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 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.
II. 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.
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. A/everassume
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.
• 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.
V. GENERAL SERVICE
• 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
spillage. 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.
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.
Maintain or replace safety and instruc
tion labels, as necessary.
AWARNING: This lawn mower is equipped with an internal combustion engine and
should not be used on or near any unimproved forest-covered, brush-covered or
grass-covered land unless the engine’s exhaust system is equipped with a spark
arrester meeting applicable local or state laws (if any). If a spark arrester is used, it
should be maintained in effective working order by the operator.
In the state of California the above is required by law (Section 4442 of the California
Public Resources Code). Other states may have similar laws. Federal laws apply on
federal lands. A spark arrester for the muffler is available through your nearest Sears
Parts & Repair Center (See the REPAIR PARTS section of this manual).

BEFORE STARTING ENGINE
ADD OIL
Your I awn mower 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.
A 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.
NOTE: Your engine is equipped with an
automatic choke system. No priming or
choking is required before starting.
• To start engine, hold operator presence
control bar down to the handle and pull
starter handle quickly. Do not allow
starter rope to snap back.
10
MOWING TIPS
A 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.
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.

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

or on a grinding wheel. Do not attempt
to sharpen while on the mower.
• To check blade balance, you will need a
5/8" diameter steel bolt, pin, or a cone bal
ancer. (When using a cone balancer, follow
instructions supplied with balancer.)
NOTE: Do not use a nail for balancing
blade. The lobes of the center hole may
appear to be centered, but are not.
• Slide blade on to an unthreaded portion
of the steel bolt or pin and hold the
bolt or pin parallel with the ground. 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.
SAE VISCOSITY GRADES
30 32 40 60 80 100
TEMPERATURE RANGE ANTICIPATED BEFORE NEXT OIL OHANGE
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.
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.
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, which
ever 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.
ACAUTION: 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.

Back plate
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 SPECIFICATIONS”
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.
ACAUTION: 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.
WATER WASHOUT FEATURE
Your lawn mower is equipped with a fitting
that allows quick and easy cleaning of
the underside of the housing. To use this
feature, proceed as follows:
1. Move lawn mower to an area of cut
grass or another hard surface.
NOTE: Water, grass and other debris will
drain from beneath the mower housing
during the washout process.
2. Remove grass catcher and discharge
chute assembly from lawn mower.
3. Close mulcher door (if equipped).
4. Connect a garden hose to the fitting
where shown.
IMPORTANT: Be sure the garden hose is
not routed under the lawn mower housing
or entangled in the wheels.
5. Turn on water supply and check for
leaks at the fitting.
If no leaks are present, start engine (as
described in the Operation section of
this manual) and let engine run until the
underside of the lawn mower is clean.
A WARNING: Do not engage the drive
system during the washout process.
6. Shut off the engine.
7. Shut off water supply and remove
hose from fitting.
CAUTION: Do not remove hose from
fitting while engine is running. Water in
engine can result in shortened engine life.
8. Start engine (as described in the Op
eration section of this manual) and let
engine run for a full minute to remove
excess water from mower.
CLEAN UNDER DRIVE COVER
Clean under drive cover at least twice a
season. Scrape underside of cover with
putty knife or similar tool to remove any
build-up of trash or grass on underside of
drive cover.
