_/,Look for this symbol to point out

important safety precautions. It means

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

A 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 con- tact with plug. _WARNING" Engine exhaust, some of its

constituents, and certain vehicle compo-

nents 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.

& 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 & fa!l 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).

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.

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.

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-

Bess.

• i, 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, move throttle control

lever to STOP position. Wait until blade and all moving parts have stopped and

turn fuel valve to OFF position if you do

not intend to restart the engine soon.

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.

1. Be sure fuel valve is in the ON position.

2. To start a cold engine, move handle mounted throttle/choke control lever to

CHOKE position.

3. Pul! starter handle quickly. Do not allow starter rope to snap back.

4. Slowly move throttle control lever to FAST position after engine starts.

• To start a warm engine, move throttle control lever to FAST position, then fol- low steps above.

NOTE: Allow a cold engine to warm up for

one minute before starting the blade. See "BLADE CONTROL" in this section of this

manual.

MOWING TIPS

_i, CAUTION: Do not use de-thatcher

blade attachments on your mower. Such attachments are hazardous, wil! 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

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 wil! 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 recur 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 wil! 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 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 bolts.

NOTE: Protect your hands with gloves

and/or wrap blade with heavy cloth.

4. Remove blade bolts by turning counter- clockwise.

TO REPLACE BLADE

1. Position the blade. Be sure trailing edge of blade (opposite sharp edge) is up toward the engine and install the blade bolts.

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

blade bolts, turning clockwise.

• The recommended tightening torque is 36-44 ft. Ibs.

IMPORTANT: Blade bolts are heat treat-

ed. If bolts need replacing, replace only with approved bolts 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. 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.
