ADD GASOLINE
• Fill fuel tank to bottom of filler neck. Do not overfill.
Use fresh, clean, regular un lead ed 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 quan ti ties that can be used within 30 days to assure
fuel freshness.
CAUTION: Fill to within 1/2 inch of top
of fuel tank to prevent spills and to
allow for fuel expansion. If gasoline
is ac ci den tal ly 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 BELOW
32°F(0°C), USE FRESH, CLEAN WINTER GRADE GAS O LINE TO
HELP INSURE GOOD COLD WEATHER START ING.
CAUTION: Alcohol blended fuels (called gas o-
hol or using ethanol or methanol) can attract
moisture which leads to sep a ra tion and for ma-
tion 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 stor age 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 sea-
son. See Storage In struc tions for additional
information. Never use engine or carburetor
cleaner products in the fuel tank or permanent
damage may occur.
TO START ENGINE (See Fig. 14)
CAUTION: Keep drive control bar in
"DISENGAGED" position when start-
ing en gine.
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 prop er ly 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 com pres sion cycle (rope will
pull slightly harder at this point).
• Pull recoil starter handle quickly. Do not let 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.
OPERATION
• 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 (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
Adjustments section of this manual.
NOTE: If engine does not start, see troubleshooting
points.

TILLING HINTS (See Fig. 15)
• 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 veg-
e ta tion. The de com po si tion of this vegetable mat ter
enriches the soil. Depending on the climate (rain fall
and wind), it may be advisable to till the soil at the end
of the growing season to further condition the soil.
• 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. Sec ond, the tiller won't be pulling itself,
and you, toward the row next to it.
• Soil conditions are important for proper tilling. Tines will
not readily penetrate dry, hard soil which may con trib ute
to excessive bounce and difficult handling of your tiller.
Hard soil should be mois tened 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, re move vines and
long grass to prevent them from wrapping around the
tine shaft and slowing your tilling operation.

CAUTION: Until you are accustomed to
handling your tiller, start actual field use
with throttle in slow position (mid-way
between "FAST" and "IDLE").
