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.

* For normal tilling, set depth stake at the second or

third hole from the top.

WHEELS (See Fig. 6) Adjust wheels by removing the hairpin clip and clevis pin.

Tilt tiller back on its wheels and then re-level.

• With engine level, refill to point of overflowing ifneces- sary. Replace oil filler plug.

For cold weather operation you should change oil for easier starting (See "OIL VISCOSITY CHART" in the

Maintenance section of this manual). To change engine oil, see the Maintenance section of

this manual.

OIL FILLER

OIL LEVEL

Fig. 7

ADD GASOLINE

* Fill to within 1/2 inch of top of fuel tank to prevent

spills and to allow for fuel expansion. 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 deposits and reduce valve life). Do not mix oil with gasoline. Purchase fuel

in quantities that can be used within 30 days to assure fuel freshness.

CAUTION: Fill to within 1/2" of top of fuel tank to prevent spills and to allow

for fuel expansion, if gasoline is ac= cidentally 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 iNTEMPERATURES BELOW 32°F(0°C), USE FRESH, CLEAN WINTER GRADE GASOLINE TO

HELP INSURE GOOD COLD WEATHER STARTING.

CAUTION: Alcohol blended fuels (called gaso=

hol or using ethanol or methanol) can attract moisture which leads to separation and forma=

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 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 sea- son. 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 (See Fig. 8)

l CAUTION: Keep tine control in "OFF"

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 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. 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: Ifat a high altitude (3000 feet) or in cold tempera-

tures (below 32°F/0°C), the carburetor fuel mixturemay

need to be adjusted for best engine performance. See "TO ADJUST CARBURETOR" in the Service and

Adjustments section of this manual.

NOTE: Ifengine does not start, seetroubleshooting 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.

• Checktine operation and adjust ifnecessary. See "TINE OPERATION CHECK" in the Service and Adjustments

section of this manual.

You will find tilling much easier if you leave a row un- tilled 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.

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 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 grow-

ing 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 ofyour 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.

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 dig-

ging 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 will

allow tines to uproot weeds and leave the ground in rough condition, promoting nofurther growth of weeds

and grass (See Fig. 10).

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 50 hours of operation or at least

once a year ifthe 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 motor oil or equivalent. Tighten oil filler plug securely

each time you check the oil level.

TO CHANGE ENGINE OIL (See Figs. 11 and 12) Determine temperature range expected before oil change.

All oil must meet API service classification SG-SL.

• Be sure tiller is on level surface.

• Oil will drain more freely when warm.

• Catch oil in a suitable container.

• Remove drain plug.

• Tip tiller forward to drain oil.

• After oil has drained completely, replace oil drain plug and tighten securely.

STORAGE

Immediately prepare your tiller for storage atthe end of the season or if the unit will not be used for 30 days or more.

WARNING: 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 re- placement instructions inthe Service and Adjustments

section of this manual).

• Lubricate as shown inthe 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

ENGINE OIL

Drain oil (with engine warm) and replace with clean oil.

(See "ENGI NE" in the Maintenance section ofthis manual).

CYLINDER(S)

• 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 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.

• 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.

NOTE: Fuel stablizer 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 stablizer container. Run engine at least 10 minutes after adding

stablizer to allow the stabilizer to reach the carburetor. Do not drain the gas tank and carburetor if using fuel

stabilizer.
