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
NOTE: Before filling fuel tank, remove
and discard the debris plug that Is inside
the tank.
• Fill fuel tank. Use fresh, dean, 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.
^WARNING: 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
filter neck. Do not overfill. Wipe off any
spilled oil or fuel. Do not store, spill or
use gasoline near an open flame.

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.
MOWING TIPS
• 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.
• 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
IMPO RTANT: For best perfo rmance,
keep mower housing free of built-up
grass and trash. See "Cleaning" in
MAINTENANCE section of this manual.
• The special mulching blade will recut
the grass clippings many times and
reduce them in si2e 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 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.

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.
STORAGE
CARBURETOR
Your carburetor is not adjustable. 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

ENGINE
FUELSYSTEM
IMPORTANT; It is important to prevent
gum deposits from forming in essentiai
fuel system parts such as carburetor, fuei
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. Start 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.
ENGINE OtL
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. Rost 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 ailows conden
sation to form and will cause your unit
to rust.
IMPORTANT: Never cover mower while
engone and exhaust areas are still
warm.
A 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.
