BEFORE STARTING ENGINE 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
containers, use clean fill funnels. CHECK ENGINE OIL LEVEL
The engine in your unit has been shipped, from the factory, already filled with SAE 30 summer weight oil.
1. With engine level, clean area around oil filler plug and remove plug.
2. Engine oil should be to point of over- flowing when engine is level.
For approximate capacity see "PROD-
UCT SPECIFICATIONS" on page 3 of
this manual. All oil must meet A.P.I. Service Classification SF-SJ.
For cold weather operation you should
change oil for easier starting (See oil viscosity chart in the Maintenance sec-
tion of this manual).
To change engine oil, see the Mainte-
nance section in this manual.
TO TRANSPORT
_CAUTION: Before lifting or transporting,
allow tiller engine and muffler to cool. Dis- connect spark plug wire. Drain gasoline
from fuel tank. AROUND THE YARD
1. 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 position. This prevents tines from scuffing the ground.
2. Place shift lever indicator in "F" (for- ward) position for transporting.
3. Hold the drive control bar against the handle to start tiller movement. Tines
will not turn.
4. Move throttle control to desired speed.
AROUND TOWN
1. Disconnect spark plug wire.
2. Drain fuel tank.
3. Transport in upright position to prevent oil leakage.
Oil
ADD GASOLINE
Fill fuel tank to bottom of filler neck. Do not overfill. Use fresh, clean, regular unleaded gasoline with a minimum of
87 octane. (Use of leaded gasoline will
increase carbon and lead oxide depos- its and reduce valve life). Do not mix oil
with gasoline. Purchase fuel in quan- tities that can be used within 30 days to
assure fuel freshness. AI_CAUTION: Fill to within 1/2 inch of top of fuel tank to prevent spills and to allow
for fuel expansion. If gasoline is acci- dentally spilled, move machine away from area of spill. Avoid creating any source of ignition until gasoline vapors have disap- peared. Wipe off any spilled oil or fuel. Do not store, spill or use gasoline near an open
flame. IMPORTANT: When operating in temper-
atures below32°F(0°C), use fresh, clean winter grade gasoline to help insure good cold weather starting.
10
CAUTION: Alcohol blended fuels (called gasohol or using ethanol or methanol) can attract moisture which leads to separa- tion 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 Instructions for additional information. Never use engine or carburetor cleaner products in the fuel tank or permanent damage may occur.
TO START ENGINE
AI_CAUTION: Keep drive control bar in "DISENGAGED" 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.
1. Make sure spark plug wire is properly connected.
2. Move shift lever indicator to "N" (neu- tral) position.
3. Place throttle control in "FAST' posi- tion.
4. Turn fuel shut-off valve 1/4 turn to open position.
5. Move choke control to choke position.
6. 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 pull slightly harder at this
point).
7. Pull recoil starter handle quickly. Do
not let starter handle snap back
against starter.
NOTE: If engine fires but does not start, move choke control to half choke posi-
tion. Pull recoil starter handle until engine starts.
8. When engine starts, slowly move choke control to "RUN" position as
engine warms up.
NOTE: A warm engine requires less choking to start.
9. Move throttle control to desired running position.
10.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 trou-
bleshooting points.

TILLING HINTS
I(_CAUTION: Until you are accustomed to handling your tiller, start actual field
use with throttle inslow position (mid-way between "FAST" and "IDLE").
Tilling is digging into, turning over, and breaking up packed soil before plant-
ing. Loose, unpacked soil helps root growth. Best tilling depth is 4" to 6". 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 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 "ball-up" or clump during till- ing. 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 negoti- ate 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
traction. To get through a really tough section of sod or hard ground, apply
upward pressure on handle or lower the depth stake.
11
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" to 3"
(2.5-7.5 cm). Lower the outer side shields to protect small plants from being buried.
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.
ADJUST WHEELS FOR
CULTIVATING
1. Place blocks under right hand side of tiller and remove hairpin clip and clevis
pin from right hand wheel.
2. Move wheel outward approximately 1 inch until hole in inner wheel hub lines
up with inner hole in axle.
3. Replace clevis pin and hairpin clip on inside of wheel and remove blocks.
4. Repeat preceding steps on left hand
side.
NOTE: In extremely rough conditions and
while cultivating, the wheels should be
moved outward on the axle for increased
stability.

TEMPERATU RE RANGE ANTICIPATED BEFORE NEXT OIL CHANGE
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 oil 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 mo- tor oil or equivalent. Tighten oil filler plug
securely each time you check the oil level. TO CHANGE ENGINE OIL
Determine temperature range expected
before oil change. All oil must meet API service classification SF-SJ.
Be sure tiller is on level surface.
Oil will drain more freely when warm.
Use a funnel to prevent oil spill on tiller, and catch oil in a suitable container.
1. Remove drain plug.
2. Tip tiller forward to drain oil.
3. After oil has drained completely,
replace oil drain plug and tighten se- cu rely.

TINE REPLACEMENT
_CAUTION: Tines are sharp. Wear gloves or other protection when handling
tines. A badly worn tine causes your tiller to work harder and dig more shallow. Most
important, worn tines cannot chop and shred organic matter as effectively nor bury it as deeply as good tines. A tine this worn needs to be replaced.
New Tine
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- ened tine edges will rotate rear
