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 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.

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.

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.

IoGENERAL OPERATION

• Read, understand,andfollowall

instructionson the machineandinthe manual(s)beforestarting. Be thoroughly

familiarwith the controlsandthe proper

useof the machinebeforestarting.

• Do not put hands orfeet nearor under

rotatingparts. Keepclearof the dis-

chargeopeningatall times.

• Only allow responsibleindividuals,who

are familiarwith 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.

il, 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.

i11. 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.

HOW TO USE YOUR LAWN MOWER

ENGINE SPEED

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

ENGINE ZONE CONTROL _I, 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 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,

MOVE DOWN

TO NEXT HOLE

DRIVE CONTROL ADJUSTMENT

Over time, the drive control system may

become "loose", resulting in decreased

speed. There are holes in 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. Loosen nut, move drive control hous- ing down handle to the next hole and

retighten nut.

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.

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 set-

ting.

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. 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.

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.

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 product

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 usu- ally 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.

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, 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.

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.

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,

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.

CAUTION: Use only a replacement blade

approved bythe manufacturer of your 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).

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.

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 Texaco

Starplex Premium 1 Grease, Part No.

750369. Do not substitute.

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.

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.

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.

_I, 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.

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.

A:_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 a garden 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 short- ened engine life.

CLEAN UNDER DRIVE COVER Clean under drive cover at least twice a sea- son. Scrape underside of cover with putty

knife or similar tool to remove any build-up

of trash or grass on underside of drive cover.

_, WARNING: To avoid serious injury,

before performing any service and adjustments:

1. Release control bar and stop engine.

2. Make sure the blade and all moving parts have completely stopped.

3. Disconnect spark plug wire from spark plug and place wire where it cannot come in contact with plug.
