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 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, particularly 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 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 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 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 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.

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 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

When you have completed your turn-around, release the drive control bar and lower handle. Place shift lever in till position and move throttle control to desired speed. To begin tilling, hold drive control bar against the handle.

TO TRANSPORT

CAUTION: Before lifting or transporting, allow tiller engine and muffler to cool. Disconnectsparkplug wire. Drain gasoline from fuel tank.

AROUND THE YARD

Release the depth stake pin. Move the depth stake down to the top hole for transporting the tiller. Place depth stake pin in hole of depth stake to lock in position. This prevents tines from scuffing the ground.

Place shift lever indicator in “F” (forward) position for transporting.

Hold the drive control bar against the handle to start tiller movement. Tines will not turn.

Move throttle control to desired speed.

AROUND TOWN

Disconnect spark plug wire.

Drain fuel tank.

Transport in upright position to prevent oil leakage.

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.

CHECK ENGINE OIL LEVEL (See Fig.12)

The engine in your unit has been shipped, from the factory, already filled with SAE 30 summer weight oil.

With engine level, clean area around oil filler plug and remove plug.

Engine oil should be to point of overflowing when engine is level. For approximate capacity see “PRODUCT SPECIFICATIONS” on page 3 of this manual. All oil must meet A.P.I. Service Classification SG-SL.

For cold weather operation you should change oil for easier starting (See oil viscosity chart in the Maintenance section of this manual).

To change engine oil, see the Maintenance section in this manual.

OIL FILLER

ADD GASOLINE

Fill fuel tank to bottom of filler neck. Do not overfill. Use fresh, clean, regular unleaded gasoline with a minimum of 87 octane. (Use of leaded gasoline will increase carbon and lead oxide deposits and reduce valve life). Do not mix oil with gasoline. Purchase fuel in quantities that can be used within 30 days to assure fuel freshness.

CAUTION: Fill to within 1/2 inch of top of fuel tank to prevent spills and to 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.

Wipe off any spilled oil or fuel. Do not store, spill or use gasoline near an open flame.

IMPORTANT: WHEN OPERATING IN TEMPERATURES BELOW32°F(0°C), USE FRESH, CLEAN WINTER GRADE GASOLINE TO HELP INSURE GOOD COLD WEATHER STARTING.

CAUTION: 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 Instructions for additional information. Never use engine or carburetor cleaner products in the fuel tank or permanent damage may occur.

TO START ENGINE (See Fig. 13)

CAUTION: Keep drive control bar in “DISENGAGED” position when starting engine.

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.

Move shift lever indicator to “N” (neutral) position.

Place throttle control in “FAST” position.

Turn fuel shut-off valve 1/4 turn to open position.

Move choke control to 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.

If engine fires but does not start, move choke control to half choke position. Pull recoil starter handle until engine starts.
