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 F!LL FUNNELS.
• Fiil fuel tank. Use fresh, dean, regular unfeaded
gasoline. (Use of leaded gasoline wiH increase carbon
and lead oxide deposits and reduce valve life.
IMPORTANT: WHEN OPERATING IN TEMPERATURES
BELOW 32“F (0“C). USE FRESH. CLEAN, WINTER
GRADE GASOLINE TO HELP INSURE GOOD COLD
WEATHER STARTING.
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 stor
age 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 section
of this manual for additional information. Never use engine
or carburetor cleaner products in the fuel tank or permanent
damage may occur.
CAUTION: Fill to within 1/2 Inch of top
of fuel tank to prevent spills and to
allow for fuel expansion, if gasoline is
accidentally spilled, move machine
away from area of spill. Avoid creating
any source of Ignition until gasoline
vapors have disappeared.

OPERATION
TO START ENGINE (See Fig. 13)
CAUTION: Keep drive control bar In
A
• Make sure spark plug wire is properly connected.
• Move shift lever indicator to “N" (neutral) position.
• Place throttle control in "FAST position.
• To start a cold engine, place choke control in “CHOKE"
position. A warm engine requires less choking to start.
• Grasp starter handle with one hand and grasp the tiller
with other hand. Pull rope out slowly until engine
reaches start of compression cycle (rope will pull
slightly harder at this point).
• Pull starter handle quickly. Do not let starter handle
snap back against starter.
• .When engine starts, slowly move choke control to
"RUN" position as engine warms up,
• Move throttle control to desired running position,
• Allow engine to warm up for a few minutes before
engaging tines.
NOTE: If at a high altitude (above 3000 feet) or in cold
temperatures (below 32“F), the carburetor fuel mixture
may need to be adjusted for best engine performance. See
"TO ADJUST CARBURETOR" in the SERVICE AND AD
JUSTMENT section of this manual.
“DISENGAGED" position when start
ing engine.
TILLING HINTS
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 planting. Loose, unpacked soii
helps root growth. Best tilling depth is 4" to 6", A tiller
will also ciear 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 im portant for propertllling. Tines wilt
not readily penetrate dry, hard soil which may contrib
ute to excessive bounce and difficuit handling of your
tiller. Hard soli should be moistened before tilling;
however, extremely wet soil wii! “bali-up" or clump
during tilling. Wait until the soil is less wet in order to
achieve the best results. When titling inthefaii, remove
vines and long grass to prevent them from wrapping
around the tine shaft and slowing your tilling operation.
For easier handling of your tiller, leave about 8 inches
of untiiled soil between the first and second tilling
passes. The third pass will be between the first and
second (See Fig. 14).
Do not iean 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.
TINE SHEAR PINS
The tine assemblies on your tiller are secured to the tine
shaft with shear pins (See “TINE REPLACEMENT" in the
Service and Adjustments section of this manual).
If the tiller is unusually overloaded or jammed, the shear
pins are designed to break before internal damage occurs
to the transmission.
• if shear pin(s) break, replace only with those shown in
the Repair Parts section of this manual
12
Page 13
OPERATION
CULTIVATING
Cultivating is destroying the w/eeds between rows to pre
vent 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 (See Fig. 15).
• Replace clevis pin and hairpin clip on inside of wheel
and remove blocks,
• 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.
ADJUST WHEELS FOR CULTIVATING (See
Figs. 16 and 17)
• Place blocks under right hand side of tiller and remove
hairpin clip and clevis pin from right hand wheel,
• Move wheel outward approximately 1 inch (2.5 cm)
until hole in inner wheel hub lines up with inner hole in
axle.

dling tines.
To maintain the superb tilling performance of this
machine the tines should be checked for sharpness,
wear, and bendlng, 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.
New tines should be assembled as shown in Fig, 28.
Sharpened tine edges will rotate rearward from above.

SERVICE AND ADJUSTMENTS
ENGINE
TO ADJUST THROTTLE CONTROL CABLE
(See Fig. 29)
• Loosen cable clamp screw to allow cable to move.
• Move throttle control lever on upper handle to “FAST"
position.
• Pull throttle cable out until engine bellcrank is back as
far as it will go.
• Hold cable in this position and tighten clamp screw
securely.
TO ADJUST CARBURETOR (See Fig. 30)
The carburetor has a high speed jet and has been preset at
the factory and adjustment should not be necessary. How
ever, minor adjustments may be required to compensate
for differences in fuel, temperature, altitude or load, If the
carburetor does need adjustment, proceed as follows.
In general, turning the idle needle valve in (clockwise)
decreases the supply of fuel to the engine giving a leaner
fuel/air mixture. Turning the needle valve out (counter
clockwise) increases the supply of fuel to the engine giving
a richer fuel/air mixture.
IMPORTANT: DAMAGE TO THE NEEDLES AND THE
SEATS IN CARBURETOR MAY RESULT IF SCREWS
ARE TURNED IN TOO TIGHT.
PRELIMINARY SETTING
• Air cleaner assembly must be assembled to the carbu
retor when making carburetor adjustments,
• Be sure the throttle control cable is adjusted property
(see above).
• With engine off, turn idle needle valve in (clockwise)
closing it finger tight and then turn valve out (counter
clockwise) 1-1/2 turns.
FINAL SETTING
• Start engine and allow to warm for five minutes. Make
final adjustments with engine running at idle and drive
control bar in "DISENGAGED" position.
• With throttle control lever in "SLOW" position, turn idle
needle valve in (clockwise) until engine begins to die
then turn out (counterclockwise) until engine runs
rough. Turn valve to a point midway between those two
positions.
IDLE RPM ADJUSTMENT
• To adjust idle RPM, rotate throttle linkage counter
clockwise and hold against stop while adjusting idle
speed adjusting screw to obtain 1750 RPM, Release
throttle linkage.
ACCELERATION TEST
• Move throttle control lever from “SLOW” to "FAST"
position. If engine hesitates or dies, turn needle valve
out (counterclockwise) 1/8 turn. Repeat test and
continue to adjust, If necessary, until engine acceler
ates smoothly.
High speed stop is factory adjusted. Do not adjust or
damage may result.
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. IFYOUTHINKTHEENGINE-GOVERNED
HIGH SPEED NEEDS ADJUSTING, CONTACT YOUR
NEAREST SEARS SERVICE CENTER, WHICH HAS
PROPER EQUIPMENT AND EXPERIENCETO MAKE ANY
NECESSARY ADJUSTMENTS,

STORAGE
Immediately prepareyour tiller for storage 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
• Clean entire tiller (See "CLEANING” in the Customer
Responsibilities section of this manual),
• Inspect and replace belts, if necessary (See belt re
placement instructions in the Service and Adjustments
section of this manual).
• Lubricate as shown in the Customer Responsibilities
, section of this manual
• Be sure that all nuts, bolts and screws are securely
fastened. Inspect moving parts for damage, breakage
and wear. Replace if necessary.
• Touch up all rusted or chipped paint surfaces; sand
lightly before painting,
ENGINE
ENGINE OIL
Drain oil (with engine warm) and replace with clean oil,
(See “ENGINE" in the Customer Responsibilities section of
this manual).
CYLINDERS
Remove spark plug.
Pour 1 ounce (29 ml) of oil through spark plug hole into
cylinder.
Pull starter handle slowly several times to distribute oil.
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 for m and
will cause your unit to rust.
IMPORTANT: NEVER COVER TILLER WHILE ENGINE
AND EXHAUST AREAS ARE STILL WARM.
FUEL SYSTEM
IMPORTANT: IT IS IMPORTANT TO PREVENT QUM
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 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.
• Drain the fuel tank.
• 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 stor
age. 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 car buretor if using fuel stabilizer.
