• Push tiller handles down, raising tines
off the ground.
• Push or pull tiller to desired location.
AROUND TOWN
TINE OPERATION
• Squeeze tine control to handle.
TILLING
The speed and depth of tilling is regulated
by the position of the depth stake and
wheel height.
• Disconnect spark plug wire.
• Drain fueltank.
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.
• Transport in upright position to prevent
oil leakage.
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.
DEPTH STAKE
FILL ENGINE
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 or third hole from the top.
• Remove hang tag from engine.
With engine level remove engine oil

• Tilttillerbackon itswheelsandthen relevel.
TO START
ENGINE
,_CAUTION:
Keep tine control in "OFF"
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.
• With engine level, refill to point of overflowing if necessary. Replace oil filler
plug.
• For cold weather operation you should
change oil for easier starting (See =OIL
VISCOSITY CHART" in the
Maintenance section of this manual).
• To change engine oil, see the
Maintenance section of this manual.
• 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).
Oil Level
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 emptiedbefore 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 section of this manual for addition- '
al 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
gasoline near an open flame.
• 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 temperatures (below 32°F), the carburetor fuel mixture may need to be
adjusted for best engine performance.
See "TO ADJUST CARBURETOR"
in the
Service and Adjustments section of this
manual.

_CAUTION:
Until you are accustomed to
handling yourtilier, start actual field use
with throttle in slow position (mid-way between "FAST" and "iDLE").
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 propedy in the soil being tilled. The proper setting of the wheels and depth stake is
through tdal and error and depends upon
the soil condition. (The harder or wetter
the ground, the slower the engine and fine
speed needed. Under these poor conditions, at fast speed the tiller will run and
jump over the ground).
A properly adjusted tiller will dig with little
effort from the operator.
first cuts at normal depth.
CULTIVATING
Cultivating is destroying the weeds
between rows to prevent 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".
• 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". A tiller will
also clear the soil of unwanted vegetation. The decomposition of this vegetable matter enriches the soil.
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 rou_gh
condition,
promoting
no further
growth of weeds and grass.
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 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
in the fall, remove vines and long grass
to prevent them from wrapping around
the tine shaft and slowing your tilling
operation.

has been preset at the factory and adjustment should not be necessary. However,
minor adjustments may be required to
compensate for differences in fuel, temperature, altitude or load. If the carburetor
does need adjustment, proceed as follows.

Throttle Stop
Immediatelyprepare 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 or
spark. Allow the engine to cool before
storing in any enclosure.
TILLER
• Clean entire tiller (See "CLEANING" in
the Maintenance section of this manual).
• Inspect and replace belts, if necessary
(See belt replacement instructions in the
Service and Adjustments 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, 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 in
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 storage. 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).
CYLINDER(S)
• Remove spark plug,
• Pour I 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.
