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  
Spark Plug  
Wipe off any spilled oil or fuel. Do not  
store, spill or use gasoline near an  
open flame.

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.

allow tines to uproot weeds and leave the ground in  
rough condition, promoting no further growth of weeds  
and grass (See Fig. 16).

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.
