• Never allow children to operate the equipment. Never allow adults to op er ate the equipment without proper instruction.

• 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 ﬂ ammable.

• Use an approved fuel container.

• Never add fuel to a running engine or hot engine.

• Fill fuel tank outdoors with extreme care. Never ﬁ ll fuel tank indoors.

• Replace gasoline cap securely and clean up spilled fuel before restarting.

• Use extension cords and receptacles as speciﬁ ed 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 speciﬁ cally 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 trafﬁ c. 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.

FIG. 12

ADD GASOLINE

• Fill fuel tank to bottom of ﬁ ller neck. Do not overﬁ ll. Use fresh, clean, regular un lead ed 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 quan ti ties 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 ac ci den tal ly 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 ﬂ ame.

IMPORTANT: WHEN OPERATING IN TEMPERATURES

BELOW32°F(0°C), USE FRESH, CLEAN WINTER GRADE GAS O LINE TO HELP INSURE GOOD COLD WEATHER START ING.

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 AP PROVED, 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 ﬁ lled with SAE 30 summer weight oil.

• With engine level, clean area around oil ﬁ ller plug and remove plug.

• Engine oil should be to point of overﬂ owing when engine is level. For ap proxi mate capacity see “PROD UCT SPEC I FI CA TIONS” on page 3 of this manual. All oil must meet A.P.I. Service Classiﬁ cation SF-SJ.

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

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

CAUTION: Alcohol blended fuels (called gas o hol or using ethanol or methanol) can attract moisture which leads to sep a ra tion and for ma tion 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 stor age 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 sea son. See Storage In struc tions 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 start ing en gine.

When starting engine for the ﬁ rst 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 prop er ly connected.

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

• Place throttle control in “FAST” position.

9

OPERATION

• 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 com pres sion 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 ﬁ res but does not start, move choke control to half choke position. Pull 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: If at a high altitude (3000 feet) or in cold tem per a tures (below 32°F), the carburetor fuel mixture may need to be adjusted for best engine performance. See "TO AD JUST CARBURETOR" in the Service and Adjustments section of this manual.

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

FIG. 14

• Soil conditions are important for proper tilling. Tines will not readily penetrate dry, hard soil which may con trib ute to excessive bounce and difﬁ cult handling of your tiller. Hard soil should be mois tened 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, re move 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.

FIG. 13

TILLING HINTS

CAUTION: Until you are accustomed to handling your tiller, start actual ﬁ eld use with throttle in slow position (mid-way between “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" (10-15 cm). A tiller will also clear the soil of unwanted vege ta tion. The de com po si tion of this vegetable mat ter enriches the soil. Depending on the climate (rain fall and wind), it may be advisable to till the soil at the end of the growing season to further condition the soil.

• You will ﬁ nd 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. Sec ond, the tiller won’t be pulling itself, and you, toward the row next to it.

CULTIVATING

Cultivating is destroying the weeds between rows to pre vent 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" (2.5-7.5 cm). 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).

FIG. 15

TINE SHEAR PINS

The tine assemblies on your tiller are secured to the tine shaft with shear pins (See “TINE REPLACEMENT” in the Service and Ad just ments section of this manual).

If the tiller is unusually overloaded or jammed, the shear pins are designed to break before internal damage occurs to the trans mis sion.

• If shear pin(s) break, replace only with those shown in the Repair Parts section of this manual.

NOTE: Although multi-viscosity oils (5W-30, 10W-30, etc.)

improve starting in cold weather, these multi-viscosity oils will result in increased oil consumption when used above 40°F (4°C). Check your engine oil level more frequently to avoid possible engine damage from running low on oil.

Change the oil after every 25 hours of operation or at least once a year if the tiller is not used for 25 hours in one year.

Check the crankcase oil level before starting the engine and after each ﬁ ve (5) hours of continuous use. Add SAE 30 motor oil or equivalent. Tighten oil ﬁ ller plug securely each time you check the oil level.

TO CHANGE ENGINE OIL (See Figs. 16 and 17)

Determine temperature range expected before oil change. All oil must meet API service classiﬁ cation SF-SJ.

• Be sure tiller is on level surface.

• Oil will drain more freely when warm.

• Use a funnel to prevent oil spill on tiller, and catch oil in a suitable con tain er.

• Remove drain plug. For easier removal of plug use

GROUND DRIVE BELT ADJUSTMENT (See Fig. 23)

For proper belt tension, the extension spring should have about 5/8 inch stretch when drive control bar is in “EN GAGED” position. This tension can be attained as follows:

• Loosen cable clip screw securing the drive control cable.

• Slide cable forward for less tension and rearward for more tension until about 5/8 inch stretch is obtained while the drive control bar is engaged.

• Tighten cable clip screw securely.

TINE REPLACEMENT (See Figs. 24, 25, and 26)

CAUTION: Tines are sharp. Wear gloves or other protection when han dling tines.

A badly worn tine causes your tiller to work harder and dig more shallow. Most important, worn tines cannot chop and shred organic matter as effectively nor bury it as deeply as good tines. A tine this worn needs to be replaced.

NEW TINE

FIG. 24

WORN TINE

• To maintain the superb tilling performance of this ma chine the tines should be checked for sharpness, wear, and bending, particularly the tines which are next to the transmission. If the gap between the tines ex ceeds 3-1/2 inches (9 cm), they should be replaced or straight ened as necessary.

• New tines should be assembled as shown in Fig.

26. Sharp ened tine edges will rotate rearward from above.

The throttle control has been preset at the factory and ad just ment should not be necessary. If adjustment is necessary, proceed as follows:

• With engine not running, move remote throttle control lever to “FAST” position.

• If throttle lever on engine touches high speed stop, no further adjustment is necessary. If throttle lever does not touch high speed stop, continue with adjustment procedure.

• Loosen cable clamp screw.

• Move throttle lever up until it touches high speed stop, and hold in this position.

• Tighten cable clamp screw securely.

TO AD JUST CARBURETOR

The carburetor has been preset at the factory and ad just ment should not be necessary. However, engine per for mance can be affected by dif fer enc es in fuel, tem per a ture, al ti tude or load. If the carburetor does need ad just ment, contact your nearest authorized service center/de part ment

IMPORTANT: NEVER TAMPER WITH THE ENGINE GOVERNOR, WHICH IS FACTORY SET FOR PROPER ENGINE SPEED. OVER SPEED ING THE ENGINE ABOVE THE FACTORY HIGH SPEED SETTING CAN BE DANGEROUS. IF YOU THINK THE ENGINE-GOVERNED HIGH SPEED NEEDS ADJUSTING, CONTACT YOUR NEAREST AUTHORIZED SERVICE CENTER/ DEPARTMENT, WHICH HAS THE PROPER EQUIP MENT AND EXPERIENCE TO MAKE ANY NEC ES SARY ADJUSTMENTS.

STORAGE

Immediately prepare your tiller for storage at the end of the season or if the unit will not be used for 30 days or more.

WARNING: Never store the tiller with gasoline in the tank inside a build ing where fumes may reach an open ﬂ ame or spark. Allow the engine to cool before storing in any en clo sure.

TILLER

• Clean entire tiller (See “CLEANING” in the Maintenance section of this manual).

• Inspect and replace belts, if necessary (See belt re place ment instructions in the Service and Ad just ments section of this manual).

• Lubricate as shown in the Maintenance section of this manual.

• Be sure that all nuts, bolts and screws are securely fastened. Inspect moving parts for damage, break age and wear. Replace if necessary.

• Touch up all rusted or chipped paint surfaces; sand lightly before painting.

ENGINE

FUEL SYSTEM

IMPORTANT: IT IS IMPORTANT TO PREVENT GUM DEPOSITS

FROM FORMING IN ES SEN TIAL FUEL SYS TEM PARTS SUCH AS THE CAR BU RE TOR, FUEL FILTER, FUEL HOSE, OR TANK DURING STOR AGE. ALSO, EXPERIENCE INDICATES THAT AL CO HOL BLENDED FUELS (CALLED GASOHOL OR USING ETHA NOL OR METHA NOL) CAN ATTRACT MOIS TURE WHICH LEADS TO SEPA RA TION AND FORMATION OF ACIDS DUR ING STOR AGE. ACIDIC GAS CAN DAMAGE THE FUEL SYSTEM OF AN ENGINE WHILE IN STOR AGE.

• Empty the fuel tank by starting the engine and let it run until the fuel lines and carburetor are empty.

• Never use engine or carburetor cleaner products in the fuel tank or permanent.

• Use fresh fuel next season.

NOTE: Fuel stablizer is an acceptable alternative in minimizing the formation of fuel gum deposits during storage. Add stabilizer to gasoline in fuel tank or storage container. Always follow the mix ratio found on stablizer container. Run engine at least 10 minutes after adding stablizer to allow the stabilizer to reach the carburetor. Do not empty the gas tank and carburetor if using fuel stabilizer.

ENGINE OIL

Drain oil (with engine warm) and replace with clean oil. (See “ENGINE” in the Maintenance section of this man ual).

CYLINDER(S)

• Remove spark plug.

• Pour 1 ounce (29 ml) of oil through spark plug hole into cylinder.

• Pull starter handle slowly several times to distribute oil.

• Replace with new spark plug.

OTHER

• Do not store gasoline from one season to another.

• Replace your gasoline can if your can starts to rust. Rust and/or dirt in your gasoline will cause problems.

• If possible, store your unit indoors and cover it to give protection from dust and dirt.

• Cover your unit with a suitable protective cover that does not retain moisture. Do not use plastic. Plastic cannot breathe which allows condensation to form and will cause your unit to rust.

IMPORTANT: NEVER COVER TILLER WHILE EN GINE AND EX HAUST AREAS ARE STILL WARM.
