regular

unleaded gasoline with a minimum of 87

octane. Do not mix oHwith gasoline.

Purchase fuel in quantitiesthat can be

used within 30 days to assure fuel

AIN_d_I41NG: Experience indicates that

alcohol blended fuels (called gasohol or

using ethanol or methanol) can attract

moisture which leads to separation and

formation of acids duringstorage. Acidc 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 untilfuel

lines and carburetor are empty. Use fresh fuel

next season. See Storage Instructionsfor

additional information. Never use engine or

carburetor cleaner products in fuel tank or

permanent damage may occur.

ACAUTION: Fill to bottom of gas tank

MOWINGTIPS

• Under certain conditione, such as very tall

grass, it may be necassary to raise the

height of cut to reduce pushing effort and to

keep from ovedoading the engine and

leaving dumps 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 previouslycut

path and mow slowly.

•For better grass begging and most cutting

conditions,the engine speed should be set

in the fast position.

•Pores in cloth grass catchers can become

filledwith dirt and dust with use and

catchers will collectless grass. To prevent

this, regularly hose catcher offwith 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 MOWINGTIPS

IMPORTANT: For best perfom'Bnce, keep

mower housing free of buiR-upgrass and

trash. Clean UNDERSIDE OF MOWER

HOUSING after each use. See "Cleaning"in

MAINTENANCE section of this manual.

• The special mulching blade will recurthe

grass clippings many times and reduce

them in size so that as they fall onto the

lawn they w'_ldisperse into the grass and

not be noticed. Also, the mulched grass will

biedegrade quicldyto provide nutrientsfor

the lawn. Always mulch with your highest

engine (blade) speed as this will provide

the best recurringaction of the blades.

•Avo'KIcutting 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

oft only the top one-third of the grass

blades. If the lawn is overgrown itwill 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 mu_ing, reduce your width of cut,

mow slowly and raise the rear of the lawn

mower one wheel adjuster setting higher

than the front.

* Cedain typas of grass and grass conddJons

may require that an area be mulched a

Second time to completely hkle the

clippings.When doing a second cut, mow

across or paqoondicular to the firstcut path.

•Change your cuttingpattem from week to

week. Mow north to south one week thon

change to east to weet the next week. This

wiUhelp prevent rnatting and graining of

the lawn.

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. "13ghtenoil plug

IMPORTANT: Never tamper with the engine

gevemor, 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 runningtoo fast or too slow,

take your lawn mower to an authorized

service center for repair end adjustment.

Immediately prepare your lawn mower for

storage at the end of the season or if the unit

will notbe used for 30 days or more.

LAWNMOWER

When lawn mower is to be stored for aperiod

of _rne, clean itthoroughly, remove all dirt,

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

•Clean entire lawn mower (See "CLEAN-

ING" in the Maintenance section of this

manual).

*Lubricate as shown in the MsintenarK;e

section of this rnanual.

•Be sure that all nuts, bolts,ecrews, and pins

are securely fastened. Inspect moving

_damage, breakage and wear.

if necassery.

•Touch up all rusted or chipped I.:__.'.'nt

surfaces; sand lightly before pemting.

entire handle assembly forward and

allow it to rest on mower.

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.

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

ispark 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.

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.
