Operating Your Cultivator - Yard Machines 21A-120R000 Operator's Manual

SECTION 4: OPERATING YOUR CULTIVATOR
Oil and Gas 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 sepa-
rate. It forms acids when stored. When using alcohol-
blended fuel, use fresh fuel (less than 60 days old).
Using Blended Fuels
If you choose to use a blended fuel, or its use is
unavoidable, follow recommended precautions.
• Always use fresh fuel mix per 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 use of fuel additive, 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 fuel tank.
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.
Thoroughly mix the proper ratio of 2-cycle engine oil
with unleaded gasoline in a separate fuel can. Use a
32:1 fuel/oil ratio. Do not mix them directly in the
engine fuel tank. See Figure 15 for specific gas and
oil mixing ratios.
NOTE: Two gallons (7.6 liters) of unleaded gasoline
mixed with one 8 oz. (236 ml.) bottle of Arnold 2 Cycle
Oil makes a 32:1 fuel/oil ratio OR one gallon (3.8 liters)
of unleaded gasoline mixed with one 4 oz. (120 ml.)
bottle of Arnold 2 Cycle Oil makes a 32:1 fuel/oil ratio.

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: Add fuel in a clean, well
ventilated area outdoors. Wipe up any
spilled fuel immediately. Avoid creating
a source of ignition for spilt fuel. Do
not start the engine until fuel vapors
dissipate.
NOTE: Dispose of the old fuel/oil mix in accordance
to Federal, State, and Local regulations.
Filling The Fuel Tank
Fill or add fuel to the tank only when the cultivator is
in a horizontal position. See figure 16.
