OPERATION
TO START ENGINE (See Fig. 13)
A
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.
« 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).
* Pull recoil starter handle quickly. Do not lei starter
handle snap back against starter. Repeat If necessary.
» 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.
» Ailow engine to warm up for a few minutes before
engaging tines.
NOTE: If at a high altitude (above 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 Adjust
ments section of this manual.
NOTE: if engine does not start, see troubleshooting points.
CAUTION: Keep drive control bar in
“DISENGAGED*’ position when start
ing engine.
TILLING HINTS
CAUTION: Until you are accustomed to
A
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 mat
ter enriches the soil. Depending on the climate (rainfall
and wind). It may be advisable to tiii the soil at the end
of the growing season to further condition the soil.
Soil conditions are important for propertiliing. Tines will
not readily penetrate dry, hard soil which may contrib
ute to excessive bounce and difficult handling of your
tiller. Hard soil should be moistened before tilling:
however, extremely wet soil will “bal!-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 yourtiliing operation.
For easier handling of your tiller, leave about 8 inches
(20 cm) of untilled soil between the first and second
tilling passes. The third pass will be between the first
and second (See Fig. 14).
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.
handling your tiller, start actual field
use with throttle in slow position (mid
way between “FAST” and “IDLE”).
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).
jfrthertiiler is unusuaity oveiloaded or'iarrtiTiedrthe 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.

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
allow tines to uproot weeds and leave the ground in
rough condition, promoting no further growth of weeds
and grass (See Fig. 15).,

TO ADJUST CARBURETOR (See Fig. 30)
The carburetor has a high speed jet and has been preset at
the factory and adjustment should not be necessary. How
ever, minor adjustments may be required to compensate
for differences In fuel, temperature, altitude or load. If the
carburetor does need adjustment, proceed as follows.
in general, turning the idle needle valve in (clockwise)
decreases the supply of fuel to the engine giving a leaner
fuei/air mixture. Turning the needle valve out (counter
clockwise) Increases the supply of fuel to the engine giving
a richer fuei/air mixture.
IMPORTANT: DAMAGE TO THE NEEDLES AND THE
SEATS IN CARBURETOR MAY RESULT IF SCREWS ARE
TURNED IN TOO TIGHT.
PRELIMINARY SETTING
» Air cleaner assembly must be assembled to the carbu
retor when making carburetor adjustments.
« Be sure the throttle control cable Is adjusted properly
(see above).
® With engine off, turn idle needle valve in (clockwise)
closing it finger tight and then turn valve out (counter
clockwise) 1-1/2 turns.
FINAL SETTING
» Start engine and allow to warm for five minutes. Make,
final adjustments with engine running at idle and drive
control bar in “DISENGAGED" position.

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.
“ Drain the fuel tank.
Start 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 damage may occur.
» Use fresh fuel next season.
NOTE: Fuel stabilizer is an acceptable alternative in
minimizing the formation of fuel gum deposits during stor
age. Add stabilizer to gasoline in fuel tank or storage
container. Always follow the mix ratio found on stabilizer
container. Run engine at least 10 minutes after adding
stabilizer to allow the stabilizer to reach the carburetor. Do
not drain the gas tank and carburetor if using fuel stabilizer.
