IMPORTANTTIPSTO HELPYOUR LAWN MOWERSTARTFASTER,RUN AND PERFORMBETTER
1. USE UNLEADED GASOLINE: It burns cleaner and leaves less residue in the engine. Regular gasoline can also be
used. DO NOT use PREMIUM GASOLINE.
2. DRAIN OR RUN-OUT ALL GASOLINE FROM TANK AT THE END OF THE SEASON: DO NOT leave gasoline
in your mower when stored for long periods. It will "GUM" your engine. Run engine until the gasoline runs out.
3. START EACH MOWING SEASON WITH FRESH GASOLINE: DO NOT keep gasoline in your can. If your gasoline
can is starting to rust, replace can.
4. CHANGE YOUR SPARK PLUG EVERY SPRING: An old corroded spark plug prevents fast starting and smooth
running engine.
5. REPLACE YOUR AIR CLEANER OR FILTER OFTEN: Dirt, afong with heat can harm your engine, the cleaner or
filter will clog up, preventing clean air from reaching your engine. See "Air Cleaner/Filter" section of this manual
for replacing air cleaner or filter.
6. USE SAE 30W OIL: DO NOT use SAE !0W40 oil.
7. CHANGE OIL AS RECOMMENDED: IMPORTANT - change oil after the first two (2) hours of use, then every 25
hours of use.
8. REPLACE THE BLADE WHEN NEEDED: You can sharpen the blade, but we do not recommend it. Erosion from
hitting foreign objects can damage the blade. Replace blade with one specifically designed for your mower.
9. AT THE END OF THE SEASON, CLEAN YOUR MOWER: IMPORTANT - first disconnect the spark plug wire_ If
possible, store your mower in a well ventilated area and protected from moisture.
]0. FOLLOW THE MAINTENANCE SUGGESTIONS IN YOUR OWNERS MANUAL: Read your manual and keep
it in a convenient place for easy reference.

maintain proper belt tension. Keep the area around
the gear case clear of trash by removing drive cover
and cleaning (See Fig. t6 and 7_.
3. The gear case is lubricated with multi-purpose
automotive grease. DO NOT USE ANY OTHER type
grease or oil in the gear case. See "GEAR CASE"
under "Maintenancet'.
4. Check your mower, each time you mow, to be sure
that the front wheels turn freely. /f wheels DO NOT
turn freely, remove any trash which may have gotten

MOWING TIPS
1. Under certain conditions it may be necessary to raise
the height of cut to keep from overloading the engine
and leaving clumps af grass clippings.
2. For extremely heavy cutting, make the width of your
cut I/2 to 3/4 the normal cut. Thiswill reduce the load
on the engine and give you cleaner cutting and
bagging.
3. The user should note that when cutting moist, heavy
grass with a rear bagging mower, clumps of cut grass
may fail to enter the grass catcher. To pick up the
clumps ff they occur, run the mower over the area a
second time.
4. Under certain conditions a trail of grass clippings may
be left at the right side of the mower. Mowing in a
clockwise direction with a small overlap will allow
these clippings to be collected on next pass.
MAINTENANCE
Be good to your mower. Once a year put in a new spark
plug, a new air filter and check blade for wear. A new
blade cuts better. With a new spark plug your engine will
start and run better. Aclean air filter assures proper air-
fuel mixture. It will help your engine run better and last
longer.
MOWER:
BLADE/BLADEFLANGECARE
CA UTION: Protect your hands when removing or in-
stalling blade of your mower. Wear heavy gloves
and/or wrap blade with heavy cloth when holding

2. Take blade nut off by turning counter.clockwise. Use
a 15/16" box or open end wrench on the blade nut
(See Fig. !8).
3. Put a block of wood between the blade and mower
hausing to prevent blade rotation when removing and
tightening blade nut.
FIG. 21
NOTE: Always check the blade flange when changing
the blade to be sure tab has not been damaged (See Fig.
19).
4. If the tab in the blade flange is damaged replace the
blade flange.
NOTE: The blade flange with tab attaches the blade to
crankshaft. It isnot intended to protect the crankshaft. The
tab must be in good condition and located in slot of
crankshaft to keep blade attached.
5. Put the blade flange on the engine crankshaft with the
tab in the slot of the crankshaft (See Fig. 19).
6. Put the blade on the crankshaft as shown in (Fig. 19).
Be sure the word "TOP" (stamped in the blade) is
toward the engine.
7. Install the flat washer, two (2) formed washers and
blade nut as removed above.

aLMNTENANCE(CONT'D)
IL M/gLADE FLANGECARE(CONT'D)
NOTE: We recommend that the blade nut be replaced
when installing a new blade.
8. Tighten blade nut. The recommended tightening tar-
clue is 70.75 ft. Ibs. Use block of wood to prevent
blade retation.
NOTE: Torque wrenches are available at most Sears
retail stores and through the catalog.
Aloose blade can result in difficult starting of engine.
We DO NOT recommend sharpening blade . you can
keep the cutting edge touched up with afile. Grinding the
cutting edge excessively can cause the blade to be out
of balance. An unbalanced blade can cause excessive
vibration and shorten the life of the engine and mower.
REARDEFLECTOR
The rear deflector which is attached to the rear of your
mower is to keep objects from being thrown out the back
of the mower. If your rear deflector becomes damaged
you should replace it (See Fig. 22).

MAINTENANCE(CONT'D)
GEARCASE
1. THE GEAR CASE AND AREA AROUND ALL THE
DRIVE SHOULD BE KEPT CLEAN AND FREE OF
BUILD-UP.
2. To check gear case area:
a. Remove the drive cover by removing the two (2)
screws (See Fig. 16). Keep for re-use.
b. Clean trash from around gear case.
c. Put drive cover back, removed in (a) above.
NOTE: The gear case is filled to proper level at the fac-
tory. The only time the lubricant needs attention is ff ser-
vice has been performed on the gear case.
The gear case must be filled with grease after gear case
has been serviced. Use only multi-purpose automotive
grease. Do not substitute.
LUBRICATION
MOWER WHEELS: Lubricating wheels and/or wheel
bearings is not necessary under normal conditions.
Should conditions require lubricaiton, thoroughly clean
wheels and/or wheel bearings and axles and apply a light
coating of dry lubricant.
REAR DOOR HINGE: Put a few drops of the same oil
as used in the engine on hinge points of rear door once
or twice each year {See Fig. 24).
GEAR CASE: The gear case is filled at the factory and
does not require any addition of lubricant, unless the gear
case is opened and service performed. Use only a multi-
purpose automotive grease for refilling after service has
been performed. Approximately 2 7/2 oz. required.
FRONT WHEEL ADJUSTERS: Put a few drops of the
same oil as used in the engine on the front wheel adjusters
once or twice each year (See Fig. 25).
GRASSCATCHER
Check your grass catcher often for damage or deteriora-
tion. Through normal use it will wear. If catcher needs
replacing, replace only with a manufacturer approved
replacement catcher from Sears. Give the mower number
when ordering.
NOTE: The catcher may be hosed with water, but must
be dry when used.
ZOflE/CONTROLLEVER
Put one or two drops of the same oil as used in the engine
between the zone control lever and bracket located on
left rear of engine {See Fig. 26). Do this once or twice
each year.

CLEANING
CAUTION: Disconnectspark plug wire from spark plug
and place wire where it cannot come in contact withthe
spark plug.
1. Turn mower on its side with carburetor up.
2. Clean the underside of your mower by scraping to
remove build-up of grass and trash.
NOTE: We recommend that you clean the underside of
your mower after each use.
3. Clean your mower and engine often to keep build-up
of trash from accumulating around engine; a clog-
ged 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.

FIG. 28
NOTE: On a new engine some oil may be left in the
engine, as each engine is run for operational checks
before shipping.
Use Sears SAE 30W oil or equivalent. SAE lOW30 oil
can also be used. DO NOT use SAE 10W40 oil.
Use only all with automotive classifications SF, SE, SD
or SC markings on oil container.
Using Sears SAE lOW30 oil will assist engine starting
in coal weather.
Running your engine with oil below safe level or with dirty
contaminated oil can contribute to shortening the life of
your engine.
After the first two (2) hours of mowing change the oil, then
change the oil every 25 hours of mowing thereafter. If
you mow under dusty, dirty conditions you may need to
change the oil more often•
TO CHANGEOIL
CA UTION: Disconnect spark plug wire from spark plug
and place wire where it cannot come in contact with the
spark plug.
I. Remove engine oil cap with dipstick, lay aside on a
clean surface. Warm oil drains better.
2. Tip mower on its side as shown in Fig. 27and drain
oil into suitable container. Rock mower back and forth
to remove any oil trapped inside of engine.
3. Wipe off any spilled oil on mower and/or inside of
engine.

dipstick. DO NOT over fill.
5. Reconnect spark plug wire to spark plug.
AIR FILTEE
CAUTION: DO NOT run your engine without aft filter
in place.
I. Your engine will not run properly with a clogged, dirty
air filter.
NOTE: DO NOT wash this type air filter.
2. Replace your air filter each year, more often if you
mow in very dusty, dirty conditions.
Replacement air filter no. 713332 is available at most
Sears retail stores and through the catalog.

SPARKPLUG
Change your spark plug each year.
A new clean spark plug will make your engine start and
run better. Keep your spark plug clean. Set spark plug
gap at .030.
Recommended replacement Sears spark plug no.
7l 33312 or STD367458 are available at most Sears
retail stores and through the catalog.
GENERAL
DO NOT usegasoline left over from previous season. Old
or stale dirty gasoline can cause starting and running
problems.
Replace your gasoline can, ff your old can starts to rust.
DO NOT use rusty gasoline can, rust and/or dirt in your
gasoline can cause problems.
STORAGE
Never store engine with gasoline in tank, indoors or in
closed, poorly ventilated areas where gasoline fumes may
reach an open flame, spark or pilot light as on a furnace,
water heater, or clothes dryer, etc.
It is important to prevent gum deposits from forming in
essential fuel system parts such as the carburetor, fuel
filter, fuel hose, or tank during storage. Also, experience
indicates that alcohol blended fuels(called gasohol or us-
ing 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.
Toavoid engine problems, the fuel system should be emp-
tied before storage of 30 days or longer. Follow these
instructions:
If your engine is not to be used for 30 days or more
prepare as follows:
Drain gasoline from Fuel tank; gasoline in gasoline tank
and carburetor will form deposits and cause problems in
starting and running your engine.
When preparing your mower for storage it is a good time
to service your mower and engine to be ready for the next
mowing season. Replace such parts as mower blade,
spark plug and air filter.
CHANGE OIL: Warm oil drains better.
Drain old oil and replace with fresh clean Sears SAE 30W
oil.
See "To Change Oil'" section under Maintenance.
Remove spark plug and put 2 or 3 tablespoons of off into
spark plug opening and pull starter rope slowly to
distribute oil, installnew spark plug and tighten.
DO NOT PUT ANY ADDITIVES IN OASOLINE OR OIL.
CLEANMOWER/ENGINE
CAUTION: Before cleaning mower, disconnect spark
plug wire and ptace wire where it cannot come in contact
with the spark plug.
Clean around engine and on top of mower. Scrape under-
side of mower using putty knife or similar toot to remove
any build-up of trash or grass on underside of mower
housing.
NOTE: We DO NOT recommend using a water hose to
clean your 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.
CHECKFASTENERS
Check all fasteners and be sure they are tight: tighten
and!or replace any loose or worn Fasteners.
GEASSCATCHER
Check your grass catcher often for damage or deteriora-
tion. Through normal use it wilt wear. If catcher needs
replacing, replace only with a man ufacturer approved
replacement catcher from Sears. Give the mower model
when ordering.
NOTE: The catcher may be hosed with water, but must
be dry when used.
REPLACEBLADE
See "Blade Care" section under Maintenance. Toget the
best cutting results we recommend that you inspect mower
blade for sharpness, wear and damage each year. If
necessary, replace with aSears original equipment blade.
Replacement blade is available at most Sears stores and
through the catalog. Be sure to give your mower model
number when ordering blade.
We DO NOT recommend sharpening blade -you can
keep the cutting edge touched up with a file. Grinding the
cutting edge excessively can cause the blade to be out
of balance. An unbalanced blade can cause excessive
vibration and shorten the life of the engine and mower.
15

STORAGE(CONT'D)
GENERAL
Always store your mower on its wheels. Storing mower
on its side or end may result in difficuh starting.
When removing your mower from storage, fill gasoline
tank with fresh, clean, unleaded, automotive gasoline.
Check and fill oil to proper level.
When starting your engine the first time after being in
storage for extended period, the engine may smoke for
a while until the engine burns any oil or gasoline ac-
cumulated during the storage period.
DO NOT store gasoline from one season to another. Use
up or dispose of any unused gasoline left from the mow-
ing season.
Replace your gasoline can ff your can starts to rust. DO
NOT use rusty gasoline can. Rust and/or dirt in your
gasoline can cause problems.
DO NOT store your mower under any plastic cover,
plastic cannot breathe which promotes condensation and
can cause your mower to rust.
HANDLE FIG, 2_
You can fold your mower handle for storage (See Fig.
29).
When setting-up your handle from storage position the
lower handle will automatically lock into upright position.
Press the handle levers and move handle forward.
