SAFE OPERATION PRACTICES
A
DANGER: with any type of power equipment, carelessness or error on the part of the operator can result in serious
Your lawn mower was built to be operated according to the rules for safe operation in this manual. As
A
GENERAL OPERATION
Read this owner’s guide carefully In its entirety before attempting
to assemble this machine. Read, understand, and follow all
instructions on the machine and in the manual(s) before opera
tion. Be completely familiar with the controls and the proper use
of this machine before operating it. Keep this manual in a safe
place for future and regular reference and for ordering replace
ment parts.
Your rotary mower is a precision piece of power equipment, not a
plaything. Therefore, exercise extreme caution at all times. Your
unit has been designed to perform one job: to mow grass. Do not
use it for any other purpose.
Never allow children under 14 years old to operate a power
mower. Children 14 years old and over should only operate
mower under close parental supervision. Only responsible indi
viduals who are familiar with these rules of safe operation should
be allowed to use your mower.
Keep the area of operation clear of all persons, particularly small
children and pets. Stop engine when they are in the vicinity of
your mower to help prevent blade contact or thrown object
injury. Although the area of operation should be completely
cleared of foreign objects, an object may have been overlooked
and could be accidentally thrown by the mower in any direction
and cause serious personal injury to the operator or any others
allowed in the area.
Thoroughly inspect the area where the equipment is to be used.
Remove all stones, sticks, wire, bones, toys and other foreign
objects which could be picked up and thrown by the mower in
any direction and cause serious personal injury to the operator or
any others allowed in the area. Plan your mowing pattern to avoid
discharge of material toward roads, sidewalks, bystanders and
the like. To help avoid a thrown objects injury, keep children, ani
mals, bystanders and helpers at least 75 feet from the mower
while it is in operation.
Always wear safety glasses with side shields or safety goggles
during operation or while performing an adjustment or repair, to
protect eyes from foreign objects that may be thrown from the
machine in any direction.
Wear sturdy, rough-soled work shoes and close-fitting slacks and
shirts. Shirts and pants that cover the arms and legs and steel
toed shoes are recommended. Do not wear loose fitting clothes
or jewelry. They can be caught in moving parts. Never operate a
unit in bare feet, sandals, or sneakers.
Do not put hands or feet near or under rotating parts. Keep clear
of discharge opening at all times as the rotating blade can cause
injury.
Many injuries occur as a result of the mower being pulled over
the foot during a fall. Do not hang on to the mower if you are
falling; release the handle immediately.
Never pull the mower toward you while you are walking. If you
must back the mower away from a wall or obstruction first look
down and behind, and then follow these steps:
• Step back from the mower to fully extend your arms.
• Be sure you are well balanced with-sure footing.
• Pull the mower back slowly, no more than half way toward
you.
• Repeat these steps as needed.
' Do not operate the mower while under the influence of alcohol or
drugs.
' Disengage the self-propelled mechanism or drive clutch on units
so equipped before starting the engine.
injury. This lawn mower is capable of amputating hands and feet and throwing objects. Failure to observe
the following safety instructions could result in serious injury or death.
• The blade control handle is a safety device. Never attempt to
bypass its operation. Doing so makes the safety device inopera
tive and may result in personal injury through contact with the
rotating blade. The blade control handle must operate easily in
both directions and automatically return to the disengaged posi
tion when released.
• Never operate the mower in wet grass. Always be sure of your
footing. A slip and fall can cause serious personal injury. Keep a
firm hold on the handle and walk, never run. Mow only in daylight
or in good artificial light.
• Stop the blade when crossing gravel drives, walks or roads.
• If the equipment should start to vibrate abnormally, stop the
engine and check immediately for the cause. Vibration is general
ly a warning of trouble.
• Shut the engine off and wait until the blade comes to a complete
stop before removing the grass catcher or unclogging the chute.
The cutting blade continues to rotate for a few seconds after the
engine is shut off. Never place any part of the body in the blade
area until you are sure the blade has stopped rotating.
• Never operate mower without proper guards, grass catcher,
plates or other safety protective devices in place.
• Muffler and engine become hot and can cause a burn. Do not
touch.
• Only use accessories approved for this machine by the manufac
turer. Read, understand, and follow all instructions provided with
the approved accessory.
• If situations occur which are not covered in this manual, use care
and good judgment. Contact your dealer for assistance.
kll. SLOPE OPERATION
For your safety, use the slope gauge included as part of this manual
to measure slopes before operating this unit on a sloped or hilly
area. If the slope is greater than 15°, as shown on the slope gauge,
do not operate this unit on that area or serious injury could result.
DO:
• Mow across the face of slopes; never up and down. Exercise
extreme caution when changing direction on slopes.
• Watch for holes, ruts, hidden objects, or bumps. Tall grass can
hide obstacles.
• Always be sure of your footing. A slip and fall can cause serious
personal injury.
DO NOT:
• Do not mow near drop-offs, ditches or embankments. The opera
tor could loose footing or balance.
• Do not mow slopes greater than 15° as shown on the slope
gauge.
• Do not mow on wet grass. Reduced footing could cause slipping.
,111. CHILDREN
’Tragic accidents can occur if the operator is not alert to the
presence of children. Children are often attracted to the mower and
the mowing activity. Never assume that children will remain where
you last saw them.
• Keep children out of the mowing area and under the watchful
care of a responsible adult other than the operator.
• Be alert and turn mower off if a child enters the area.
• Before and while moving backwards, look behind and down for
small children.
• Never allow children under age 14 to operate the mower.
Page 3
Use extreme care when approaching blind corners, shrubs, trees,
or other objects that may obscure your vision of a child or
hazard.
IV. SERVICE
&
Use extreme care in handling gasoline and other fuels. They are
extremely flammable and the vapors are explosive.
• Use only an approved container.
• Never remove gas cap or add fuel while the engine is
running. Allow engine to cool at least two minutes before
refueling.
• Replace gasoline cap securely and wipe off any spilled gaso
line before starting the engine as it may cause a fire or
explosion.
• Extinguish all cigarettes, cigars, pipes and other sources of
ignition.
• Never refuel machine indoors because flammable vapors will
accumulate in the area.
» Never store the machine or fuel container inside where there
is an open flame or spark such as a gas water heater, space
heater, or furnace.
Never run an engine inside a closed area.
To reduce fire hazard, keep mower free of grass, leaves, or other
debris build-up. Clean up oil or fuel spillage. Allow mower to cool
at least 5 minutes before storing.
Before cleaning, repairing, or inspecting, make certain the blade
and all moving parts have stopped. Disconnect the spark plug
wire, and keep the wire away from the spark plug to prevent
accidental starting.
Check the blade and engine mounting bolts at frequent intervals
for proper tightness. Also, visually inspect blade for damage
(e.g., bent, cracked). Replace with blade which meets original
equipment specifications.
Keep all nuts, bolts, and screws tight to be sure the equipment is
in safe working condition.
Never tamper with safety devices. Check their proper operation
regularly.
After striking a foreign object, stop the engine, remove the wire
from the spark plug, and thoroughly inspect the mower for any
damage. Repair the damage before starting and operating the
mower.
Never attempt to make a wheel or cutting height adjustment while
the engine is running.
Grass catcher components are subject to wear, damage and dete
rioration, which could expose moving parts or allow objects to be
thrown. For safety protection, 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 setting or overspeed the
engine. Excessive engine speeds are dangerous.

MULCHING OR MOWING TIPS
• For 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 mowing 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.
• 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.
• For extremely heavy cutting, use a slow ground
speed, and reduce the width of cut.
• Under heavy conditions cross cut for additional
mulching of surface debris.

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
A
Use only a Sears authorized replacement blade to get
the best cutting results.
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-lubhcated and sealed at the
factory. It does not require checking. If disassembled
for any reason, fill with 2 ounces of Alvania grease,

CUSTOMER RESPONSIBILITIES
• 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, blade is not balanced. Sharpen
the heavy end until the blade Ls balanced.

tom holes In the handle over the weld pins in the
handle mounting bracket.
Reassemble the upper handle.
Place the hairpin clips in the Inner holes in the
weld pins and attach the starter rope as instructed
in the Assembly Section,
DRIVE CLUTCH ADJUSTIVIENT
The correct drive clutch adjustment varies with the
speed of the mower. The drive clutch adjustment may
be checked as follows. Without starting the engine,
engage the drive clutch control (squeeze control lever
against the handle) and pull the mower backward.
The wheels should lock. Then release the drive clutch
control and pull the mower backward, it should move
freely (or with only a small amount of resistance).
If the wheels lock up when pulled backward with the
drive clutch control released (engine off), or if mower
moves forward with the drive clutch control released
(engine running), turn the adjustment wheel, located
beneath the drive clutch control housing, toward the
operator to loosen the cable, See figure 12. Recheck
the adjustment as instructed above.
If the mower does not drive in low spaed, tighten the
cable by turning the adjustment wheel away from the
operator. Recheck the adjustment.
Periodic adjustment may also be necessary due to
normal stretch and wear on the belt. Adjustment may
be needed if the wheels seem to hesitate, but the
engine maintains the same speed. To tighten the
cable, move the adjustment wheel toward the right.
Always be certain to recheck the adjustment.
SIX SPEED SHIFT ADJUSTMENT
Periodic adjustment may be required due to normal
wear. Adjustment is needed if the shift lever cannot
be moved to all six positions.
• Loosen the nut which secures the adjustable cable
bracket, located on the left side of the engine. See
figure 13.
• Place the shift lever in high speed (6) position.
• Move the bracket to make certain it is loose. Then
slide It towards the rear of the unit as far as it will
go, so that the pulley halves (beneath the deck) are
against each other. Make certain the belt does not
interfere.
• Tighten the nut to secure the bracket in this
position.

SERVICE AND ADJUSTMENT
CARBURETOR
Your carburetor has a non-adjustable fixed main jet
for mixture control. It has been completely adjusted at
the factory. If your engine does not operate properly
due to suspected carburetor problems, take your
mower to an authorized Sears Service Center for
repair and adjustment.
ENGINE SPEED
Your engine slow and fast speeds have been factory
set. Do not attempt to increase engine speed or it
may result in personal injury. If you believe that the
engine is running too fast or too slow, take your
mower to an authorized Sears Service Center for
repair and adjustment.
REAR TRAIL SHIELD
The rear trail shield, attached between the rear
wheels of your mower, is provided to minimize the
possibility that objects will be thrown out the rear of
the mower toward the operator.
If the shield becomes damaged, it should be replaced.
BELT REMDVAL AND REPLACEMENT
• Place shift lever in third speed.
• Disconnect the spark plug wire and ground it
against the engine.

STORAGE
Your mower and engine should be prepared for off
season storage as follows:
MOWER
• Clean underside of mower housing (See “CLEAN
ING” in “Customer Responsibilities” section of
manual).
• Inspect and replace/sharpen blade, if required (See
“BLADE CARE” in “Customer Responsibilities”
section of manual).
• Lubricate as shown in “Customer Responsibilities”
section of manual.
HANDLE
• You can fold your mower’s handle for storage as
shown in figure 17. 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.
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.
• Drain the fuel tank. Start the engine, and let it run
until fuel lines and carburetor are empty.
• 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.
• 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
• Do not store gasoline from one season to another.
FIGURE 17.
• To place the handle in the operating position, refer to
“Assembly” on page 6 of this manual.
• Replace your gasoline can if your can starts to rust.
• Do not store your mower under any plastic cover.
