TINES
• Release tine control to stop movement.
ENGINE
0 Move throttle control to “STOP” position.
® Never use choke to stop engine.
FIG. 5
TINE OPERATION (See Fig. 5)
• Squeeze tine control to handle.
TILLING
The speed and depth of tilling is regulated by the position
of the depth stake and wheel height.
The depth stake should always be below the wheels for
digging. It serves as a brake to slow the tiller’s forward
motion to enable the tines to penetrate the ground. Also,
the more the depth stake is lowered into the ground the
deeper the tines will dig.
DEPTH STAKE (See Fig. 6)
Adjust depth stake by removing the hairpin clip and clevis
pin. Change depth stake to desired position. Replace the
clevis pin and hairpin clip.
0 For normal tilling, set depth stake at the second orthird
hole from the top.
WHEELS (See Fig. 6)
Adjust wheels by removing the hairpin clip and clevis pin.
Change wheel position. Replace the hairpin clip and clevis
pin.
• For normal tilling, set wheels at the second or third hole
from the top.

TRANSPORTING YOUR TILLER
A CAUTION: Before Sifting or transport¬
ing, allow tiller engine and muffler to
cool. Disconnect spark plug wire. Drain
gasoline from fuel tank.
AROUND THE YARD
• Tip depth stake forward until it is held by the stake
spring.
• Push tiller handles down, raising tines off the ground.
» Push or pull tiller to desired location.
AROUND TOWN
9 Disconnect spark plug wire.
• Drain fuel tank.
9 Transport in upright position to prevent oil leakage.
BEFORE STARTING ENGINE
IMPORTANT: BE VERY CAREFUL NOTTO ALLOW DIRT
TO ENTER THE ENGINE WHEN CHECKING OR ADDING
OIL OR FUEL. USE CLEAN OIL AND FUEL AND STORE
IN APPROVED, CLEAN, COVERED CONTAINERS. USE
CLEAN FILL FUNNELS.
FILL ENGINE WITH OIL {See Fig. 7)
• With engine level, remove engine oil filler plug.
® Fill engine with oil to point of overflowing. For approxi¬
mate capacity see “PRODUCT SPECIFICATIONS” on
page 3 of this manual.
0 Tilt tiller back on its wheels and then re-level.
a With engine level, refill to point of overflowing if neces¬
sary. Replace oil filler plug.
8 For cold weather operation you should change oil for
easier starting {See “OIL VISCOSITY CHART” in the
Customer Responsibilities section of this manual).
9 To change engine oil, see the Customer Responsibili¬
ties section of this manual.
9 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 TEMPERATURES
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 products in the fuel tank or permanent
damage may occur.
A
CAUTION: Fill to within 1/2 Inch of top j
of fuel tank to prevent spills and t© !
allow for fuel expansion. If gasoline Is j
accidentally spilled, move machine i
away from area of spill. Avoid creating I
any source of ignition until gasoline j
vapors have disappeared, j
Do not overfill. Wipe off any spilled oil l
or fuel. Do not store, spill or use gaso- j
line near an open flame. * \
TO START ENGINE (See Fig. 8)
\A
CAUTION: Keep tine control in “OFF” j
position when starting engine, 1
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.
• Place throttle control in “FAST’ position.
8 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
puli slightly harder at this point).
8 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.
• When engine starts, slowly move choke control to
“RUN” position as engine warms up.
NOTE: A warm engine requires less choking to start.
8 Move throttle control to desired running position.
9 Allow engine to warm up for a few minutes before
engaging tines.
NOTE: If at a high altitude (3000 feet) or in cold tempera¬
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.

FIG. 8
BREAKING IN YOUR TILLER
Break-in your belt(s), pulleys and tine control before you
actually begin tilling.
9 Start engine, tip tines off ground by pressing handles
down and engage tine control to start tine rotation.
Allow tines to rotate for five minutes.
8 Check tine operation and adjust if necessary. See
“TINE OPERATION CHECK” in the Service and Ad¬
justments section of this manual.
TILLING HINTS
I A, CAUTION: Until you are accustomed to
A jk handling your tiller, start actual field j
I Sk with throttle in slow position (mid-
I flwLJP way between “FAST” and “IDLE”).
To help tiller move forward, lift up the handles slightly (thus
lifting depth stake out of ground). To slow down the tiller,
press down on handles.
If you are straining or tiller is shaking, the wheels and depth
stake are not set properly in the soil being tilled. The proper
setting of the wheels and depth stake is through trial and
error and depends upon the soil condition. (The harder or
wetter the ground, the slower the engine and tine speed
needed. Underthese poor conditions, at fast speed the tiller
will run and jump over the ground).
A properly adjusted tiller will dig with little effort from the
operator.
9 Tilling is digging into, turning over, and breaking up
packed soil before planting. Loose, unpacked soil
helps root growth. Best tilling depth is4"-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.
* Soil conditions are importantfor proper tilling. 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 “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.
e You will find tilling much easier if you leave a row
untilled between passes. Then go back between tilled
rows. (See Fig. 9) 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.
Set depth stake and wheel height for shallow tilling
when working extremely hard soil or sod. Then work
across the first cuts at normal depth.
FIG. 9
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"-3" (2.5-7.S cm).
9 You will probably not need to use the depth stake.
Begin by tipping the depth stake forward until it is held
by the stake spring.
® 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. 10).
FIG. 10

CUSTOMER
1 * Change more often when operating under a heavy load or in high ambient temperatures.
2 - Service more often when operating in dirty or dusty conditions.
GENERAL RECOMMENDATIONS
The warranty on this tiller does not cover items that have
been subjected to operator abuse or negligence. To
receive full value from the warranty, operator must main¬
tain tiller as instructed in this manual.
Some adjustments will need to be made periodically to
properly maintain your tiller.
All adjustments in the Service and Adjustments section of
this manual should be checked at least once each
season.
* Once a year you should replace the spark plug, clean
or replace air filter, and check tines and belt for wear.
A new spark plug and clean air filter assure proper air-
fuel mixture and help your engine run better and last

TEMPERATURE RANGE ANTICIPATED BEFORE NEXT OIL CHANGE
FIG. 11
NOTE: Although multi-viscosity oils (5W-30,10W-30, etc.)
improve starting in cold weather, these multi-viscosity oils
will result in increased oil consumption when used above
32°F (0°C). Check your engine oil level more frequently to
avoid possible engine damage from running low on oil.
Change the oii after every 25 hours of operation or at least
once a year if the tiller is not used for 25 hours in one year.
Check the crankcase oil level before starting the engine
and after each five (5) hours of continuous use. Add SAE
30 motor oil or equivalent. Tighten oil filler plug securely
each time you check the oil level.

section of this manual).
• Lubricate as shown in the Customer Responsibilities
section of this manual.
• Be sure that all nuts, bolts and screws are securely
fastened, inspect moving parts for damage, breakage
and wear. Replace if necessary.
• Touch up all rusted or chipped paint surfaces; sand

FUEL SYSTEM
IMPORTANT: IT IS IMPORTANT TO PREVENT GUM
DEPOSITS FROM FORMING IN ESSENTIAL FUEL
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.
s 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.
ENGINE OIL
Drain oil (with engine warm) and replace with clean oil.
(See “ENGINE” in the Customer Responsibilities section of
this manual).
CYLINDER
8 Remove spark plug.
• Pour 1 ounce (29 ml) of oil through spark plug hole into
cylinder.
8 Pull starter handle slowly several times to distribute oil.
• Replace with new spark plug.
8 Do not store gasoline from one season to another.
8 Replace your gasoline can if your can starts to rust.
Rust and/or dirt in your gasoline will cause problems.
• If possible, store your unit indoors and cover it to give
protection from dust and dirt.
® Cover your unit with a suitable protective cover that
does not retain moisture. Do not use plastic. Plastic
cannot breathe which allows condensation to form and
will cause your unit to rust.
IMPORTANT: NEVER COVER TILLER WHILE ENGINE
AND EXHAUST AREAS ARE STILL WARM.
