Safe Operation Practices for Walk-Behind Powered Rotary Tillers
A
TRAINING
• Read the Owner’s Manual carefully. Be thoroughly
familiar with the controls and the proper use of the
equipment. Know how to stop the unit and disengage
the controls quickly.
® Never allow children to operate the equipment. Never
allow adults to operate the equipment without proper
instruction.
• Keep the area of operation clear of all persons, particu
larly small children, and pets.
PREPARATION
® Thoroughly inspect the area where the equipment is to
be used and remove all foreign objects.
• Disengage all clutches and shift into neutral before
starting the engine (motor).
• Do not operate the equipment without wearing ad
equate outer garments. Wear footwear that will im
prove footing on slippery surfaces.
• Handle fuel with care; it is highly flammable.
• Use an approved fuel container.
• Never add fuel to a running engine or hot engine.
• Fill fuel tank outdoors with extreme care. Never fill fuel
tank indoors.
• Replace gasoline cap securely and clean up spilled
fuel before restarting.
• Use extension cords and receptacles as specified by
the manufacturer for all units with electric drive motors
or electric starting motors.
• Never attempt to make any adjustments while the
engine (motor) is running (except where specifically
recommended by manufacturer).
OPERATION
Do not put hands or feet near or under rotating parts.
Exercise extreme caution when operating on or cross
ing 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 in
spect the tiller for any damage, and repair the damage
before restarting and operating the tiller.
Exercise caution to avoid slipping or falling.
If the unit should start to vibrate abnormally, stop the
engine (motor) and check immediately for the cause.
Vibration is generally a warning of trouble.
Stop the engine (motor) when leaving the operating
position.
Take all possible precautions when leaving the ma
chine unattended. Disengage the tines, shift into
neutral, and stop the engine.
Before cleaning, repairing, or inspecting, shut off the
engine and make certain all moving parts have stopped.
Disconnect the spark plug wire, and keep the wire
away from the plug to prevent accidental starting.
Disconnect the cord on electric motors.
Do not run the engine indoors; exhaust fumes are
dangerous.
Never operate the tiller without proper guards, plates,
or other safety protective devices in place.
Keep children and pets away.
Do not overload the machine capacity by attempting to
till too deep at too fast a rate.
Never operate the machine at high speeds on slippery
surfaces. Look behind and use care when backing.
Never allow bystanders near the unit.
Use only attachments and accessories approved by
the manufacturer of the tiller (such as wheel weights,
counterweights, cabs, and the like).
Never operate the tiller without good visibility or light.
Be careful when tilling in hard ground. The tines may
catch in the ground and propel the tiller forward. If this
occurs, let go of the handlebars and do not restrain the
machine.
MAINTENANCE AND STORAGE
• Keep machine, attachments, and accessories in safe
working condition.
• Check shear pins, engine mounting bolts, and other
bolts at frequent intervals tor proper tightness to be
sure the equipment is in safe working condition.
• Never store the machine with fuel in the fuel tank inside
a building where ignition sources are present, such as
hot water and space heaters, clothes dryers, and the
like. Allow the engine to cool before storing in any
enclosure.
• Always refer to the operator’s guide instructions tor
important details it the tiller is to be stored for an
extended period.

HOW TO USE YOUR TILLER
Know how to operate all controls before adding fuel and oil
or attempting to start engine.
STOPPING (See Fig. 5)
TINES
• Release forward tine co n t r o l to stop forward move
ment.
• Release reverse tine control to stop reverse move
ment.
ENGINE
• Move throttle control to “STOP” position.
• Never use choke to stop engine.
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 clip 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 orthird
hole from the top.
WHEELS (See Fig. 6)
Adjust wheels by removing the hairpin clip and clevis pin.
Change wheel position. Replace the hairpin clip and clevis
pin.

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 tempera
tures (below 32'T), the carburetorfuel mixture may need to
be adjusted for best engine performance. See “TO AD

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 through trial and
error and depends upon the soil condition. (The harder or
wetter the ground, the slower the engine and tine speed
needed. Underthesepoorconditions, atfastspeedthe tiller
will run and jump over the ground),

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 T'-3".
• 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 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. 10).

ACCELERATION TEST
• Move throttle control lever from “SLOW” to “FAST”
position, if engine hesitates or dies, turn idle 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. 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.
FIG. 22
ENGINE
TO ADJUST CARBURETOR (See Fig. 23)
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, 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.
• 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 tine
control lever in “OFF” position.

and wear. Replace if necessary.
• Touch up all rusted or chipped paint surfaces; sand
lightly before painting.
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, 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 carburetor if using fuel stabilizer.
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 form and
will cause your unit to rust.
IMPORTANT: NEVER COVER TILLER WHILE ENGINE
AND EXHAUST AREAS ARE STILL WARM.
