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. Change wheel position. Replace the hairpin clip and clevis pin.

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 AP PROVED, 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 ap prox­i mate ca pac i ty see “PRODUCT SPEC I FI CA TIONS” on page 3 of this manual.
Tilt tiller back on its wheels and then re-level.
With engine level, refill to point of overflowing if nec­ es sary. Re place 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 Level
Max Upper Level
Min Lower Level
Fig. 7
ADD GASOLINE
Fill fuel tank to bottom of filler neck. Do not overfill. Use fresh, clean, regular un lead ed 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 quan ti ties that can be used within 30 days to assure fuel freshness.
Oil Filler Plug
CAUTION: Fill to within 1/2 inch of top of fuel tank to prevent spills and to allow for fuel expansion. If gasoline is ac­ ci den tal ly 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 IN TEMPERATURES
BELOW32°F(0°C), USE FRESH, CLEAN WINTER GRADE GAS O LINE TO HELP INSURE GOOD COLD WEATHER START ING.
CAUTION: Alcohol blended fuels (called gas o hol or using ethanol or methanol) can at­tract moisture which leads to sep a ra tion and for ma 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 stor age 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 In struc tions 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)
CAUTION: KEEP TINE CONTROL IN “OFF” PO SI TION WHEN STARTING ENGINE.
When starting engine for the first time or if engine has run out of fuel, it will take ex tra pulls of the recoil starter to move fuel from the tank to the engine.
1. Make sure spark plug wire is prop er ly connected.
2. Place the fuel valve to the "ON" position.
3. To start a cold engine, move the choke lever to the "ON" position.
4. Move the throttle lever away from the "SLOW" position, about 1/3 of the way toward the "FAST" position.
5. Turn the engine switch to the "ON" position. Pull rope out slowly until engine reaches start of com pres sion cy cle (rope will pull slightly harder at this point).
6. Pull recoil starter handle quickly. Do not let starter handle snap back against starter. Repeat if neces­sary.
NOTE: IF ENGINE FIRES BUT DOES NOT START, MOVE CHOKE CONTROL TO HALF CHOKE POSITION. PULL RECOIL STARTER HANDLE UNTIL ENGINE STARTS.
7. If the choke lever has been moved to the "ON" position to start the engine, gradually move it to the opposite position as the engine warms up.
NOTE: A WARM ENGINE REQUIRES LESS CHOK ING TO START.
8. Move throttle control to desired running position.
9. Allow engine to warm up for a few min utes before engaging tines.
NOTE: IF ENGINE DOES NOT START, SEE TROU BLE SHOOT ING

Soil conditions are important for proper tilling. Tines will not readily penetrate dry, hard soil which may con trib ute 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 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. (See Fig. 9) There are two reasons for doing this. First, wide turns are much easier to negotiate than about-faces. Sec ond, 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.
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 Ad just ments sec tion of this manual.
TILLING HINTS
CAUTION: Until you are accustomed to handling your tiller, start ac tu al 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.
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".
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 con di tion, promoting no fur ther growth of weeds and grass (See Fig. 10).
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 con di tion. (The harder or wetter the ground, the slower the engine and tine speed needed. Under these poor con di tions, 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 vege ta tion. The de com po si tion of this vegetable mat ter en rich es the soil. De pend ing on the climate (rain fall and wind), it may be advisable to till the soil at the end of the growing season to further condition the soil.

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 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.

WARNING: Never store the tiller with gasoline in the tank inside a build ing 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 nec es sary (See belt re­ place ment in struc tions in the Service and Ad just ments 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, break age 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 “ENGINE” in the Maintenance section of this man ual).
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 pro tec tive cover that does not retain moisture. Do not use plastic. Plastic cannot breathe which allows con den sa tion to form and will cause your unit to rust.
IMPORTANT: NEVER COVER TILLER WHILE ENGINE AND EXHAUST AREAS ARE STILL WARM.
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.
Empty the fuel tank by starting 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.
Use fresh fuel next season.
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 empty the gas tank and carburetor if using fuel stabilizer.
