injuryor death. TRAINING

Readthe Owner's Manualcarefully.Be thoroughlyfamiliar withthe controlsand the proper use ofthe equipment.Know

howto stopthe unit anddisengagethe controlsquickly.

Neverallow childrento operatethe equipment. Never allowadultsto op-

erate the equipmentwithout proper

instruction.

Keepthe area of operationclear of all

persons,particularlysmall children, and

pets.

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 (mo-

tor). 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 flam-

mable. 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 elec-

tric starting motors.

• Never attempt to make any adjustments while the engine (motor) is running (ex-

cept where specifically recommended by manufacturer).

OPERATION

, Do not put hands or feet near or under

rotating parts.

• Exercise extreme caution when operat-

ing 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 fall-

ing.

If the unit should start to vibrate ab-

normally, stop the engine (motor) and

check immediately for the cause. Vibra- tion is generally a warning of trouble.

Stop the engine (motor) when leaving the operating position.

Take all possible precautions when leav-

ing 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.

, Never operate the tiller without proper

guards, plates, or other safety protective devices in place.

, Keep children and pets away.

• Do not overload the machine capacity

by attempting to till too deep at too fast a rate.

• Never operate the machine at high speeds on slippery surfaces. Look be- hind and use care when backing.

• Never allow bystanders near the unit. Use only attachments and accessories approved by the manufacturer of the

tiller. Never operate the tiller without good vis-

ibility 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.

MAINTENANCE AND STORAGE

• Keep machine, attachments, and ac- cessories in safe working condition. Check shear pins, engine mounting

bolts, and other bolts at frequent inter- vals for proper tightness to be sure the equipment is in safe working condition.

Never store the machine with fuel in the fuel tank inside a building where ignition

sources are present, such as hot water and space heaters, clothes dryers, and

the like. Allow the engine to cool before storing in any enclosure. Always refer to the operator's guide instructions for important details if the

tiller is to be stored for an extended period.

will not turn.

4. Move throttle control to desired speed.

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. CHECK ENGINE OIL LEVEL

The engine in your unit has been shipped, from the factory, already filled with SAE 30

summer weight oil.

1. With engine level, clean area around oil filler plug and remove plug.

2. Engine oil should be to point of over- flowing when engine is level.

, For approximate capacity see "PROD-

UCT SPECIFICATIONS" on page 3 of this manual. All oil must meet A.RI.

Service Classification SF-SJ.

, For cold weather operation you should

change oil for easier starting (See oil

viscosity chart in the Maintenance sec-

tion of this manual).

, To change engine oil, see the Mainte-

nance section in this manual.

Oil Fill

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 depos-

its and reduce valve life). Do not mix oil with gasoline. Purchase fuel in quan- tities that can be used within 30 days to

assure fuel freshness.

A(_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 temper- atures 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 separa-

tion 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

_,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.

1. Make sure spark plug wire is properly connected.

2. Move shift lever indicator to "N" (neu- tral) position.

3. Place throttle control in "FAST" posi- tion.

4. Turn fuel shut-off valve 1/4 turn to open

position.

5. Move choke control to choke position.

6. 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).

7. Pull recoil starter handle quickly. Do

not let starter handle snap back

against starter.

NOTE: If engine fires but does not start, move choke control to half choke posi-

tion. Pull recoil starter handle until engine starts.

8. When engine starts, slowly move choke control to "RUN" position as

engine warms up.

NOTE: A warm engine requires less choking to start.

9. Move throttle control to desired running

position.

10.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 trou-

bleshooting points.

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 plant-

ing. 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. 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 mois- tened before tilling; however, extremely wet soil will "ball-up" or clump during till-

ing. 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.There are two reasons for doing this. First,

wide turns are much easier to negoti- ate than about-faces. Second, the tiller

won't be pulling itself, and you, toward the row next to it.

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.

• 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.

C iC IC

ADJUST WHEELS FOR CULTIVATING

1. Place blocks under right hand side of tiller and remove hairpin clip and clevis

pin from right hand wheel.

2. Move wheel outward approximately 1 inch until hole in inner wheel hub lines

up with inner hole in axle.

3. Replace clevis pin and hairpin clip on inside of wheel and remove blocks.

4. Repeat preceding steps on left hand

side.

NOTE: In extremely rough conditions and

while cultivating, the wheels should be

moved outward on the axle for increased

stability.

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 op- erator 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.

At least once a season, check to see if

you should make any of the adjustments described in the Service and Adjustments

section of this manual. * At least 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 as-

sure proper air-fuel mixture and help your engine run better and last longer.

BEFORE EACH USE

1. Check engine oil level.

2. Check tine operation.

NOTE: Although multi-viscosity oils (5W-30, 10W-30, etc.) improve starting in

cold weather, they will result in increased oil consumption when used above 32°F

(0°C). Check your engine oil level more

frequently to avoid possible engine dam-

age 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 mo- tor oil or equivalent. Tighten oil filler plug

securely each time you check the oil level.

5. Refill engine with oil. See "CHECK ENGINE OIL LEVEl" in the Operation

section of this manual.

Determine temperature range expected before oil change. All oil must meet API

service classification SF-SJ.

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.

1. Remove drain plug.

2. Tip tiller forward to drain oil.

3. After oil has drained completely, replace oil drain plug and tighten se- curely.

4. Remove oil filler plug. Be careful not to allow dirt to enter the engine.

COOLING SYSTEM

Your engine is air cooled. For proper en-

gine performance and long life keep your engine clean. , Clean air screen frequently using a stiff-

bristled brush.

• Keep cylinder fins, levers, and linkage free of dirt and chaff.

Housing

Air Screen

Muffler

MUFFLER Do not operate tiller without muffler. Do

not tamper with exhaust system. Dam- aged 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 as-

sembly, remove every 50 hours for clean- ing 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 is shown in "PROD-

UCT SPECIFICATIONS" on page 4 of this manual.

TRANSMISSION Once a season, lubricate the right hand

gear case grease fitting with 1 oz. of EP #1 grease.

CLEANING

Do not clean your tiller when the engine

and transmission are hot. We do not rec- ommend 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 auto-

motive type wax.

_CAUTION: Disconnect spark plug wire from spark plug and place wire where it

cannot come into contact with plug.

TILLER

TO ADJUST HANDLE HEIGHT

Select handle height best suited for your tilling conditions. Handle height will be

different when tiller digs into soil.

1. First loosen handle lock lever.

2. Handle can be positioned at different settings between "HIGH" and "LOW"

positions.

3. Retighten handle lock lever securely after adjusting.

TIRE CARE A(_CAUTION: 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

1. Place blocks under transmission to keep tiller from tipping.

2. Remove hairpin clip and clevis pin from

wheel.

3. Remove wheel and tire.

4. Repair tire and reassemble.

2. Remove old belt by slipping off engine pulley first then remove from trans- mission pulley.

3. Place new belt in groove of trans- mission pulley and into engine pulley.

BELT MUST BE IN GROOVE ON TOP OF IDLER PULLEY. NOTE POSITION OF BELT TO GUIDES.

4. Check belt adjustment as described below.

5. Replace belt guard.

6. Reposition wheel and replace clevis pin and hairpin clip.

GROUND DRIVE BELT ADJUSTMENT

For proper belt tension, the extension

spring should have about 5/8 inch stretch when drive control bar is in "ENGAGED"

position. This tension can be attained as

follows:

1. Loosen cable clip screw securing the drive control cable.

2. Slide cable forward for less tension and rearward for more tension until about 5/8 inch stretch is obtained while the drive control bar is engaged.

3. Tighten cable clip screw securely.

TINE REPLACEMENT

_CAUTION: Tines are sharp. Wear

gloves or other protection when handling tines.

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.

New Tine

Worn Tine

• To maintain the superb tilling perfor- mance of this machine 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. Sharp-

ened tine edges will rotate rear
