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 section of this manual for additional information. Never use engine or carburetor cleaner products in the fuel tank or permanent damage may occur. A 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. Do not overfill. Wipe off any spilled oil or fuel. Do not store, spill or use gasoline near an open flame. TO START ENGINE (See Fig. 8) A 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. • Make sure spark plug wire is properly connected. • 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 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. Repeat if necessary. If engine fires 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. 9 OPERATION NOTE: A warm engine requires less choking to start. • Move throttle control to desired running position. • Allow engine to warm up tor a few minutes before engaging tines. NOTE: If at a high altitude (3000 feet) or in cold temperatures (below 32°F), the carburetorfuel 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 Break-in your belt(s), pulleys and tine control before you actually begin tilling. • Start engine, tip tines off ground by pressing handles down and engage tine control to start tine rotation. Allow tines to rotate for five minutes. • Check tine operation and adjust if necessary. See “TINE OPERATION CHECK” in the Service and Adjustments section of this manual. TILLING HINTS 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. Underthese 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 is4“-6". A tiller will also clearthe 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 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. • You will find tilling much easier if you leave a row untilled between passes. Then go back over the entire area at right angles (See Fig. 9). 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. • Set depth stake and wheel height for shallow tilling when working extremely hard soil or sod. Then work across the first cuts at normal depth. 1* *. ,v, « s ^ y ) ffj f+T fl i* i JET" »- -*• r \ ITT WOT gj- TfTITi fi M TFT \ - V rrtr T*i iTTiTT if! ITT t!
