OPERATION

TILLING HINTS (See Fig. 15)

CAUTION: Until you are accustomed to

handling 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

root growth. Best tilling depth is 4" to 6" (10-15 cm).

A tiller will also clear the soil of unwanted vege 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.

CHOKE CONTROL

RECOIL STARTER

HANDLE

• 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.
• Allow engine to warm up for a few minutes before

engaging tines.

NOTE: If at a high altitude (3000 feet) or in cold tem per a tures

(below 32°F), the carburetor fuel mixture may need to be

adjusted for best engine performance. See "TO AD JUST

CARBURETOR" in the Service and Adjustments section

of this manual.
NOTE: If engine does not start, see troubleshooting

points.

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

BELOW32°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 at-

tract 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.
• Turn fuel shut-off valve 1/4 turn to open position.
• Move choke control to 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.
