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.

&WARNING: 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.

&WARNING: 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.

A 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.

• 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 accidental 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.

AWARNING: 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). If a spark arrester is used, it should be maintained in effective working order by the operator.

In the state of California the above is required by law (Section 4442 of the California Public Resources Code). Other states may have similar laws. Federal laws apply on federal lands. A spark arrester for the muffler is available through your nearest Sears Parts & Repair Center (See the REPAIR PARTS section of this manual).

HOW TO USE YOUR LAWN MOWER

ENGINESPEED

The engine speed was set at the factory for optimum performance. Speed is not

adjustable.

ENGINE ZONE CONTROL

_ih,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.

DRIVE DRIVE

CONTROL CONTROL

ENGAGED DISENGAGED

DRIVE CONTROL ADJUSTMENT

Over time, the drive control system may

become "loose", resulting in decreased

speed. There is a thumbscrew on the

underside of the drive control housing to increase tension on the drive cable. Pro-

ceed as follows:

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

2. Rotate thumbscrew counter-clockwise to tighten the drive cable.

3. Operate mower to test drive speed.

4. If condition fails to improve after the above steps (forward speed remains the same), your drive belt is worn and should be replaced.

NOTE: If mower begins to "creep" for-

ward, the drive cable is too tight. Rotate thumbscrew clockwise to loosen drive

cable.

DRIVE CONTROL

• Self-propelling is controlled by hold- ing the operator presence control bar down to the handle and pulling the drive control bar up to the handle. The closer to the handle the bar is pulled, the faster

the unit will travel.

• Forward motion will stop when either the operator presence control bar or

drive control bar are released. To stop forward motion without stopping engine, release the drive control bar only. Hold operator presence control bar down against handle to continue mowing without self-propelling.

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

drive wheels.

• 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.

TO ADJUST CUTTING HEIGHT

Raise wheels for low cut and lower wheels

for high cut, adjust cutting height to suit your requirements. Medium position is

best for most lawns.

• To change cutting height, squeeze ad- juster lever toward wheel. Move wheel

up or down to suit your requirements. Be

sure all wheels are in the same setting.

NOTE: Adjuster is properly positioned when plate tab inserts into hole in lever. Also, 9-position adjusters (if so equipped) allow lever to be positioned between the

plate tabs.

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.

_i, 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.

ATTACH FUEL CAP CARTRIDGE

Your mower is equipped with a special

FRESH START TM fuel cap and continuous

fuel preserver cartridge. See the infor-

mation and instructions packed with the

FRESH START TM cartridge.

1. Snap cartridge into bottom of fuel cap.

NOTE: Do not remove the silver foil seal on the side of cartridge that snaps into fuel cap.

2. Grasp the white peel tab and pull to

remove the entire seal.

3. Screw fuel cap onto fuel tank after fill-

ing tank with gasoline.

Replace cartridge when empty (about once a season). Check preserver level

visually. A DANGER: Cartridge fluid is HARMFUL

OR FATAL IF SWALLOWED. Avoid con- tact to eyes, skin, or clothing. Do not take

internally. Do not inhale fluid vapor. Keep out of reach of children. If swallowed, call

a physician immediately.

Engine

oil cap

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. A 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.

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 prod- uct 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 clip-

pings. It may also be necessary to re- duce 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 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 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

heaw grass, reduce your width of cut

by overlapping previously cut path and

mow slowly.

MAXI_

• 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 assure proper air-fuel mixture and help your engine run better and last longer.

• Follow the maintenance schedule in this manual.

BEFORE EACH USE

• Check engine oil level.

• Check for loose fasteners.

LUBRICATION Keep unit well lubricated

(See "LUBRICATION CHART").

LAWN MOWER

Always observe safety rules when per- forming any maintenance.

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 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.

BLADE CARE For best results, blade must be kept sharp.

Replace a bent or damaged blade.

ACAUTION: Use only a replacement blade

app roved by the manufactu rer of you r mower. Using a blade not approved by the manu-

facturer of your mower is hazardous, 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 & attaching hardware

(bolt, lock washer & hardened washer).

TO REPLACE BLADE

1. Position blade on the blade adapter

aligning the two (2) holes in the blade with the raised lugs on the adapter.

2. Be sure the trailing edge of blade (oppo- •

site sharp edge) is up toward the engine.

3. Install the blade bolt with the lock

washer and hardened washer into blade adapter and crankshaft. 13 •

4. Use block of wood between blade and lawn mower housing and tighten the

blade bolt, turning clockwise.

• The recommended tightening torque is

35-40 ft. Ibs.

IMPORTANT: Blade bolt is heat treated.

If bolt needs replacing, replace only with

approved bolt shown in the Repair Parts section of this manual.

TO SHARPEN BLADE

NOTE: We do not recommend sharpening

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

is balanced. Care should be taken to keep

the blade balanced. An un balanced blade will cause eventual damage to 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, drive a nail into

a beam or wall. Leave about one inch of

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 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. If lubricant is required, use only Elf Mul-

tis EP00. Do not substitute.

ENGINE

LUBRICATION

Use only high quality detergent oil rated with

API service classification SG-SL. Select the

oil's SAE viscosity grade according to your

expected operating temperature.

SAE VISCOSITY GRADES

-20 0 30 32 40 60 80 100

-30 -20 -10 0 10 20 30 40

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.

2. Remove engine oil cap; lay aside on a clean surface.

3. 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.

4. Wipe off any spilled oil from lawn mower or side of engine.

5. Slowly pour oil down the oil fill spout, stopping every few ounces to check the oil level with the dipstick.

6. Stop adding oil when you reach the FULL mark on the dipstick. Wait a

minute to allow oil to settle.

7. 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.

8. Always be sure to retighten oil dipstick before starting engine.

9. Reconnect spark plug wire to spark plug. AIR FILTER

Your engine will not run properly and

may be damaged by using a dirty air

filter. Replace the air filter cartridge every

100 hours of operation or every season,

whichever occurs first. Service air cleaner

more often under dusty conditions.

TO CLEAN AIR FILTER

1. Loosen screw and tilt cover to remove.

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 making sure the tabs are aligned with

the slots in the back plate. Fasten

screw securely.
