propel the tiller forward. If this occurs,
let go of the handlebars and do not
restrain the machine.
as specified by the manufacturer for all
units with electric drive motors or elec-
tric starting motors.
• Never attempt to make any adjustments
while the engine (motor) is running (ex-
cept where specifically recommended
by manufacturer).
OPERATION
• Do not put hands or feet near or under
rotating parts.
• Exercise extreme caution when operat-
ing on or crossing gravel drives, walks,
or roads. Stay alert for hidden hazards
or traffic. Do not carry passengers.
• After striking a foreign object, stop the
engine (motor), remove the wire from
the spark plug, thoroughly inspect the
tiller for any damage, and repair the
damage before restarting and operating
the tiller.
MAINTENANCE AND STORAGE
• Keep machine, attachments, and ac-
cessories in safe working condition.
• Check shear pins, engine mounting
bolts, and other bolts at frequent inter-
vals for proper tightness to be sure the
equipment is in safe working condition.

CHECK ENGINE OIL LEVEL
TURNING
The engine in your unit has been shipped,
from the factory, already filled with SAE 30
summer weight oil.
1. With engine level, clean area around
oil filler plug and remove plug.
2. Engine oil should be to point of over-
fl o w ing when engine is level.
• For approximate capacity see “PROD-
UCT SPECIFICATIONS” on page 3 of
this manual. All oil must meet A.P.I.
Service Classification SF-SJ.
• For cold weather operation you should
change oil for easier starting (See oil
viscosity chart in the Maintenance sec-
tion of this manual).
• To change engine oil, see the Mainte-
nance section in this manual.
1. Release the drive control bar.
2. Move throttle control to “SLOW” posi-
tion.
3. Place shift lever indicator in “F” (for-
ward) position. Tines will not turn.
4. Lift handle to raise tines out of ground.
5. Swing the handle in the opposite
direction you wish to turn, being careful
to keep feet and legs away from tines.
6. When you have completed your turn-
around, release the drive control bar
and lower handle. Place shift lever in
(till) position and move throttle control
to desired speed. To begin tilling, hold
drive control bar against the handle.
OUTER SIDE SHIELDS
The back edges of the outer side shields
are slotted so that the shields can be
raised for deep tilling and lowered for
shallow tilling to protect small plants from
being buried.
Oil Fill
1. Loosen nut “A” in slot and nut “B”.
2. Move shield to desired position (both
sides).
3. Retighten nuts.
Oil Filler Plug
Oil Drain Plug
TO TRANSPORT
CAUTION: Before lifting or transporting,
allow tiller engine and muffler to cool. Dis-
connect spark plug wire. Drain gasoline
from fuel tank.
ADD GASOLINE
• Fill fuel tank to bottom of filler neck. Do
not overfill. Use fresh, clean, regular
unleaded gasoline with a minimum of
87 octane. (Use of leaded gasoline will
increase carbon and lead oxide depos-
its and reduce valve life). Do not mix oil
with gasoline. Purchase fuel in quan-
tities that can be used within 30 days to
assure fuel freshness.
AROUND THEYARD
1. Release the depth stake pin. Move
the depth stake down to the top hole
for transporting the tiller. Place depth
stake pin in hole of depth stake to lock
in position. This prevents tines from
scuffing the ground.
2. Place shift lever indicator in “F” (for-
ward) position for transporting.
3. Hold the drive control bar against the
handle to start tiller movement. Tines
will not turn.
CAUTION: Fill to within 1/2 inch of top
of fuel tank to prevent spills and to allow
for fuel expansion. If gasoline is acci-
dentally spilled, move machine away from
area of spill. Avoid creating any source of
ignition until gasoline vapors have disap-
peared.
Wipe off any spilled oil or fuel. Do not
store, spill or use gasoline near an open
flame.
IMPORTANT: When operating in temper-
atures below32°F(0°C), use fresh, clean
winter grade gasoline to help insure good
cold weather starting.
4. Move throttle control to desired speed.
AROUND TOWN
1. Disconnect spark plug wire.
2. Drain fuel tank.
3. Transport in upright position to prevent
oil leakage.
BEFORE STARTING ENGINE
IMPORTANT: Be very careful not to allow
dirt to enter the engine when checking or
adding oil or fuel. Use clean oil and fuel
and store in approved, clean, covered
containers. use clean fill funnels.

CAUTION: Alcohol blended fuels (called
gasohol or using ethanol or methanol) can
attract moisture which leads to separa-
tion 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.
See “TO ADJUST CARBURETOR” in the
Service and Adjustments section of this
manual.

TO START ENGINE
TILLING HINTS
CAUTION: Keep drive control bar in
“DISENGAGED” position when starting
engine.
When starting engine for the first time or if
engine has run out of fuel, it will take extra
pulls of the recoil starter to move fuel from
the tank to the engine.
1. Make sure spark plug wire is properly
connected.
2. Move shift lever indicator to “N” (neu-
tral) position.
CAUTION: Until you are accustomed
to handling your tiller, start actual field
use with throttle in slow position (mid-way
between “FAST” and “IDLE”).
• Tilling is digging into, turning over, and
breaking up packed soil before plant-
ing. Loose, unpacked soil helps root
growth. Best tilling depth is 4" to 6". A
tiller will also clear the soil of unwanted
vegetation. The decomposition of this
vegetable matter enriches the soil.
Depending on the climate (rainfall and
wind), it may be advisable to till the soil
at the end of the growing season to
further condition the soil.
• Soil conditions are important for proper
tilling. Tines will not readily penetrate
dry, hard soil which may contribute to
excessive bounce and difficult handling
of your tiller. Hard soil should be mois-
tened before tilling; however, extremely
wet soil will “ball-up” or clump during till-
ing. Wait until the soil is less wet in order
to achieve the best results. When tilling
in the fall, remove vines and long grass
to prevent them from wrapping around
the tine shaft and slowing your tilling
operation.
• You will find tilling much easier if you
leave a row untilled between passes.
Then go back between tilled rows.There
are two reasons for doing this. First,
wide turns are much easier to negoti-
ate than about-faces. Second, the tiller
won’t be pulling itself, and you, toward
the row next to it.
• Do not lean on handle. This takes
weight off the wheels and reduces
traction. To get through a really tough
section of sod or hard ground, apply
upward pressure on handle or lower the
depth stake.
3. Place throttle control in “FAST” posi-
tion.
5. Move choke control to choke position.
5. Grasp recoil starter handle with one
hand and grasp tiller handle with other
hand. Pull rope out slowly until engine
reaches start of compression cycle
(rope will pull slightly harder at this
point).
6. Pull recoil starter handle quickly. Do
not let starter handle snap back
against starter.
NOTE: If engine fires but does not start,
move choke control to half choke posi-
tion. Pull recoil starter handle until engine
starts.
7. When engine starts, slowly move
choke control to “RUN” position as
engine warms up.
NOTE: A warm engine requires less
choking to start.
8. Move throttle control to desired running
position.
9. Allow engine to warm up for a few
minutes before engaging tines.
NOTE: If at a high altitude (3000 feet) or
in cold temperatures (below 32°F), the
carburetor fuel mixture may need to be
adjusted for best engine performance.

ADJUST WHEELS FOR
CULTIVATING
1. Place blocks under right hand side of
tiller and remove hairpin clip and clevis
pin from right hand wheel.
2. Move wheel outward approximately 1

3. Replace clevis pin and hairpin clip on
inside of wheel and remove blocks.
4. Repeat preceding steps on left hand
side.
NOTE: In extremely rough conditions and
while cultivating, the wheels should be
moved outward on the axle for increased
stability.
CULTIVATING
Cultivating is destroying the weeds be-
tween rows to prevent them from robbing
nourishment and moisture from the plants.
At the same time, breaking up the upper
layer of soil crust will help retain moisture
in the soil. Best digging depth is 1" to 3"
(2.5-7.5 cm). Lower the outer side shields
to protect small plants from being buried.
• Cultivate up and down the rows at a
speed which will allow tines to uproot
weeds and leave the ground in rough
condition, promoting no further growth
of weeds and grass.

NOTE: Although multi-viscosity oils
(5W-30, 10W-30, etc.) improve starting in
cold weather, they will result in increased
oil consumption when used above 40°F
(4°C). Check your engine oil level more
frequently to avoid possible engine dam-
age from running low on oil.
Change the oil after every 25 hours of
operation or at least once a year if the tiller
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. Add SAE 30 mo-
tor oil or equivalent. Tighten oil filler plug
securely each time you check the oil level.

TO CHANGE ENGINE OIL
Determine temperature range expected
before oil change. All oil must meet API
service classification SF-SJ.
• Be sure tiller is on level surface.
• Oil will drain more freely when warm.
• Use a funnel to prevent oil spill on tiller,
and catch oil in a suitable container.
1. Remove drain plug.
2. Tip tiller forward to drain oil.
3. After oil has drained completely,
replace oil drain plug and tighten se-
curely.
MUFFLER
Do not operate tiller without muffler. Do
not tamper with exhaust system. Dam-
aged mufflers or spark arresters could
create a fire hazard. Inspect periodically
and replace if necessary. If your engine is
equipped with a spark arrester screen as-
sembly, remove every 50 hours for clean-
ing and inspection. Replace if damaged.
4. Remove oil filler plug. Be careful not to
allow dirt to enter the engine.

SPARK PLUG
CLEANING
Replace spark plugs at the beginning of
each tilling season or after every 50 hours
of use, whichever comes first. Spark plug
type and gap setting is shown in “PROD-
UCT SPECIFICATIONS” on page 4 of this
manual.
Do not clean your tiller when the engine
and transmission are hot. We do not rec-
ommend using pressurized water (garden
hose, etc.) to clean your unit unless the
gasket area around the transmission and
the engine muffler, air filter and carburetor
are covered to keep water out. Water in
engine will shorten the useful life of your
tiller.
TRANSMISSION
Once a season, lubricate the right hand
gear case grease fitting with 1 oz. of EP
#1 grease.
• Clean engine, wheels, finish, etc. of all
foreign matter.
• Keep finished surfaces and wheels free
of all gasoline, oil, etc.
• Protect painted surfaces with auto-
motive type wax.
SERVICE AND ADJUSTMENTS
TIRE CARE
CAUTION: Disconnect spark plug wire

TINE REPLACEMENT
CAUTION: Tines are sharp. Wear
gloves or other protection when handling
tines.
Worn Tine
A badly worn tine causes your tiller to
work harder and dig more shallow. Most
important, worn tines cannot chop and
shred organic matter as effectively nor
bury it as deeply as good tines. A tine this
worn needs to be replaced.

• To maintain the superb tilling perfor-
mance of this machine the tines should
be checked for sharpness, wear, and
bending, particularly the tines which
are next to the transmission. If the gap
between the tines exceeds 3-1/2 inches
they should be replaced or straightened
as necessary.

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 your nearest Sears or
other qualified service center which has
the proper equipment and experience to
make any necessary adjustments.
ENGINE
Maintenance, repair, or replacement of
the emission control devices and systems,
which are being done at the customers ex-
pense, may be performed by any non-road
engine repair establishment or individual.
Warranty repairs must be performed by an
authorized engine manufacturer's service
outlet.
TO ADJUST CARBURETOR
The carburetor has been preset at the
factory and adjustment should not be
necessary. However, engine performance
can be affected by differences in fuel, tem-
perature, altitude or load. If the carburetor
does need adjustment, contact your near-
est Sears or other qualified service center.

STORAGE
Immediately prepare your tiller for storage
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 stor-
age 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 carbu-
retor. Do not empty the gas tank and
carburetor if using fuel stabilizer.
at the end of the season or if the unit will
not be used for 30 days or more.
CAUTION: Never store the tiller 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.
TILLER
1. Clean entire tiller (See “CLEANING” in
the Maintenance section of this man-
ual).
ENGINE OIL
Drain oil (with engine warm) and replace
with clean oil. (See “ENGINE” in the Main-
tenance section of this manual).
CYLINDER
2. Inspect and replace belts, if necessary
(See belt replacement instructions in
the Service and Adjustments section of
this manual).
3. Lubricate as shown in the Maintenance
section of this manual.
4. Be sure that all nuts, bolts and screws
are securely fastened. Inspect moving
parts for damage, breakage and wear.
Replace if necessary.
5. Touch up all rusted or chipped paint
surfaces; sand lightly before painting.
1. Remove spark plug.
2. Pour 1 ounce (29 ml) of oil through
spark plug hole into cylinder.
3. Pull starter handle slowly several 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 protective
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 tiller while en-
gine and exhaust areas are still warm.
ENGINE
FUEL SYSTEM
IMPORTANT: 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, 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.
• Empty the fuel tank by starting the en-
gine and letting 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.
