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 (See Fig. 12)

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

factory, already filled with SAE 30 summer weight oil.

» With engine level, dean area around oil filler plug and

remove plug.

® Engine oil should be to point of overflowing. For

approximate capacity see “PRODUCT SPECIFICA­TiONS” on page 3 of this manual. All oil must meet
A.P.I. Service Classification SF or SG.

» For cold weather operation you should change oil for

easier starting (See oil viscosity chart in the Customer
Responsibiiities section of this manual).

® To change engine oii, see the Customer Responsibiii-

ties section in this manual.

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 TEMPERATURES
BELOW 32“F(0"C), USE FRESH, CLEAN, WINTER GRADE
GASOLINE TO HELP INSURE GOOD COLD WEATHER
STARTING.

WARNING: 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 carbureior are
empty. Use fresh fuel next season. See Storage section
of this manual for additional information. Never use engine
orcarburetorcleanerproducts in the fuel tank or permanent
damage may occur.

CAUTION: Fill to within 1/2 inch of top
of fuel tank to prevent spills and to

A

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.

Do not overfill. Wipe off any spilled oil
or fuel. Do not store, spill or use gaso
line near an open flame.

10

OPERATION

TO START ENGINE (See Fig. 13)

CAUTION: Keep drive control bar in
“DISENGAGED” position when start
ing engine.

When starting engine for the first time or if engine has run
out of fuel, it WÜ! take extra pulls of the recoil starter to move
fuel from the tank to the engine,

o Make sure spark plug wire is properly connected.
® Move shift lever indicator to “N” (neutral) position.
® Piace throttle control in “FAST” position.
« With engine fully choked, grasp recoil starter handle

with one hand and grasp tiller handle with other hand.

Pull rope out slowly until engine reaches start of com
pression cycle (rope will puli slightly harder at this
point).

« Pu!! recoil starter handle quickly. Do not let starter

handle snap back against starter. Repeat if necessary
in half choked position.

« 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 (above 3000 feet) or in cold
temperatures (below 32°F), the carburetor fuel mixture
may need to be adjusted lor best engine performance. See
TO ADJUST CARBURETOR” in the Service and Adjust
ments section of this manual.

NOTE: if engine does not start, see troubleshooting 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 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 mat
ter enriches the soil. Depending on the climate (rainfall
and wind), it may be advisabie to till the soil at the end
of the growing season to further condition the soil.

Soil conditions are importantfor propertiiling. Tines will

not readily penetrate dry, hard soil which may contrib

ute to excessive bounce and difficult handling of your
tiller. Hard soil should be moistened before tilling;
however, extremely wet soil wHI “ball-up” or clump
during tilling. Wait until the soil is less wet in order to
achieve the best resuits. When tilling in the fall, remove
vines and long grass to prevent them from wrapping
around the tine shaft and slowing your tilling operation.

For easier handling of your tiller, leave about 8 inches
(20 cm) of uniilied soil between the first and second
tilling passes. The third pass will be between the first
and second (See Fig. 14).

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.

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.

11

OPERATION

CULTIVATING

Cultivating is destroying the v^eeds 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),

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
maintain tiller as instructed in this manual.

Some adjustments will need to be made periodically to
properly maintain your tiller.

A!! 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.

(See Fig. 29)

» Loosen cable damp screw to allow cable to move.
® Move throttle control lever on upper handle to “FAST”

position,

* Pull throttle cable out until engine bellcrank is back as

far as it will go.

• Hold cable In this position and tighten clamp screw
securely.

TO ADJUST CARBURETOR (See Fig. 30)

The carburetor has a high speed jet and has been preset at
the factory and adjustment should not be necessary. How

ever, minor adjustments may be required to compensate
for differences in fuel, temperature, altitude or load. If the
carburetor does need adjustment, proceed as follows.

In general, turning the idle needle valve in (clockwise)
decreases the supply of fuel to the engine giving a leaner
fuel/air mixture. Turning the needle valve out (counter
clockwise) increases the supply of fuel to the engine giving
a richer fuel/air mixture.

IMPORTANT: DAMAGE TO THE NEEDLES AND THE
SEATS IN CARBURETOR MAY RESULT IF SCREWS ARE
TURNED IN TOO TIGHT.

PRELIMINARY SETTING

» Air cleaner assembly must be assembled to the carbu

retor when making carburetor adjustments.

* Be sure the throttle control cable is adjusted properly

(see above).

“ With engine off, turn idle needle valve in (clockwise)

closing it finger tight and then turn valve out (counter
clockwise) 1 "1/2 turns.

FINAL SETTING

» Start engine and allow to warm for five minutes. Make

final adjustments with engine running at idle and drive
contro! bar in “DISENGAGED” position.

® With throttle control lever in “SLOW" position, turn idle

needle valve in (clockwise) until engine begins to die

then turn out (counterclockwise) until engine runs

rough. Turn vaive to a point midway between those two

positions.
IDLE RPM ADJUSTMENT
® To adjust idle RPM, rotate throttle linkage counter

clockwise and hold against stop while adjusting idle
speed adjusting screw to obtain 1750 RPM. Release
throttie linkage.

ACCELERATION TEST

* Move throttle control lever from “SLOW" to “FAST"

position, If engine hesitates or dies, turn needle valve

out (counterclockwise) 1/8 turn. Repeat test and
continue to adjust, if necessary, until engine acceler
ates smoothly.

High speed stop is factory adjusted. Do not adjust or

damage may result.

IMPORTANT: 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.

18

STORAGE

Immediaieiy prepare your tiller for storage at the end of the

season or if the unit will not be used for 30 days or more.

CAUTION: Never store the tiller with
gasoline in the tank inside a building
where fumes may reach an open flame

A

or spark. Allow the engine to cool
before storing in any enclosure.

TILLER

* Clean entire tiller (See “CLEANING” in the Customer

Responsibilities section of this manual).

* Inspect and replace belts, if necessary (See belt re

placement instructions in the Service and Adjustments
section of this manual).

» Lubricate as shown in the Customer Responsibilities

section of this manual.

* Be sure that ail nuts, bolts and screws are securely

fastened. Inspect moving parts for damage, breakage
and wear. Replace if necessary.

“ Touch up al! rusted or chipped paint surfaces; sand

lightly before painting,

ENGINE

ENGINE OIL

Drain oi! (with engine warm) and replace with clean oil.
(See “ENGINE” in the Customer Responsibilities section of

this manual).

CYUNDERS

» Remove spark plug.
® Pour 1 ounce (29 ml) of oil through spark plug hole Into

cyiinder.
“ 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.

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

FUEL SYSTEM

IMPORTANT: 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.

» Drain the fuel tank.
“ Start the engine and let it run until the fuel lines and

carburetor are empty.

« Neveruse engine or carburetor cleaner products in the

fuel tank or permanent damage may occur.

* Use fresh fuel next season.

NOTE: Fuel stabilizer is an acceptable alternative In
minimizing the formation of fuel gum deposits during stor
age. 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 drain the gas tank and carburetor if using fuel stabilizer.
