I. CHILDREN
WARNING: CHILDREN CAN
BE SERIOUSLY INJURED OR
&
The American Academy of Pediatrics rec-
ommends that children be a minimum of
12 year of age before operating a pedes-
trian controlled lawn mower and a mini-
mum of 16 years of age before operating a
riding lawn mower.
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 mowing area
and under the watchful care of a respon-
sible adult other than the operator.
• Be alert and turn machine off if children
enter the area.
• Before and while walking backwards,

(motor) is running.
• Be sure the area is clear of other people
before mowing. Stop machine if anyone
enters the area.
• Do not operate machine barefooted or
while wearing sandals. Always wear
substantial footwear with good ankle
support while mowing.
• 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 blade when crossing gravel
surfaces.
• Do not operate the mower without
proper guards, plates, grass catcher or
other safety protective devices in place.

III, SLOPE OPERATION
Slopesare a majorfactorrelatedto slip &
fall accidents,which can result in severe
injury.All slopes requireextra 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, bumps or hidden
objects. Uneven terrain could cause a
slip and fall accident. Tall grass can hide
obstacles.
DO NOT:
• Do not mow near drop-offs, ditches or
embankments. You could lose your foot-
ing or balance.
• Do not mow on wet grass or excessively
steep slopes. Poor footing could cause
a slip and fall accident.
IV. SAFE HANDLING OF GASOLINE
To avoid personal injury or property dam-
age, use extreme care in handling gaso-
line. 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 acciden-
tal starting.
• Keep all nuts and bolts tight to be sure
the equipment is in safe working condi-
tion.
• Never tamper with safety devices.
Check their proper operation regularly.
Never do anything to interfere with the
intended function of a safety device
or reduce the protection provided by a
safety device.
• 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-
4 tion labels, as necessary.

HOW TO USE YOUR LAWN MOWER
ENGINE SPEED
Engine speed was set at the factory for
optimum performance. It is not adjustable.
ENGINE ZONE CONTROL
_ILCAUTION: 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 holding
the operator presence control bar down
to the handle and pulling either drive
control lever rearward to the handle.
The further toward the handle a lever is
pulled, the faster the unit will travel.
• Forward motion will stop when either
the operator presence control bar or a
drive control lever are released. To stop
forward motion without stopping engine,
release a 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 mower forward slightly to disengage
drive wheels.
Operator presence control bar
DRIVE CONTROL ADJUSTMENT
Over time, the drive control system may
become "loose", resulting in decreased
speed. There is a turnbuckle on 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. Rotate turnbuckle on drive control to
increase drive speed.
3. Operate mower to test drive speed.

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.
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.
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.

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
,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.
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.

• Avoid stumps, stones, deep ruts, sharp
objects and other hazards that may
cause tire damage.
DRIVE WHEELS
Check 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
or dust cover area and must be cleaned to
free drive wheels.
If necessary to clean the drive wheels, be
sure to clean all wheels.
1. Remove hubcaps, Iocknuts, and wash-
ers.
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.
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 hard-
ware (bolt, lock washer and hardened
washer).
6. Remove debris shield.
NOTE: Remove the blade adapter and
check the key
inside hub of blade adapter. 13appear to be centered, but are not.
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;
and that the drive belt is inside the tab
of the 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 (op-
posite sharp edge) is up toward the
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.

TO SHARPEN BLADE
NOTE: We do not recommend sharpening
blade - but if you do, be sure the blade is
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, you will need a
5/8" diameter steel bolt, pin, or a cone
balancer. (When using a cone balancer,
follow the instructions supplied with it.)
NOTE: Do not use a nail for balancing
blade. The lobes of the center hole may
Slide bladeon to an unthreadedportion
of the steel boltor pin and hold the
bolt orpin parallelwiththe ground. If
bladeis balanced,it shouldremain in a
horizontalposition. If eitherend ofthe
blademoves downward,sharpenthe

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.
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 en-
gine 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.
GEAR CASES
• To keep your drive system working
properly, the gear cases 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 cases are 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.
SAE VISCOSITY GRADES
F -20 0 30 32 40 60 80 100
C -30 -20 -1; ; 1'0 20 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°R Check your engine oil
level more frequently to avoid possible
engine damage from running low on oil.
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.

CLEANING
IMPORTANT: For best performance, keep
mower housing free of built-grass and
trash. Clean the underside of your mower
after each use.
AI:;LCAUTION: Disconnect spark plug wire
from spark plug and place wire where it
cannot come in contact with plug.
• Clean the underside of your mower by
scraping to remove build-up of grass/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.
• With the exception of the water washout
port (if equipped), we do not recommend
using a garden hose to clean the outside
of your lawn mower unless the electrical
system, muffler, air filter and carburetor
are covered to keep water out. Water in
engine can result in shortened engine life. 15
WATER WASHOUT FEATURE
