OPERATMON
BEFORE USING YOUR LAWN MOWER, AGAIN REFER TO THE "SAFETY RULES" AS SHOWN ON PAGE 2
OF THIS MANUAL° ALWAYS BE CAREFUL
The operation of any lawn mower can result in foreign objects being thrown into the
eyes, which can result in severe eye damage Always wear safety glasses or eye
shields before starting power tool operation or while performing any adjustments or
repairs. We recommend Wide Vision Safety Mask for over spectacles or standard
glasses available at Sears Retail or Catalog Stores..
HOWTOUSEYOURMOWER
TO STOP ENGINE
Release blade control handle to stop engine.
Disconnect the spark plug wire and move it away from
the spark plug to prevent accidental starting while
equipment is unattended.
ENGINE SPEED CONTROL
The engine speed is controlled by a lever (red knob)
located on the left side of the engine_ The "HI" posi-
tion is for starting engine, normal cutting and best per-
formance The "LOW" position is for light cutting, trim-
ming and fuel economy
BLADE CONTROL HANDLE
Your mower has a control handle which requires the
operator to be behind the handle to start and run the
mower When the operator releases the control han-
dle, the engine will stop and an internal brake helps
the blade to stop quickly.
When the operator leaves the operating position to
change the cutting height, pick up sticks or other
objects in the way, the engine will stop automatically
when the control handle is released.
DRIVE CLUTCH CONTROL
To engage the wheel drive, hold the drive clutch con-
trol against the handle. Releasing the drive clutch
control stops the wheels from driving. Release the
drive clutch control to slow down when negotiating an
obstacle, making a turn or stopping
SHIFT LEVER
The five speed shift lever is located on the left side of
the mower, beside the engine. See figure 7. To select
the mower speed, depress the lever, move to desired
position and release the lever. Position 1 is the slow-
est speed; position 5 is the fastest
eTo change cutting height, move adjuster levers
toward wheel& See figure 7. Move wheels up or
down to suit your requirements Be sure all four
levers are in the same setting
eAdjust cutting height to suit your requirements..
Refer to the "Mulching or Mowing Tips" on page 9.
(The height adjusters may seem hard to move when
new. They will operate easier after some use )

OIL
A 20 ounce bottle of SAE 30 oil is included with your
new lawn mower_
Only use high quality detergent oil rated with API ser-
vice classification SG. Select the oil's viscosity grade
according to your expected operating temperature_
Colder ._ 32°F _ _ Warmer
WARNING: TO AVOID PERSONAL
INJURY, DO NOT MOVE THE SHIFT
LEVER WHEN THE ENGINE IS RUNNING. 5W30 m SAE 30
ADJUST CUTTING HEIGHT
Each wheel has an adjuster lever to set the cutting
height on your mower. They should always be set to the
same position.
eRaise wheels for low cut and lower wheels for high
cut
NOTE: Although multi-viscosity oil (5W30, 10W30,
etc,) improve starting in cold weather, these multi-vis -
cosity oils will result in increased oil consumption
when used above 32°E Check your oil level more fre-
quently to avoid possible engine damage from run-
ning low on oil.

OPERATION
e Place unit so engine is in a level position
e Remove oil fill cap and dipstick assembly Pour oil
slowly until oil level is to the FULL mark on dipstick
Crankcase capacity is approximately 1-1/4 pints
(20 ounces). DO NOT OVERFILL
NOTE: Crankcase oil should be changed after first
two (2) hours of operation and every twenty-five (25)
hours thereafter. Refer to ENGINE LUBRICATION
section.
eReplace oil fill cap and dipstick Tighten cap securely.
GAS
e Fill gas tank with about one (1) quart of clean,
fresh, lead-free grade automotive gasoline_ Low-
lead or regular gasoline is an acceptable substitute.
DO NOT use Ethyl or high octane gasoline Be cer-
tain container is clean and free from rust or foreign
particles Never use gasoline that may be stale
from long periods of storage in the container_
WARNING: EXPERIENCE INDICATES THAT ALCO-
HOL 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 FOR
30 DAYS OR LONGER° USE FRESH FUEL NEXT
SEASON. SEE "STORAGE" SECTION FOR ADDI-
TIONAL INFORMATION.
NEVER USE ENGINE OR CARBURETOR CLEAN-
ER PRODUCTS IN THE FUEL TANK OR PERMA-
NENT DAMAGE MAY OCCUR.

MULCHINGORMOWINGTiPS
eFor best results in normal and heavy mowing,
always run engine in "HI" speed position. "LOW"
speed is only for light cutting, trimming and fuel
economy.
@The grass condition at the time of mewing deter-
mines the proper mower cutting height setting for
best lawn appearance. For a healthy lawn, always
cut one-third or less of the total length of the grass
at any one cutting.
0Under 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
eFor extremely heavy cutting, use a slow ground
speed, and reduce the width of cut.
eUnder heavy conditions cross cut for additional
mulching of surface debris.

ENGINE OIL RECOMMENDATIONS
A 20 ounce bottle of SAE 30 oil is included with your
new lawn mower
Only use high quality detergent oil rated with API ser-
vice classification SG. Select the oil's viscosity grade
according to your expected operating temperature.
Colder -,_ 32°F _=- Warmer
5W30 [] SAE 30
NOTE: Although multi-viscosity oil (5E30, 10W30,
etc.) improves starting in cold weather, these multi-
viscosity oils will result in increased oil consumption
when used above 32 ° F_ Check your oil level more
frequently to avoid possible engine damage from run-
ning low on oil
WHEELS
DO NOT oil or grease the wheel bearings_ Viscous
lubricants will attract dust and dirt that will shorten the
life of the self-lubricating wheel bearings. If you feel
the wheels must be lubricated, use only a dry, silicone
type lubricant sparingly_
WHEEL ADJUSTERS
For easy operation, lubricate the wheel adjusters at
least once a season with light oil.
BRAKE SPRING BRACKET
Spray a light oil lubricant on the brake spring bracket,
located on the right rear corner of the engine, at least
once a season.
TRANSMISSION
The transmission is pre-lubricated and sealed at the
factory. It does not require checking. If disassembled
for any reason, fill with 2 ounces of Alvania grease,
part number 737-0168.
e Use a block of wood between blade and mower
deck to prevent blade from turning when bolt is
removed. Protect your hands with gloves and/or
wrap blade with heavy cloth
Remove blade bolt by turning counterclockwise
Use a 9/16" box or open-end wrench
TO REPLACE BLADE (See Figure 11):
ePut blade adapter on engine crankshaft
eFit blade in adapter. Be sure trailing edge of blade
is up towards engine.
eAssemble bolts, washers, and nuts in the exact
order of removal.
QUse block of wood to hold blade and tighten bolt
clockwise. The recommended torque for the center
is 450-600 in. Ibs. The recommended torque for the
blade adapter bolts is 200-350 in. IbsTorque
wrenches are available at most Sears stores and
through the catalog.
IMPORTANT: THE BOLT USED TO SECURE THE
BLADE TO ENGINE IS SPECIALLY HEAT-TREATED.
DO NOT SUBSTITUTE (SEE REPAIR PARTS).
CAUTION: A LOOSE BLADE CAN BE
DANGEROUS AND MAY MAKE THE
ENGINE HARD TO START,
Use only a Sears authorized replacement blade to get
the best cutting results.

eTurn mower on its side. Make sure air filter and
carburetor are up.
eCare should be taken to keep the blade balanced.
An unbalanced blade will cause excessive vibration
when running and eventual damage to mower and
engine
10

CUSTOMER RESPONSIBILITIES
eTo 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, blade is not balanced. Sharpen
the heavy end until the blade is balanced.

WIRE WHERE IT CANNOT COME IN CON-
TACT WITH THE SPARK PLUG,
Turn mower on its side with carburetor and air filter
up.
Clean the underside of your mower after each use
by scraping to remove build-up of grass clippings,
leaves, dirt or other matter. If this debris is allowed
to accumulate, it will invite rust and corrosion, and
may prevent proper mulching
Clean your mower and engine often to keep build-
up of grass or debris from accumulating around
engine. A clogged engine runs hotter and shortens
engine life.
NOTE: We DO NOT recommend using a garden hose
to clean mower unless the electrical system, muffler,
air filter and carburetor are covered to keep water out.
Water in engine can result in shortening engine life.

STORAGE
Your mower and engine should be prepared for off-
season storage as follows:
MOWER
e Clean underside of mower housing (See "CLEAN-
ING" in "Customer Responsibilities" section of
manual).
e Inspect and replace/sharpen blade, if required (See
"BLADE CARE" in "Customer Responsibilities"
section of manual).
e Lubricate as shown in "Customer Responsibilities"
section of manual.
HANDLE
•You can fold your mower's handle for storage as
shown in figure 14. Remove the starter rope from
the rope guide. Loosen the two hand knobs on the
sides of the handle, and let the upper handle fold
down to the rear Move the hairpin clips to the outer
hole in the weld pins on the handle mounting brack-
ets. Refer to figure 3 Spread the sides of the lower
handle, and push itforward and down.
IMPORTANT: WHEN FOLDING HANDLE FOR
STORAGE OR TRANSPORTATION, BE CAREFUL
NOT TO BEND OR KINK THE CABLES.
FIGURE 14.
eTo place the handle in the operating position, refer to
"Assembly" on page 5 of this manual.
To prevent engine damage if lawn mower is not used
for more than 30 days, proceed as follows.
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, FUEL (CALLED GASOHOL OR
USING ETHANOL OR METHANOL) CAN ATTRACT
MOISTURE WHICH LEADS TO SEPARATION AND
FORMATION OF ACID DURING STORAGE. ACIDIC
GAS CAN DAMAGE THE FUEL SYSTEM OF AN
ENGINE WHILE IN STORAGE
NOTE: Fuel stabilizer is an acceptable alternative in
minimizing formation of fuel gum deposits during stor-
age. Add stabilizer to gasoline in fuel tank in fuel tank
or storage container. Always follow mix ratio found on
stabilizer container. Run engine at least 10 minutes
after adding stabilizer to allow stabilizer to reach the
carburetor. Do not drain gas tank and carburetor if
using stabilizer.
eDrain the fuel tank Start the engine, and let it run
until fuel lines and carburetor are empty
e When storing the mower at the end of the season,
change the engine oil. Drain the oil after the engine
has been operated and is still warm, and refill the
crankcase with fresh oil
e Lubricate the piston/cylinder area by first removing
the spark plug and squirting clean engine oil into
the spark plug hole. Then cover the spark plug hole
with a rag to absorb oil spray. Next, rotate the
engine by pulling the starter two or three times
Finally, reinstall spark plug and attach spark plug
wire.
OTHER
eDo not store gasoline from one season to another
eReplace your gasoline can if your can starts to rust.
Rust and/or dirt in your gasoline can cause prob-
lems..
eDo not store your mower under any plastic cover.
Plastic cannot breathe which allows condensation
to form and cause the metal components of your
mower to rust.
