STOPPING (See Fig. 5)
TINES
» Release forward tine control to stop forward move
ment.
® Release reverse tine control to stop reverse tine move
ment.
ENGINE
» Move throttle control to "STOP” position.
9 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 wheels 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 dip.
» For normal tilling, set depth stake at the second orthird
hole from the top.
WHEELS (See Fig. 6)
Adjust wheels by removing the hairpin dip and clevis pin.
Change wheel position. Replace the hairpin dip and clevis
pin.

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 iet 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
orcarburetor cleaner products in the fuel tankor 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

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, at fast speed the tiller
will run and jump over the ground).
A property adjusted tiller will dig with little effort from the
operator.
® 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 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 importantfor propertilling. 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 “bal!-up" or clump
during tilling. Wait until the soil is less wet in order to
achieve the best results. When tilling in the fail, remove
vines and long grass to prevent them from wrapping
around the tine shaft and slowing your tilling operation.
handling your tiller, start actual field
use with throttle In slow position (mid
way between “FAST” and “IDLE”).
You will find tilling much easier If you leave a row
untilled 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 soil crust will help retain moisture in the soil. Best
digging depth is 1” to 3” (2.5-7.5 cm).
« 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).

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
THEFUELSYSTEMOFAN 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 orcarburetorcleanerproducts 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.
