OIL (See Fig. 11)

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 w/dipstick and fill to the full line

on the dipstick,.

•Use 20 ozs.. of oil. Fortype and grade of oil to use, see

"ENGINE" in Customer Responsibilities section of this

manual.

o After the first two (2) hours of mowing, change the oil,

and every 25 hours thereafter. You may need to

change the oil more often under dusty, dirty conditions.

GAS (See Fig. 11)

oFill gasoline tank with fresh, clean, unleaded gasoline.

DO NOT USE PREMIUM GASOLINE. BE CAREFUL

NOT TO OVER FILL TANK.

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 stor*

age 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 Instruc-

tions for additional information. Never use engine or

carburetor cleaner products in fuel tank or permanent

damage may occur,.

MOWING TUPS

,Under certain conditions, such as very tall grass, itmay

be necessary to raise the height of cut to reduce

pushing effortand to keep from overloading the engine

and leaving clumps of grass clippings,

o For extremely heavy cutting, reduce tile width of cutby

overlapping previously cut path and mow slowly°

o For better grass bagging and most cutting conditions,

the engine speed should be set in the fast (,=_) posi-

tion.

o When using a rear discharge lawn mower in moist,

heavy grass, clumps of cut grass may not enter the

grass catcher. Reducegroundspeed (pushing speed)

anct/or run the lawn mower over the area a second time,.

°If a trail of clippings is left on the right side of arear

discharge mower', mow in a clockwise direction with a

small overlap to collect the clippings on the next pass.

° Pores in cloth grass catchers carl 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 chaffl_ This will help engine air' flow

and extend engine life.

MULCHSNG MOWING TIPS

IMPORTANT: FOR BEST PERFORMANCE, KEEP

MOWER HOUSING FREE OF BUILT-UP GRASS AND

TRASH. SEE "CLEANING" IN CUSTOMER

RESPONSIBILITIES SECTION OF THIS MANUAL,

o The special mulching blade will recut the grass clip-

pings 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 weL 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 (See Fig° 12). If the lawn is

overgrown it witl 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 by

overlapping previously cut path and mow slowly.

o Certain types of grass and grass conditions may re-

quire that an area be mulched a second time to com-

pletely hide the clippings. When doing a second cut,

mow across or perpendicular to the first cut path,.

° Change your cutting pattern from week to week, Mow

north to south one weekthen changeto east to west the

next week. This will help prevent matting and graining

of the lawn.

horizontal position, If either end of the blade moves

downward, sharpen the heavy end until the blade is

balanced,

according to your expected operating temperature°

8A_ V{SCOS[TY GRA[3E8

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°F. Check your engine oil level more frequently to avoid

possible engine damage from running low on oil.

Change the oil after the first two hours of operation and

every 25 hours thereafter or at least once a year if the lawn

mower is not used for 25 hours in one year.r

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°

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°

o Never use engine or'carburetor cleaner products inthe

fuel tank or' permanent damage may occur°

o Use fresh fuel next season.

NOTE: Fuel stabilizer is an acceptable alternative in

minimizing the formation of fuel gum deposits during stor-

age_ 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 t he 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 Customer Responsibilities

section of this manual),.

CYLINDER

= Remove spark plug.

= Pour one ounce (29 ml) of oil through spark plug hole

into cylinder_

= Pul! starter' handle slowly a few times to distribute oil

° Replace with new spark plug

OTHER

o 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 frorn 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 fom_ 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 thetank inside a build-

ing where fumes may reach an open

flameor spark. Allowthe enginetocool

before storing in any enclosure.
