2
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. 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 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.
3
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.
&WARNING: 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 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 itwill 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.
,_ 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.

Gasoline filler cap
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.

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 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.
MAX 1/3
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").

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 rubber.
Avoid stumps, stones, deep ruts, sharp
objects and other hazards that may cause tire damage.
DRIVE WHEELS Check rear drive wheels each time before
you mow to be sure they move freely.
The wheels not turning freely means trash,
grass cuttings, etc. are inthe drive wheel area and must be cleaned to free drive wheels.
If necessary to clean the drive wheels, be sure to clean both rear wheels.
BLADE CARE
For best results, mower blade must be kept sharp. Replace a bent or damaged blade.
A 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 haz- ardous, 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).
6. Remove debris shield.
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 blade adapter on engine crank-
shaft. Be sure key in adapter and crank- shaft keyway are aligned; and that drive
belt is inside tabs of belt retainer.
2. Install debris shield.
3. Position blade on the blade adapter.
IMPORTANT: To ensure proper assembly, center hole in blade must align with star on blade adapter.
4. Be sure the trailing edge of blade (oppo- site sharp edge) is up toward engine.
5. Install the blade bolt with the lock washer and hardened washer into
blade adapter and crankshaft.
6. 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. Ibs.
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 blade is bal-
anced. An unbalanced blade will cause eventual damage to 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, 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.
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.

F -20 0 30 32 40 60 80 100
c -_o -2; -1; ; 1'o _o 10 4;
TEMPERATURE RANGE ANTICIPATED BEFORE NEXT OIL CHANGE
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.
.
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, 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.
_I,CAUTION: 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

CLEANING
IMPORTANT: For best performance, keep mower housing free of built-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.
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 dean.
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.
