,& WARNING" In order to prevent acci-

dental starting when setting up, transport- ing, adjusting or making repairs, always

disconnect spark plug wire and place wire

where it cannot come in contact with plug.

_i, CAUTION: Muffler and other engine

parts become extremely ,4Fk,,-, hot during operation and

remain hot after engine has stopped. To avoid

severe burns on contact, stay away from these areas.

AWARNING: Engine exhaust, some of its constituents, and certain vehicle compo-

nents contain or emit chemicals known to

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 richo-

chet back toward the operator. Stop 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 prop-

er operation and installation of accesso-

ries. Only use accessories approved 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. 3

• Disengage the self-propelled mecha- nism 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

injury. 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 footing could cause slipping.

III. CHILDREN

Tragic accidents can occur if the opera- tor 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 machine.

• Use extra care when approaching blind corners, shrubs, trees, or other objects

that may obscure vision.

AWARNING: CHILDREN CAN BE

INJURED BY THIS EQUIPMENT. The

American Academy of Pediatrics recom-

mends that children be a minimum of 12

year of age before operating a pedestrian controlled lawn mower and a minimum of

16 years of age before operating a riding lawn mower.

• When loadingor unloadingthis ma- chine,do notexceedthe maximum

recommendedoperationangle of 15°.

• Wear proper PersonalProtectiveEquip-

ment(PPE)while operatingthis ma-

chine, including(at a minimum)sturdy footwear,eye protection, andhearing

protection. Donot mow in shortsor

opentoed footwear.

Alwayslet someoneknowyou are outside mowing.

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.

• 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.

• 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.

• 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.

• If fuel is spilled on clothing, change clothing immediately.

• Never overfill fuel tank. Replace gas cap and tighten securely.

V. GENERAL SERVICE

• 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 acciden- tal starting.

• Keep nuts and bolts, especially blade attachment bolts, tight and keep equip- ment in good condition.

• Never tamper with safety devices. Check their proper operation regularly.

• Keep machine free of grass, leaves, or other debris build-up. Clean oil or fuel

spillage. Allow machine to cool before storing.

• Stop and inspect the equipment if you strike an object. Repair, if necessary,

before restarting.

• Never attempt to make wheel height adjustments while the engine is running.

• 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.

• Mower blades are sharp and can cut. Wrap the blade(s) or wear gloves, and use extra caution when servicing them.

• Do not change the engine governor set- ting or overspeed the engine.

• Maintain or replace safety and instruc- tion labels, as necessary.

HOW TO USE YOUR MOWER

ENGINE SPEED

Engine speed was set at the factory for optimum performance. It is not adjustable.

ENGINE ZONE CONTROL

_k.CAUTION: Federal regulations require

an engine control to be installed on this lawn mower in order to minimize the risk

of blade contact injury. Do not under any circumstances attempt to defeat the

function of the operator control. The blade turns when the engine is running.

• Your lawn mower is equipped with an operator presence control bar which

requires the operator to be positioned behind the lawn mower handle to start

and operate the lawn mower.

To keep drive control engaged when turning corners, push down on the

handle to lift the front wheels off the ground while turning lawn mower.

DRIVE CONTROL ADJUSTMENT

Over time, the drive control system may

become "loose", resulting in decreased

speed. There is a turnbuckle on the drive control housing to increase tension on the

drive cable. Proceed as follows:

1. Turn unit off and disconnect spark plug wire from spark plug.

2. Rotate turnbuckle on drive control to increase drive speed.

3. Operate mower to test drive speed.

Readjust as required.

4. If condition fails to improve after the above steps (forward speed remains

the same), your drive belt is worn and should be replaced.

Adjustment turnbuckle

DRIVE CONTROL

• Self-propelling is controlled by hold- ing the operator presence control bar

down to the handle and pulling the drive control lever rearward to the handle.

The further toward the handle the lever

is pulled, the faster the unit will travel.

• Forward motion will stop when either

the operator presence control bar or drive control lever are released. To stop forward motion without stopping engine,

release the drive control lever only. Hold

operator presence control bar down against handle to continue mowing with-

out self-propelling.

NOTE: If after releasing the drive control the mower will not roll backwards, push the mower forward slightly to disengage

drive wheels.

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.

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.

Engine oil cap

filler cap

TO STOP ENGINE

• To stop engine, release operator pres-

ence control bar.

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

_, 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 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 cut- ting 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 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 is wet. 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.

• 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

TIRES

* Keep tires free of gasoline, oil, or insect

control chemicals which can harm rubber.

* 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 inthe 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 (if equipped), lock-

nuts and 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.

BLADE CARE For best results, mower blade must be kept

sharp. Replace a bent or damaged blade.

_I, 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.

TO SHARPEN BLADE

NOTE: We do not recommend sharp- ening blade - but if you do, be sure the

blade is balanced. An unbalanced blade will cause eventual damage to lawn

mower or engine. * The blade can be sharpened with a file

or on a grinding wheel. Do not attempt to sharpen while on the mower.

* To check blade balance, you will need

a 5/8" diameter steel bolt, pin, or a cone balancer. (When using a cone balancer, follow the instructions supplied with it.)

NOTE: Do not use a nail for balancing

blade. The lobes of the center hole may appear to be centered, but are not. * Slide blade on to an unthreaded portion

of the steel bolt or pin and hold the bolt or pin parallel with the ground. If

blade is balanced, it should remain in a horizontal position. If either end of the blade moves downward, sharpen the

heavy end until the blade is balanced.

GRASS CATCHER

The grass catcher may be hosed with water, but must be dry when used. Check your grass catcher often for dam-

age or deterioration. Through normal

use it will wear. If catcher needs replac- ing, replace only with approved replace- ment catcher shown in the Repair Parts

section of this manual. Give the lawn

mower model number when ordering.

GEAR CASE

• 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.

• 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.

ENGINE LUBRICATION

Use only high quality detergent oil rated

with API service classification SG-SL. Se-

lect the oil's SAE viscosity grade according

to your expected operating temperature.

TEMPERATURE RANGE ANTICIPATED BEFORE NEXT OIL CHANGE

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 every 25 hours of op- eration orat least once a year if the 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, empty fuel tank by running engine until

fuel tank is empty.

1. Disconnect spark plug wire from spark

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

Remove engine oil cap; lay aside on a

clean surface.

Tip lawn mower on its side as shown and drain oil into a suitable container.

Rock lawn mower back and forth to re- move any oil trapped inside of engine.

/ /

Container

Wipe off any spilled oil from lawn

mower or side of engine.

Slowly pour oil down the oil fill spout, stopping every few ounces to check

the oil level with the dipstick.

Stop adding oil when you reach the

FULL mark on the dipstick. Wait a minute to allow oil to settle.

Continue adding small amounts of oil,

rechecking the dipstick until oil level

settles at FULL. DO NOT overfill, or engine will smoke heavily from the

muffler on startup.

Always be sure to retighten oil dipstick

before starting engine.

Reconnect spark plug wire to spark plug.

AIR FILTER Your engine will not run properly using

a dirty air filter. Replace paper cartridge every 100 hours of operation or every season, whichever occurs first. Service

air cleaner more often under dusty condi- tions.

1. Loosen screws and remove cover.

2. Carefully remove cartridge.

3. Clean by gently tapping on a flat sur- face. If very dirty, replace cartridge.

&CAUTION: Petroleum solvents, such

as kerosene, are not to be used to clean cartridge. They may cause deterioration

of the cartridge. Do not oil cartridge. Do not use pressurized air to clean or dry

cartridge.

4. Install cartridge, then replace cover.

MUFFLER

Inspect and replace corroded muffler as it could create a fire hazard and/or damage.

SPARK PLUG Replace spark plug at the beginning of

each mowing season or after every 100 hours of operation, whichever occurs

first. Spark plug type and gap setting are

shown in the "PRODUCT SPECIFICA-

TIONS" section of this manual.

CLEANING

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

mower after each use.

ACAUTION: Disconnect spark plug wire from spark plug and place wire where it

cannot come in contact with plug.

• 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 the outside of your lawn mower unless the electrical system, muffler, air filter and carburetor are cov-

ered to keep water out. Water in engine can result in shortened engine life.

WATER WASHOUT FEATURE Your lawn mower is equipped with a fitting

that allows quick and easy cleaning of the underside of the housing. To use this

feature, proceed as follows:

1. Move lawn mower to an area of cut grass or another hard surface.

NOTE: Water, grass and other debris will

drain from beneath the mower housing during the washout process.

2. Remove grass catcher and discharge chute assembly from lawn mower.

3. Close mulcher door (if equipped).

4. Connect a garden hose to the fitting

where shown.

IMPORTANT: Be sure the garden hose is not routed under the lawn mower housing

or entangled in the wheels.

5. Turn on water supply and check for leaks at the fitting.

If no leaks are present, start engine (as

described in the Operation section of this

manual) and let engine run until the under-

side of the lawn mower is clean. A WARNING: Do not engage the drive system during the washout process.

6. Shut off the engine.

7. Shut off water supply and remove hose from fitting.

CAUTION: Do not remove hose from fitting while engine is running. Water in

engine can result in shortened engine life.

8. Start engine (as described in the Op- eration section of this manual) and let

engine run for a full minute to remove excess water from mower.
