THESE SAFETY RULES ARE FOR YOUR PROTECTION. READ THEM CAREFULLY
IMPORTANT
SAFETY STANDARDS REQUIRE OPERATOR PRESENCE CONTROLS TO MINIMIZE THE RISK OF INJURY. YOUR TILLER/ CULTIVATOR IS EQUIPPED WITH SUCH CONTROLS. DO NOT ATTEMPT TO DEFEAT THE FUNCTION OF THE OPERATOR PRESENCE CONTROL UNDER ANY CIRCUMSTANCES.
BEFORE USE
Read the owner’s manual carefully. Be thor- oughly familiar with the controls and the proper use of the tiller/cultivator. Know how to stop the tiller/cultivator and disengage the controls quickly.
Do not operate the tiller/cultivator without wearing adequate outer garments. Wear footwear that will improve footing on slippery surfaces.
Keep the area of operation clear of all persons, particu­larly small children and pets.
Thoroughly inspect the area where the tiller/ cultivator is to be used and remove all foreign objects.
FUEL SAFETY
Handle fuel with care; it is highly flammable.
Use an approved container.
Check fuel supply before each use, allowing space for
expansion as the heat of the engine and/or sun can cause fuel to expand.
Fill fuel tank outdoors with extreme care. Never fill fuel tank indoors. Replace fuel tank cap securely and wipe up spilled fuel.
Never remove the fuel tank cap or add fuel to a running or hot engine.
Never store fuel or tiller/cultivator with fuel in the tank inside a building where fumes may reach an open flame.
OPERATING SAFETY
Never allow children or young teenagers to operate the tiller/cultivator. Keep them away while it is operating. Never allow adults to operate the tiller/cultivator without proper instruction.
Always wear safety glasses or eye shields during operation or while performing an adjustment or repair to protect your eyes from foreign objects that may be thrown from the tiller/cultivator.
Do not put hands or feet near or under rotating parts.
Exercise extreme caution when operating on or crossing gravel drives, walks, or roads. Stay alert for hidden hazards or traffic.
Exercise caution to avoid slipping or falling.
Never operate the tiller/cultivator without proper
guards, plates, or other safety protective devices in place.
Never operate the tiller/cultivator at high transport speeds on slippery surfaces. Look behind and use care when backing.
Never allow bystanders near the tiller/cultivator.
Keep children and pets away while operating.
Never operate the tiller/cultivator without good
visibility or light.
Do not run the engine indoors. The exhaust fumes are dangerous (containing CARBON MONOXIDE, an ODORLESS and DEADLY GAS).
Take all possible precautions when leaving the tiller/cultivator unattended. Stop the engine.
Do not overload the tiller/cultivator capacity by attempting to till too deep at too fast a rate.
SAFE STORAGE
Always refer to the owner's manual instructions for important details if the tiller/cultivator is to be stored for an extended period.
Never store the tiller/cultivator with fuel in the fuel tank inside a building where ignition sources are present such as water and space heaters, clothes dryers, and the like. Allow the engine to cool before storing in any enclosure.
Keep the tiller/cultivator in safe working condition. Check all fasteners at frequent intervals for proper tightness.
FUEL SAFETY
After striking a foreign object, stop the engine (motor). Remove the wire from the spark plug, and keep the wire away from the plug to prevent accidental starting. Thoroughly inspect the tiller/cultivator for any damage, and repair the damage before restarting and operating the tiller/cultivator.
If the tiller/cultivator should start to vibrate abnormally, stop the engine (motor) and check immediately for the cause. Vibration is generally a warning of trouble.
Stop the engine (motor) whenever you leave the operating position. Also, disconnect the spark plug wire before unclogging the tines and when making any repairs, adjustments, or inspections.
When cleaning, repairing, or inspecting, shut­off the engine and make certain all moving parts have stopped.
Never attempt to make any adjustments while the engine is running (except when specifically
recommended by the manufacturer).
LOOK FOR THIS SYMBOL TO POINT OUT IMPORTANT SAFETY PRECAUTIONS. IT MEANS ATTENTION!!! BECOME ALERT!!! YOUR SAFETY IS INVOLVED.

CAUTION: ALWAYS WEAR SAFETY GLASSES OR EYE SHIELDS WHILE ASSEM­BLING TILLER/CULTIVATOR.
FIG. 1-OP on page 6 shows the tiller/cultivator completely
assembled. Reference to the right and left hand side of the
tiller/cultivator is from the operator's position behind the unit.
TO INSTALL THE HANDLE ASSEMBLY
The lower handles have a short bend at the bottom end and are flattened at the top to allow the upper handle to be placed between the lower handles. To assemble the handles, do the following:
Unwind the throttle control from around the engine and straighten the cable. Be careful you do not kink the cable.
Remove two locknuts, four spacers and two handle mounting screws from the tine shield (See FIG. 1- ASSY).
Insert the right side lower handle section into the mounting channel between the tine shield and the engine casting (See FIG. 2-ASSY). Push the mounting screws through the tine shield , handle and approxi mately halfway into the engine casting. Be sure a spacer is on each mounting screw (See FIG. 3-ASSY). It may be necesary to rotate the lower handle to align the mounting holes. To allow proper mounting of the upper handle section be sure the flat portion of the lower handle is facing inward.
Position the left side lower handle section into the mounting channel between the tine shield and the engine casting. Align the holes in the handle with the engine casting and the tine shield, then push the mounting screws completely through the engine casting, tine shield and handle. Install a spacer onto the mounting screws and secure the lower
handle sections using two locknuts previously removed (See FIG . 3-ASSY). Finger tighten the
locknuts at this time.
Remove hardware from upper handle.
Place the upper handle between the lower handles (See
FIG. 4-ASSY) and secure with two curved head carriage bolts, two formed washers, two 11/32 inch flatwashers and two tee knobs (removed earlier) on the inside of the handle. You must insert a hex nut into each tee knob. Finger tighten only. Pull back on the tee knob to engage the hex opening with the hex nut. Tighten the tee knob. The nut will be pulled into the cavity and locked. The lower handles have two holes at the top end to allow the upper handle to be positioned at two different heights.
Using two 7/16 inch wrenches, tighten the locknuts on the
screws in the lower ends of the lower handles just enough to hold the lower handles firmly in place.

OPERATION
The operation of this tiller/cultivator can result in foreign objects being thrown into the eyes, which can result in severe eye damage. Always wear safety glasses or eye shields while operating the tiller/cultivator. We recommend standard safety glasses or Wide Vision Safety Mask for over your glasses.
CAUTION: KEEP AWAY FROM THE ROTATING PARTS. ROTATING PARTS CAN CAUSE INJURY.
TO STOP TILLER/CULTIVATOR
Release the throttle control to stop the tines.
Move the shut-off switch on the engine to the
"OFF" position.
TO OPERATE CULTIVATOR
Set the depth rod to the desired tilling position as
follows: Remove the hairpin cotter from the clevis pin
securing the depth rod (See FIG. 1-OP). Remove the clevis pin and adjust the depth rod upward to dig shallower or downward to dig deeper. Reinstall the clevis pin and hairpin cotter.
With engine running, tilt the unit back on the depth bar until the tines are off the ground and squeeze the throttle control all the way up against the hand grip. The engine is governor controlled and should be run at full throttle.
Grasp the handles firmly and slowly tilt the unit forward to begin the tilling action.
As the tines begin to make contact with the ground, hold back on the handles so that the tines will dig and not ride forward over the ground. Hold back until the tines dig into the soil.
If the tilled depth is too deep or too shallow, turn off the engine and reset the depth rod.
If depth rod is not controlling forward action, lower the depth rod. If the unit is not going forward, raise the depth rod.
BEFORE STARTING ENGINE FILL GAS
The two cycle engine used on this tiller/cultivator requires a mixture of gasoline and oil for lubrication of the bearings and other moving parts. The correct fuel mixture ratio is 24:1 (See Fuel Mixture Chart). Gasoline and oil must be pre-mixed in a clean gasoline container. Always use fresh, clean unleaded gasoline.
CAUTION: GASOLINE IS FLAMMABLE AND CAUTION MUST BE USED WHEN HANDLING OR STORING IT. DO NOT FILL FUEL TANK WHILE TILLER/CUL­TIVATOR IS RUNNING, HOT, OR WHEN
TILLER/CULTIVATOR IS IN AN EN­CLOSED AREA. KEEP AWAY FROM OPEN FLAME, ELECTRICAL SPARK, AND DO NOT SMOKE WHILE MIXING FUEL OR FILLING THE FUEL TANK. NEVER FILL FUEL TANK COMPLETELY; BUT FILL THE TANK TO WITHIN 1/2 INCH FROM THE TOP TO PROVIDE SPACE FOR EXPANSION OF FUEL. ALWAYS FILL FUEL TANK OUTDOORS AND USE A FUNNEL OR SPOUT TO PREVENT SPILLING. MAKE SURE TO WIPE UP ANY SPILLED FUEL BEFORE STARTING
ENGINE. STORE GASOLINE IN A CLEAN, APPROVED CON-
TAINER, AND KEEP THE CAP IN PLACE ON THE CONTAINER. KEEP GASOLINE IN A COOL, WELL VENTILATED PLACE; NEVER IN THE HOUSE. NEVER BUY MORE THAN A 30 DAY SUPPLY OF GASOLINE TO ASSURE VOLATILITY. GASOLINE IS INTENDED TO BE USED AS A FUEL FOR INTERNAL COMBUS­TION ENGINES; THEREFORE, DO NOT USE GASO­LINE FOR ANY OTHER PURPOSE. SINCE MANY CHIL­DREN LIKE THE SMELL OF GASOLINE, KEEP IT OUT OF THEIR REACH BECAUSE THE FUMES ARE DAN­GEROUS TO INHALE, AS WELL AS BEING EXPLO­SIVE.
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 emptied before storage for 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.

OPERATION
GASOLINE AND OIL MIXTURE
Mix gasoline and oil as follows:
Pour 1 U.S. quart of fresh, clean, unleaded automo­tive gasoline into a gallon gasoline container.
Add (5 oz.) of clean, high quality two-cycle oil into the gasoline container.
IMPORTANT: DO NOT USE OUTBOARD MOTOR
OIL OR MULTI-VISCOSITY OILS, SUCH AS 10W-30 OR 10W-40. DISREGARD MIX RATIO INFORMA­TION ON OIL CONTAINTER IF INSTRUCTIONS CONFLICT WITH FUEL MIXTURE CHART BELOW.
Reinstall the cap on the gasoline container and shake container vigorously so the oil mixes with the gasoline.
Add an additional 3 U.S. quarts of gasoline to the gallon container and shake the container again.
FUEL MIXTURE CHART (Mixture 24:1)
U. S. S. I. (METRIC)
GAS OIL GAS OIL 1 Gal. 5 oz. 4 Liters .167 L 2 Gal. 11 oz. 8 Liters .333 L 5 Gal. 27 oz. 20 Liters .833 L
This completes the special gasoline mixing (24:1) procedure. It can now be poured into the tiller/ cultivator fuel tank.
IMPORTANT: DO NOT FILL FUEL TANK WITH
GASOLINE THAT DOES NOT HAVE OIL MIXED IN IT. DO NOT USE GASO LINE ADDITIVES BECAUSE THE EN­GINE MAY BE DAMAGED. SHAKE THE GASOLINE CONTAINER BE­FORE EACH FILLING OF THE FUEL TANK.
CAUTION: DO NOT TOUCH THE THROTTLE CONTROL WHILE STARTING THE ENGINE. THE TILLER/CULTIVATOR WILL PROPEL IT­SELF IF THE ENGINE SPEED IS ADVANCED FROM IDLE.
Tilt the tiller/cultivator back on the depth rod or transport wheels to raise the tines off the ground.
Grasp the upper handle firmly to stabilize the tiller/cultivator and pull the starter handle with short quick pulls. Do not allow the starter handle to snap back, let it rewind slowly while holding the starter rope. It will take a few pulls on the starter handle to feed gas from the fuel tank to the carburetor.
When engine starts, move the choke control to 1/2 choke position until the engine runs smoothly. Then move choke control to (OFF) position.
If engine falters, move choke control to 1/2 choke position until engine runs smoothly. Then move choke control to (OFF) position.
If engine fires, but does not continue to run, move choke control to no choke position and repeat starting instructions.
NOTE: If the tines do not stop when the throttle control is released, adjust the carburetor idle speed as instructed in
Step 5 of Carburetor Adjustment paragraph in the Service/ Adjustments section of this manual.
To stop the engine, release the throttle control and move the shut-off switch to the (OFF) position.
If the engine becomes flooded, see the Spark Plug Maintenance paragraph in the Maintenance sec-
tion of this manual. Then pull the starter rope with the choke control in the (OFF) position.
CAUTION: THE MUFFLER AND SURROUND­ING AREAS BECOME HOT AFTER RUNNING THE ENGINE. AVOID THESE AREAS.
TO START THE ENGINE
Before starting the engine, be sure you have read and under­stood all the instructions on the preceding pages.
Fill the fuel tank (to 1/2 inch below the bottom of the fill neck) with fresh fuel mix and reinstall the
fuel tank cap securely. Never use fuel that may be stale from long periods of storage.
Move the shut-off switch to the (ON) position.
Move the choke control (see FIG. 1-OP) to the (FULL)
choke position (all the way down).
NOTE: A warm engine should not require choking.

OPERATION
TILLING HINTS
Tilling is digging in, turning over and breaking up packed soil before planting. Loose unpacked soil helps root growth. Best tilling depth is 4 to 6 inches. Tilling will also clear the soil of unwanted vegetation. The decomposi tion of this vegetation matter enriches the soil. De pending 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.
Avoid tilling the soil that is too dry as the soil pulverizes and produces a dust that will not hold water. Also, tilling soil that is too wet will produce unsatisfactory clods besides being hard on the machine.
Better growth will be obtained in tilled ground if a rela tively small area is tilled properly and the tilled ground used soon after tilling to preserve the moisture content.
The depth rod (on the back of the tiller/cultivator) serves a dual purpose (See FIG. 2-OP). It helps regulate thedepth of the cut to a uniform level and also acts as a brake to help the operator control the speed of the tiller/cultivator. Also, with the wheels down, it is used for transporting the unit.
Lowering the depth rod will slow the tiller/cultivator and make it till deeper. Raising the depth rod will allow the tiller/cultivator to move faster and till more shallow.
If the tiller/cultivator stops forward motionand tries to dig deeper than necessary, move the handles from side to side to start forward motion.
CULTIVATING HINTS
When cultivating (weed killing) it is best to till no deeper than 1-1/2 inches. Tilling deeper will only pull to the surface ungerminated weed seeds.You may want to raise the depth rod to lessen the braking action.
When cultivating around plants or close areas you may want to remove the outside tines (See Tine Replace
ment paragraph in the Service/Adjustments section of this manual).

SERVICE & ADJUSTMENTS

TINE REPLACEMENT
The tiller/cultivator is left hand or right hand as viewed from the operator's position behind the unit.
All four tines on this unit are different and cannot be inter­changed. The tines must be properly installed as shown in figures 1 and 2 or the tiller/cultivator will not function properly.
The outside tines may be removed to reduce the tilling width to about 6 inches, for working close around plants or in small areas, if desired. When reinstalling the outside tines see below.
CAUTION: THE TINES ARE SELF-SHARP­ENING AND WILL BECOME QUITE SHARP FROM USE. HANDLE CAREFULLY.
The tines will all wear fairly evenly. If the tines are being replaced because of wear, we recommend that all four tines be replaced at the same time. To replace the tines, do the following:
Place the shut-off switch to the (OFF) position and disconnect the spark plug wire.
Remove the hairpins and the clevis pins from the tines on one side of the unit and remove the tines (See FIG.. 1-SERV.&ADJ.).
Clean the tine shaft and oil the shaft at the tine locations.
Place the inside tine on the tine shaft and reinstall the
clevis pin and hairpin.
When the tines are properly installed, the letter "R" will be visible on the outside of the right-hand tine (the letter "L" on the left-hand tine). The letter should appear opposite the small hole in the side of the tine.
Place the outside tine on the tine shaft and reinstall the clevis pin and hairpin cotter.
The outside tine cutting tips will all bend in toward the inside tine. The letter "R" on the right side or "L" on the left side should be visible from the outside of the unit.
Repeat steps on the opposite side of the unit.
Check to make sure the tines are installed on correct side
of the unit (See FIG. 2-SERV.&ADJ).

Note this location.
b. Turn the mixture adjusting screw slowly counterclock-
wise until the engine starts to sputter. Note this location.
c. Turn the mixture adjusting screw clockwise until it is
halfway between the first position where the engine faltered and the second position where the engine started to sputter.
The idle speed may need to be adjusted after making the mixture adjustment. If the tines do not turn when the engine is running and the throttle control is released, the idle speed will not need adjusting. If the tines turn when thethrottlecontrol is released, do the following:
a. Have someone hold the tiller/cultivator back on the depth
bar with the tines off the ground.
b. Start the engine. c. With the throttle in the released (idle) position, turn the
idle speed adjusting screw counter-clockwise until the tines stop rotating.

STORAGE

CAUTION: NEVER STORE ENGINE WITH FUEL IN TANK INDOORS OR IN ENCLOSED, POORLY VENTILATED AREA, WHERE FUEL FUMES MAY REACH AN OPEN FLAME, SPARK OR PILOT LIGHT AS ON A FURNACE, WATER HEATER, CLOTHES DRYER, ETC.
NOTE: The tiller/cultivator should be immediately prepared for
storage at the end of the season or if the unit will not be used for 30 days or more.
TILLER/CULTIVATOR
Thoroughly clean the tiller/cultivator. Remove all dirt and debris from the engine and unit.
Remove the tines and oil the tine shaft and reinstall the tines (See Service/Adjustments section in thismanual).
Loosen the tee knobs that secure the upper handle to the lower handle.
Carefully fold the upper handle down making sure the throttle is not kinked. Tighten the tee knobs.
The cross piece of the upper handle (between the lower handles) can now be used as a carry handle or can be
hooked over a wall hook to store the tiller/cultivator up off the floor out of the way.
NOTE: A yearly checkup or tuneup by a competent repairman is a good way to insure that your tiller/cultivator will provide maximum performance for the next season.
Drain the fuel from the fuel tank into an approved container outdoors, away from open flame.
Start and run the engine until it stops due to lack of fuel.
Pull the starter handle slowly until you feel resistance due
to compression pressure, then stop.
Release the starter tension slowly to prevent the engine from reversing due to compression pressure. This position will close both the intake and exhaust ports to prevent corrosion of the piston and cylinder bore.
OTHER
If possible, store your tiller/cultivator indoors and cover it to give protection from dust and dirt.
Cover the tiller/cultivator with a suitable protective cover that does not retain moisture. Do not use plastic.
IMPORTANT:NEVER COVER THE TILLER/
CULTIVATOR WHILE THE ENGINE AND EXHAUST AREAS ARE STILL WARM.
ENGINE
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 INDICATE THAT ALCOHOL BLENDED FUELS (CALLED GASO­HOL OR USING ETHANOLOR 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.
