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

overflowing when engine is level.

• For approximate capacity see "PROD-

UCT SPECIFICATIONS" on page 4 of

this manual. All oil must meet A.P.I.

Service Classification SF-SJ.

• 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 Mainte-

nance section in this manual.

Oil Fill

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 tem- peratures below 32°F(0°C), use fresh,

clean, winter grade gasoline to help

insure good cold weather starting.

AWARNING: 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 empty. Use fresh fuel next season, See Storage section of this

manual for additional information. Never use engine or carburetor cleaner prod-

ucts in the fuel tank or permanent damage may occur. 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 acciden- tally 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.

TO START ENGINE

_,CAI.n'ION: Keep drive controlbar in

"DISENGAGED" positionwhen starting

engine. When starting engine for the firsttime or if engine has run out of fuel, it will take

extra pullsof the recoil starter to move fuel from the tank to the engine.

1. Make sure spark plug wire is properly connected.

2. Move shiftlever indicator to "N"

(neutral) position.

3. Place throttle control in "FAST"

position.

4. Turn fuel shut-offvalve 1/4 tum 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 letstarter handle snap back against starter.

NOTE: If engine fires but does not start, move choke control to half choke position.

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 chokingto 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 highaltitude (3000 feet) or

in cold temperatures (below 32°1=),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.

TILLING HINTS

_aaCAUTION: Until you are accustomed to

ndling 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".

A tiller will also clear the soil of un- wanted 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 line 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.Them are two reasons for doing

this. First, wide turns are much easier to

negotiate than about-taces. 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.

Choke Control

Starter Handle 11

_ ADJUSTWHEELS FOR

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.

CULTIVATING

• 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.

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 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 OIL

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.

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 "line

• 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.

Sharpened tine edges will rotate rearward from above.
