Add fuel in a clean,
well ventilated
outdoor area. Wipe up any spilled fuel
immediately. Avoid creating a source of
ignition for spilt fuel. Do not start the engine
until fuel vapors dissipate.
WARNING:
Gasoline is
extremely
flammable. Ignited Vapors may explode.
Always stop the engine and allow it to cool
before filling the fuel tank. Do not smoke
while filling the tank. Keep sparks and open
flames at a distance from the area.
WARNING:
Remove fuel cap
slowly to avoid injury
from fuel spray. Never operate the unit
without the fuel cap securely in place
.
WARNING:
RECOMMENDED FUEL TYPE
Old fuel is the primary reason for improper
unit performance. Be sure to use fresh,
clean, unleaded gasoline.
NOTE: This is a four cycle engine. In order to avoid
damage to the unit, do not mix oil with gasoline.
Definition of Blended Fuels
Today's fuels are often a blend of gasoline and
oxygenates such as ethanol, methanol or MTBE (ether).
Alcohol-blended fuel absorbs water. As little as 1%
water in the fuel can make fuel form acids when stored.
When using alcohol-blended fuel, use fresh fuel that is
less than 60 days old.
Using Blended Fuels
If you choose to use a blended fuel, or if its use is
unavoidable, follow recommended precautions:
• Always use fresh unleaded gasoline
• Use the fuel additive STA-BIL
®
or an equivalent
• Drain tank and run the engine dry before storing unit
Using Fuel Additives
The use of fuel additives, such as STA-BIL®Gas
Stabilizer or an equivalent, will inhibit corrosion and
minimize the formation of gum deposits. Using a fuel
additive can keep fuel from forming harmful deposits in
the carburetor for up to six (6) months. Add 0.8 oz.
(23 ml.) of fuel additive per gallon of fuel according to the
instructions on the container. NEVER add fuel additives
directly to the unit's gas tank.
OIL AND FUEL INFORMATION
FUELING THE UNIT
1. Remove fuel cap. Remove the tag from the fuel tank
neck.
NOTE: Fill or add fuel to the tank only when the
cultivator is in a horizontal position (Fig. 9).
2. Place spout of gas container into the fill hole on the
fuel tank and fill tank.
NOTE: Do not overfill tank.
3. Wipe up any gasoline that may have spilled.
4. Reinstall the fuel cap.
5. Move the unit at least 30 ft. (9.1 m) from the fueling
source and site before starting the engine.

MAINTENANCE AND REPAIR INSTRUCTIONS
CLEANING THE UNIT
• Use a small brush to clean off the outside of the unit
and to keep the air vents free of obstructions.
• Do not use strong detergents or petroleum based
cleaners, such as kerosene. Some household
cleaners contain aromatic oils such as pine and
lemon that can damage the plastic housings or
handles. Wipe off any moisture with a soft cloth.
STORAGE
• Never store the unit with fuel in the tank where
fumes may reach an open flame or spark.
• Allow the engine to cool before storing.
• Store the unit in a locked up area to prevent
unauthorized use or damage.
• Store the unit in a dry, well-ventilated area. Do not
store next to corrosive material like fertilizer.
• Store the unit out of the reach of children.
LONG TERM STORAGE
If the unit will be stored for an extended time:
1. Drain all gasoline from the gas tank into a container.
Do not use gas that has been stored for more than
60 days. Dispose of the old gasoline in accordance
with Federal, State and Local regulations.
2. Start the engine and allow it to run until it stalls. This
ensures that all gasoline has been drained from the
carburetor.
3. Allow the engine to cool. Remove the spark plug and
put 1 oz. (30 ml) of high quality motor oil into the
cylinder. Pull the starter rope slowly to distribute the
oil. Reinstall the spark plug.
NOTE: Remove the spark plug and drain all of the oil
from the cylinder before attempting to start the
unit after storage.
4. Change the oil, referring to the Changing the Oil
section. Dispose of the old oil in accordance with
Federal, State and Local regulations.
5. Thoroughly clean the unit and inspect for any loose
or damaged parts. Repair or replace damaged parts
and tighten loose screws, nuts or bolts.
6. To take up less storage area, loosen the handlebar
knobs and fold the handlebar down. The unit is
ready for storage.
TRANSPORTING
• Allow the engine to cool before transporting.
• Secure the unit while transporting.
• Drain the fuel tank before transporting.
• Tighten fuel cap before transporting.
To avoid serious
