OPERATION
The operation of any tiller can result in foreign objects thrown into the eyes, which can result
in severe eye damage. Always wear safety glasses or eye shields before starting your tiller
and while tilling. We recommend a wide vision safety mask for over spectacles or standard
safety glasses.
HOW TO USEYOUR TILLER
Know how to operate all controls before adding fuel and oil
or attempting to start 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.

STARTING.
AROUND TOWN
•
•
•
Disconnect spark plug wire.
Drain fuel tank.
Transport in upright position to prevent oil leakage.
CAUTION: Alcohol blended fuels (called
gasohol or using ethanol or methanol) can at-
tract 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 carburetor are empty. Use fresh fuel next
season. SeeStorageInstructionsforadditional
information. Never use engine or carburetor
cleaner products in the fuel tank or permanent
damage may occur.
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.
FILL ENGINE WITH OIL (See Fig. 7)
•
•
With engine level, remove engine oil filler plug.
Fill engine with oil to point of overflowing. For approx-
imatecapacitysee“PRODUCTSPECIFICATIONS”on
page 3 of this manual.
•
•
Tilt tiller back on its wheels and then re-level.
With engine level, refill to point of overflowing if nec-
essary. 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.
TO START ENGINE (See Fig. 8)
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 will take extra pulls of the recoil starter to
move fuel from the tank to the engine.
•
•
•
•
•
•
Make sure spark plug wire is properly connected.
Move shift lever indicator to “N” (neutral) position.
Place throttle control in “FAST” position.
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 compression 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 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.

Fill fuel tank to bottom of filler neck. Do not overfill.
Use fresh, clean, regular unleaded 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 quantities that can be used within 30 days to assure
fuel freshness.
NOTE: A warm engine requires less choking to start.
•
•
Move throttle control to desired running position.

notreadilypenetratedry,hardsoilwhichmaycontribute
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.
NOTE: If engine does not start, see troubleshooting
points.
SPARK PLUG
•
•
You will find tilling much easier if you leave a row un-
tilled 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.

TILLING HINTS
FIG. 9
CAUTION: Until you are accustomed
to handling your tiller, start actual field
use with throttle in slow position.
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"-3".
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. Under these poor conditions, at fast speed the
tiller will run and jump over the ground).
•
Youwillprobablynotneedtousethedepthstake.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).
A properly adjusted tiller will dig with little effort from the
operator.
•
Tilling is digging into, turning over, and breaking up
packedsoilbeforeplanting. Loose,unpackedsoilhelps
root growth. Best tilling depth is 4"-6". A tiller will also

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.
