SAFETY RULES

Safe Operation Practices for Walk-BehindPowered 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.

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 ensure 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

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 SF-SJ.

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 PLUG

OIL LEVEL

MAXIMUM UPPER LEVEL

MINIMUM UPPER LEVEL

Fig. 12

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: WHENOPERATINGINTEMPERATURESBELOW 32°F(0°C), USE FRESH, CLEAN WINTER GRADE GASOLINE TO HELP ENSURE GOOD COLD WEATHER STARTING.

CAUTION:Alcoholblendedfuels(calledgasohol 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 tine control in “OFF” position when starting engine.

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

2.Open the fuel valve.

3.Turn the ENGINE SWITCH to the position “ I ” (ON).

4.Set the speed control lever 1/3 of the way towards the high speed position.

5.Close the choke lever.

NOTE: If the engine is cold or the ambient temperature is low, close the choke lever fully.

NOTE: If the engine is warm or the ambient temperature is high, open the choke leverhalf-way,or keep it fully open.

6.Pull the starter handle slowly until resistance is felt. This is the “compression” point. Return the handle to its original position and pull swiftly. Do not pull out the rope all the way. After starting the engine, allow the starter handle to return to its original position while still holding the handle.

7.After starting the engine, gradually open choke by turning the choke lever and finally keep it fully opened. Do not fully open the choke lever immediately when the engine is cold or the ambient temperature is low, because the engine may stop.

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

OPERATION

TILLING HINTS (See Fig. 14)

CAUTION: Until you are accustomed to handling your tiller, start actual field use with throttle in slow position (mid-waybetween “FAST” and “IDLE”).

Tilling is digging into, turning over, and breaking up packed soil before planting. Loose, unpacked soil helps root growth. Best tilling depth is 4" to 6" (10-15cm). A tiller will also clear the soil of unwanted vegetation. The decomposition of this vegetable matter enriches the soil. Depending on the climate (rainfall and wind), it may be advisable to till the soil at the end of the growing season to further condition the soil.

You will find tilling much easier if you leave a row untilled between passes. Then go back between tilled rows. (See Fig. 14) There are two reasons for doing this. First, wide turns are much easier to negotiate than about-faces.Second, the tiller won’t be pulling itself, and you, toward the row next to it.

Soil conditions are important for proper tilling. Tines will not readily penetrate dry, hard soil which may contribute to excessive bounce and difficult handling of your tiller. Hard soil should be moistened before tilling; however, extremely wet soil will “ball-up”or clump 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.

Do not lean on handle. This takes weight off the wheels and reduces traction. To get through a really tough section of sod or hard ground, apply upward pressure on handle or lower the depth stake.

CULTIVATING

Cultivating is destroying the weeds between rows to prevent 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" to 3" (2.5-7.5cm). Lower the outer side shields to protect small plants from being buried.

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. 15).

Do not lean on handle, this takes weight off the wheels, reduces traction, and may cause the tiller to skip over the ground.

Always lower the drag stakewhenusing theforward rotating tine drive.

Fig. 15

ADJUST WHEELS FOR CULTIVATING

(See Figs. 16 and 17)

Place blocks under right hand side of tiller and remove hairpin clip and clevis pin from right hand wheel.

Move wheel outward approximately 1 inch until hole in inner wheel hub lines up with inner hole in axle.

Replace clevis pin and hairpin clip on inside of wheel and remove blocks.

Repeat preceding steps on left hand side.

NOTE: In extremely rough conditions and while cultivating, the wheels should be moved outward on the axle for increased stability.
