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.

AWARNINO: 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.

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 pdmer

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 ovedoading 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 e 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.

• For side discharge lawn mowers;

cutting in a counter-clockwise direction,
starting at the outside of the area to be

cut, spreads grass clippings more
evenly and puts less load on the
engine. To keep clippings off of
walkways, flower beds, etc,, make the

first cuts in a clockwise direction.

• 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

MAINTENANCE section of this manual.

• The special mulching blade will recur

the grass clippings many times and
reduce them in size so that as they fall
ontothe 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 recurring 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 eady

afternoon. At this time the grass has
dried and the newly cut area will not be
exposed 1o 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 abd 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.

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 mower as

instructed in this manual.
Some adjustments will need to be made

periodically to properly maintain your
unit.

All adjustments in the Service and
Adjustments section of this manual

should be checked at least once each
season.

• 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

assures proper air-fuel mixture and
helps your engine run better and last
longer.

• Follow the maintenance schedule in
this manual.

BEFORE EACH USE

1. Check engine oil level.

2. Check for loose fasteners.

LUBRICATION
Keep unit well lubricated (See "LUBRI-

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
cold weather, these mutti-viscosity oils

will result in increased oil consumption

' when used above 32°F. Check your

engine oil level more frequently to avoid

pessib_e engine damage from running
low on oil.

Change the oil after every 25 hours of
operation or at least once a year if the

ENGINE SPEED
Your engine speed has been factory set.

Do not attempt to increase engine speed
or it may result inpersonal 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 an authorized service

center for repeir andJor adjustment.
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.

14

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 (Sea

"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.

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.

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 alcohoT

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.

ENGINEOIL
Drain oil (with engine warm) and replace

with clean engine oil. (See "ENGINE" in
the Maintenance section of this manual),

15

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.

live cover that does not retain mois-
ture. 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
stodng in any enclosure.
