• Keep the area of operation clear of all persons, par tic u lar ly 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 (mo tor).

• Do not operate the equipment with out wearing ad e quate outer gar ments. 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 rec om mend ed by manufacturer).

OPERATION

• Do not put hands or feet near or under rotating parts.

• Exercise extreme caution when op er at ing on or cross ing gravel drives, walks, or roads. Stay alert for hidden hazards or traffic. Do not carry pas sen gers.

• 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 op er at ing the tiller.

• Exercise caution to avoid slipping or falling.

• If the unit should start to vibrate ab nor mal ly, stop the engine (motor) and check immediately for the cause. Vi bra tion is generally a warning of trouble.

• Stop the engine (motor) when leaving the operating position.

• Take all possible precautions when leav ing 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.

• 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 work ing condition.

• Check shear pins, engine mounting bolts, and other bolts at frequent intervals for proper tightness to ensure the equip ment 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 im por tant details if the tiller is to be stored for an extended period.

MEETS ANSI SAFETY REQUIREMENTS

Our tillers conform to the safety standards of the American National Standards Institute.

DEPTH STAKE - Controls forward speed and the depth at which the tiller will dig.

FORWARD TINE CONTROL - Engages tines in forward direction.

RECOIL STARTER HANDLE - Used to start the engine. direction.

THROTTLE CONTROL - Controls engine speed. PRIMER - pumps additional fuel from the carburetor to the

cylinder for use when starting a cold engine.

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 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. 6)

TINES

1. Release tine control to stop move ment.

ENGINE

2. Move throttle control to "STOP" position.

TINE CONTROL “OFF” (UP) PO SI TION

TINE CONTROL “ON” (DOWN) PO SI TION

TILLING

The speed and depth of tilling is regulated by the position of the depth stake.

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. 7)

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 from the top.
