• Release forward tine control to stop forward movement.
• Release reverse tine control to stop reverse tine move
ment.
ENGINE
• Move throttle control to “STOP” position.
• Never use choke to stop engine.
FORWARD TINE CONTROL
TILLING
The speed and depth of tilling is regulated by the position of
the depth stake and wheel height.
The depth stake should always be below the wheels for
digging. It serves as a brake to slow the tiller’s forward
motion to enable the tines to penetrate the ground. Also, the
more the depth stake is lowered into the ground the deeper
the tines will dig.
DEPTH STAKE (See Fig. 6)
Adjust depth stake by removing the hairpin dip and clevis
pin. Change depth stake to desired position. Replace the
clevis pin and hairpin clip,
® For normal tilling, set depth stake at the second or third
hole from the top.
WHEELS (See Fig. 6)

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.
FILL ENGINE WITH OIL (See Fig. 7)
• With engine level, remove engine oil filler plug.
• Fill engine with oil to point of overflowing. For approxi
mate capacity see “PRODUCT SPECIFICATIONS” on
page 3 of this manual.
• Tilt tiller back on its wheels and then re-level.
• With engine level, refill to point of overflowing if neces
sary. Replace oil filler plug.
• For cold weather operation you should change oil for
easier starting (See “OIL VISCOSITY CHART” in the
Customer Responsibilities section of this manual).
• Tochange engine oil, see the Customer Responsibilities
section of this manual.
ADD GASOLINE
• Fill fuel tank. Use fresh, clean, regular unleaded
gasoline. (Use of leaded gasoline will 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 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 the 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" (1.3 cm) 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.
Do not overfill. Wipe off any spilled oil
or fuel. Do not store, spill or use gaso

TO START ENGINE (See Fig. 8)
CAUTION; Keep tine control in “OFF’
A
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.
• Make sure spark plug wire is properly connected.
• Place throttle control in “FAST” position.
• Move choke control to full “CHOKE” position. 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).
• Pull recoil starter handle quickly. Do not let starter
handle snap back against starter. Repeat if necessary.
• If engine fires but does not start, move choke control to
half choke position. Pull recoil starter handle until engine
starts.
• When engine starts, slowly move choke control to “RUN”
position as engine warms up.
NOTE: A warm engine requires less choking to start.
• 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 (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 Adjustments section of
this manual.

OPERATION
BREAKING IN YOUR TILLER
Break-in your belts, pulleys and tine control before you
actually begin tilling.
® Start engine, tip tines off ground by pressing handles
down and engage tine control to start tine rotation. Allow
tines to rotate for five minutes.
• Check tine operation and adjust if necessary. See
“TINE OPERATION CHECK” in the Service and Adjust
ments section of this manual.
TILLING HINTS
CAUTION: Until you are accustomed to
handling your tiller, start actual field use
A
To help tiller move forward, lift up the handles slightly (thus
lifting depth stake out of ground). To slow down the tiller,
press down on handles.
If you are straining ortiller is shaking, the wheels and depth
stake are not set properly in the soil being tilled. The proper
setting of the wheels and depth stake is
and depends upon the soil condition. (The harder or wetter
the ground, the slower the engine and tine speed needed.
Under these poor conditions, at fast speed the tiller will run
and jump over the ground).
A properly adjusted tiller will dig with little effort from the
operator,
• Tilling is digging into, turning over, and breaking up
packed soil before planting. Loose, unpacked soil helps
root growth. Best tilling depth is 4" to 6" (10-15 cm). 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
season to further condition the soil.
• Soil conditions are important for propertilling. Tines will
not readily penetrate dry, hard soil which may contribute
to excessive bounce and difficult handling of your tiller.
Hard soil should be moistened before tilling; however,
extremely wet soil will “ball-up” or clump during tilling.
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.
with throttle in slow position (mid-way
between “FAST” and “IDLE”).
through trial and error
the end of the growing
You will find tilling much easier if you leave a row untilled
between passes. Then go back between tilled rows.
(See Fig. 9) There are two reasons for doing this. First,
wide turns are much easier to negotiate than aboutfaces. Second, the tiller won’t be pulling itself, and you,
toward the row next to it.
Set depth stake and wheel height for shallow tilling when
working extremely hard soil or sod. Then work across
the first cuts at normal depth.
CULTIVATING
Cultivating is destroying the weeds 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),
• You will probably not need to use the depth stake.
Begin by tipping the depth stake forward until it is held
by the stake spring.
• Cultivate up and down the rov</s 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. 10).

SERVICE AND ADJUSTMENTS
ENGINE
TO ADJUST CARBURETOR
The carburetor has a high speed fixed jet and has been
preset at the factory and adjustment should not be neces
sary. However, minor adjustments may be required to
compensate for differences in fuel, temperature, altitude or
load. If the carburetor does need adjustment, see engine
manual.
High speed stop is factory adjusted,
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. IF YOU THINK THE ENGINE-GOVERNED
HIGH SPEED NEEDS ADJUSTING, CONTACT YOUR
NEAREST AUTHORIZED SERVICE CENTER/
DEPARTMENT, WHICH HAS THE PROPER EQUIPMENT
AND EXPERIENCE TO MAKE ANY NECESSARY
ADJUSTMENTS.
Do not adjust or

STORAGE
Immediately prepare your 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
A
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).
CYLiNDER(S)
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.
Coveryourunitwith 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 ENGINE
AND EXHAUST AREAS ARE STILL WARM.
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,
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.
miE: Fuel stabilizer is an acceptable alternative in
minimizing the formation ofiuel 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 carburetor if using fuel stabilizer.
