SAFETY RULES

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.

• Fornormal tilling, set wheels at the second orthird hole

from the top.
