Disconnect spark plug wire. Drain CAUTION:from Before gasoline fuellifting tank.or transporting, 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 oilwith gasoline. Purchase fuel in quantities that can be used within 30 days to assure fue! freshness. I AROUND THE YARD Release the depth stake pin. Move the depth stake down tothetop 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. A • 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 CAUTION: Fill to within 112 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. 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. 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. SeeStorage Instructions for additional information. Never use engine or carburetor cleaner products in the fuel tank or penTtanent damage may occur. 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. • Be sure tiller is level and the area around oil fill is clean. • Check oil level before each use. Add oil if needed. Fill to full line on dipstick. • To read proper level, tighten engine oil cap each time. 9 ..... OPERATION TO START ENGINE I _[]L (See Fig. 13) TILLING "DISENGAGED" position when startCAUTION: ing engine. Keep drive control bar in HINTS handling your tiller, start actual field use with throttle in stow position (mid-way CAUTION: Until you accustomed to between "FAST" andare "IDLE"). 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. • To start a cold engine, push primer five (5) times before trying to start. Use a firm push. This step is not usually necessary when starting an engine which has already run for a few minutes. Tilling is digging into, turning over, and breaking up packed soil before planting. Loose, unpacked soilhelps root growth. Best tilling depth is 4" to 6" (10-15 cm). 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. Soil conditions are important for proper tilling.Tines will not readily penetrate dry,hard soilwhich 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. 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. 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. • 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. • Allow engine to warm up for a few minutes before engaging tines. NOTE: In cooler weather it may be necessary to repeat priming steps. In warmer weather over priming may cause flooding and engine will not start. If you do flood engine, wait a few minutes before attempting to start and do not repeat priming steps. )?(q RECOIL STARTER HANDLE PRIMER I P;/:< FIG. 13 ,'/; 5 ..,, /, ,/ /, ,..,/? // FIG. 14 10 OPERATION TINE SHEAR PINS ADJUST WHEELS Figs. 16 and 17) The tine assemblies on your tiller are secured to the tine shaft with shear pins (See 'q-INE REPLACEMEN'I "_in the Service and Adjustments 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 transmission. • • • If shear pin(s) break, replace only with those shown in the Repair Parts section of this manual. FOR CULTIVATING (See 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 (2.5 cm) until hole in inner wheet 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. CULTIVATING NOTE: In extremely rough conditions and while cultivating, the wheels should be moved outward on the axle for increased stability. Cultivating is destroying the weeds between rows to provent them from robbingnourishment 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).
