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. _;i,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.

_i,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. _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, familiar

with the instructions, to operate 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 ab-

solutely necessary. Always look down and

behind before andwhile 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 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 / 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 glass-

es 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 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 mower.

• 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 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 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 spill-

age. 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.

AWARIIING: 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

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. Pur-

chase fuel in quantities that can be used

within 30 days to assure fuel freshness.

& 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.

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.

A CAUTION: DO NOT overfill engine with

oil, or it will smoke heavily from the muffler on startup.

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 turn

the start key.

IMPORTANT: Do not crank engine more

than five continous seconds between each time you try to start. Wait 5 to 10 seconds

between each attempt.

• To start engine using the rope starter,

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 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

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

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").

(_ 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. Ifyou feel they

must be lubricated, use only adry, powdered

graphite type lubricant sparingly.

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 rear drive wheels each time you

mow to be sure they move freely. The

wheels not turning freely means trash,

grass cuttings, etc., may be inside the

drive wheel and dust cover area and must

be cleaned out to free drive wheels.

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 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 and 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.

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 unbalanced 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.

RASSCATCHER

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.

EAR 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.

TEMPERATURE RANGE ANTICIPATED BEFORE NEXT OIL CHANGE

NOTE: Multi-viscosity oils (5W30, 10W30 etc.) improve starting in cold weather, and you should check your engine oil level fre-

quently to avoid possible engine damage from running low on oil.

Change the oil after every 25 hours of opera-

tion or at least once a year if the lawn 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.

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 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.

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 muf- fler on startup.

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 SPECIFIC-

ATIONS" 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.

,_CAUTION: 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 agarden 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 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. & 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.
