Classification SF, SG or SH.
® For cold weather operation you should
change oil for easier starting (See oil
viscosity chart in the Customer
Responsibilities section of this manual).
® To change engine oil, see the Customer
Responsibilities section in this manual.
TO TR ANS POR T
A.CAUTION: Before lifting or transport
ing, allow tiller engine and muffler to cool.
Disconnect spark plug wire. Drain gaso
line from fuel tank.
AROUND THE YARD
® Release the depth stake pin. Move the
depth stake down to the top hole for
transporting the tiller. Place depth stake
pin in hole of depth stake to lock in posi
tion. This prevents tines from scuffing
tfie ground.

will not turn.
a Move throttle control to desired speed.
AROUND TOWN
® Disconnect spark plug wire.
® Drain fuel tank.
® Trarrsport in upright position to prevent
or! leakage.
BEFOR E S TART IN G E NGI NE
IMPORTANT: Be very careful not to allow
dirt to enter the engine when checking or
adding oil or fuel. Use clean oil and fuel
and store in approved, clean, covered con
tainers. use clean fill funnels.
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 tempera
tures below 32°F (0“C), use fresh, clean,
winter grade gasoline to help insure good
cold weather starting.
WARNING: Experience indicates that alco
hol 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 dam
age the fuel system of an engine while in
storage. To avoid engine problems, the
foel 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 pext season. See
Storage section of this manual for addition
al information. Never use engine or carbu
retor cleaner products in the fuel tank or
permanent damage may occur.

Page 11
^CAUTION: Fill to within 1/2 inch of top
of fuel tank to prevent spills and to allow
for fuel expansion, if gasoline is accident
tally spilled, move machine away from
area of spill. Avoid creating any source of
ignition until gasoline vapors have disap
peared.
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 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 and access cover is com
pletely closed to create proper seal.
« Move shift lever Indicator to “N” (neutral)
position.
a Place throttle control in “FAST” position.
® Turn fuel shut-off valve to “ON” position.
® Push stop switch to “ON” position.
» Move choke control to full “CHOKE”
position. Grasp recoil starter handle with
one hand and grasp tiller handle with
other hand. Pul! rope out slowly until
engine reaches start of compression
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.

o Allow engine to warm up for a few min
utes before engaging tines,
NOTE: If at a high altitude (3000 feet) or
in cold temperatures (below 32°F), the car
buretor 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 trou
bleshooting points.
TILLING HINTS
AcAUTION: Until you are accustomed ti
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". A tiller will
also clear the soil of unwanted vegeta
tion. The decomposition of this veg
etable 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 fur
ther condition the soil,
a 3Qjj 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 mois
tened before tilling: however, extremely
wet soil will “ba!i-up” or clump during till
ing. Wait until the soil is less wet in orde
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 unfilled between passes.
Then go back between tilled rows. Then
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 trac
tion.
11
Page 12
To gel through a really tough section of
sod or hard ground, apply upward pres
sure on handle or lower the depth stake.
CULT IVAT IN G
Cultivating is destroying the weeds
between rows to prevent them from rob
bing 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.S cm). Lower the outer side
shields to protect small plants from being
buried.
e 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.
TiNE SH EAR PIN S
The tine assemblies on your tiller are
secured to the tine shaft with shear pins
{See “TINE REPLACEMENT’ in the
Service 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.

TINE REPLACEMENT
AcaUTION: Tines are sharp. Wear
gloves or other protection when handling
fries.
k badly worn tine causes your tiller to work
larder and dig more shallow. Most impor
ant, worn tines cannot chop and shred
>rganic matter as effectively nor bury it as
leeply as good tines. A tine this worn
leeds to be replaced.

oreTension
To maintain the superb tilling perfor
mance of this machine the tines should
be checked for sharpness, wear, and
bending, particularly the tines which are
next to the transmission. If the gap
between the tines exceeds 3-1/2 inches
they should be replaced or straightened
as necessary.
New tines should be assembled. Sharp

ImmecJiatefy prepare your tiller for storage
at the end of the season or if the unit will
not be used for 30 days or more,
AcAUTION: Never store the tilier 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 Customer Responsibilities 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 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.

« Touch up all rusted or chipped paint sur
faces; sand lightly before painting.
ENGINE
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 dam
age 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 sta
bilizer 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 carbure
tor. Do not drain the gas tank and carbu
retor if using fuel stabilizer.
ENGINE OIL
Drain oii (with engine warm) and replace
with clean oii. (See “ENGINE" in the
Customer Responsibilities section of this
manual).
CYLINDER
» Remove spark plug.
» Pour 1 ounce (29 m!) 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.
9 Replace your gasoline can it your can
starts to rust. Rust and/or dirt fn your
gasoline will cause problems.
9 If possible, store your unit indoors and
cover it to give protection from dust and
dirt.
9 Cover your unit with a suitable protective
cover that does not retain moisture. Do
not use piastic. 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.
