AROUND TOWN TINE OPERATION • Squeeze tine control to handle. TILLING The speed and depth of tilling is regulated by the position of the depth stake and wheel height. • Disconnect spark plug wire. • Drain fuel tank. The depth stake should always be below the wheels for digging. It serves as a brake to slow the titler'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. • Transport in upright oil leakage. BEFORE STARTING IMPORTANT: Be very dirt to enter the engine adding oil or fuel. Use and store in approved, containers. Use clean DEPTH FILL ENGINE STAKE Adjust depth stake by removing the hairpin clip and clevis pin. Change depth stake to desired position.

With engine level, remove engine oil filler plug. • Fill engine with oil to point of overflowing. For approximate capacity see =PRODUCT SPECIFICATIONS" on page 4 of this manual. 8 • Tilt tiller back on its wheels and then relevel. • 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. Oil Level, ADD GASOLINE • Fill fuel tank. Use fresh, clean, regular unleaded gasoline. (Use of leaded gasoline will increase carbon and lead oxide deposits and reduce valve life.) IMPORTANT: When operating in Temperatures below 32°F (0°C), use fresh, clean, winter grade gasoline to help insure good cold weather starting. WARNING: 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. 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 TO START ENGINE _CAUTION: Keep line 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. NOTE: Awarm 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. 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. _,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. Spark Plug Choke Control Recoil, ;tarter BREAKING IN YOUR TILLER Break-in your belt(s), pulleys and tine control before you actually begin tilling. 9 • Startengine,tip tinesoff groundby pressinghandlesdown andengageline controlto start line rotation.Allowtines to rotatefor five minutes. You will find tilling much easier if you leave a row untilled between passes. Then go back be,tween tilled rows.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. • Check tine operation and adjust if necessary. See "FINE OPERATION CHECK" in the Service and Adjustments section of this manual. Set depth stake and wheel height for shallow tilling when working extremely hard soil or sod. Then work across the TILLING HINTS _CAUTION: Until you are accustomed to handling your tiller, start actual field use with throttle in slow position (mid-way between =FAST" and =IDLE"). 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. first cuts at normal depth. 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". • 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". A tiller will also clear the soil of unwanted vegetation. The decomposition of this vegetable matter enriches the soil. 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. 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 line shaft and slowing your tilling operation.

GENERAL RECOMMENDATIONS LUBRICATION The warranty on this tiller does not cover items that have been subjected to operator abuse or negligence. To receive full value from the warranty, operator must maintain tiller as instructed in this manual, CHART * TINE CONTROL Some adjustments will need to be made periodically to propedy maintain your tiller. ** ENGINE All adjustments in the Service and Adjustments section of this manual should be checked at least once each season. • Once a year you should replace the spark plug, clean or replace air filter, and check tines and belt for wear. A new spark plug and clean air filter assure proper air-fuel mixture and help your engine run better and last longer. BEFORE EACH USE • Check engine oil level. • Check fine operation. • Check for loose fasteners. * IDLER ARM LUBRICATION Keep unit well lubricated (See "LUBRICATION CHART"). • SAE 30 OR 10W30 MOTOR OIL ** REFER TO MAINTENANCE "ENGINE" SECTION. 11 Disconnect spark plug wire before performing any maintenance (except carburetor adjustment) to prevent accidental starting of engine. • Refill engine with oil. See =FILL ENGINE WITH OIL" in the Operation section of this manual. Prevent firest Keep the engine free of grass, leaves, spilled oil, or fuel. Remove fuel from tank before tipping unit for maintenance. Clean muftler area of all grass, dirt, and debris. Do not touch hot muffler or cylinder contact may cause burns. ENGINE Oil Drain Oil Filter Plug fins as AIR CLEANER LUBRICATION Use only high quality detergent oil rated with API service classification SF, SG or SH. Select the oil's SAE viscosity grade according to your expected temperature. Service air cleaner cartridge every 50 hours, more often if engine is used in very dusty conditions. • Loosen air cleaner screws, one on each side of cover. • Remove air cleaner cover. • Carefully remove air cleaner cartridge. Be careful. Do not allow dirt or debris to fall into carburetor. • Clean by tapping gently on a flat surface. NOTE: Although multi-viscosity oils (5W30, 10W-30, etc.) improve starting in cold weather, these multi-viscosity oils will result in increased oil consumption when used above 32°F (0°C). Check your engine oil level more frequently to avoid • possible engine damage from running low on oil. Change the oil after every 50 hours of operation or at least once a year if the tiller is not used for 50 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. TO CHANGE ENGINE • If very dirty or damaged, replace cartridge. • Clean and replace cover. Tighten screws securely. _.CAUTION: Petroleum solvents, such as kerosene, are not to be used to clean cartridge. They may cause deterioration of the cartridge. Do not oil cartridge. Do not use pressurized air to clean or dry cartridge. ;over Air Cleaner Screw Air Cleaner Cartndge OIL Determine temperature range expected before oil change.

TO ADJUST CARBURETOR Idle Speed Adjusting Screw The carburetor has a high speed jet and has been preset at the factory and adjustment should not be necessary. However, minor adjustments may be required to compensate for differences in fuel, temperature, altitude or load. If the carburetor does need adjustment, proceed as follows. FINAL SETI'ING • Start engine and allow to warm for five minutes. • With throttle control lever in "SLOW" position. 15 Throttle Stop Immediately prepare your tiller for storage at the end of the season or if the unit will not be used for 30 days or more. _,CAUTION: 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. 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. ENGINE 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. • Drain the fuel tank. NOTE: Fuel stabilizt_r 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 stabilizer container. Run engine at least 10 minutes after adding stabilizer to allow the stabilizer to reach the carburetor. Do not drain the gas tank and carburetor if using fuel stabilizer. ENGINE OIL Drain oil (with engine warm) and replace with clean oil. (See "ENGINE" in the Customer Responsibilities section of this manual). CYLINDER(S) • Remove spark plug. • Pour I 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 • Do not store gasoline to another. from one season • 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. • Start 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 damage may occur. • Use fresh fuel next season. 16 PROBLEM Will not start CAUSE CORRECTION 1.
