WARNING: This unit is equipped with an internal com-
bustion engine and should not be used on or near any
unimprovedforest-covered,brush-coveredorgrasscovered
land unless the engine's exhaust system is equipped with
a spark arrester meeting applicable local laws (if any). If a
spark arrester is used, it should be maintained in effective
working order by the operator.
CONGRATULATIONS on your purchase of a new tiller. It
has been designed, engineered and manufactured to give
you the best possible dependability and performance.
Should you experience any problems you cannot easily
remedy, please contact your nearest authorized service
center. We have competent, well-trained technicians and
the proper tools to service or repair this unit.
In the state of California, a spark arrester is required by law
(Section 4442 of the California Public Resources Code).
Other states may have similar laws. Federal laws apply
on federal lands. See your authorized service center/
DEPARTMENT for spark arrester.
Please read and retain this manual. The instructions will
enable you to assemble and maintain your tiller properly.
Always observe the “SAFETY RULES”.

OPERATION
ADD GASOLINE
until engine starts.
5. When engine starts, slowly move choke control to
“RUN” position as engine warms up.
•
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.
NOTE: A warm engine requires less choking to start.
6. Move throttle control to desired running position.
7. Allow engine to warm up for a few minutes before
engaging tines.
NOTE: If at a high altitude (3000 feet) or in cold tem-
peratures (below 32°F), the carburetor fuel mixture may
need to be adjusted for best engine performance. See
“TO ADJUST CARBURETOR” in the Service and Adjust-
ments section of this manual.
CAUTION: Fill to within 1/2 inch of top
offueltanktopreventspillsandtoallow
for fuel expansion. If gasoline is ac-
cidentally spilled, move machine away
from area of spill. Avoid creating any
sourceofignitionuntilgasolinevapors
have disappeared.
NOTE: If engine does not start, see troubleshooting

Wipe off any spilled oil or fuel. Do not
store, spill or use gasoline near an
open flame.
IMPORTANT: WHEN OPERATING IN TEMPERATURES

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. SeeStorageInstructionsforadditional
information. Never use engine or carburetor
cleaner products in the fuel tank or permanent
damage may occur.

Tilling is digging into, turning over, and breaking up
packedsoilbeforeplanting.Loose,unpackedsoilhelps
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.
TO START ENGINE
CAUTION: Keep tine control in “OFF” position
when starting 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.
1. Make sure spark plug wire is properly connected.
2. Place throttle control in “FAST” position.
3. 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 compression cycle (rope will
pull slightly harder at this point).
4. Pull recoil starter handle quickly. Do not let starter
handle snap back against starter. Repeat if neces-
sary.
NOTE: If engine fires but does not start, move choke
control to half choke position. Pull recoil starter handle
•
•
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.
Soilconditionsareimportantforpropertilling.Tineswill
notreadilypenetratedry,hardsoilwhichmaycontribute
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.

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

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

the tine edge with the least wear will be used.
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.
