OIL AND FUEL MIXING INSTRUCTIONS
Old and/or improperly mixed fuel are the main reasons for the unit
not running properly. Be sure to use fresh, clean unleaded fuel.
Follow the instructions carefully for the proper fuel/oil mixture.
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 and oil
separate. It forms acids when stored. When using alcohol-blended
fuel, use fresh fuel (less than 30 days old).
Using Blended Fuels
If you choose to use a blended fuel, or its use is unavoidable, follow
recommended precautions:
• Always use the fresh fuel mix explained in your operator's manual
• Use the fuel additive STA-BIL® or an equivalent
• Always agitate the fuel mix before fueling the unit
• Drain the tank and run the engine dry before storing the unit
Using Fuel Additives
The bottle of 2-cycle oil that came with your unit contains a fuel
additive which will help inhibit corrosion and minimize the formation
of gum deposits. It is recommended that you use our 2-cycle oil
with this unit.
If unavailable, use a good 2-cycle oil designed for air-cooled
engines along with a fuel additive, such as STA-BIL Gas Stabilizer or
an equivalent. 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 fuel tank.
Mixing the Fuel
Thoroughly mix the proper ratio of 2-cycle engine oil with unleaded
gasoline in a separate fuel can. Use a 40:1 fuel/oil ratio. Do not mix
them directly in the engine fuel tank. See the table below for specific
gas and oil mixing ratios.
NOTE: One gallon (3.8 liters) of unleaded gasoline mixed with one
3.2 oz. (95 ml) bottle of 2-cycle oil makes a 40:1 fuel/oil ratio.
NOTE: Dispose of the old fuel/oil mix according to federal, state and
local regulations.
WARNING: Remove fuel cap slowly to avoid injury from
fuel spray. Never operate the unit without the fuel cap
securely in place.
WARNING: 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.
CAUTION: For proper engine operation and maximum
reliability, pay strict attention to the oil and fuel mixing
instructions on the 2-cycle oil container. Using improperly
mixed fuel can severely damage the engine.
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.

IDLE SPEED ADJUSTMENT
NOTE: Careless adjustments can seriously damage your unit. An
authorized service dealer should make carburetor adjustments.
If after checking the fuel mixture and cleaning the air filter the engine
still will not idle, adjust the idle speed screw as follows:
1. Start the engine and let it run for about 2-3 minutes at a high
speed (full throttle) to warm up. Refer to the Starting and
Stopping Instructions.
NOTE: Ensure the tines are not in contact with the ground when
adjusting the idle.
2. Release the throttle control and let the engine idle. If the engine
stops, use a small Phillips screwdriver to turn the idle speed
screw clockwise, 1/8 of a turn at a time (as needed) until the
engine idles smoothly (Fig. 12).
NOTE: The tines should not rotate during engine idle.
3. If the tines rotate when the engine idles, turn the idle speed
screw counterclockwise 1/8 of a turn at a time (as needed), to
reduce idle speed.
Checking the fuel mixture, cleaning the air filter, and adjusting the
idle speed screw should solve most engine problems. If not and all
the following are true:
• The engine will not idle
• The engine hesitates or stalls on acceleration
• There is a loss of engine power
Have the carburetor adjusted by an authorized service dealer.
WARNING: The tines may turn during idle speed
adjustments. Wear protective clothing and observe all
safety instructions to prevent serious personal injury.
AIR FILTER MAINTENANCE
Cleaning the Air Filter
Failure to maintain your air filter properly can result in poor
performance or can cause permanent damage to your engine.
1. Open the air filter cover by unscrewing the cover screw (Fig. 10).
2. Remove the air filter and the screen that sits behind it (Fig. 10).
3. Wash the filter in detergent and water. Rinse the filter thoroughly
and allow it to dry.
4. Apply enough clean SAE 30 motor oil to lightly coat the filter.
5. Squeeze the filter to spread and remove excess oil.
6. Replace the air filter and the screen that sits behind it (Fig. 10).
NOTE: Operating the unit without the air filter will VOID the warranty.
7. Reinstall the air filter cover. Insert the hooks on the air filter
housing into the slots on the air filter cover (Fig. 11).
8. Swing the air filter cover to the right and align the cover screw
with the cover screw hole (Fig. 11). Tighten the cover screw to
secure the air filter cover.
NOTE: Do not over tighten as this may strip the screw.

REPLACING THE SPARK PLUG
1. Stop the engine and allow it to cool. Grasp the spark plug wire
firmly and pull the cap from the spark plug.
2. Clean dirt from around the spark plug. Remove the spark plug from
the cylinder head by turning a 5/8 in. socket counterclockwise.
3. Inspect the spark plug. If the spark plug is cracked, fouled or
dirty, replace it with a replacement part #753-06193,
Champion® RDJ7J or equivalent spark plug.
4. Use a feeler gauge to set the air gap at 0.025 in. (0.635 mm)
(Fig. 22).
5. Install the spark plug in the cylinder head. Tighten the spark plug
with a 5/8-inch socket, turning it clockwise until snug.
NOTE: If using a torque wrench, torque to:
110-120 in.•lb. (12.3-13.5 N•m). Do not over tighten.
6. Reconnect the spark plug wire.
WARNING: Do not sand blast, scrape or clean
electrodes. Grit in the engine could damage the cylinder.

CLEANING AND STORAGE
CLEANING
• 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, like
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 a fueled unit 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.
• Store the unit out of the reach of children.
Long-term Storage
1. Remove the fuel cap, tip the unit and drain the fuel into an
approved container.
NOTE: Do not use gasoline that has been stored for more than 30
days. Dispose of 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 fuel has been drained from the carburetor.
3. Allow the engine to cool. Remove the spark plug and put 5
drops of any high quality motor oil or 2-cycle 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. Thoroughly clean the unit and inspect for any loose or damaged
parts. Repair or replace damaged parts and tighten loose
screws, nuts or bolts. The unit is ready for storage.
WARNING: To avoid serious personal injury, always turn
your unit off and allow it to cool before you clean or service it.
