the controls quickly.
• Never allow children to operate the equipment. Never
allow adults to operate the equipment without proper
instruction.
• Keep the area of operation clear of all persons, par-
ticularly 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 (motor).
• Do not operate the equipment without wearing ade-
quate outer garments. Wear footwear that will improve
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
recommended by manufacturer).
OPERATION
• Do not put hands or feet near or under rotating parts.
• Exercise extreme caution when operating on or cross-
ing gravel drives, walks, or roads. Stay alert for hidden
hazards or traffic. Do not carry passengers.
• After striking a foreign object, stop the engine (motor),
remove the wire from the spark plug, thoroughlyinspect
the tiller for any damage, and repair the damage before
restarting and operating the tiller.
• Exercise caution to avoid slipping or falling.
• If the unit should start to vibrate abnormally, stop the
engine (motor) and check immediately for the cause.
Vibration is generally a warning of trouble.
• Stop the engine (motor) when leaving the operating
position.
• Take all possible precautions when leaving the machine
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 keepthe 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

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.
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 beto pointofoverflowing when engine
is level. For approximate capacity see "PRODUCT
SPECIFICATIONS" on page 3 of this manual. All oil
must meet A.EI. Service Classification SG-SL.
For cold weather operation you should change oil for
easier starting (See oil viscosity chart in the Mainte-
nance section of this manual).
To change engine oil, see the Maintenance section in
this manual.

FIG. 12
ADD GASOLINE
• 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.
CAUTION: Fill to within 112inch of top
offuel tankto prevent spills and to allow
for fuel expansion. If gasoline is ac-
cidentally 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
GASOLINE TO HELP INSURE GOOD COLD WEATHER
STARTING.
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. See Storage Instructions for additional
information. Never use engine or carburetor
cleaner products in the fuel tank or permanent
damage may occur.

OPERATION
TO START ENGINE (See Fig. 13) TILLING HINTS
I&CAUTION: Keep drive control bar in I
i
"DISENGAGED" position when start- I
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.
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
temperatures (below 32°F), the carburetor fuel mixture
may need to be adjusted for best engine performance.
See "TO ADJUST CARBURETOR" in the Service and
Adjustments section of this manual.
NOTE: If engine does not start, see troubleshooting
points.
CHOKE CONTROL
RECOIL STARTER HANDLE
FIG. 13
&CAUTION: Until you areaccustomedto
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 vegetation.
The decomposition 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.
• Soil conditions are important for proper tilling.Tines will
not readily penetrate dry, hard soilwhich may contribute
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.
• You will find tilling much easier if you leave a row un-
tilled 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. Second, 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.

OPERATION
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 Adjustments 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 transmission.
• 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).
FIG. 15
ADJUST WHEELS FOR CULTIVATING (See
Figs. 16 and 17)
• 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 (2.5 cm)
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 cultivat-
ing, 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. Toreceive
full value from the warranty, the operator must maintain tiller
as instructed in this manual.
Some adjustments will need to be made periodically to
properly maintain your tiller.
At least once a season, check to see if you should make
any of the adjustments described in the Service and Ad-
justments section of this manual.
• 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

NOTE: Although multi-viscosityoils (5W-30, 10W-30, etc.)
improve starting in cold weather, these multi-viscosity oils
will result in increased oil consumption when used above
32°F (0°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. 18 and 19)
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 container.
• Remove drain plug.
• 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

MUFFLER
Do not operate tiller without muffler. Do not tamper with
exhaust system. Damaged muftiers or spark arresters could
create a fire hazard. Inspect periodically and replace if
necessary. If your engine is equipped with a spark arrester
screen assembly, remove every 50 hours for cleaning and
inspection. Replace if damaged.
SPARK PLUG
Replace spark plugs at the beginning of each tilling sea-
son or after every 50 hours of use, whichever comes first.
Spark plug type and gap setting is shown in "PRODUCT
SPECIFICATIONS" on page 3 of this manual.
TRANSMISSION
Once a season, lubricate the right hand side gear case
grease fitting with oz. of EP #1 grease.
CLEANING
Do not clean your tiller when the engine and transmission
are hot. We do not recommend using pressurized water
(garden hose, etc.) to clean your unit unless the gasket
area around the transmission and the engine muffler, air
filter and carburetor are covered to keep water out. Water
in engine will shorten the useful life of your tiller.
• Clean engine, wheels, finish, etc. of all foreign mat-
ter.
• Keep finished surfaces and wheels free of all gasoline,
oil, etc.
• Protect painted surfaces with automotive type wax.

CAUTION: Disconnect spark plug wire from spark plug and place wire where it cannot come into I
contact with plug. I
TO ADJUST HANDLE HEIGHT (See Fig. 22)
Select handle height best suited for your tilling conditions.
Handle height will be different when tiller digs into soil.
• First loosen handle lock lever.
• Handle can be positioned at different settings between
"HIGH" and "LOW" positions.
• Retighten handle lock lever securely after adjusting.
TIRE CARE
I& CAUTION: When mounting tires, un- I
less beads are seated, overinflation can
cause an explosion.
• Maintain 20 PSI (1.4 kg/cm 2) of tire pressure. If tire
pressures are not equal, tiller will pull to one side.
• Keep tires free of gasoline or oil which can damage
rubber.

TINE REPLACEMENT
(See Figs. 24, 25 and 26)
I_ CAUTION: Tines are sharp. Wear I
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
FIG. 24
To maintain the superb tilling performance of this
machine 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
exceeds 3-1/2 inches (9 cm), they should be replaced
or straightened as necessary.
New tines should be assembled as shown in Fig.
28. Sharpened tine edges will rotate rearward from
above.

• 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.
ENGINE OIL
Drain oil (with engine warm) and replace with clean oil. (See
"ENGINE" in the Maintenance section of this manual).
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 ENGINE AND
EXHAUSTAREAS ARE STILLWARM.
