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 oilto 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 lineon the dipstick. Pour oil slowly.

Do not over fill.

NOTE: Allow oil to settle down intoengine

for accurate reading. To read proper level,

tightenengine oil cap, then remove itto

read the dipstick.

3, Reinstall engine oil cap and tighten.

• Check oil level before each use. Add

oil if needed. Fill to full line on dipstick.

• Change the oil after every 25 hours of

operationor each season. You may

need to change the oil more often

under dusty,dirty conditions.

ADD GASOLINE

• Fillfuel tank. Use fresh, clean, regular

unleaded gasoitne with a minimum of

87 octane. Do not mixoil with gasoline.

Purchase fuel in quantities that can be

used within 30 days to assure fuel

freshness.

AWARNING: Experience indicatesthat

alcohol blended fuels (called gasohol or

using ethanol or methanol) can attract

moisture which leads to separation and

formation of acids dudngstorage. Acidic

gas can damage the fuel system ofan

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 untilthe fuel lines

and carburetor areempty. Usefresh fuel

nextseason. See Storage Instructionsfor

additional information. Never use engine

or carburetor cleaner products in the fuel

tank or permanent damage may occur.

A CAUTION: Fillto bottom ofgas tank

filler neck. Do not overfill. Wipe off any

spilled oil or fuel. Do not store, spillor use

gasoline near an open flame.

Engine oil cap

TO START ENGINE

• NOTE: Due to protective coatings on the

engine, a small amount of smoke may be

present dudng the initial use of the

productand should be considered

normal.

1. To start a cold engine, push primer

three (3) times before trying to 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 weather it may be

necessary to repeat pdming steps. In

warmer weather over pdming may cause

flooding and engine will not start. Ifyou do

floodengine, wait a few minutes before

attempting to start and do not repeat

priming steps.

MOWINGTIPS

• 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 ovedoading 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 usa

and catchers willcollect 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.

TO SHARPEN BLADE

NOTE: We do not recommend sharpening

blade - but ifyou do, be sure the blade is

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 sharpened with a file

or on a gdndingwheel. 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, if should

remain in a horizontal potion. If either

end of the blade moves downward,

sharpen the heavy end until the blade is

balanced.

GRASS CATCHER

• The grosscatcher may be hosed with

water, but must be dry when used.

• Check your grass catcher often for

damage or deterioration. Through

normal use it willwear. If catcher needs

replacing, replace only with a manufac-

turer approved replacement catcher.

Give the lawn mower model number

when ordedng.

DRIVE WHEELS

Check rear drive wheels each time you

mow to be sure they move freely. The

wheels notturningfreely means trash,

grass cuttings, etc., may be inside the

drive wheel and dust cover area and must

be cleaned out to free drive wheels.

If necessary to clean the drive wheels,

check both rear wheels.

1. Remove hubcaps and Iocknots.

2. Remove wheels from wheel adjuster

axles.

3. Remove any trash or grass cuttings

from inside the dust cover, pinionand/

or drive wheel gear teeth.

4. If you remove the drive pinions, wipe

clean with dry cloth. Reassemble dry.

Do notlubricate. Do not use oil or

FUEL SYSTEM

IMPORTANT: It Isimportantto prevent

gum deposits from forming in essential

fuel system parts suchas carburetor, fuel

filter,fuel hose, or tank during storage.

Also, expedance indicates that alcohol

blended fuels (called gesohol or using

ethanol or methanol) can attract moisture

which leads to separation and formation

ofacids 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 let it run until the

fuel lines and carburetor are empty.

• Never usa engine or carburetor cleaner

products inthe fuel tank or permanent

damage may occur.

• Use fresh fuel next season.

NOTE: Fuel stabilizer isan acceptable

alternative in minimizing the 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 minutesafter 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

1. Remove spark plug.

2. Pour one ounce (29 ml) of oilthrough

spark plug hole into cylinder.

3. Pull starter handle slowly a few times

to distributeoil.

164. Replace with new spark plug.

• Cover your unitwith a suitable protec-

tive cover that does not retain moisture.

where fumes may reach an open flame or

spark.Allow the engine to cool before
