TINES

® Release forward tine control to stop forward move

ment.

® Release reverse tine control to stop reverse move

ment.

ENGINE

« Move throttle control to “STOP” position.
* Never use choke to stop engine.

TILLING

The speed and depth of tilling is regulated by the position
of the depth stake and wheel height.

The depth stake should always be below the wheeis for
digging. It serves as a brake to slow the tiller’s forward
motion to enable the tines to penetrate the ground. Also,
the more the depth stake is lowered into the ground the
deeper the tines will dig.

DEPTH STAKE (See Fig. 6)
Adjust depth stake by removing the hairpin clip and clevis

pin. Change depth stake to desired position. Replace the
clevis pin and hairpin clip.

» For normal tilling, set depth stake at the second orthird

hole from the top.

WHEELS (See Fig. 6)

Adjust wheels by removing the hairpin clip and clevis pin.
Change wheel position. Replace the hairpin clip and clevis
pin.

STARTING.

WARNING: Experience indicates that alcohol blended
fuels (called gasoho! 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 white in storage. To avoid engine

probiems, 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 tines and carburetor are
empty. Use fresh fuel next season. See Storage section
of this manual for additional information. Never use engine
or carburetor cleaner products 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
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.

TO START ENGINE (See Fig. 8)

CAUTION: Keep tine control In “OFF”

A

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

» Make sure spark plug wire is properly connected.
* Place throttle control in “FAST” position.
* Move choke control to full “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 compression cycle (rope will
pull slightly harder at this point).

* Pull recoil starter handle quickly. Do not let starter

handle snap back against starter. Repeat if necessary.
If engine fires 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 tempera

tures (below 32°F), the carburetor fuel mixture may need to
be adjusted for best engine performance. See “TO AD

OPERATION

BREAKING IN YOUR TILLER

Break-in your beit{s), pulleys and tine control before you
actually begin tilling.

® Start engine, tip tines off ground by pressing handles

down and engage tine control to start tine rotation.
Allow tines to rotate for five minutes.

« Check tine operation and adjust if necessary. See

“TINE OPERATION CHECK" in the Service and Ad
justments section of this manual.

TILLING HINTS

CAUTION: Until you are accustomed to
handling your tiller, start actual field

A

To help tiller move forward, lift up the handles slightly (thus

lifting depth stake out of ground). To slow down the tiller,

press down on handles.

If you are straining or tiller is shaking, the wheels and depth
stake are not set properly In the soil being tilled. The proper
setting of the wheels and depth stake is through trial and
error and depends upon the soil condition. (The harder or
wetter the ground, the slower the engine and tine speed
needed. Underthese poorconditions, affasi speed the tiller

will run and jump over the ground).

A properly adjusted tiller will dig with little effort from the

operator.
9 Tilling is digging into, turning over, and breaking up

packed soil before planting. Loose, unpacked soil
helps root gro\vth. Best tilling depth is 4"-6". A tiller will
also clear the soil of unwanted vegetation. The decom
position 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 contrib
ute 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 inthefall, remove
vines and long grass to prevent them from wrapping
around the tine shaft and slowing your tilling operation.

use with throttle in slow position.

You will find tilling much easier if you leave a row
unfilled between passes. Then go back between tilled

rows. (See Fig. 9) There are two reasons for doing this.
First, wide turns are much easier to negotiate than
about-faces. Second, the tiller won’t be pulling itself,

and you, toward the row next to it.

Set depth stake and wheel height for shallow tilling
when working extremely hard soil or sod. Then work
across the first cuts at normal depth.

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 soli crust will help retain moisture in the soil. Best
digging depth is T’-3".

* You will probably not need to use the depth stake.

Begin by tipping the depth stake forward until it is held
by the stake spring.

® 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. 10).

to relieve spring tension. Tighten cable clip.

Recheck in “OFF” position and adjust if necessary.

FINAL CHECK “ON” POSITION

With tine control “ON” (held down to handle) push down
on handle to raise tines off the ground.

Slowly pull recoil starter handle while observing tines.
Tines should rotate forward,

if tines do not rotate, inner wire of control cable is too

loose. Loosen cable clip and pull cable up to remove

slack and retighten clip.

Recheck in “ON” position and adjust if necessary.

NOTE: If “ON” position check required adjustment, re­check “OFF” position adjustment to insure tines do not

SERVICE AND ADJUSTMENTS

ENGINE

TO ADJUST CARBURETOR

The Carburetor has a hi^ speed fixed jet and has been

preset at the factory and adjustment should not be neces
sary. However, minor adjustments may be required to
compensate for differences in fuel, temperature, altitude or
load. If the carburetor does need adjustment, see engine
manual.

High speed stop is factory adjusted,

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.

Do not adjust or

15

STORAGE

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.

CAUnON; Never store the tiller with
gasoline in the tank inside a building

A

M m

where fumes may reach an open flame
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 all nuts, bolts and screws are securely

fastened, inspect moving parts for damage, breakage

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 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 !N STORAGE.

• Drain the fuel tank.
» Start 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 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.

ENGINE OIL

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

CYUNDEB(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 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.
