DANGER

ENGINES GIVE OFF CARBON MONOXIDE, AN ODORLESS, COLORLESS, POISONOUS GAS. CARBON MONOXIDE MAY BE PRESENT EVEN IF YOU DO NOT SMELL OR SEE ANY ENGINE EXHAUST. BREATHING CARBON MONOXIDE CAN CAUSE NAUSEA, FAINTING OR DEATH, IN ADDITION TO DROWSINESS, DIZZINESS AND CONFUSION.

IF YOU EXPERIENCE ANY OF THESE SYMPTOMS, SEEK FRESH AIR AND MEDICAL ATTENTION IMMEDIATELY.

Engine Safety Precautions

If your product comes with a separate engine manual, be sure to read and follow all safety and warning precautions outlined there, in addition to any in this manual.

Preventing Carbon Monoxide Poisoning

•Always start and run engine outdoors. Do not start or run engine in an enclosed area, even if doors or windows are open.

•Never try to ventilate engine exhaust indoors. Carbon monoxide can reach dangerous levels very quickly.

•Never run engine outdoors where exhaust fumes may be pulled into a building.

•Never run engine outdoors in a poorly ventilated area where the exhaust fumes may be trapped and not easily taken away. (Examples include: in a large hole or areas where hills surround your working area.)

•Never run engine in an enclosed or partially enclosed area. (Examples include: buildings that are enclosed on one or more sides, under tents, car ports or basements.)

•Always run the engine with the exhaust and muffler pointed in the direction away from the operator.

•Never point the exhaust muffler towards anyone. People should always be many feet away from the operation of the engine and its attachments.

•Do not change the engine governor settings or overspeed the engine.

Gasoline Fires and Handling Fuel Safely

Use extra care in handling gasoline and other fuels. They are flammable and vapors are explosive.

•When storing extra fuel be sure that it is in an appropriate container and away from any fire hazards.

•Prevent fire and explosion caused by static electric discharge. Use only nonmetal, portable fuel containers approved by the Underwriter’s Laboratory (U.L.) or the American Society for Testing & Materials (ASTM).

•Never remove the fuel cap or add fuel with the engine running. Stop engine and allow to cool before filling.

•Never drain fuel from engine in an enclosed area.

CAUTION

HOT GASES ARE A NORMAL BY-PRODUCT OF A FUNCTIONING INTERNAL COMBUSTION ENGINE. FOLLOW ALL SAFETY INSTRUCTIONS TO PREVENT BURNS AND FIRES.

WARNING

NEVER ALTER OR MODIFY THE ENGINE FROM THE FACTORY. SERIOUS INJURY OR DEATH MAY OCCUR IF ENGINE IS MODIFIED OR ALTERED.

WHEN WORKING ON OR REPLACING PARTS FOR THE ENGINE OR PRODUCT, YOU MUST ALWAYS FLIP THE ON/OFF SWITCH TO THE OFF POSITION.

Adjusting Wheels and Drag Stake

The wheels on the cultivator can be adjusted to one of three positions. The LOW wheel position is used for transporting the cultivator across a smooth level surface while the engine is not running. The HIGH and HIGHEST wheel positions are used when cultivating in soil and help stabilize the unit when cultivating at different depths. SEE FIGURE 5

To Adjust Wheels Up Or Down do as follows: SEE FIGURES 5 & 6:

1.Pull the locking metal sleeve against the spring, away from the vertical guide until it releases from one of the three notched positions in the vertical guide.

2.Slide the wheel set up or down to the desired position, and release the locking metal sleeve until it locks into desired notch in the vertical guide.

To Adjust the Drag Stake do as follows: SEE FIGURE 7

The drag stake is used to help regulate cultivating depth and control the cultivator from leaping forward during operation. Resistance to forward motion is greatest when the drag stake is set in its lowest position allowing for deeper cultivation.

1.Pull the lock pin out of the drag stake mount hole.

2.Position drag stake so the pointed tip is directed downward.

3.Insert lock pin into the hole that achieves desired depth.

Engine Maintenance

Please read the maintenance schedule and observe these recommendations to extend the life of your engine.

Good maintenance is essential for safe, economical, and trouble-free operation. It will also help reduce air pollution. To help you properly care for your engine, the following pages include a maintenance schedule, routine inspection procedures, and simple maintenance procedures using basic hand tools. Other service tasks that are more difficult, or require special tools, are best handled by professionals and are normally performed by a technician or other qualified mechanic.

Maintenance, replacement or repair of the emissions control devices and systems may be performed by any non-road engine repair establishment or individuals. However, items must be serviced by an authorized dealer to obtain "no charge" emissions control service.

The maintenance schedule applies to normal operating conditions. If you operate your engine under unusual conditions, such as sustained high-load or high-temperature operation, or use in unusually wet or dusty conditions, consult your servicing dealer for recommendations applicable to your individual needs and use.

Spark Plug

The recommended spark plug is a Torch L7RTC which cross references to a Champion RCJ6Y.

1.Check spark plug at the beginning of each season.

2.Disconnect the spark plug cap, and clean any debris from around the spark plug area.

3.Remove spark plug and replace if any of the following occur; pitted electrodes, burned electrodes, cracked porcelain, or deposits around electrodes.

4.After analysis, seat spark plug and tighten with spark plug wrench. Reconnect the spark plug wire.

•Reinstall original spark plug, tighten additional 1/2 turn.

•Installing new spark plug, adjust spark plug gap to 0.027 inch and tighten additional 1/8 – 1/4 turn .

NOTE: A loose spark plug may overheat and damage engine. An over tightened spark plug may damage threads in the cylinder head.

Cooling Fins

Cooling fins, air inlets and linkages must be free from any debris before each use.

Carburetor

Never tamper with factory setting of the carburetor.

Air Filter

Never run engine without air cleaner properly installed. Added wear and engine failure may occur if air cleaner is not installed on engine.

Service air cleaner every 3 months or after 20 hours of operation. Clean filter daily in extremely dusty conditions.

To Replace or Clean Air filter, do as follows:

1.Before removing the air filter cover, move the choke lever to the CHOKE position.

DANGER

DO NOT SIPHON FUEL BY MOUTH. GASOLINE IS TOXIC AND CAN CAUSE SERIOUS PERSONAL INJURY.

NEVER STORE CULTIVATOR WITH FUEL IN THE FUEL TANK INSIDE AN ENCLOSED AREA OR BUILDING. FUEL VAPORS CAN COLLECT AND CAUSE A FIRE.

Transporting Your Cultivator

1.After using the cultivator and before transporting it, screw the gas cap on (clockwise) tightly. The gas cap will not leak during transporting if gas cap is tight. Never transport engine inside an enclosed space within a vehicle. Fuel or fuel vapors may ignite causing serious injury or death.

2.If fuel is present in the fuel tank, transport in an open vehicle in an upright position.

3.If an enclosed vehicle must be used, remove gas into an approved red fuel container. DO NOT siphon by mouth.

4.Run engine to use up the fuel in the carburetor and fuel tank. Always run engine in a well ventilated area.

5.Wipe away any spilled fuel from engine and cultivator. Allow to dry.

6.Ensure gas cap is shut tightly before transporting cultivator in a vehicle.

Long-Term Storage

If your cultivator will not be used for more than one month, prepare it for long term storage.

Steps for Long-Term Storage

1.Mix an appropriate amount of fuel stabilizer to fresh gasoline in the ratio recommended on the stabilizer packaging. Run the engine for five minutes to distribute the stabilizer mixture throughout the fuel system. This will prevent gum, varnish and corrosion build up in your fuel system during long-term storage for up to 12 months.

2.Store cultivator in an upright position.

3.Remove all debris from cultivator tines and engine.

15073 BORDER-EDGER KIT INSTALLATION (OPTIONAL ACCESSORY)

The Border-Edger Kit is a useful tool for making clean cuts in the lawn along the borders of gardens, flower beds, walkways, and driveways for a well manicured look. To install the BorderEdger Kit, do the following:

INSTALLATION

1.Make sure the cultivator is not running by turning the ON/ OFF switch to the OFF position.

2.Remove the hairpins from both sides of the tine shaft.

3.Remove the cultivating tines from the shaft.

4.Remove the drag stake and lock pin from the unit.

5.Store the tines and save the (2) hairpins; they will be used on the Border-Edger Kit.

6.Slide the border-edger tine onto either side of the tine shaft. Make sure that the hub collar of the border-edger tine faces outward, away from the transmission of the cultivator.

SEE FIGURE 10

7.Take the (2) hairpins saved in Step 4 and insert them through the inner and outer holes in the tine shaft on each side of the border-edger tine to secure the tine blade in place on the shaft. SEE FIGURE 10

8.Slide the border-edger wheel onto the opposite side of the tine shaft as far as it will go.

9.Insert the remaining (1) hairpin, that came with the kit, through the inner hole to secure the wheel. SEE FIGURE 10

10.Set the cultivator wheels to the HIGHEST (top) position.
