• Do not pull mower backwards unless
absolutely necessary. Always look down
and behind before and while moving
backwards.
• 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 and walk; never
run.
• Disengage the self-propelled mech-
anism or drive clutch on mowers so
equipped before starting the engine
(motor).
• 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
and fall accidents which can result in
severe injury. All slopes require extra cau-
tion. 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 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 machine.
• Use extra care when approaching blind
corners, shrubs, trees, or other objects
that may obscure vision.
IV. SERVICE
• Use extra care in handling gasoline and
other fuels. They are flammable and
vapors are explosive.
- Use only an approved container.
- Never remove gas cap or add fuel with
the engine running. Allow engine to
cool before refueling. Do not smoke.
- Never refuel the machine indoors.
- Never store the machine or fuel
container inside where there is an
open flame, such as a water heater.
• Never run a machine inside a closed area.
• Never make adjustments or repairs with
the engine (motor) running.Disconnect the
spark plug wire, and keep the wire away
from the plug to prevent accidental starting.
• Keep nuts and bolts, especially blade
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 adjust-
ments while the engine (motor) 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.
• 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 set-
ting or overspeed the engine.

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 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 attempt-
ing to start and do not repeat priming
steps.
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.
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.
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.
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.

MOWING 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 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.
• For side discharge lawn mowers, cutting
in a counter-clockwise direction, start-
ing at the outside of the area to be cut,
spreads grass clippings more evenly
and puts less load on the engine. To
keep clippings off of walkways, flower
beds, etc., make the first cuts in a clock-
wise direction.
• 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 Mainte-
nance 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.
• 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 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.

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.
• 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”).
LUBRICATION CHART
➀Spray lubricant
➁See "ENGINE" in Maintenance section.
IMPORTANT: Do not oil or grease plastic
wheel bearings. Viscous lubricants will
attract dust and dirt that will shorten the life of
the self-lubricating bearings. If you feel they
must be lubricated, use only a dry, powdered
graphite type lubricant sparingly.

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.
BLADE CARE
For best results, blade must be kept sharp.
Replace bent or damaged blades.
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 hard-
ware (bolt, lock washer and 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 (op-
posite 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.
IMPORTANT: Blade bolt is heat treated.
If bolt needs replacing, replace only with
approved bolt shown in the Repair Parts
section of this manual.
TO SHARPEN BLADE
NOTE: We do not recommend sharpening
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 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
(If purchased as an accesssory)
• 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.

alternative in minimizing the formation of
fuel gum deposits during storage. Add
stabilizer to gasoline in fuel tank or stor-
age 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 carbu-
retor. Do not empty the gas tank and
carburetor if using fuel stabilizer.

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
operation 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.
Container
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,
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.
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, which ever occurs
first. Spark plug type and gap setting are
shown in the “PRODUCT SPECIFICA-
TIONS” 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 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.
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 coun-
terclockwise 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.

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.
LAWN MOWER
When lawn mower is to be stored for a pe-
riod 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.
HANDLE
You can fold your lawn mower handle for
storage.
NOTE: The upper handle has an "anti-fold"
bracket located on the right side of the
handle. This bracket prevents the upper
handle from folding forward, which helps
protect control cable(s) from damage.
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 upper handle 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
automatically lock into the mowing posi-
tion.
CARBURETOR
Your carburetor has a non-adjustable
fixed main jet for mixture control. 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 and/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 set-
ting can be dangerous. If you think the
engine-governed high speed needs adjust-
ing, contact a Sears or other qualified ser-
vice center, which has proper equipment
and experience to make any necessary
adjustments.

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.
Also, 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.
