OraLAND FUEL MmXH_G H_STRUCTmONS

Old and/or improperly raked fuel are the main reasons
for the unit not running properly. Be sure to use fresh
(less than 60 days old), 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 gaso%e 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 and
leads to formation of adds during storage. When using

alcohol-blended fuel, use fresh fuel.
Using Blended Fuels

if you choose to use a blended fuel or its use is
unavoidable, follow recommended precautions:

• AHways use the fresh rue[ mix explained in your
operator's manual

• Always shake 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 always use Craftsman 2-cycle oil

with this unit.
if Craftsman 2-cycle oil is unavailable, use a good 2-

cycle oil designed for air-cooled engines along with a
fuel additive, such as STA-B[L" 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 tanL

To Obtain Correct Fuel Mix:
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 Fuel Mixture Table 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.
