BEFORE STARTING ENGINE

ADD OIL

Your lawnmower is shipped without oil in

the engine. Engine holds 20 oz. of oil.

For type and grade of oil to use, see

=ENGINE" in Maintenance section of this

manual.

1. Be sure lawnmower is level and area

around oil fill is clean.

2. Remove engine oil cap and fill to the

full line on the dipstick. Pour oilslowly.

Do not over fill.

NOTE: Allow oil to settle down intoengine

for accurate reading.To read proper level,

tighten engine oil cap, then remove it to

read the dipstick.

3. Reinstall engine oil cap and tighten.

• Check oil level before each use. Add

oil if needed. Fillto full line on dipstick.

• 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

• Fill fuel tank. Use fresh, clean, regular

unleaded gasoline with a minimum of

87 octane. Do not mix oil with gasoline.

Purchase fuel in quantities that can be

used within 30 days to assure fuel

freshness.

AWARNING: Expedanca indicatesthat

alcohol blended fuels (called gasohol or

using ethanol or methanol) can attract

moisture which leads to separation and

formation of acids dudng 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. Drainthe gas tank, start the

engine and let it run untilthe fuel lines

and carburetor are empty. Use fresh fuel

next season. See Storage Instructionsfor

additional information. Never use engine

or carburetor cleaner products in the fuel

tank or permanent damage may occur.

A CAUTION: Fillto bottomof gas tank

filler neck. Do not overfill. Wipe off any

spilled oil or fuel. Do not store, spillor use

gasoline near an open flame.

tiller cap

Engine oilcap

TO START ENGINE

. NOTE: Due to protective coatings on the

engine, a small amount of smoke may be

present duringthe initialuse of the

product and should be considered

normal.

1. To start a cold engine, push primer

three (3) times before tryingto start.

Use a firm push. This step is not

usually necessary when starting an

engine which has already run for a few

minutes.

2. 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

• To stop engine, release operator

presence control bar.

NOTE: In cooler weether it may be

necessary to repeat priming steps. In

warmer 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 repeat

pdming steps.

MOWlNGTIPS

• Under certain conditions, such as very

tall grass, it may be necessary to raise

the height of cut to reduce pushing

effortand 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.

• Pores in cloth grass catchers can

become filled with dirt and dust with use

and catchers will collectless grass. To

prevent this, regularly hose catcher off

with water and let dry before using.

• Keep top ofengine around starter clear

and clean of grass clippings and chaff.

This will help engine air flow and

extend engine life.

TO SHARPEN BLADE

NOTE: We do notrecommend sharpening

blade - but if you do, be sure the blade is

balanced.

Care should be taken to keep the blade

balanced. An unbalanced blade will cause

eventual damage to lawn mower or

engine.

•, The blade can be shaqoeP.edwith a file

or on a gdnding wheel. Do not attempt

to sharpen while on the mower.

• To check blade balance, drive a nail

into a beam or wall. Leave about one

inchof the straight nail exposed. Place

center hole of blade over the head of

the nail If blade is balanced, it should

remain in a horizontal position. If either

end of the blade moves downward,

sharpen the heavy end untilthe blade is

balanced.

GRASS CATCHER

• The grass catcher may be hosed with

water, butmust be dry when used.

• Check yourgrass catcher often for

damage or deterioration. Through

normal use it will wear. Ifcatcher needs

replacing, replace only with a manufac-

tursr approved replacement catcher.

Give the lawn mower model number

when ordering.

DRIVE WHEELS

Check rear drive wheels each time you

mow to be sure they move freely. The

wheels not tuming freely means trash,

grass cuttings,etc., may be inside the

drive wheel and dust cover area and must

be cleaned out tofree drive wheels.

If necessary to clean the drive wheels,

check beth rear wheels.

1. Remove hubcaps and Iouknuts.

2. Remove wheels from wheel adjuster

axles.

3. Remove any _.rashor grass cuttings

from inside the dustcover, pinion and/

or drive wheel gear teeth.

4. if you remove the drive pinions, wipe

clean with dry cloth. Reassemble dry.

Do not lubricate. Do not use oil or

grease.

NOTE: The piniongears, on both sides of

the mower, are the same, howover,they

must be installed o0rrectly. If installed

incorrectly,the ddve system will not work.

5. There are arrows embossed on both

sides of the piniongear. With the

arrow at the top of the pinion, the

arrow must point towards the front of

the mower. Ifthe arrow points tothe

rear of the mower, tam the pinion

around, then assemble to mower.

6. Place wheels back on adjuster axles.

• 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

aioctdcal system, muffler, air filter and

carburetor are covered to keep water

out. Water in engine can resultin

shortened engine life.

FUELSYSTEM

IMPORTANT: Itis importantto prevent

gum deposits from forming in essential

fuel systemparts suchas carburetor,fuel

filler, fuel hose, or tank during storage.

Also, expedance indicates that alcohol

blended fuels (called gasohol or using

ethanol or methanol) can attract moisture

which leads to separation and formation

of acids dudng storage. Acidic gas can

damage the fuel system of an engine

while in storage.

1. Drain the fuel tank.

2. Start the engine and letit run untilthe

fuel linesand 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 isan acceptable

allamative in minimizingthe formation of

fuel gum deposits during storage. Add

stabilizerto gasoline in fuel tank or

storage container. Alwaysfollow 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 usingfuel stabilizer.

ENGINE OIL

Drain oil (with engine warm) and replace

with clean engine oil. (See "ENGINE" in

the Maintenance section of this manual).

CYLINDER

1. Remove spark plug.

2. Pour one ounce (29 ml) of oil through

spark plug hole into cylinder.

3, Pull starter handle slowly a few times

to distributeoil.

164. Replace with new spark plug.

OTHER

• Donotstoregasolinefromoneseason

toanother.

• Replace your gasoline can if your can

starts to rust. Rust and/or dirt in your

gasoline will cause problems.

• if possible, storeyour unit indoors and

cover itto give protection from dust and

dirt.

• Cover your unit with a suitable protec-

tive cover that does not retain moisture.

breathe, which allows condensation to

form and will cause your unitto rust.

IMPORTANT: Never cover mower while

engone and exhaust areas are still warm.

A 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
