allow adults to op er ate the equipment without proper
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.
• Do not overload the machine capacity by attempting
to till too deep at too fast a rate.
• Never operate the machine at high speeds on slippery
surfaces. Look behind and use care when backing.
• Never allow bystanders near the unit.
• Use only attachments and accessories approved by
the manufacturer of the tiller.
• Never operate the tiller without good visibility or light.
• Be careful when tilling in hard ground. The tines may
catch in the ground and propel the tiller forward. If this
occurs, let go of the handlebars and do not restrain the
machine.
MAINTENANCE AND STORAGE
• Keep machine, attachments, and accessories in safe
work ing condition.
• Check shear pins, engine mounting bolts, and other
bolts at frequent intervals for proper tightness to be
sure the equip ment is in safe working condition.
• Never store the machine with fuel in the fuel tank inside
a building where ignition sources are present, such

OIL
LEVEL
FIG. 12
ADD GASOLINE
• Fill fuel tank to bottom of filler neck. 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.
AROUND THE YARD
• Release the depth stake pin. Move the depth stake
down to the top hole for transporting the tiller. Place
depth stake pin in hole of depth stake to lock in position. This prevents tines from scuffing the ground.
• Place shift lever indicator in “F” (forward) position for
transporting.
• Hold the drive control bar against the handle to start
tiller movement. Tines will not turn.
• Move throttle control to desired speed.
AROUND TOWN
• Disconnect spark plug wire.
• Drain fuel tank.
• Transport in upright position to prevent oil leakage.
BEFORE START ING 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.
CHECK ENGINE OIL LEVEL (See Fig. 12)
• The engine in your unit has been shipped, from the
factory, 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 SF-SJ.
• Reinstall engine oil cap and tighten.
• 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.
CAUTION: Fill to within 1/2 inch 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. 13)
CAUTION: Keep drive control bar 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.
9
OPERATION
• 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.
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 tem per a tures
(below 32°F), the carburetor fuel mixture may need to be
adjusted for best engine performance. See "TO AD JUST
CARBURETOR" in the Service and Adjustments section
of this manual.
NOTE: If engine does not start, see troubleshooting
points.
CHOKE CONTROL
CHOKE
RUN
• 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.

FIG. 14
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. 15).
RECOIL STARTER
HANDLE
FIG. 13
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. 14) 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. 15
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.

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. 16 and 17)
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”
in the Operation section of this manual.
