IMPORTANT: This cutting machine is capable of amputating hands and feet and
throwing objects. Failure to observe the following safety instructions could result in
serious injury or death.
I.GENERAL OPERATION
• Read, understand, and follow all
instructions on the machine and in the
manual(s) before starting. Be thor-
oughly 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
discharge 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 the
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
barefoot 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.
•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
2approved by the manufacturer.

• Stopthe 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

II. SLOPE OPERATION
Slopes are a major factor related to slip
and 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. Exemise 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.
II1. CHILDREN
Tragic accidents can occur if the operator
is not alert to the presence of children.

BEFORE STARTING ENGINE
ADD OIL
Your lawnmower is shipped without oil in
the engine. Engine holds 20 oz. of oil.
For type and grade of oil to use, see
"ENGINE" in Maintenance section of this
manual.
1. Be sure lawnmower is level and area
around oil fill is clean.
2. Remove engine oil cap and fill to the
full line on the dipstick. Pour oil slowly.
Do not over fill.
NOTE: Allow oil to settle down ,into engine
for accurate reading. To read proper level,
tighten engine oil cap, then remove it to
read the dipstick.
3. Reinstall engine oil cap and tighten.
• 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.
ADD GASOLINE
•Fill fuel tank. Use fresh, clean, regular
unleaded gasoline with a minimum of
87 octane. Do not mix oil with gaso-
line. Purchase fuel in quantities that
can be used within 30 days to assure
fuel freshness.
AWARNING: Experience indicates that
alcohol blended fuels (called gasohol or
using ethanol or methanol) can attract
moisture which leads to separation and
formation of acids dudng 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. Drain 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 Instructionsfor
additional information. Never use engine
or carburetor cleaner products in the fuel
tank or permanent damage may occur.
CAUTION: Fill to bottom of gas tank
filler neck. Do not overfill. Wipe off any
spilled oil or fuel. Do not store, spill or
use gasoline near an open flame.

•Keep top ofengine aroundstarterclear

Thiswillhelpengine air flowand
extend engine life.
MULCHING MOWING TIPS
IMPORTANT: For best performance,
keep mower housing free of built-up
grass and trash. Clean UNDERSIDE OF
MOWER HOUSING after each use. See
"Cleaning" in 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 recutting 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 and the newly cut area will not be
exposed to the direct sun.
• 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 mulching, reduce your
width of cut, mow slowly and raise
the rear of the lawn mower one wheel
adjuster setting higher than the front.
• 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 or perpendicu-
lar 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.

•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
shortened engine life.
_I_CAUTION: 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 where it cannot come
in contact with plug.

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 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 adjust-
ment.
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.
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
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
section of this manual).
2. Lubricate as shown in the Mainte-
nance 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.
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.

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, expedence indicates that 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.
1. Drain the fuel tank.
2. Start the engine and let it run untilthe
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.
NOTE: Fue! stabilizer is an acceptable
alternative in minimizing the formation of
fuel gum deposits dudng storage. Add
stabilizer to gasoline in fuel tank or
stoi'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 carburetor, Do not drain the gas tank
and carburetor if using fue! 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 one ounce (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 give protection 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 conden-
sation to form and will cause your unit
to rust.
IMPORTANT: Never cover mower while
engone and exhaust areas are still
warm.
d_ 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.
