and store in approved, clean, covered containers, use clean fill funnels.
CHECK ENGINE OIL LEVEL
The engine in your unit has been shipped, from the factory, already filled
with SAE 30 summer weight oil.
1. With engine level, clean area around oil filler plug and remove plug.
2. Engine oil should be to point of ovedowing when engine is level.
For approximate capacity see "PROD-
UCT SPECIFICATIONS" on page 4 of this manual. All oil must meet A.P.I,
Service Classification SF, SG or SH.
3. Reinstall engine oil cap and tighten
10
For cold weather operation you should
change oil for easier starting (See oil viscosity chart in the Maintenance section of this manual).
To change engine oil, see the Mainte- nance section in this manual.
Oil Fill
ADD GASOLINE
Fill fuel tank. Use fresh, clean, regular
unleaded gasoline. (Use of leaded gasoline will increase carbon and lead oxide deposits and reduce valve life.)
IMPORTANT: When operating in tem-
peratures below 32°F(0°C), use fresh,
clean, winter grade gasoline to help insure good cold weather starting.
_WARNING: 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. 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 section of this
manual for additional information. Never use engine or carburetor cleaner prod-
ucts in the fuel tank or permanent damage may occur.
ACAUTION: Fill to within 1/2 inchof top of fuel tank to prevent spills and to allow
for fuel expansion. If gasoline is acciden- tally spilled, move machine away from area of spill. Avoid creating any source of
ignition until gasoline vapors have disappeared.
Do not overfill. Wipe off any spilled oil or
fuel. Do not store, spill or use gasoline near an open flame.
TO START ENGINE ACAUTION: Keep fine 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 propedy connected.
2. Move shift lever indicator to "N" (neutral) position.
3. Place throttlecontrol in "FAST" position.
4. Turn fuel shut-off valve 1/4 turn to open position.
5. Push stop switchto "ON" position.
6. Move choke control to "CHOKE" position.
7. 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 (rape will pull slightly harder at
this point).
8. Pull recoil starter handle quickly. Do not let starter handle snap back against starter.
NOTE: If engine fires but does not start, move choke controlto half choke position.
Pull recoil starter handle until engine starts.
9. When engine starts, slowly move choke control to "RUN" position as
engine warms up.
NOTE: A warm engine requires less choking to start.
1O.Move throttle control to desired
running position.
11.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.

TILLING HINTS _anCAUTION; Until you are accustomed to
dling 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
rootgrowth. Best tilling depth is 4" to 6".
A tiller will also clear the soil of un- wanted vegetation. The decomposition
of this vegetable matter enriches the soil. Depending on the climate (rainfall
and wind), it may be advisable to tillthe 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 soil which 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 untilled between passes.
Then go back between tilled
rows.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.
-_>
CULTIVATING Cultivating is destroying the weeds
between rows to prevent 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.
Do not lean on handle, this takes weight off the wheels, reduces traction, and may cause the tiUerto skip over the
ground.
Always lower the drag stake when
using the forward rotating tine drive.

TINE SHEAR PINS The tine assemblies on your tiller are
secured to the tine shaft with shear pins (See "TINE REPLACEMENT" in the
Sewice 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.
