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.P.I.

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

Filler Plug

Drain Plug

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.

_CAUTION: Fill to within 1/2 inch of top of fuel tank to prevent spills and to allow for fuel expansion. If gasoline is acci-

dentally spilled, move machine away from area of spill. Avoid creating any source of

ignition until gasoline vapors have disap- peared.

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.

See "TO ADJUST CARBURETOR" in the Service and Adjustments section of this

manual. NOTE: If engine does not start, see trou-

bleshooting points.

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.

5. Move choke control to choke position.

5. 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).

6. 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.

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

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.

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.

AMBIENT TEMPERATURE

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 40°F

(4°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.

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.

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.

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

section of this manual.

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 _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.

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 _L,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.
