and the U_S_Consumer Product Safety Commission. The blade turns when the engine is running.

BLADE CONTROL HANDLE--must be held down to

the handle to start and run the engine. Release to

stop the engine.

STARTER ROPE--used for starting the engine

PRIMER...-pumps additional fuel from the carburetor

to the cylinder for use when starting a cold engine.

ENGINE SPEED CONTROL LEVER--permits selec-

tion of fast or slow engine speed.

DRIVE CLUTCH CONTROL--must be held against

the handle to engage the wheel drive. Release the

drive clutch control to stop the wheels from driving.

SHIFT LEVER--is used to select one of five operat-

ing speeds for the mower.

OPERATMON

BEFORE USING YOUR LAWN MOWER, AGAIN REFER TO THE "SAFETY RULES" AS SHOWN ON PAGE 2

OF THIS MANUAL° ALWAYS BE CAREFUL

The operation of any lawn mower can result in foreign objects being thrown into the

eyes, which can result in severe eye damage Always wear safety glasses or eye

shields before starting power tool operation or while performing any adjustments or

repairs. We recommend Wide Vision Safety Mask for over spectacles or standard

glasses available at Sears Retail or Catalog Stores..

HOWTO USEYOURMOWER

TO STOP ENGINE

Release blade control handle to stop engine.

Disconnect the spark plug wire and move it away from

the spark plug to prevent accidental starting while

equipment is unattended.

ENGINE SPEED CONTROL

The engine speed is controlled by a lever (red knob)

located on the left side of the engine_ The "HI" posi-

tion is for starting engine, normal cutting and best per-

formance The "LOW" position is for light cutting, trim-

ming and fuel economy

BLADE CONTROL HANDLE

Your mower has a control handle which requires the

operator to be behind the handle to start and run the

mower When the operator releases the control han-

dle, the engine will stop and an internal brake helps

the blade to stop quickly.

When the operator leaves the operating position to

change the cutting height, pick up sticks or other

objects in the way, the engine will stop automatically

when the control handle is released.

DRIVE CLUTCH CONTROL

To engage the wheel drive, hold the drive clutch con-

trol against the handle. Releasing the drive clutch

control stops the wheels from driving. Release the

drive clutch control to slow down when negotiating an

obstacle, making a turn or stopping

SHIFT LEVER

The five speed shift lever is located on the left side of

the mower, beside the engine. See figure 7. To select

the mower speed, depress the lever, move to desired

position and release the lever. Position 1 is the slow-

est speed; position 5 is the fastest

eTo change cutting height, move adjuster levers

toward wheel& See figure 7. Move wheels up or

down to suit your requirements Be sure all four

levers are in the same setting

eAdjust cutting height to suit your requirements..

Refer to the "Mulching or Mowing Tips" on page 9.

(The height adjusters may seem hard to move when

new. They will operate easier after some use )

OIL

A 20 ounce bottle of SAE 30 oil is included with your

new lawn mower_

Only use high quality detergent oil rated with API ser-

vice classification SG. Select the oil's viscosity grade

according to your expected operating temperature_

WARNING: TO AVOID PERSONAL

INJURY, DO NOT MOVE THE SHIFT

LEVER WHEN THE ENGINE IS RUNNING. 5W30 m SAE 30

ADJUST CUTTING HEIGHT

Each wheel has an adjuster lever to set the cutting

height on your mower. They should always be set to the

same position.

eRaise wheels for low cut and lower wheels for high

cut

NOTE: Although multi-viscosity oil (5W30, 10W30,

etc,) improve starting in cold weather, these multi-vis -

cosity oils will result in increased oil consumption

when used above 32°E Check your oil level more fre-

quently to avoid possible engine damage from run-

ning low on oil.

OPERATION

e Place unit so engine is in a level position

e Remove oil fill cap and dipstick assembly Pour oil

slowly until oil level is to the FULL mark on dipstick

Crankcase capacity is approximately 1-1/4 pints

(20 ounces). DO NOT OVERFILL

NOTE: Crankcase oil should be changed after first

two (2) hours of operation and every twenty-five (25)

hours thereafter. Refer to ENGINE LUBRICATION

section.

eReplace oil fill cap and dipstick Tighten cap securely.

GAS

e Fill gas tank with about one (1) quart of clean,

fresh, lead-free grade automotive gasoline_ Low-

lead or regular gasoline is an acceptable substitute.

DO NOT use Ethyl or high octane gasoline Be cer-

tain container is clean and free from rust or foreign

particles Never use gasoline that may be stale

from long periods of storage in the container_

WARNING: EXPERIENCE INDICATES THAT ALCO-

HOL BLENDED FUELS (CALLED GASOHOL OR

USING ETHANOL OR METHANOL) 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 FOR

30 DAYS OR LONGER° USE FRESH FUEL NEXT

SEASON. SEE "STORAGE" SECTION FOR ADDI-

TIONAL INFORMATION.

NEVER USE ENGINE OR CARBURETOR CLEAN-

ER PRODUCTS IN THE FUEL TANK OR PERMA-

NENT DAMAGE MAY OCCUR.

FIGURE 10.

MULCHINGORMOWINGTiPS

eFor best results in normal and heavy mowing,

always run engine in "HI" speed position. "LOW"

speed is only for light cutting, trimming and fuel

economy.

@The grass condition at the time of mewing deter-

mines the proper mower cutting height setting for

best lawn appearance. For a healthy lawn, always

cut one-third or less of the total length of the grass

at any one cutting.

0Under 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

eFor extremely heavy cutting, use a slow ground

speed, and reduce the width of cut.

eUnder heavy conditions cross cut for additional

mulching of surface debris.

ENGINE OIL RECOMMENDATIONS

A 20 ounce bottle of SAE 30 oil is included with your

new lawn mower

Only use high quality detergent oil rated with API ser-

vice classification SG. Select the oil's viscosity grade

according to your expected operating temperature.

Colder -,_ 32°F _=- Warmer

5W30 [] SAE 30

NOTE: Although multi-viscosity oil (5E30, 10W30,

etc.) improves starting in cold weather, these multi-

viscosity oils will result in increased oil consumption

when used above 32 ° F_ Check your oil level more

frequently to avoid possible engine damage from run-

ning low on oil

WHEELS

DO NOT oil or grease the wheel bearings_ Viscous

lubricants will attract dust and dirt that will shorten the

life of the self-lubricating wheel bearings. If you feel

the wheels must be lubricated, use only a dry, silicone

type lubricant sparingly_

WHEEL ADJUSTERS

For easy operation, lubricate the wheel adjusters at

least once a season with light oil.

BRAKE SPRING BRACKET

Spray a light oil lubricant on the brake spring bracket,

located on the right rear corner of the engine, at least

once a season.

TRANSMISSION

The transmission is pre-lubricated and sealed at the

factory. It does not require checking. If disassembled

for any reason, fill with 2 ounces of Alvania grease,

part number 737-0168.

e Use a block of wood between blade and mower

deck to prevent blade from turning when bolt is

removed. Protect your hands with gloves and/or

wrap blade with heavy cloth

Remove blade bolt by turning counterclockwise

Use a 9/16" box or open-end wrench

TO REPLACE BLADE (See Figure 11):

ePut blade adapter on engine crankshaft

eFit blade in adapter. Be sure trailing edge of blade

is up towards engine.

eAssemble bolts, washers, and nuts in the exact

order of removal.

QUse block of wood to hold blade and tighten bolt

clockwise. The recommended torque for the center

is 450-600 in. Ibs. The recommended torque for the

blade adapter bolts is 200-350 in. IbsTorque

wrenches are available at most Sears stores and

through the catalog.

IMPORTANT: THE BOLT USED TO SECURE THE

BLADE TO ENGINE IS SPECIALLY HEAT-TREATED.

DO NOT SUBSTITUTE (SEE REPAIR PARTS).

CAUTION: A LOOSE BLADE CAN BE

DANGEROUS AND MAY MAKE THE

ENGINE HARD TO START,

Use only a Sears authorized replacement blade to get

the best cutting results.

•The blade can be sharpened with a file or on a

grinding wheel. Do not attempt to sharpen while on

the mower.

TO REMOVE BLADE (See Figure 11):

eTurn mower on its side. Make sure air filter and

carburetor are up.

eCare should be taken to keep the blade balanced.

An unbalanced blade will cause excessive vibration

when running and eventual damage to mower and

engine

CUSTOMER RESPONSIBILITIES

eTo 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, blade is not balanced. Sharpen

the heavy end until the blade is balanced.

@Clean the inside of the cover and the collar with a

clean cloth to remove any dirt accumulation.

®Insert new filter into cover_

®Put air filter cover and filter into collar aligning the

tab with the slot.

ePush in on cover and turn clockwise to tighten.

SPARK PLUG

Change your spark plug each year to make your

engine start easier and run better. Set spark plug gap

at 030 inch.

AIR FILTER

Your engine will not run properly and may be dam-

aged by using a dirty air filter..

Replace the air filter every year, more often if you mow

in very dusty, dirty conditions. Do not wash air filter.

TO CHANGE AIR FILTER (See Figure 12):

®Remove the air filter cover by turning counterclock-

wise to the stop and pull away from collar.

WARNING: DISCONNECT SPARK PLUG

WIRE FROM SPARK PLUG AND PLACE

WIRE WHERE IT CANNOT COME IN CON-

TACT WITH THE SPARK PLUG,

Turn mower on its side with carburetor and air filter

up.

Clean the underside of your mower after each use

by scraping to remove build-up of grass clippings,

leaves, dirt or other matter. If this debris is allowed

to accumulate, it will invite rust and corrosion, and

may prevent proper mulching

Clean your mower and engine often to keep build-

up of grass or debris from accumulating around

engine. A clogged engine runs hotter and shortens

engine life.

NOTE: We DO NOT recommend using a garden hose

to clean mower unless the electrical system, muffler,

air filter and carburetor are covered to keep water out.

Water in engine can result in shortening engine life.

STORAGE

Your mower and engine should be prepared for off-

season storage as follows:

MOWER

e Clean underside of mower housing (See "CLEAN-

ING" in "Customer Responsibilities" section of

manual).

e Inspect and replace/sharpen blade, if required (See

"BLADE CARE" in "Customer Responsibilities"

section of manual).

e Lubricate as shown in "Customer Responsibilities"

section of manual.

HANDLE

•You can fold your mower's handle for storage as

shown in figure 14. Remove the starter rope from

the rope guide. Loosen the two hand knobs on the

sides of the handle, and let the upper handle fold

down to the rear Move the hairpin clips to the outer

hole in the weld pins on the handle mounting brack-

ets. Refer to figure 3 Spread the sides of the lower

handle, and push it forward and down.

IMPORTANT: WHEN FOLDING HANDLE FOR

STORAGE OR TRANSPORTATION, BE CAREFUL

NOT TO BEND OR KINK THE CABLES.

FIGURE 14.

eTo place the handle in the operating position, refer to

"Assembly" on page 5 of this manual.

To prevent engine damage if lawn mower is not used

for more than 30 days, proceed as follows.

IMPORTANT: IT IS IMPORTANT TO PREVENT

GUM DEPOSITS FROM FORMING IN ESSENTIAL

FUEL SYSTEM PARTS SUCH AS CARBURETOR,

FUEL FILTER, FUEL HOSE, OR TANK DURING

STORAGE ALSO, FUEL (CALLED GASOHOL OR

USING ETHANOL OR METHANOL) CAN ATTRACT

MOISTURE WHICH LEADS TO SEPARATION AND

FORMATION OF ACID DURING STORAGE. ACIDIC

GAS CAN DAMAGE THE FUEL SYSTEM OF AN

ENGINE WHILE IN STORAGE

NOTE: Fuel stabilizer is an acceptable alternative in

minimizing formation of fuel gum deposits during stor-

age. Add stabilizer to gasoline in fuel tank in fuel tank

or storage container. Always follow mix ratio found on

stabilizer container. Run engine at least 10 minutes

after adding stabilizer to allow stabilizer to reach the

carburetor. Do not drain gas tank and carburetor if

using stabilizer.

eDrain the fuel tank Start the engine, and let it run

until fuel lines and carburetor are empty

e When storing the mower at the end of the season,

change the engine oil. Drain the oil after the engine

has been operated and is still warm, and refill the

crankcase with fresh oil

e Lubricate the piston/cylinder area by first removing

the spark plug and squirting clean engine oil into

the spark plug hole. Then cover the spark plug hole

with a rag to absorb oil spray. Next, rotate the

engine by pulling the starter two or three times

Finally, reinstall spark plug and attach spark plug

wire.

OTHER

eDo not store gasoline from one season to another

eReplace your gasoline can if your can starts to rust.

Rust and/or dirt in your gasoline can cause prob-

lems..

eDo not store your mower under any plastic cover.

Plastic cannot breathe which allows condensation

to form and cause the metal components of your

mower to rust.

WARNING

Do not mow on inclines with a slope in excess of 15 degrees (a rise of approximately 2-1/2 feet every 10 feet). If

operating a walk-behind mower on such a slope, it is extremely difficult to maintain your footing and you could

slip, resulting in serious injury.

Operate WALK-BEHIND mowers across the face of slopes, never up and down slopes.
