SAFETY RULES
IMPORTANT: This cutting machine is capable of amputating hands and feet and throwing ob-
jects.Failure to observe the following safety instructions could result in serious injury or death.
Look for this symbol to point out im-
portant safety precautions. It means
CAUTION!!! BECOME ALERT!!!
YOUR SAFETY IS INVOLVED.
WARNING: In order to prevent accidental
starting when setting up, transporting, ad-
justing or making repairs, always disconnect
spark plug wire and place wire where it cannot
come in contact with plug.
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
operate 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.

3
• 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 operator.
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 oper-
ating mower.
II. SLOPE OPERATION
Slopes are a major factor related to slip &
fall accidents which can result in severe
injury. 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
footing 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 ma-
chine and the mowing activity.
Never as-
sume 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
machine.
• 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.

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 spill-
age.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.

HOW TO USE YOUR LAWN MOWER
ENGINE SPEED
Theenginespeed wasset at the factory forop-
timum performance.Speed is not adjustable.
ENGINE ZONE CONTROL
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 lever rearward to the handle.
The farther toward the handle the lever
is pulled, the faster the unit will travel.
• Forward motion will stop when either
the operator presence control bar or
drive control lever are released. To stop
forward motion without stopping engine,
release the drive control lever 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 mow-
er forward slightly to disengage drive wheels.
DRIVE CONTROL ADJUSTMENT
Over time, the drive control system may be-
come “loose”, resulting in decreased speed.
There is a turnbuckle on the underside of 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. Turn nut on underside of drive control
to increase drive speed.
3. Operate mower to test drive speed.

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 op-
eration or each season. You may need to
change the oil more often under dusty, dirty
conditions.See“TOCHANGEENGINEOIL”
in the Maintenance 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. Pur-
chase fuel in quantities that can be used
within 30 days to assure fuel freshness.
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 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 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.
2. Hold operator presence control bar down
to the handle and pull starter handle quick-
ly.Do not allow starter rope to snap back.
NOTE: In cooler weather it may be necessary
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 attempting 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 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.
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
mowyourlawn isthe early afternoon. At this
time the grass has dried, yet the newly cut
area will not be exposed to direct sunlight.

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 al-
ready run for a few minutes.

MAINTENANCE
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 will 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.
• 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 sec-
ond time to completely hide the clippings.
When doing a second 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.
• 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”).

11
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 rub-
ber.
• 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, locknuts & 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 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 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, hardened washer).
NOTE: Remove the blade adapter and
check the key inside hub of blade adapter.
The key must be in good condition to work
properly. Replace adapter if damaged.
TO REPLACE BLADE
1. Position the blade adapter on the en-
gine crankshaft. Be sure key in adapter
and crankshaft keyway are aligned.
2. Position blade on the blade adapter
aligning the two (2) holes in the blade
with the raised lugs on the adapter.
3. Be sure the trailing edge of blade (oppo-
site sharp edge) is up toward the engine.
4. Install the blade bolt with the lock
washer and hardened washer into
blade adapter and crankshaft.
5. Use block of wood between blade and
lawn mower housing and tighten the
blade bolt, turning clockwise.
• The recommended tightening torque is
35-40 ft. lbs. / 47-54 N-m.
IMPORTANT: Blade bolt is heat treated.

TO SHARPEN BLADE
NOTE: We do not recommend sharpening
blade - but if you do, be sure the blade is 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
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.
ENGINE
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.
Change the oil after every 25 hours of opera-
tion or at 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.

4. Wipe off any spilled oil from lawn
mower or side of engine.
5. Slowly pour oil down the oil fill spout,
stopping every few ounces to check
the oil level with the dipstick.
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, re-
checking 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 plug.
AIR FILTER
Your engine will not run properly and may
be damaged by using a dirty air filter. Re-
place the air filter every 100 hours of op-
eration or every season, whichever occurs
first. Service air cleaner more often under
dusty conditions. Do not wash air filter.
TO CHANGE AIR FILTER
1. Remove the air filter by turning clockwise
to the stop and pull away from collar.
2. Remove filter from inside of cover.
3. Clean the inside of the cover and the
collar to remove any dirt accumulation.
4. Insert new filter into cover.
5. Put air filter cover and filter into collar
aligning the tab with the slot.
6. Push in on cover and turn counter-
clockwise to tighten.
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.

SERVICE AND ADJUSTMENTS
WARNING: To avoid serious injury, before performing any service or 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.
2. Reinstall debris shield and blade.
3. Return mower to upright position.
4. Install new belt on gearcase pulley.
5. Reinstall belt keeper and drive cover.

the possibility that objects will be thrown out
of the rear of the mower into the operator
mowing position. If the deflector becomes
damaged, it should be replaced.

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-up grass and
trash. Clean the underside of your mower
after each use.
CAUTION: Disconnect spark plug wire
from spark plug and place wire where it
cannot come in contact with plug.
• Clean underside of 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.

ENGINE
ENGINE SPEED
Your engine speed has 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 lawn mower to a
Sears or other qualified service center for
repair and adjustment.
CARBURETOR
Your carburetor is not adjustable. If your
engine does not operate properly due to
suspected carburetor problems, take your
lawn mower to a Sears or other qualified
service center for repair or adjustment.
IMPORTANT: Never tamper with the
engine governor, which is factory set
for proper engine speed. Overspeeding
the engine above the factory high speed
setting can be dangerous. If you think
the engine-governed high speed needs
adjusting, contact a Sears or other
qualified service center, which has proper
equipment and experience to make any
necessary adjustments.
TO ADJUST HANDLE
The handle can be mounted in a high or
low position. The mounting holes in the
bottom of lower handle are off center for
raising or lowering the handle.
1. Remove upper handle and wire tie(s)
securing cable(s) to lower handle.
2. Remove hairpin cotters from lower
handle bracket mounting pin.
3. Squeeze lower handle in to remove it
from mounting pins.
4. Turn lower handle over to raise or
lower handle.
5. Squeezelowerhandleinandpositionholes

STORAGE
Immediately prepare your lawn mower for storage at the end of the season or if the unit
will not be used for 30 days or more.
HANDLE
You can fold your mower handle for storage.
1. Squeeze the bottom ends of the lower
handle toward each other until the
lower handle clears the handle bracket,
then move handle forward.
2. Loosen upper handle mounting bolts
enough to allow it to be folded back.
IMPORTANT: When folding the handle for
storage or transportation, be sure to fold
the handle as shown or you may damage
the control cables.
• When setting up your handle from the
storage position, the lower handle will au-
tomatically lock into the mowing position.
LAWN MOWER
When lawn mower is to be stored for a period
of time, clean it thoroughly, remove all dirt,
grease, leaves, etc. Store in a clean, dry area.
1. Clean entire lawn mower (See
“CLEANING” in the Maintenance sec-
tion of this manual).
2. Lubricate as shown in the Maintenance
section of this manual.
3. Be sure that all nuts, bolts, screws, and
pins are securely fastened. Inspect
moving parts for damage, breakage
and wear. Replace if necessary.
4. Touch up all rusted or chipped paint
surfaces; sand lightly before painting.

NOTE: Fuel stabilizer is an acceptable
alternative in minimizing the formation
of fuel gum deposits during storage.
Add stabilizer to gasoline in fuel tank or
storage container. Always follow the mix
ratio found on stabilizer container. Run
engine at least 10 minutes after adding
stabilizer to allow the stabilizer to reach
the carburetor. Do not empty the gas tank
and carburetor if using fuel stabilizer.
ENGINE OIL
Drain oil (with engine warm) and replace
with clean engine oil. (See “ENGINE” in
the Maintenance section of this manual).
CYLINDER
1. Remove spark plug.
2. Pour 29 ml of oil through spark plug
hole into cylinder.
3. Pull starter handle slowly a few times
to distribute oil.
4. Replace with new spark plug.
OTHER
• Do not store gasoline from one season
to another.
• Replace your gasoline can if your can
starts to rust. Rust and/or dirt in your
gasoline will cause problems.
• If possible, store your unit indoors and
cover it to protect it from dust and dirt.
• Cover your unit with a suitable protective
cover that does not retain moisture. Do
not use plastic. Plastic cannot breathe,
which allows condensation to form and
will cause your unit to rust.
IMPORTANT: Never cover mower while
engine and exhaust areas are still warm.
CAUTION: Never store the lawn mower
with gasoline in the tank inside a building
where fumes may reach an open flame
or spark. Allow the engine to cool before
storing in any enclosure.
ENGINE
FUEL SYSTEM
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.
Alcohol 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.
• Empty the fuel tank by starting the en-
gine and letting it run until the fuel lines
and carburetor are empty.
• Never use engine or carburetor cleaner
products in the fuel tank or permanent
damage may occur.
• Use fresh fuel next season.
