• If depth stake is not controlling forward action, lower the depth stake If the unit is not going forward, raise the depth stake

CAUTION: KEEP AWAY FROM THE ROTATING TINES. ROTATING TINES CAN CAUSE INJURY.

• GASOLINE IS FLAMMABLE AND CAUTION MUST BE USED WHEN HANDLING OR STORING IT. DO NOT FILL FUEL TANK WHILE MINI TILLER/CULTIVA• TOR IS RUNNING, HOT, OR WHEN MINI 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 1/4-1/2 INCH FROM THE TOP TO PROVIDE SPACE FOR EXPANSION OF FUEL. ALWAYS FILL FUEL TANK OUTDOORS AND USE A FUNNEL OR SPOUT TO PREVENT SPILL· ING. MAKE SURE TO WIPE UP ANY SPILLED FUEL BEFORE STARTING THE ENGINE. STORE GASOLINE IN A CLEAN, APPROVED CONTAINER, 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 ..

BEFORE STARTING ENGINE

FILL GAS
The two cycle engine used on this mini 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 premixed in a clean gasoline container Always use fresh, clean unleaded gasoline
WARNING: Experience indicates that alcohol blended fuels (called gasahol 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

GASOLINE AND OIL MIXTURE
Mix gasoline and oil (See Fig 7) 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 SAE 30 or SAE 40 two-cycle oil into the gasoline container

IMPORTANT: DO NOT USE OUTBOARD MOTOR OIL OR MUL Tl-VISCOSITY OILS, SUCH AS 10W-30 OR 10W-40 ..

• 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)

• This completes the special gasoline mixing (24:1) procedure. It can now be poured into the mini tiller/ cultivator fuel tank

IMPORTANT: DO NOT FILL FUEL TANK WITH GASO- LINE THAT DOES NOT HAVE OIL MIXED IN IT DO NOT USE GASOLINE
ADDITIVES BECAUSE THE ENGINE MAY BE DAMAGED SHAKE THE GASOLINE CONTAINER BEFORE EACH FILLING OF THE FUEL TANK

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 6)tothe FULL choke position (all the way down)

NOTE: A warm engine should not require choking
CAUTION: DO NOT TOUCH THE
THROTTLE CONTROL WHILE STARTING THE ENGINE. THE MINI TILLER/ CULTIVATOR WILL PROPEL ITSELF IF THE ENGINE SPEED IS ADVANCED FROM IDLE.

• Tilt the mini tiller/cultivator back on the depth stake or transport wheels to raise the tines off the ground
• Grasp the upper handle firmly to stabilize the mini tiller/cultivator and pull the starter handle with short quick pulls Do not allow the starter handle to snap back, let ii 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 ttle throttle control and move the shut-off switch to the OFF position
• If the engine becomes flooded, see the Spark Plug Maintenance paragraph ·1n the Maintenance section of this manual Then pull the starter rope with ttle choke “OFF”

CAUTION: THE MUFFLER AND SURROUNDING AREAS BECOME HOT AFTER RUNNING THE ENGINE, AVOID THESE AREAS,

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 .. A tiller will also clear the soil of unwanted vegetation The decomposition of this vegetation 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
• 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 relatively small area is tilled properly and the tilled ground used soon aftertillingto preserve the moisture content
• The depth stake (on the back of the mini tiller/ cultivator)serves a dual purpose (see Fig 8) It helps regulate the depth of the cut to a uniform level and also acts as a brake to help the operator control the speed of the mini tiller/cultivator.

• Lowering the depth stake will slow the mini tiller/ cultivator and make it till deeper Raising the depth bar will allow the mini tiller/cultivator to move faster and till more shallow.
• If the tiller mini tiller/cultivator stops forward motion and 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 un germinated weed seeds. You may want to raise the depth bar to lessen the braking action
• When cultivating around plants or close areas you may want to remove the outside tines (see Tine Replacement paragraph in the Service/ Adjustments section of this manual) ..
