instruction.
• Keep the area of operation clear of all persons, par tic u lar ly small children, and pets.
PREPARATION
• Thoroughly inspect the area where the equipment is
to be used and remove all foreign objects.
• Disengage all clutches and shift into neutral before
starting the engine (mo tor).
• Do not operate the equipment with out wearing ad e quate
outer gar ments. Wear footwear that will im prove footing
on slippery surfaces.
• Handle fuel with care; it is highly flammable.
• Use an approved fuel container.
• Never add fuel to a running engine or hot engine.
• Fill fuel tank outdoors with extreme care. Never fill fuel
tank indoors.
• Replace gasoline cap securely and clean up spilled
fuel before restarting.
• Use extension cords and receptacles as specified by
the manufacturer for all units with electric drive motors
or electric starting motors.
• Never attempt to make any adjustments while the
engine (motor) is running (except where specifically
rec om mend ed by manufacturer).
OPERATION
• Do not put hands or feet near or under rotating parts.
• Exercise extreme caution when op er at ing on or cross ing gravel drives, walks, or roads. Stay alert for hidden
hazards or traffic. Do not carry pas sen gers.
• After striking a foreign object, stop the engine (motor),
remove the wire from the spark plug, thoroughly in spect
the tiller for any damage, and repair the damage before
restarting and op er at ing the tiller.
• Exercise caution to avoid slipping or falling.
• If the unit should start to vibrate ab nor mal ly, stop the
engine (motor) and check immediately for the cause.
Vi bra tion is generally a warning of trouble.
• Stop the engine (motor) when leaving the operating
position.
• Take all possible precautions when leav ing the ma chine
unattended. Disengage the tines, shift into neutral, and
stop the engine.
• Before cleaning, repairing, or inspecting, shut off the
engine and make certain all moving parts have stopped.
Disconnect the spark plug wire, and keep the wire away
from the plug to prevent accidental starting. Disconnect
the cord on electric motors.
• Do not run the engine indoors; exhaust fumes are
dangerous.
• Never operate the tiller without proper guards, plates,
or other safety protective devices in place.
• Keep children and pets away.

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
AP PROVED, CLEAN, COVERED CONTAINERS. USE CLEAN
FILL FUNNELS.
CHECK ENGINE OIL LEVEL (See Fig.11)
• The engine in your unit has been shipped, from the fac-
tory, already filled with SAE 30 summer weight oil.
• With engine level, clean area around oil filler plug and
remove plug.
• Engine oil should be to point of overflowing when engine
is level. For ap proxi mate capacity see “PROD UCT
SPEC I FI CA TIONS” on page 3 of this manual. All oil
must meet A.P.I. Service Classification SG-SL.
• For cold weather operation you should change oil for
easier starting (See oil viscosity chart in the Maintenance sec tion of this manual).
• To change engine oil, see the Maintenance section in
this manual.

ADD GASOLINE
• Fill to within 1/2" of top of fuel tank to prevent spills and
to allow for fuel expansion. Do not overfill. Use fresh,
clean, regular un lead ed 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 quan ti ties that
can be used within 30 days to assure fuel freshness.
CAUTION: Fill to within 1/2" of top of
fuel tank to prevent spills and to allow
for fuel expansion. If gasoline is ac ci den tal ly spilled, move machine away
from area of spill. Avoid creating any
source of ignition until gasoline vapors
have disappeared.
Wipe off any spilled oil or fuel. Do not
store, spill or use gasoline near an
open flame.
IMPORTANT: WHEN OPERATING IN TEMPERATURES
BELOW32°F(0°C), USE FRESH, CLEAN WINTER GRADE
GAS O LINE TO HELP INSURE GOOD COLD WEATHER
START ING.
CAUTION: Alcohol blended fuels (called gas o hol or using ethanol or methanol) can attract
moisture which leads to sep a ra tion and for ma tion 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 stor age 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
sea son. See Storage In struc tions for additional
information. Never use engine or carburetor
cleaner products in the fuel tank or permanent
damage may occur.
TO START ENGINE (See Fig. 12)
CAUTION: Keep tine control in “DISENGAGED” position when start ing en gine.
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 prop er ly 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 com pres sion 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.

• Soil conditions are important for proper tilling. Tines will
not readily penetrate dry, hard soil which may con trib ute
to excessive bounce and difficult handling of your tiller.
Hard soil should be mois tened 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, re move vines and
long grass to prevent them from wrapping around the
tine shaft and slowing your tilling operation.
• 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.
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). 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. 14).
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 vege ta tion.
The de com po si tion of this vegetable mat ter enriches
the soil. Depending on the climate (rain fall and wind),
it may be advisable to till the soil at the end of the
growing season to further condition the soil.
• You will find tilling much easier if you leave a row
untilled between passes. Then go back between tilled
rows. (See Fig. 13) There are two reasons for doing
this. First, wide turns are much easier to negotiate than
about-faces. Sec ond, the tiller won’t be pulling itself,
and you, toward the row next to it.
Fig. 14
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 Ad just ments 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 trans mis sion.
• If shear pin(s) break, replace only with those shown in
the Repair Parts section of this manual.

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 main tain
tiller as instructed in this manual.
Some adjustments will need to be made periodically to
properly maintain your tiller.
All 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 airfuel mixture and help your engine run better and last
longer.
BEFORE EACH USE
• Check engine oil level.

NOTE: Although multi-viscosity oils (5W-30, 10W-30, etc.)
improve starting in cold weather, these multi-viscosity oils
will result in increased oil consumption when used above
40°F (4°C). Check your engine oil level more frequently to
avoid possible engine damage from running low on oil.
Change the oil after every 25 hours of operation or at
least once a year if the tiller is not used for 25 hours in
one year.
Check the crankcase oil level before starting the engine
and after each five (5) hours of continuous use. Add SAE
30 motor oil or equivalent. Tighten oil filler plug securely
each time you check the oil level.
TO CHANGE ENGINE OIL (See Figs. 15 and 16)
Determine temperature range expected before oil change.
All oil must meet API service classification SG-SL.
• Be sure tiller is on level surface.
• Oil will drain more freely when warm.
• Use a funnel to prevent oil spill on tiller, and catch oil
in a suitable con tain er.
• Remove drain plug. For easier removal of plug use
7/16 12 Pt. socket with extension.)
• Tip tiller forward to drain oil.
• After oil has drained completely, replace oil drain plug
and tighten securely.
• Remove oil filler plug. Be careful not to allow dirt to
enter the engine.
• Refill engine with oil. See “CHECK ENGINE OIL LEVEL”

TINE REPLACEMENT (See Figs. 23, 24 and 25)
CAUTION: Tines are sharp. Wear
gloves or other protection when han dling tines.
A badly worn tine causes your tiller to work harder and dig
more shallow. Most important, worn tines cannot chop and
shred organic matter as effectively nor bury it as deeply as
good tines. A tine this worn needs to be replaced.
NEW TINE

WORN TINE
• To maintain the superb tilling performance of this
ma chine the tines should be checked for sharpness,
wear, and bending, particularly the tines which are
next to the transmission. If the gap between the tines
ex ceeds 3-1/2" they should be replaced or straight ened
as necessary.
• New tines should be assembled as shown in Fig.

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.
WARNING: Never store the tiller with
gasoline in the tank inside a build ing
where fumes may reach an open flame
or spark. Allow the engine to cool before
storing in any en clo sure.
TILLER
• Clean entire tiller (See “CLEANING” in the Maintenance
section of this manual).
• Inspect and replace belts, if necessary (See belt re place ment instructions in the Service and Ad just ments
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, break age
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 ES SEN TIAL FUEL SYS TEM PARTS SUCH
AS THE CAR BU RE TOR, FUEL FILTER, FUEL HOSE, OR TANK
DURING STOR AGE. ALSO, EXPERIENCE INDICATES THAT
AL CO HOL BLENDED FUELS (CALLED GASOHOL OR USING
ETHA NOL OR METHA NOL) CAN ATTRACT MOIS TURE WHICH
LEADS TO SEPA RA TION AND FORMATION OF ACIDS DUR ING
STOR AGE. ACIDIC GAS CAN DAMAGE THE FUEL SYSTEM
OF AN ENGINE WHILE IN STOR AGE.
• Empty the fuel tank by starting 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 stablizer 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 stablizer container.
Run engine at least 10 minutes after adding stablizer to
allow the stabilizer to reach the carburetor. Do not empty
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 Maintenance section of this man ual).
CYLINDER(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 EN GINE AND
EX HAUST AREAS ARE STILL WARM.
