Safe Operation Practices for Walk-Behind Powered Ro ta ry Tillers

TRAINING

• Read the Manual care ful ly. Be thor ough ly fa mil iar with
the controls and the proper use of the equip ment.
Know how to stop the unit and disengage 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).

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
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.

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. 13)

• 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 SG-SL.

• 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.

OUTER SIDE SHIELDS (See Fig. 12)

The back edges of the outer side shields are slotted so
that the shields can be raised for deep tilling and low ered
for shal low tilling to protect small plants from being buried.
Loosen nut “A” in slot and nut “B”. Move shield to desired
position (both sides). Retighten nuts.

OPERATION

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.

• 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.

TILLING HINTS (See Fig. 15)

CAUTION: Until you are accustomed to
handling your tiller, start actual field use
with throttle in slow position (mid-way
between “FAST” and “IDLE”).

TO START ENGINE (See Fig. 14)

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.

• 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.

• 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.

• 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.

10

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. 15

CULTIVATING (See Fig. 16)

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. 16).

• Do not lean on handle, this takes weight off the wheels,
reduces traction, and may cause the tiller to skip over
the ground.

• Always lower the drag stake when using the for ward

rotating tine drive.

ADJUST WHEELS FOR CULTIVATING
(See Figs. 17 and 18)

• Place blocks under right hand side of tiller and remove
hairpin clip and clevis pin from right hand wheel.

• Move wheel outward approximately 1 inch until hole in
inner wheel hub lines up with inner hole in axle.

• Replace clevis pin and hairpin clip on inside of wheel
and remove blocks.

• Repeat preceding steps on left hand side.

NOTE: In extremely rough conditions and while
cultivating, the wheels should be moved outward on the
axle for increased stability.

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.

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. 19 and 20)

• 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.

TINE REPLACEMENT
(See Figs. 27, 28 and 29)

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

FIG. 27

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 inches they should be replaced or straight ened
as necessary.

• For tines that are slightly worn, the bolt ed tine and hub
assemblies can be switched between sides to continue
till ing in the same tilling mode if tilling in a different mode
is desired then the bolt ed tine and hub assemblies
should be switched back to their original side so that
the tine edge with the least wear will be used.

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.

CAUTION: 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 enclosure.

TILLER

• Clean entire tiller (See “CLEANING” in the Maintenance
section of this manual).

• Inspect and replace belts, if nec es sary (See belt re­ place ment in struc tions 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

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 pro tec tive cover that
does not retain moisture. Do not use plastic. Plastic
cannot breathe which allows con den sa tion to form and
will cause your unit to rust.

IMPORTANT: NEVER COVER TILLER WHILE ENGINE AND
EXHAUST AREAS ARE STILL WARM.

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.

• 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.

• 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.
