mMPORTANT: This cutting machine is capable of amputating hands and feet and throw- ing objects. Failure to observe the following safety instructions could result in serious injury or death.

&Look for this symbol to point out

important 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 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.

&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. _, 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.

LGENERAL OPERATmON

* 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.

HI. 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.

inV.SAFE HANDUNG 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.

Neverfillcontainersinsidea vehicle,on atruck ortrailerbedwith a plasticliner. Alwaysplacecontainerson the ground awayfromyourvehiclebeforefilling. Removegas-poweredequipmentfrom

HOW TO USE YOUR LAWN MOWER ENGmNE SPEED

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

adjustable.

ENGmNE ZONE CONTROL

,_II,CAUTmON: 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.

DRmVE 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.

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" forward,

the drive cable is too tight. Rotate thumb- screw clockwise to loosen drive cable.

BEFORE STARTmNG 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.

ATTACH FUEL CAP CARTRmDGE

Your mower is equipped 'with a special

FRESH START TMfuel cap and continuous

fuel preserver cartridge. See the infor-

mation and instructions packed with the FRESH STARTTMcartridge.

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.

_1_DANGER: Cartridge fluid is HARMFUL OR FATAL IF SWALLOWED. Avoid contact

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.

ADD GASOUNE * 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 CAUTmON: Wipe off any spilled oil or fuel. Do not store, spill or use gasoline

near an open flame.

CAUTmON: 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.

1. To start a cold engine, push primer three (3) times before trying to start. Use a firm push. This step is not usually necessary when starting an engine which has already run for a few

minutes.

2. Hold operator presence control bar down to the handle and turn the start

key.

mMPORTANT: 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,

follow the steps above. Exchange the use of the starter rope for start key. Pull starter handle quickly. Do not allow starter rope to snap back.

NOTE: In cooler weather it may be neces- sary to repeat priming steps. In warmer weather over priming may cause flooding

and engine will not start. If you do flood engine wait a few minutes before at- tempting to start and do not repeat priming

steps.

MULCHmNG MOWmNG TIPS mMPORTANT: 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.

MOWmNG TIPS

• 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.

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.

LAWN MOWER

Always observe safety rules when per- forming any maintenance.

TmRES

• 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.

DRmVE 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.

1. Remove hubcaps, Iocknuts 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. 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 and 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.

4. Use block of wood between blade and lawn mower housing and tighten the blade bolt, turning clockwise.

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 bal- anced.An unbalanced blade will cause even-

tual 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, 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 heaw 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

Multis EP00. Do not substitute.

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°R 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 opera-

tion orat 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.

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.
