TINE OPERATION (See Fig. 5)
???Squeeze tine control to handle.
TILLING
The speed and depth of tilling is regulated by the position of the depth stake and wheel height.
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. 6)
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.
WHEELS (See Fig. 6)

ADD GASOLINE
???Fill fuel tank to bottom of ???ller neck. Do not over???ll. 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 ???ame.
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 (See Fig. 8)
CAUTION: Keep drive control bar in ???DISENGAGED??? position when start- ing engine.
When starting engine for the ???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 properly connected.
???Move shift lever indicator to ???N??? (neutral) position.
???Place throttle control in ???FAST??? position.
???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 en- gine 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. Repeat if neces- sary.
???If engine ???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 (above 3000 feet) or in cold temperatures (below 32??F), the carburetor fuel mixture may need to be adjusted for best engine performance. See ???TO ADJUST CARBURETOR??? in the Service and Adjustments section of this manual.
NOTE: If engine does not start, see troubleshooting points.

BREAKING IN YOUR TILLER
???Start engine, tip tines off ground by pressing handles down and engage tine control to start tine rotation. Allow tines to rotate for ???ve minutes.
???Check tine operation and adjust if necessary. See???TINE OPERATION CHECK??? in the Service and Adjustments section of this manual.
TILLING HINTS
CAUTION: Until you are accustomed to handling your tiller,start actual ???eld use with throttle in slow position
To help tiller move forward, lift up the handles slightly (thus lifting depth stake out of ground). To slow down the tiller, press down on handles.
If you are straining or tiller is shaking, the wheels and depth stake are not set properly in the soil being tilled.The proper setting of the wheels and depth stake is through trial and error and depends upon the soil condition. (The harder or wetter the ground, the slower the engine and tine speed needed. Under these poor conditions, at fast speed the tiller will run and jump over the ground).
A properly adjusted tiller will dig with little effort from the operator.
???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"
???Soil conditions are important for proper tilling.Tines will not readily penetrate dry, hard soil which may contribute to excessive bounce and dif???cult handling of your tiller. Hard soil should be moistened before tilling; however, extremely wet soil will
???You will ???nd tilling much easier if you leave a row un- tilled between passes. Then go back between tilled rows. (See Fig. 9) There are two reasons for doing this. First, wide turns are much easier to negotiate than
???Set depth stake and wheel height for shallow tilling when working extremely hard soil or sod. Then work across the ???rst cuts at normal depth.
FIG. 9
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 up- per layer of soil crust will help retain moisture in the soil. Best digging depth is 1" to 3"
???You will probably not need to use the depth stake. Begin by tipping the depth stake forward until it is held by the stake spring.
???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. 10).
