OPERATION
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 ac- cidentally 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 at- tract 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
CAUTION: Keep tine control in ???OFF??? 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.
1.Make sure spark plug wire is properly connected.
2.Place throttle control in ???FAST??? position.
3.Move choke control to full ???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).
4.Pull recoil starter handle quickly. Do not let starter handle snap back against starter. Repeat if neces- sary.
NOTE: If engine fires but does not start, move choke control to half choke position. Pull recoil starter handle
until engine starts.
5.When engine starts, slowly move choke control to ???RUN??? position as engine warms up.
NOTE: A warm engine requires less choking to start.
6.Move throttle control to desired running position.
7.Allow engine to warm up for a few minutes before engaging tines.
NOTE: If at a high altitude (3000 feet) or in cold tem- peratures (below 32??F), the carburetor fuel mixture may need to be adjusted for best engine performance. See ???TO ADJUST CARBURETOR??? in the Service and Adjust- ments section of this manual.

TILLING HINTS (See Fig. 15)
CAUTION: Until you are accustomed to handling your tiller, start actual field use with throttle in slow position
???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"
???You will find tilling much easier if you leave a row un- tilled 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
???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

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. 15
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"
???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. 16).
???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.

???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.

TINE REPLACEMENT
(See Figs. 27, 28 and 29)
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.
FIG. 27
???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 exceeds
???For tines that are slightly worn, the bolted tine and hub assemblies can be switched between sides to continue tilling in the same tilling mode if tilling in a different mode is desired then the bolted tine and hub assemblies should be switched back to their original side so that the tine edge with the least wear will be used.

ENGINE
FUEL SYSTEM
IMPORTANT: IT IS IMPORTANT TO PREVENT GUM DEPOSITS
FROM FORMING IN ESSENTIAL FUEL SYSTEM PARTS SUCH
AS THE CARBURETOR, FUEL FILTER, FUEL HOSE, OR TANK
DURING STORAGE. ALSO, EXPERIENCE INDICATES THAT
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.
???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 manual).
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 ENGINE AND
EXHAUST AREAS ARE STILL WARM.
