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

AP PROVED, CLEAN, COVERED CONTAINERS. USE CLEAN

FILL FUNNELS.

CHECK ENGINE OIL LEVEL (See Fig.12)

• The engine in your unit has been shipped, from the

factory, already ﬁ lled with SAE 30 summer weight oil.

• With engine level, clean area around oil ﬁ ller plug and

remove plug.

• Engine oil should be to point of overﬂ owing when engine

is level. For ap proxi mate capacity see “PROD UCT

SPEC I FI CA TIONS” on page 3 of this manual. All oil

must meet A.P.I. Service Classiﬁ cation SF-SJ.

• For cold weather operation you should change oil for

easier starting (See oil viscosity chart in the Mainte-

nance sec tion of this manual).

• To change engine oil, see the Maintenance section in

this manual.

TO START ENGINE (See Fig. 13)

CAUTION: Keep drive control bar in

“DISENGAGED” position when start-

ing en gine.

When starting engine for the ﬁ rst 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.

• Make sure spark plug wire is prop er ly connected.

• Move shift lever indicator to “N” (neutral) position.

• Place throttle control in “FAST” position.

ADD GASOLINE

• Fill fuel tank to bottom of ﬁ ller neck. Do not overﬁ ll.

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 quan ti ties 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 ac-

ci den tal ly 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 ﬂ ame.

IMPORTANT: WHEN OPERATING IN TEMPERATURES

BELOW32°F(0°C), USE FRESH, CLEAN WINTER GRADE

GAS O LINE TO HELP INSURE GOOD COLD WEATHER

START ING.

CAUTION: Alcohol blended fuels (called

gas o hol or using ethanol or methanol) can at-

tract moisture which leads to sep a ra tion and

for ma tion 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

sea son. See Storage In struc tions for additional

information. Never use engine or carburetor

cleaner products in the fuel tank or permanent

damage may occur.

• When you have completed your turn-around, release

the drive control bar and lower handle. Place shift

lever in till position and move throttle control to de sired

speed. To begin tilling, hold drive control bar against

the handle.

OUTER SIDE SHIELDS (See Fig. 11)

The back edges of the outer side shields are slotted so

that the shields can be raised for deep tilling and low ered

for shal low tilling to protect small plants from being buried.

Loosen nut “A” in slot and nut “B”. Move shield to desired

position (both sides). Retighten nuts.

TO TRANSPORT

CAUTION: Before lifting or trans port ing,

allow tiller engine and mufﬂ er to cool.

Disconnect spark plug wire. Drain

gasoline from fuel tank.

AROUND THE YARD

• Release the depth stake pin. Move the depth stake

down to the top hole for transporting the tiller. Place

depth stake pin in hole of depth stake to lock in posi-

tion. This prevents tines from scufﬁ ng the ground.

• Place shift lever indicator in “F” (forward) position for

transporting.

• Hold the drive control bar against the handle to start

tiller movement. Tines will not turn.

• Move throttle control to desired speed.

AROUND TOWN

• Disconnect spark plug wire.

• Drain fuel tank.

• Transport in upright position to prevent oil leakage.

10

RUN

CHOKE

OPERATION

• Soil conditions are important for proper tilling. Tines will

not readily penetrate dry, hard soil which may con trib ute

to excessive bounce and difﬁ cult handling of your tiller.

Hard soil should be mois tened 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.

FIG. 14

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

TILLING HINTS

CAUTION: Until you are accustomed to

handling your tiller, start actual ﬁ eld 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 vege ta tion.

The de com po si tion of this vegetable mat ter 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 ﬁ nd tilling much easier if you leave a row un-

tilled 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. Sec ond, the tiller won’t be pulling itself,

and you, toward the row next to it.

FIG. 13

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 Ad just ments 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 trans mis sion.

• If shear pin(s) break, replace only with those shown in

the Repair Parts section of this manual.

CHOKE CONTROL

RECOIL STARTER HANDLE

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

• Move choke control to choke position.

• Grasp recoil starter handle with one hand and grasp

tiller handle with other hand. Pull rope out slowly until

engine reaches start of com pres sion cycle (rope will

pull slightly harder at this point).

• Pull recoil starter handle quickly. Do not let starter

handle snap back against starter.

• If engine ﬁ res but does not start, move choke control

to half choke position. Pull recoil starter handle until

engine starts.

• When engine starts, slowly move choke control to

"RUN" position as engine warms up.

NOTE: A warm engine requires less choking to start.

• Move throttle control to desired running position.

• Allow engine to warm up for a few minutes before

engaging tines.

NOTE: If at a high altitude (3000 feet) or in cold tem per a tures

(below 32°F), the carburetor fuel mixture may need to be

adjusted for best engine performance. See "TO AD JUST

CARBURETOR" in the Service and Adjustments section

of this manual.

NOTE: If engine does not start, see troubleshooting

points.

MAINTENANCE

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 ﬁ lter, and check tines and belts for wear.

A new spark plug and clean air ﬁ lter 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. 17

TO CHANGE ENGINE OIL (See Figs. 16 and 17)

Determine temperature range expected before oil change.

All oil must meet API service classiﬁ cation 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 con tain er.

• 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 ﬁ ller plug. Be careful not to allow dirt to

enter the engine.

• Reﬁ ll engine with oil. See “CHECK ENGINE OIL LEVEL”

in the Operation section of this manual.

ENGINE

LUBRICATION

Use only high quality detergent oil rated with API service

classiﬁ cation SF-SJ. Select the oil’s SAE vis cos i ty grade

according to your expected temperature.

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 ﬁ ve (5) hours of continuous use. Add SAE

30 motor oil or equivalent. Tighten oil ﬁ ller plug securely

each time you check the oil level.

MUFFLER

Do not operate tiller without mufﬂ er. Do not tamper with

exhaust system. Damaged mufﬂ ers or spark arresters could

create a ﬁ re hazard. Inspect pe ri odi cally and re place if

nec es sary. If your engine is equipped with a spark arrester

screen assembly, re move every 50 hours for cleaning and

inspection. Re place if dam aged.

SPARK PLUG

Replace spark plugs at the beginning of each tilling sea-

son or after every 50 hours of use, whichever comes ﬁ rst.

Spark plug type and gap setting is shown in “PRODUCT

SPEC I FI CA TIONS” on page 3 of this manual.

TRANSMISSION

Once a season, lubricate the right hand side gear case

grease ﬁ tting with 1 oz. of EP #1 Grease.

CLEANING

Do not clean your tiller when the engine and transmission

are hot. We do not rec om mend using pressurized water

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

area around the trans mis sion and the engine muf ﬂ er, air

ﬁ l ter and car bu re tor are cov ered to keep wa ter out. Wa ter

in en gine will short en the useful life of your tiller.

• Clean engine, wheels, ﬁ nish, etc. of all foreign mat-

ter.

• Keep ﬁ nished surfaces and wheels free of all gas o line,

oil, etc.

• Protect painted surfaces with au to mo tive type wax.

have about 5/8 inch stretch when drive control bar is in

“EN GAGED” position. This tension can be attained as

follows:

• Loosen cable clip screw securing the drive control

cable.

• 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.

• Tighten cable clip screw securely.

TINE REPLACEMENT

(See Figs. 24, 25, and 26)

CAUTION: Tines are sharp. Wear

gloves or other protection when han-

dling 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.

FIG. 25

• 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

ex ceeds 3-1/2 inches (9 cm), they should be replaced

or straight ened as necessary.

• New tines should be assembled as shown in Fig.

26. Sharp ened tine edges will rotate rearward from

above.

TO ADJUST THROTTLE CONTROL CABLE

(See Fig. 27)

The throttle control has been preset at the factory and

ad just ment should not be necessary. If adjustment is

necessary, proceed as follows:

• With engine not running, move remote throttle control

lever to “FAST” position.

• If throttle lever on engine touches high speed stop, no

further adjustment is necessary. If throttle lever does

not touch high speed stop, continue with adjustment

procedure.

• Loosen cable clamp screw.

• Move throttle lever up until it touches high speed stop,

and hold in this position.

• Tighten cable clamp screw securely.

TO AD JUST CARBURETOR

The carburetor has been preset at the factory and ad just ment

should not be necessary. However, engine per for mance

can be affected by dif fer enc es in fuel, tem per a ture, al ti tude

or load. If the carburetor does need ad just ment, contact

your nearest authorized service center/de part ment

IMPORTANT: NEVER TAMPER WITH THE ENGINE GOVERNOR,

WHICH IS FACTORY SET FOR PROPER ENGINE SPEED.

OVER SPEED ING 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 EQUIP MENT AND

EXPERIENCE TO MAKE ANY NEC ES SARY ADJUSTMENTS.

18

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.

WARNING: Never store the tiller with

gasoline in the tank inside a build ing

where fumes may reach an open ﬂ ame

or spark. Allow the engine to cool before

storing in any en clo sure.

TILLER

• Clean entire tiller (See “CLEANING” in the Maintenance

section of this manual).

• Inspect and replace belts, if necessary (See belt re-

place ment instructions in the Service and Ad just ments

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

IMPORTANT: IT IS IMPORTANT TO PREVENT GUM DEPOSITS

FROM FORMING IN ES SEN TIAL FUEL SYS TEM PARTS SUCH

AS THE CAR BU RE TOR, FUEL FILTER, FUEL HOSE, OR TANK

DURING STOR AGE. ALSO, EXPERIENCE INDICATES THAT

AL CO HOL BLENDED FUELS (CALLED GASOHOL OR USING

ETHA NOL OR METHA NOL) CAN ATTRACT MOIS TURE WHICH

LEADS TO SEPA RA TION AND FORMATION OF ACIDS DUR ING

STOR AGE. ACIDIC GAS CAN DAMAGE THE FUEL SYSTEM

OF AN ENGINE WHILE IN STOR AGE.

• 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 stablizer 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 stablizer

container. Run engine at least 10 minutes after adding

stablizer 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 man ual).

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 an-

other.

• 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.

IMPORTANT: NEVER COVER TILLER WHILE EN GINE AND

EX HAUST AREAS ARE STILL WARM.
