• 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 eiectric 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 for 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 for

important details if the tiller is to be stored for an

extended period.

OPERATION

The operation of any tiller can result in foreign objects thrown into the eyes, which can

, result in severe eye damage. Always wear safety glasses or eye shields before starting

your tiller and while tilling. We recommend a wide vision safety mask for over the
spectacles or standard safety glasses.

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 control 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.

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 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 or third
hole fro.m 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.

• For normal tilling, set wheels at the second or third hole

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).

• To change engine oil, see the Customer Responsibili

ties 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 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

A

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
line near an open flame.

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” positio.n 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 tempera
tures (below 32'"F), the carburetorfue! mixture may need to
be adjusted for best engine performance. See “TO AD
JUST CARBURETOR” in the Service and Adjustments
section of this manual.

NOTE: If engine does not start, see troubleshooting points.

position when starting engine.

OPERATION

You will find tilling much easier if you leave a row
untilled between passes. Then go back over the entire
area at right angles (See Fig. 9). There are two reasons
for doing this. First, wide turns are much easier to
negotiate than about-faces. Second, the tillerwon’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.

nTMTnTT wTlT

HimHJTEni

BREAKING IN YOUR TILLER

Break-in your belt(s), pulleys and tine control before you
actually begin tilling.

• Start engine, tip tines off ground by pressing handies
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 Ad

justments section of this manual.

TILLING HINTS

CAUTION: Until you are accustomed to
handling your tiller, start actual field ’

A

To help tiller move forv/ard, 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 or tiller 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. 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 is4"-6". A tiller will

also clear the soil of unwanted vegetation. The decom

position of this vegetable matter enriches the soil.

Depending on the dimate (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 contrib

ute to excessive bounce and difficult handling of your
tiller. Hard soil should be moistened before tilling;

however, extremely wet soil will ‘'ball-up” or dump
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.

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"-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).

SERVICE AND ADJUSTMENTS

TO REMOVE BELT GUARD (See Fig. 22)

• . Remove two (2) cap nuts and washers from side of belt
guard.

• Loosen (do not remove) tine shield nut on underside of
tine shield.

• " Pull belt guard out and away from unit.’

• Replace belt guard by reversing above procedure. Be
sure slot in bottom of belt guard is under head of tine
shield bolt and all nuts are tightened securely.

• With throttle control 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 counterclock

wise and hold against stop while adjusting idle speed

adjusting screw to obtain 1750 RPM. Release throttle
linkage.

ACCELERATION TEST

• Move throvhe 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,

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 fuei/air mixture.

IMPORTANT: DAMAGE TO THE NEEDLES AND THE

SEATS IN CARBURETOR MAY RESULT IFSCREWS 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 (dockvi/ise)

dosing 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.

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

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
ccintainer. 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.
