BEFORE STARTING ENGINE

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. 12)

Fig. 12

1. Remove hangtag from engine.
2. With engine level, remove engine oil fill er plug.
3. Fill engine with oil to point of overflowing. For approximate capacity see "PRODUCT SPECIFICATIONS". All oil must meet A.P.I. Service Classification SG-SL.
4. Tilt tiller back on its wheels and then re-level.
5. With engine level, refill to point of over flowing 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.

ADD GASOLINE

• Fill fuel tank to bottom of filler neck. Do not overfill. Use fresh, clean, regular un lead ed 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.

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.

WHEN OPERATING IN TEMPERATURES BELOW 32°F(0°C), USE FRESH, CLEAN WINTER GRADE GASOLINE TO HELP INSURE GOOD COLD WEATHER STARTING.

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 stor age 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.

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 min utes before engaging tines.

NOTE: IF ENGINE DOES NOT START, SEE TROUBLESHOOTING POINTS.

TILLING HINTS

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 (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. Second, the tiller won't be pulling itself, and you, toward the row next to it.
  
  Fig. 14
• 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, 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.

CULTIVATING

Cultivating is destroying the weeds between rows to pre vent 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.

MAINTENANCE

1. Charge 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 main tain 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.

LUBRICATION

Keep unit well lubricated (See "LUBRICATION CHART").

LUBRICATION CHART

1. SAE 30 OR 10W-30 MOTOR OIL
2. REFER TO MAINTENANCE "ENGINE" SECTION
3. EP #1 GREASE

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. Select the oil's SAE viscosity grade according to your expected temperature.

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)

Fig. 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.

AIR CLEANER

(See Fig. 18)

Fig. 18

Service air cleaner cartridge every twenty-five 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 by tapping gently on a flat surface.

NOTE: If very dirty or damaged, replace cartridge.

5. Clean and replace cover. Tighten screw securely.

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.

COOLING SYSTEM

(See Fig. 19)

Fig. 19

Your engine is air cooled. For proper engine performance and long life keep your engine clean.

• Clean air screen frequently using a stiff-bristled 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 25 hours of use, whichever comes first. Spark plug type and gap setting are shown in "PRODUCT SPECIFICATIONS".

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 (gar den hose, etc.) to clean your unit un less 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.

SERVICE AND ADJUSTMENTS

Disconnect spark plug wire from spark plug and place wire where it cannot come into contact with plug.

TILLER

TO ADJUST HANDLE HEIGHT

(See Fig. 20)

Fig. 20

Select handle height best suited for your tilling conditions. Handle height will be different when tiller digs into soil.

• First loosen handle lock lever.
• Handle can be positioned at different settings between "HIGH" and "LOW" positions.
• Retighten handle lock lever securely after adjusting.

ENGINE

Maintenance, repair, or replacement of the emission control devices and systems, which are being done at the customers expense, may be performed by any non-road engine repair establishment or individual. Warranty repairs must be performed by an authorized engine manufacturer's service outlet.

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 THINK THE ENGINE-GOVERNED HIGH SPEED NEEDS ADJUSTING, CONTACT YOUR NEAREST AUTHORIZED SERVICE CENTER/DEPARTMENT, WHICH HAS THE PROPER EQUIPMENT AND EXPERIENCE TO MAKE ANY NECESSARY ADJUSTMENTS.

TIRE CARE

When mounting tires, unless beads are seated, overinflation can cause an explosion.

• Maintain 20 pounds of tire pressure. If tire pressures are not equal, tiller will pull to one side.
• Keep tires free of gasoline or oil which can damage rubber.

TO REMOVE WHEEL

(See Fig. 21)

Fig. 21

• Place blocks under transmission to keep tiller from tipping.
• Remove hairpin clip and clevis pin from wheel.
• Remove wheel and tire.
• Repair tire and reassemble.

A badly worn tine causes your tiller to work harder and dig more shallow. Most important, worn tines cannot chop and shred organic matter as effectively nor bury it as deeply as good tines. A tine this worn needs to be replaced.

• To maintain the superb tilling performance of this ma chine the tines should be checked for sharpness, wear, and bending, particularly the tines which are next to the transmission. If the gap between the tines exceeds 3-1/2 inches they should be replaced or straightened as necessary.
• New tines should be assembled as shown in Fig. X3. Sharpened tine edges will rotate rearward from above.

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.

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, break age and wear. Replace if necessary.
• Touch up all rusted or chipped paint surfaces; sand lightly before painting.

ENGINE

FUEL SYSTEM

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 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" in the Maintenance section of this manual).

CYLINDER(S)

• 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

• 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.

NEVER COVER TILLER WHILE ENGINE AND EXHAUST AREAS ARE STILL WARM.
