ing objects. Failure to observe the following safety instructions could result in serious injury or death.

_;_Look for this symbol to point out impor- tant safety precautions. It means

CAUTION!!! BECOME ALERT!!! YOUR SAFETY IS INVOLVED.

_, WARNING: In order to prevent ac- cidental starting when setting up, trans-

porting, adjusting or making repairs,

always disconnect spark plug wire and

place wire where it cannot come in contact with plug. _kWARNING" Engine exhaust, some of its

constituents, and certain vehicle components contain or emit chemicals known to the State

of California to cause cancer and birth defects or other reproductive harm.

AWARNING" Battery posts, terminals and

related accessories contain lead and lead compounds, chemicals known to the State

of California to cause cancer and birth defects or other reproductive harm. Wash

hands after handling.

_I, CAUTION" Muffler and other engine

parts become extremely hot during operation and remain hot after engine has stopped. To avoid severe burns on contact, stay away from these areas.

I. GENERAL OPERATION , Read, understand, and follow all

instructions on the machine and in the manual(s) before starting. Be thoroughly

familiar with the controls and the proper use of the machine before starting.

, Do not put hands or feet near or under

rotating parts. Keep clear of the dis- charge opening at all times.

, Only allow responsible individuals, who

are familiar with the instructions, to oper- ate the machine.

, Clear the area of objects such as rocks,

toys, wire, bones, sticks, etc., which could be picked up and thrown by blade.

, Be sure the area is clear of other people

before mowing. Stop machine if anyone enters the area.

, Do not operate the mower when bare-

foot or wearing open sandals. Always wear substantial foot wear.

, Do not pull mower backwards unless

absolutely necessary. Always look down and behind before and while moving

backwards.

, Never direct discharged material toward

anyone. Avoid discharging material against a wall or obstruction. Material

may richochet back toward the opera- tor. Stop the blade when crossing gravel

surfaces.

, Do not operate the mower without

proper guards, plates, grass catcher or other safety protective devices in place.

, See manufacturer's instructions for

proper operation and installation of accessories. Only use accessories ap- proved by the manufacturer.

, Stop the blade(s) when crossing gravel

drives, walks, or roads.

, Stop the engine (motor) whenever you

leave the equipment, before cleaning the mower or unclogging the chute.

, Shut the engine (motor) off and wait until

the blade comes to complete stop before removing grass catcher.

, Mow only in daylight or good artificial

light.

, Do not operate the machine while under

the influence of alcohol or drugs.

, Never operate machine in wet grass.

Always be sure of your footing: keep a firm hold on the handle; walk, never run.

, Disengage the self-propelled mech-

anism or drive clutch on mowers so equipped before starting the engine.

, If the equipment should start to vibrate

abnormally, stop the engine (motor) and check immediately for the cause. Vibra-

tion is generally a warning of trouble.

, Always wear safety goggles or safety

glasses with side shields when operating mower.

II. SLOPE OPERATION

Slopes are a major factor related to slip & fall accidents which can result in severe in-

jury. All slopes require extra caution. If you feel uneasy on a slope, do not mow it.

DO:

, Mow across the face of slopes: never

up and down. Exercise extreme caution when changing direction on slopes.

, Remove obstacles such as rocks, tree

limbs, etc.

, Watch for holes, ruts, or bumps. Tall

grass can hide obstacles.

DO NOT:

, Do not trim near drop-offs, ditches or

embankments. The operator could lose

footing or balance. , Do not trim excessively steep slopes. , Do not mow on wet grass. Reduced foot-

ing could cause slipping.

III. CHILDREN

Tragic accidents can occur if the operator

is not alert to the presence of children.

Children are often attracted to the machine and the mowing activity. Never assume

that children will remain where you last saw them.

, Keep children out of the trimming area

and under the watchful care of another

responsible adult. , Be alert and turn machine off if children

enter the area. , Before and while walking backwards,

look behind and down for small children. , Never allow children to operate the ma-

chine. , Use extra care when approaching blind

corners, shrubs, trees, or other objects

that may obscure vision.

IV. SAFE HANDLING OF GASOLINE

Use extreme care in handling gasoline. Gasoline is extremely flammable and the vapors are explosive.

, Extinguish all cigarettes, cigars, pipes

and other sources of ignition.

, Use only an approved container. , Never remove gas cap or add fuel with

the engine running. Allow engine to cool before refueling.

, Never refuel the machine indoors. , Never store the machine or fuel contain-

er where there is an open flame, spark or pilot light such as a water heater or on other appliances.

o Never fill containers inside a vehicle, on

a truck or trailer bed with a plastic liner. Always place containers on the ground

away from your vehicle before filling.

o Remove gas-powered equipment from

the truck or trailer and refuel it on the ground. If this is not possible, then

refuel such equipment with a portable container, rather than from a gasoline dispenser nozzle.

o Keep the nozzle in contact with the rim

of the fuel tank or container opening at all times until fueling is complete. Do not use a nozzle lock-open device.

o If fuel is spilled on clothing, change

clothing immediately.

o Never overfill fuel tank. Replace gas

cap and tighten securely.

V. GENERAL SERVICE

o Never run a machine inside a closed

area.

Never make adjustments or repairs with the engine (motor) running. Disconnect the spark plug wire, and keep the wire

away from the plug to prevent accidental starting.

o Keep nuts and bolts, especially blade

attachment bolts, tight and keep equip- ment in good condition.

o Never tamper with safety devices. Check

their proper operation regularly.

o Keep machine free of grass, leaves, or

other debris build-up. Clean oil or fuel spillage. Allow machine to cool before storing.

o Stop and inspect the equipment if you

strike an object. Repair, if necessary, before restarting.

o Never attempt to make wheel height

adjustments while the engine is running.

o Grass catcher components are subject

to wear, damage, and deterioration,

which could expose moving parts or

allow objects to be thrown. Frequently check components and replace with

manufacturer's recommended parts,

when necessary.

o Mower blades are sharp and can cut.

Wrap the blade(s) or wear gloves, and use extra caution when servicing them.

o Do not change the engine governor set-

ting or overspeed the engine.

o Maintain or replace safety and instruc-

tion labels, as necessary.

&WARNING: This lawn mower is equipped with an internal combustion engine and

should not be used on or near any unimproved forest-covered, brush-covered or grass-covered land unless the engine's exhaust system is equipped with a spark arrester meeting applicable local or state laws (if any).

BEFORE STARTING ENGINE

ADD OiL

Your lawnmower is shipped without oil in the engine. For type and grade of oil to

use, see "ENGINE" in the Maintenance

section of this manual. & CAUTION: DO NOT overfill engine with oil, or it will smoke heavily from the muffler

on startup.

1. Be sure lawnmower is level.

2. Remove oil dipstick from oil fill spout.

3. You receive a container of oil with the unit. Slowly pour the entire container

down the oil fill spout into the engine.

NOTE: Initial oil fill requires only 18 oz.

due to residual oil in engine from the

manufacturers 100% quality testing. When

changing oil you may need 20 oz.

4. Insert and tighten dipstick.

iMPORTANT:

, Check oil level before each use. Add oil

if needed. Fill to 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. See "TO CHANGE ENGINE OIL" in the Mainte-

nance section of this manual.

Gasoline

filler cap

ADD GASOLINE , Fill fuel tank to bottom of tank filler neck.

Do not overfill. 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 fresh-

ness.

,A CAUTION: Wipe off any spilled oil or fuel. Do not store, spill or use gasoline

near an open flame. & CAUTION: Alcohol blended fuels

(called gasohol or using ethanol or metha-

nol) 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 storage of 30

days or longer. Empty the gas tank, start the engine and let it run until the fuel lines and carburetor are empty. Use fresh fuel next season. See Storage Instructions for additional information. Never use engine

or carburetor cleaner products in the fuel tank or permanent damage may occur.

TO STOP ENGINE , To stop engine, release operator pres-

ence control bar.

Engine

oil cap

TO START ENGINE NOTE: Due to protective coatings on the

engine, a small amount of smoke may be present during the initial use of the product

and should be considered normal. NOTE: Your engine is equipped with an

automatic choke system. No priming or choking is required before starting. , To start engine, hold operator presence

control bar down to the handle and pull starter handle quickly. Do not allow starter rope to snap back.

MOWING TiPS

A CAUTION: Do not use de-thatcher

blade attachments on your mower. Such attachments are hazardous, will damage your mower and could void your warranty.

. Under certain conditions, such as very

tall grass, it may be necessary to raise the height of cut to reduce pushing effort and to keep from overloading 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 previously cut path and mow slowly.

. For better grass bagging and most cut-

ting conditions, the engine speed should be set in the FAST position.

. For side discharge lawn mowers, cutting

in a counter-clockwise direction, start- ing at the outside of the area to be cut, spreads grass clippings more evenly

and puts less load on the engine. To keep clippings off of walkways, flower beds, etc., make the first cuts in a clock-

wise direction.

. Pores in cloth grass catchers can be-

come 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 chaff. This will help engine air flow and extend

engine life.

MULCHING MOWING TiPS

IMPORTANT: For best performance, keep mower housing free of built-up

grass and trash. See "CLEANING" in the

Maintenance section of this manual.

, The special mulching blade will recut

the grass clippings 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 recut- ting action of the blades.

, Avoid cutting your lawn when it iswet.

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, yet the newly cut area will not be

exposed to direct sunlight.

, 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. If the lawn is overgrown it

will 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 grass, reduce your width of cut by overlapping previously cut path and mow slowly.

MAX 1/3

, Certain types of grass and grass

conditions may require that an area be mulched a second time to completely

hide the clippings. When doing a sec- ond cut, mow across (perpendicular) to the first cut path.

, Change your cutting pattern from week

to week. Mow north to south one week then change to east to west the next

week. This will help prevent matting and

graining of the lawn.

GENERAL RECOMMENDATIONS

The warranty on this lawn mower does not cover items that have been subjected to operator abuse or negligence. To receive

full value from the warranty, operator must

maintain unit as instructed in this manual.

Some adjustments will need to be made

periodically to properly maintain your unit.

At least once a season, check to see if you should make any of the adjustments

described in the Service and Adjustments section of this manual.

o At least once a year, replace the spark

plug, clean or replace air filter element and check blade for wear. A new spark

plug and clean/new air filter element assure proper air-fuel mixture and help your engine run better and last longer.

o Follow the maintenance schedule in this

manual.

BEFORE EACH USE

o Check engine oil level. o Check for loose fasteners.

LUBRICATION

Keep unit well lubricated (See "LUBRICATION CHART").

LUBRICATION CHART

guard hinge

(_ Handle bracket mounting pins

_ Spray lubricant

See "ENGINE" in Maintenance section.

IMPORTANT: Do not oil or grease plastic

wheel bearings. Viscous lubricants will attract dust and dirt that will shorten the life of

the self-lubricating bearings. If you feel they

must be lubricated, use only a dry, powdered

graphite type lubricant sparingly.

LAWN MOWER

Always observe safety rules when per- forming any maintenance.

TIRES o Keep tires free of gasoline, oil, or insect

control chemicals which can harm rub- ber.

o Avoid stumps, stones, deep ruts, sharp

objects and other hazards that may cause tire damage.

DRIVE WHEELS Check front drive wheels each time before you mow to be sure they move freely.

The wheels not turning freely means trash, grass cuttings, etc. are in the drive wheel

area and must be cleaned to free drive wheels.

If necessary to clean the drive wheels, be sure to clean both front wheels.

1. Remove hubcaps, Iocknuts & washers.

2. Remove wheels from wheel adjusters.

3. Remove any trash or grass cuttings

from inside the dust cover, pinion and/ or drive wheel gear teeth.

4. Put wheels back in place.

NOTE: If after cleaning, the drive wheels do not turn freely, contact a Sears or other

qualified service center.

GEAR CASE

o To keep your drive system working

properly, the gear case and area around the drive should be kept clean and free of trash build-up. Clean under the drive

cover twice a season.

o The gear case is filled with lubricant to

the proper level at the factory. The only time the lubricant needs attention is if

service has been performed on the gear case.

BLADE CARE

For best results, mower blade must be

kept sharp. Replace a bent or damaged

blade. A CAUTION" Use only a replacement

blade approved by the manufacturer of your mower. Using a blade not approved

by the manufacturer of your mower is haz- ardous, could damage your mower and void your warranty.

TO REMOVE BLADE

1. Disconnect spark plug wire from spark plug and place wire where it cannot come in contact with plug.

2. Turn lawn mower on its side. Make sure air filter and carburetor are up.

3. Use a wood block between blade and mower housing to prevent blade from

turning when removing blade bolt.

NOTE: Protect your hands with gloves

and/or wrap blade with heavy cloth.

4. Remove blade bolt by turning counter- clockwise.

5. Remove blade and attaching hardware (bolt, lock washer, hardened washer).

NOTE: Remove the blade adapter and check the key inside hub of blade adapter. The key must be in good condition to work

properly. Replace adapter if damaged.

CLEANING

IMPORTANT: For best performance, keep lawn mower housing free of built- grass and trash. Clean the underside of your lawn mower after each use.

ACAUTION" Disconnect spark plug wire

from spark plug and place wire where it cannot come in contact with plug.

o Clean the underside of your mower by

scraping to remove build-up of grass/ trash.

o Clean engine often to keep trash from

accumulating. A clogged engine runs

hotter and shortens engine life.

o Keep finished surfaces and wheels free

of all gasoline, oil, etc.

o We do not recommend using a garden

hose to clean lawn mower unless the

electrical system, muffler, air filter and carburetor are covered to keep water

out. Water in engine can result in short- ened engine life.

CLEAN UNDER DRIVE COVER Clean under drive cover at least twice a

season. Scrape underside of cover with putty knife or similar tool to remove any build-up of trash or grass on underside of

drive cover.

ENGINE

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 engine is running too fast or too slow, take your mower to a Sears or other qualified

service center for repair and adjustment. CARBURETOR

Your carburetor is not adjustable. If your engine does not operate properly due to sus-

pected carburetor problems, take your lawn mower to a Sears or other qualified service

center for repair and/or adjustment.

IMPORTANT: Never tamper with the engine governor, which is factory set for proper en- gine speed. Overspeeding the engine above

the factory high speed setting can be danger- ous. If you think the engine-governed high speed needs adjusting, contact a Sears or other qualified service center, which has

proper equipment and experience to make any necessary adjustments.
