FUELING ENGINE
_WARNING: Remove fuel cap slowly
when refueling.
This engine is certified to operate on um
leaded gasoline. Befc_e operation, gasoline
must be mixed with a good quality synthetic
2*cycle air-cooled engine oil designed to be
mixed at a ratio of 40:1. PoulanANeedEater
brand synthetic oil is recommended. Mix gasc_
line and oil at a ratio of 40:1. A 40:1 ratio is ob_
tained by mixing 3.2 ounces (95 ml) of oil with
1 gallon (4 liters) of unleaded gasoline.
DO NOT USE automotive oil or boat oil.
These oils will cause engine damage. When
mixing fuel, follow instructions printedon con_
tainer. Once oil is added to gasoline, shake
container momentarily to assure that the fuel
is thoroughly mixed. Always read and follow
the safety rules relating to fuel before fueting
your unit.
IMPORTANT
Experience indicates that alcohol blended
fuels (called gasohol or using ethanol or
methanol) can attract moisture which leads to
separation and formation of acids during stor-
age. Acidic gas can damage the fuel system
of an engine while in storage.
Toavoid engine problems, empty the fuel sys*
tern before storage for 30 days or longer.
Drain the gas tank, start the engine and let it
run until the fuel lines and carburetor are
empty. Use fresh fuel next season.
Never use engine or carburetor cleaner prod-
ucts in the fuel tank or permanent damage
may occur.
See the STORAGE section for additional im
formation.
