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
Adjust depth stake by removing the
hairpin clip and clevis pin. Change depth
stake to desired position. Replace the
clevis pin and hairpin clip.
•For normal tilling, set depth stake at the
second or third hole from the top.
WHEELS
Adjust wheels by removing the hairpin
clip and clevis pin. Change wheel
position. Replace the hairpin clip and

BEFORE STARTING ENGINE
IMPORTANT: Be very careful not to allow
dirt to enter the engine wher, 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
• Remove hangtao flrom engine.
• With engine lev,-, remove engine oil
filler plug.
• Fill engine with oil to point of overflow-
ing. For approximate capacity see
"PRODUCT SPECIFICATIONS".
•Tilt tiller back on its wheels and then re-
8level.

•With engine level, refill to point of
overflowing if necessary. Replace oil
filler plug.
•For cold weather operation you should
change oil for easier starting (See "OIL
VISCOSITY CHART" in the Mainte-
nance section of this manual).
• To change engine oil, see the Mainte-
nance section of this manual.
Oil Filler
Oil Level Plug
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.
_1= 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
empUed 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.
_i, CAUTION: Fill to within 1/2 inch of 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
_'_CAUTION: Keep tine 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.
•Make sure spark plug wire is properly
connected.
•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 compres-
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.
•When engine starts, slowly move
choke control to "RUN" position as
engine warms up.
NOTE: Awarm 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 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.

BREAKING IN YOUR TILLER
Break-in your belt(s), pulleys and tine
control before you actually begin tilling.
•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.
• Check tine operation and adjust if
necessary. See "TINE OPERATION
CHECK" in the Service and Adjust-
ments section of this manual.
TILLING HINTS
_, CAUTION: Until you are accustomed
to handling your tiller, start actual field use
with throttle in slow position.
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. Under these 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.
• Tilling is digging into, turning over, and
breaking up packed soil before
planting. Loose, unpacked soil helps
root growth. Best tilling depth is 4"-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 till the
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 "baU-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.
• 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.
CULTIVATING
Cultivating is destroying the weeds be-
tween 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"-3".
• 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 wil! allow tines to uproot
weeds and leave the ground in rough
condition, promoting no further growth
of weeds and grass.

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, the operator
must maintain 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 belts for wear. A
new spark plug and clean air filter
assure proper air-fuel mixture and help
your engine run better and last longer.
BEFORE EACH USE
• Check engine oil level.
• Check tine operation.
•Check for loose fasteners.

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
)ossible engine damage from running low
on oil.
Change the oil after every 50 hours of
operation or at least once a year if the
tiller is not used for 50 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

Maintenance, repair, or replacement of
the emission control devices and sys-
tems, which are being done atthe
customers expense, may be performed
by any non-road engine repair establish-
ment or individual. Warranty repairs must
be performed by an authorized engine
manufacturer's service outlet.
TO ADJUST CARBURETOR
The carburetor has ahigh speed fixed jet
and has been preset at the factory and
adjustment should not be necessary.
However, minor adjustments may be
required to compensate for differences in
fuel, temperature, altitude or load. If the
carburetor does need adjustment,
proceed as follows.
IDLE RPM ADJUSTMENT
•To adjust idle RPM, rotate throttle
linkage counterclockwise and hold
against stop while adjusting idle speed
adjusting screw to obtain 1750 RPM.
Release throttle linkage.
ACCELERATION TEST
•Move throttle control lever from
"SLOW" to "FAST' position. If engine
hesitates or dies, turn idle needle valve
out (counterclockwise) 1/8 turn.
Repeat test and continue to adjust, if
necessary, until engine accelerates
smoothly.
High speed stop is factory adjusted. Do
not adjust or damage may result.
IMPORTANT: Never tamper with the
engine governor, which is factory set for
proper engine speed, overspeeding the
engine above the factory high speed
setting can be dangerous. If you think the
engine-governed high speed needs
adjusting, contact your nearest authorized
service center/department, which has the
proper equipment and experience to
make any necessary adjustments.

Immediately prepare your tiller for storage
at the end of the season or if the unit will
not be used for 30 days or more.
_1, CAUTION: Never store the tiller with
gasoline in the tank inside a building
where fumes may reach an open flame or
spark. Allow the engine to cool before
storing in any enclosure.
TILLER
•Clean entire tiller (See "CLEANING" in
the Maintenance section of this
manual).
• Inspect and replace belts, if necessary
(See belt replacement instructions in
the Service and Adjustments section of
this manual).
• Lubricate as shown in the Maintenance
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 lightly before painting.
ENGINE
FUELSYSTEM
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.
• 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 storage. Add
stabilizer to gasoline in fuel tank or
storage container. Always follow the mix
ratio found on stabilizer container. Run
engine at !east 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
Maintenance section of this manual).
CYLINDER
• Remove spark plug.
• Pour 1 ounce (29 ml) of oil through
spark plug hole into cylinder.
• Pull starter handle slowly several times
to distribute oil.
• Replace with new spark plug.
OTHER
• Do not store gasoline from one season
to another.
• 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 protec-
tive 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.
