SAFETY RULES

SAFE OPERATION PRACTICES FOR WALK-BEHIND POWERED ROTARY TILLERS

TRAINING

• Read the Owner’s Manual carefully. Be thoroughly
familiar with the controls and the proper use of the
equipment. Know howto 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 ail persons, particu­tarty 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 adequate
outer garments. Wear footwear that will improve 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 alt 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 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 tillerfor any damage, and repairthe 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 machine
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.

A

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.
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
boltsatfrequentintervalsforpropertightnessto 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 coo! 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.

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

OPERATION

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 movement.

• Release reverse tine control to stop reverse movement.

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 toenabiethetinesto 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 dip.

• For normal tilling, set depth stake atthe second or third
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.

• For norma! tilling, set wheels atthe second orthird hole
from the top.

TINE OPERATION (See Fig. 5)

FORWARD

• Squeeze forward tine control to handle.

REVERSE

• With forward tine control “OFF” (up) position, pull back
and hold reverse tine control.

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

page 3 of this manual.

• Tilt tiller back on its wheels and then re-levei.

• 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, seethe Customer Responsibilities
section of this manual.

ADD GASOLINE

• Fill fuel tank. Use fresh, dean, 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.

When starting engineforthefirsttimeor if engine has run out
of fuel, it wilt 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 starterhandle with one handand grasp tiilerhandle
with other hand. Pul! 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. Puli 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: Ifatahigh altitude (3000feet)orin cold temperatures
