PREPARATION
•Thoroughly inspect the area where the equipment is to be used and remove all foreign objects.
•Disengage all clutches and shift into neutral before starting the engine (motor).
•Never operate the tiller without good visibility or light.
•Be careful when tilling in hard ground. The tines may catch in the ground and propel the tiller forward. If this occurs, let go of the handlebars and do not restrain the machine.
•Do not operate the equipment without wearing adequate outer garments. Wear footwear that will improve footing on slippery surfaces.
•Handle fuel with care; it is highly flammable.
•Use an approved fuel container.
•Never add fuel to a running engine or hot engine.
•Fill fuel tank outdoors with extreme care. Never fill fuel tank indoors.
•Replace gasoline cap securely and clean up spilled fuel before restarting.
•Use extension cords and receptacles as specified by the manufacturer for all units with electric drive motors or electric starting motors.
•Never attempt to make any adjustments while the engine (motor) is running (except where specifically recommended by manufacturer).
OPERATION
•Do not put hands or feet near or under rotating parts.
•Exercise extreme caution when operating on or crossing gravel drives, walks, or roads. Stay alert for hidden hazards or traffic. Do not carry passengers.
•After striking a foreign object, stop the engine (motor), remove the wire from the spark plug, thoroughly inspect the tiller for any damage, and repair the damage before restarting and operating the tiller.
•Exercise caution to avoid slipping or falling.
•If the unit should start to vibrate abnormally, stop the engine (motor) and check immediately for the cause. Vibration is generally a warning of trouble.
•Stop the engine (motor) when leaving the operating position.
•Take all possible precautions when leaving the machine unattended. Disengage the tines, shift into neutral, and stop the engine.
•Before cleaning, repairing, or inspecting, shut off the engine and make certain all moving parts have stopped. Disconnect the spark plug wire, and keep the wire away from the plug to prevent accidental starting. Disconnect the cord on electric motors.
•Do not run the engine indoors; exhaust fumes are dangerous.

OPERATION
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 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.
IMPORTANT: WHEN OPERATING IN TEMPERATURES BELOW32°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 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.
TO START ENGINE (See Fig. 13)
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 the fuel valve to the "ON" position.
3.To start a cold engine, move the choke lever to the "ON" position.
4.Move the throttle lever away from the "SLOW" position, about 1/3 of the way toward the "FAST" position.
5.Turn the engine switch to the "ON" position. Pull rope out slowly until engine reaches start of compression cycle (rope will pull slightly harder at this point).
6.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.
7.If the choke lever has been moved to the "ON" position to start the engine, gradually move it to the opposite position as the engine warms up.
NOTE: A WARM ENGINE REQUIRES LESS CHOKING TO START.
8.Move throttle control to desired running position.
9.Allow engine to warm up for a few minutes before engaging tines.
NOTE: IFENGINEDOESNOTSTART,SEE TROUBLESHOOTING POINTS.

OPERATION
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”).
•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 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.
•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. Second, the tiller won’t be pulling itself, and you, toward the row next to it.
•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.
•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.

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
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 Adjustments 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 transmission.
•If shear pin(s) break, replace only with those shown in the Repair Parts section of this manual.

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. 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 tine operation.
•Check for loose fasteners.

Fig. 16
NOTE: Although multi-viscosity oils (5W-30, 10W-30, etc.) improve starting in cold weather, these multi-viscosity oils will result in increased oil consumption when used above 40°F (4°C). 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.
TO CHANGE ENGINE OIL (See Figs. 16 and 17)
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.
•Use a funnel to prevent oil spill on tiller, and catch oil in a suitable container.
•Remove drain plug. For easier removal of plug use 7/16 12 Pt. socket with extension.)
•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.

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 25 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 the transmission 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.
