Resumen del manual
Never use engine or carburetor cleaner products in the fuel tank or permanent damage may occur. TO START ENGINE (See Fig. 13) CAUTION: Keep tine control in “OFF” position when starting engine. 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 erly connected. • Move shift lever indicator to “N” (neutral) position. 9 OPERATION • 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 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 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. 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 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. RE COIL STARTER HANDLE THROTTLE CON TROL CHOKE CON TROL SPARK PLUG 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”). • Soil conditions are important for proper tilling.Tines will not readily penetrate dry, hard soil which may con tribute to excessive bounce and difficult 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. 3 2 1 5 4 6 7 FIG. 14 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 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 • 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 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. Sec ond, the tiller won’t be pulling itself, and you, toward the row next to it. 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. 10 MAINTENANCE MAINTENANCE SCHEDULE REGULAR SERVICE PERIOD (3) ITEM Performed at every indicatedmonth or operating hour interval, whichever comes first.
