height of cut to reduce pushing effort and to trash. Clean UNDERSIDE OF MOWER

keap from overloading the engine and

leaving clumps of grass clipp_s. It may

aise be necessary to reduce ground speed

and/or run the lawn mower over the area a

second time.

• For extremely heavy cutting,reduce the

dth ofc=byov ng prev cut

• For better grass bagging and most cutting

conditions,the engine speed should be set

inthe fast pos'_don.

• Porea in cloth grass catchers can become

filledwith dirt and dustwith use and

catcherswill collect less grass. To prevent

this, regularlyhose catcher off with water

and let dry before using.

•Keep top of angine around starter clear

HOUSING after each use. See "Cleaning"in

MAINTENANCE section of this manual.

• The special mulching blade will recutthe

grass cl'_opingsmany times and reduce

them in size so that as they fail onto the

lawn they will dispeme 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 re_fting actien of the I_des.

•Avoid cuttingyour lawn when itis weL Wet

grass tends to form dumps and inte=feres

wi_ the mulchingac'don.The best time to

mow your lawn is the early afternoon.At

this time the grass has dried and the newiy

cut area will net be exposed to the direct

sun.

• For best results,adjust the lawn mower

cutling heightso that the lawn mower cuts

off only the top one-thirdof the grass

blades. If the lawn is overgrown it will be

necessary to raise the heightof cut to

reduce pushing effort and to keep from

overloading the engine and leaving

clumps of mulched gra,ss.For extremely

heavy mulching, reduce your width of cut,

mow slowiyand raisethe rear of the lawn

mower one wheal adjuster setting higher

than the front.

•Certain types of grass and grass comr_ions

may require that an area be mulched a

second lima to completely hide the

cr_pings. When doing a second cut, mow

acroseor peq_e_rK_jlar to the tirst cut path.

•Chenge your cutlJngpaftem from weak to

weak. Mow northto south one week then

change to east to west the next week. This

will help prevent matting and grairdngof

the lawn.

LUBRICATION

Use only high quality detergent oil rated

with API service classification SF, SH or

SG. Select the oil's SAE viscosity grade

according to your expected operating

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°R 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 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.

SPARK PLUG

Change your spark plug each year to

make your engine start easier and run

better. Set spark plug gap at .030 inch.

CLEANING

IMPORTANT: For best performance, keep

"mower housing free of built---up grass

and trash. Clean underside of mower

housing after each use.

CAUTION: spark plug wire

Disconnect

•Turn lawn mower on its side. Make sure

air filler 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 electdcal system, muffler, air

filter and carburetor are covered to

keep water out. Water in engine can

result in shortened engine life.

governor,which is factoryset 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, contactyour

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 and adjustment.

Immediately prepare your lawn mower for

storage atthe end of the season or if the unit

will not be used for 30 days or mere.

FUEL SYSTEM

IMPORTANT: It is important to prevent

_uUmdeposits 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.

iever 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 addin_l

stabilizer to allow the stabilizer to raacn

the carburetor. Do not drain the ._as tank

and carburetor if using fuel stabihzer.

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 9asoline 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.
