the controls quickly.

• Never allow children to operate the equipment. Never
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).

• 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
as hot water and space heaters, clothes dryers, and
the like. Allow the engine to cool before storing in any
enclosure.

• Always refer to the operator’s guide instructions for
im por tant details if the tiller is to be stored for an ex­tended period.

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.

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.

OIL
FILL

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.

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 tine control in “OFF”
position when starting engine.

OPERATION

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 to 1/4 turn to OPEN position.

• Push stop switch to “ON” 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 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 mix ture may need to be
adjusted for best engine per for mance. See “TO AD JUST
CARBURETOR” in the Service and Ad just ments section
of this manual.

NOTE: If engine does not start, see troubleshooting
points.

FIG. 13

TILLING HINTS

CAUTION: Until you are accustomed
to handling your tiller, start actual field
use with throttle in slow position.

• 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.

• 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.

• 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

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.

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).

• 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"(10-15cm). 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.

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
air-fuel mixture and help your engine run better and
last longer.

BEFORE EACH USE

• Check engine oil level.

• Check tine operation.

• Check for loose fasteners.
