Always wear safety glasses or eye shields before starting your tiller and while tilling. We recommend a wide vision safety mask for over spectacles or standard safety glasses. HOW TO USE YOUR TILLER TILLING Know how to operate all controls before adding fuel and oil or attempting to start engine. 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. STOPPING (See Fig. 5) TINES • Release forward tine control to stop forward movement. • Release reverse tine control to stop reverse movement. 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. ENGINE • Move throttle control to “STOP” position. • Never use choke to stop engine. WHEELS (See Fig. 6) Adjust wheels by removing the hairpin clip and clevis pin. Change wheel position. Replace the hairpin clip and clevis pin. • For normal tilling, set wheels at the second or third hole from the top.

REVERSE • With forward tine control “OFF” (up) position, pull back and hold reverse tine control. 7 OPERATION TO TRANSPORT 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. Wipe off any spilled oil or fuel. Do not store, spill or use gasoline near an open flame. CAUTION: Before lifting or transporting, allow tiller engine and muffler to cool. Disconnect spark plug wire. Drain gasoline from fuel tank. AROUND THE YARD • Tip depth stake forward until it is held by the stake spring. • Push tiller handles down, raising tines off the ground. • Push or pull tiller to desired location. IMPORTANT: WHEN OPERATING IN TEMPERATURES BELOW 32°F(0°C), USE FRESH, CLEAN WINTER GRADE GASOLINE TO HELP INSURE GOOD COLD WEATHER STARTING. AROUND TOWN • Disconnect spark plug wire. • Drain fuel tank. • Transport in upright position to prevent oil leakage. 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. See Storage Instructions for additional information. Never use engine or carburetor cleaner products in the fuel tank or permanent damage may occur. BEFORE 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. FILL ENGINE WITH OIL (See Fig. 7) • • • • • • With engine level, remove engine oil filler plug. Fill engine with oil to point of overflowing. For approximate capacity see “PRODUCT SPECIFICATIONS” on page 3 of this manual. Tilt tiller back on its wheels and then re-level. With engine level, refill to point of overflowing if necessary. Replace oil filler plug. For cold weather operation you should change oil for easier starting (See “OIL VISCOSITY CHART” in the Maintenance section of this manual). To change engine oil, see the Maintenance section of this manual. TO START ENGINE (See Fig. 8) CAUTION: Keep drive control bar in “DISENGAGED” 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. • Move shift lever indicator to “N” (neutral) position. • Place throttle control in “FAST” position. • Move choke control to 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. • 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. OIL LEVEL eng t_4 _ar ine OIL FILLER PLUG Fig. 7 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. 8 OPERATION 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. • SPARK PLUG • THROTTLE CONTROL CHOKE CONTROL • RECOIL STARTER HANDLE eng ine _art _71 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 between tilled rows. (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. FIG. 8 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. 3 4 5 TILLING HINTS 2 6 1 7 Fig. 9 CAUTION: Until you are accustomed to handling your tiller, start actual field use with throttle in slow position. 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"-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). 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"-6". 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.

Check your engine oil level more frequently to avoid possible engine damage from running low on oil. Change the oil after every 25 hours of operation or at least once a year if the tiller is not used for 25 hours in one year. Check the crankcase oil level before starting the engine and after each five (5) hours of continuous use. Add SAE 30 motor oil or equivalent. Tighten oil filler plug securely each time you check the oil level. AIR CLEANER CARTRIDGE COVER AIR CLEANER SCREW TO CHANGE ENGINE OIL (See Figs. 11 and 12) Determine temperature range expected before oil change. All oil must meet API service classification SG-SL. • Be sure tiller is on level surface. • Oil will drain more freely when warm. • Catch oil in a suitable container. • Remove drain plug. • Tip tiller forward to drain oil. • After oil has drained completely, replace oil drain plug and tighten securely. • Remove oil filler plug. Be careful not to allow dirt to enter the engine. • Refill engine with oil. See “CHECK ENGINE OIL LEVEL” in the Operation section of this manual.

ENGINE OIL Drain oil (with engine warm) and replace with clean oil. (See “ENGINE” in the Maintenance section of this manual). WARNING: Never store the tiller with gasoline in the tank inside a building where fumes may reach an open flame or spark. Allow the engine to cool before storing in any enclosure. CYLINDER(S) • • TILLER • • • • • • Clean entire tiller (See “CLEANING” in the Maintenance section of this manual). Inspect and replace belts, if necessary (See belt replacement instructions in the Service and Adjustments section of this manual). Lubricate as shown in the Maintenance section of this manual. Be sure that all nuts, bolts and screws are securely fastened. Inspect moving parts for damage, breakage and wear. Replace if necessary. Touch up all rusted or chipped paint surfaces; sand lightly before painting. • 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 • • • • ENGINE 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. 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.
