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. 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.
II1.CHILDREN
Tragic accidents can occur if the operator
is not alert to the presence of children.
Children are often attracted to the

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 setlle 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 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. 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 Instructions for
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.
Engine oil cap Gasoline filler cap
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.
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.

TO STOP ENGINE
•To stop engine, release operator
presence control bar.
NOTE: In cooler weather it may be
necessary 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 attempting to start and do not
repeat priming steps.
MOWINGTIPS
•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
cutting conditions, the engine speed
should be set in the fast position.
•When using a rear discharge lawn
mower in moist, heavy grass, clumps of
cut grass may not enter the grass
catcher. Reduce ground speed
(pushing speed) and/or run the lawn
mower over the area a second time.
• If a trail of clippings is left on the right
side of a rear discharge mower, mow in
a clockwise direction with a small
overlap to collect the clippings on the
next pass.
• 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 MOWINGTIPS
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 net 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 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 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.

TO SHARPEN BLADE
NOTE: We do not recommend sharpen-
ing 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
• The grass catcher may be hosed with
water, but must be dry when used.
• Check your grass catcher often for
damage or deterioration. Through
normal use it will wear. If catcher
needs replacing, replace only with a
manufacturer approved replacement
catcher. Give the lawn mower model
number when ordering.
DRIVE WHEELS
Check front drive 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 area and must be cleaned to free
drive wheels.
If necessary to clean the drive wheels,
check both front wheels.
1. Remove hubcaps, hairpin cotters and
washers.
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.
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 SF-SJ.
Select the oil's SAE viscosity grade
according to your expected operating
temperature.
NOTE: Although multi-viscosity oils
(5W30, 10W30 etc.) improve starting in
cord 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
bevel,

grass and trash. Clean the underside of
your mower after each use.
41_CAUTION: Disconnect spark plug wire
from spark plug and place wire where it
cannot come in contact with the spark
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
shortened engine life.
CLEAN UNDER DRIVE COVER
Clean under drive cover at least twice a
season. Scrape underside of cover with
putty knife or similar loci to remove any
build-up of trash or grass on underside of
drive cover.

ENGINE
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•

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

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, experience 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. Stad the engine and let it run until the
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: Fuel stabilizer is an acceptable
alternative in minimizing the formation of
fuel gum deposits during storage. Add
stabilizer to gasoline in fuel tank or
storage 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 fuel stabilizer.
ENGINEOIL
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 protec-
tive cover that does not retain moisture.
Do not use plastic. Plastic cannot
breathe, which allows condensation to
form and will cause your unit to rust.
IMPORTANT: Never cover mower while
engone and exhaust areas are still warm.
,_ 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.
