HOW TO USE YOUR TILLER
Know howto operate all controls before adding fuel and oil or attempting to start engine.
STOPPING
TINES
* Release tine control to stop movement.
ENGINE
* Move throttle control to "STOP" position.
NOTE: choke to stop engine. "Off" (UP) Position
TINE OPERATION
* Squeeze tine control to handle.
TILLING
The speed and depth of tilling is regulated by the position ofthe depth stake and wheel height.
The depth stake should always be belowthe 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.
DEPTH STAKE
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.
WHEELS
Adjust wheels by removing the hairpin clip and clevis pin. Change wheel position. Replace the hairpin clip and clevis pin.
- Fornormaltilling, setwheelsatthesecond or third hole from the top.
TO TRANSPORT
CAUTION: Before lifting or transporting, allow tiller engine and muffler to cool. Disconnect spark plug wire. Drain gasoline from fuel tank.
AROUND THE YARD
1. Tip depth stake forward until it is held by the stake spring.
2. Push tiller handles down, raising tines off the ground.
3. Push or pull tiller to desired location.
AROUND TOWN
1. Disconnect spark plug wire.
2. Drain fuel tank.
3. Transport in upright position to prevent oil leakage.
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
1. Remove hangtag from engine.
2. With engine level, remove engine oil filler plug.
3. Fill engine with oil to point of overflowing. For approximate capacity see "PRODUCT SPECIFICATIONS" on page 4 of this manual. All oil must meetA.RI. Service Classification SG-SL.
4. Tilt tiller back on its wheels and then re-level.
5. 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, seethe Maintenance section of this manual.
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.
CAUTION: Fill to within 1/2" of top of fuel tank to prevent spills and to allow for fue! 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 below 32°F(0°C), use fresh, clean winter grade gasoline to help insure good cold weather starting.
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 damagethe 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 fue! 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.
TO START ENGINE
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.
1. Make sure spark plug wire is properly connected.
2. Place throttle control in "FAST" position.
3. Movechokecontroltofull"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 pression cycle (rope will pull slightly harder at this point).
4. Pull recoil starter handle quickly. Do not let starter handle snap back against starter. Repeat if necessary.
NOTE: If engine fires but does not start, move choke control to half choke position. Pull recoil starter handle until engine starts.
5. When engine starts, slowly move choke control to "RUN" position as engine warms up.
NOTE: A warm engine requires less choking to start.
6. Move throttle control to desired running position.
7. Allowenginetowarm upforafewminutes before engaging tines.
NOTE: If at a high altitude (3000 feet) or in cold temperatures (below 32°F/0°C), 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.
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 engagetine 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
CAUTION: Until you are accustomed to handling your tiller, start actual field use with throttle in slow position. 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.
• 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 ifyou leave a row untilled between passes. Then go back between tilled rows There are two reasons for doing this. First, wide turns are much easier to negotiate than aboutfaces. 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.
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.
MAINTENANCE
1 - Change more often when operating under a heavy load or in high ambient temperatures.
2 - Service more often when operating in dirty or dusty conditions.
GENERAL RECOMMENDATIONS
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, the operator must maintain tiller as instructed in this manual.
Some adjustments will need to be made periodically to properly maintain your tiller. 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 belts for wear. Anewspark plug and clean air filter assure proper air-fuel mixture and help your engine run better and last longer.
BEFORE EACH USE
1. Check engine oil level.
2. Checktine operation.
3. Check for loose fasteners.
LUBRICATION Keep unit well lubricated (See "LUBRICATION CHART") .
CAUTION:Disconnect spark plug wire before performing any maintenance (except carburetor adjustment) to prevent accidental starting of engine.
Prevent fires! Keep the engine free of grass, leaves, spilled oil, or fuel. Remove fuel from tank before tipping unit for maintenance. Clean muffler area of all grass, dirt, and debris.
Do not touch hot muffler or cylinder fins as contact may cause burns.
ENGINE
LUBRICATION
Use only high quality detergent oil rated with API service classification SG-SL Selectthe oil's SAE viscosity grade according to your expected temperature.
NOTE: Although multi-viscosity oils (5W30, 10W-30, etc.) improve starting in cold weather, these m ulti-viscosity oils will result in increased oil consumption when used above 32°F (0°C). Checkyour engine oil level more frequentlyto 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.
Checkthe 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 OIL
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.
1. Remove drain plug.
2. Tip tiller forward to drain oil.
3. After oil has drained completely, replace oil drain plug and tighten securely.
4. Remove oil filler plug. Be careful not to allow dirt to enter the engine. 5. Refill enginewith oil. See "FILL ENGINE WITH OIL " in the Operation section of this manual.
AIR CLEANER
Service air cleaner cartridge every 50 hours, more often if engine is used in very dusty conditions.
1. Loosen air cleaner screw.
2. Remove air cleaner cover.
3. Carefully remove air cleaner cartridge. Be careful. Do not allow dirt or debris to fall into carburetor.
4. Clean bytapping gentlyon afiatsurface.
NOTE: If very dirty or damaged, replace cartridge.
5. Clean and replace cover. Tighten screw 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 airto clean or dry cartridge.
COOLING SYSTEM
Your engine is air cooled. For proper engine performance and long life keep your engine clean.
• Clean air screen frequently using a stiffbristled brush.
• Remove blower housing and clean as necessary.
• Keep cylinder fins free of dirt and chaff.
MUFFLER
Do not operate tiller without muffler. Do not tamper with exhaust system. Damaged mufflers or spark arresters could create a fire hazard. Inspect periodically and replace if necessary. If your engine is equipped with a spark arrester screen assembly, remove every 50 hours for cleaning and inspection. Replace if damaged.
SPARK PLUG
Replace spark plugs at the beginning of each tilling season or after every 50 hours of use, whichever comes first. Spark plug type and gap setting are shown in "PRODUCT SPECIFICATIONS" on page 4 of this manual.
TRANSMISSION
Your transmission is sealed and will not require lubrication unless serviced.
CLEANING
Do not clean your tiller when the engine and transmission are hot. We do not recommend using pressurized water (garden hose, etc.) to clean your unit unless the gasket area around thetransmission and the engine muffler, air filter and carburetor are covered to keep water out. Water in engine will shorten the useful life of your tiller.
• Clean engine, wheels, finish, etc. of all foreign matter.
• Keep finished surfaces and wheels free of all gasoline, oil, etc.
• Protect painted surfaces with automotive type wax.
SERVICE AND ADJUSTMENTS
CAUTION: Disconnect spark plug wire from spark plug and place wire where it cannot come into contact with plug.

TO ADJUST CARBURETOR
The carburetor has been preset at the factory and adjustment should not be necessary. However, engine performance can be affected by differences in fuel, temperature, altitude or load. Ifthe carburetor does need adjustment, contact your nearest authorized service center/department
IMPORTANT: Never tamper with the engine governor, which is factory set for proper engine speed. Overspeeding the engine above the factory high speed setting can be dangerous. If you thinkthe engine-governed high speed needs adjusting, contact your nearest sears or other qualified service center which has the proper equipment and experience to make any necessary adjustments
STORAGE
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.
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.
TILLER
1. Clean entire tiller (See "CLEANING" in the Maintenance section of this manual).
2. Inspect and replace belts, if necessary (See belt replacement instructions in the Service and Adjustments section of this manual).
3. Lubricate as shown in the Maintenance section of this manual.
4. Be sure that all nuts, bolts and screws are securely fastened. Inspect moving parts for damage, breakage and wear. Replace if necessary. 5. 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, 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.
• Emptythefuel tank by starting the engine and letting 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.
NOTE: Fuel stabilizer 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 empty the gas tank and carburetor if using fuel stabilizer.
ENGINE OIL
Drain oil (with engine warm) and replace with clean oil. (See "ENGINE" inthe Maintenance section of this manual).
CYLINDER
1. Remove spark plug.
2. Pour 1 ounce (29ml) ofoilthroughspark plug hole into cylinder.
3. Pull starter handle slowly several times to distribute oil.
4. Replace with new spark plug.
OTHER
- 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.
