HELPFUL TIP
To obtain the correct oil mix
ratio, pour 3.2 ounces of
2-- cycle synthetic oil into
one gallon of fresh gas.
This engine is certified to operate on un-
leaded gasoline. Before 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. A 40:1 ratio is ob-
tained by mixing 3.2 fluid ounces (95ml) of oil
with 1 gallon (4 liters) of unleaded gasoline.
Pour the entire contents of the 3.2 ounce (95
ml) container of oil into 1 gallon (4 liters) of
gasoline to achieve the proper fuel mixture.
DO NOT USE automotive or marine oil.
These oils will cause engine damage. When
mixing fuel follow the instructions printed on
the container . Once oil is added to gasoline,
shake container momentarily to assure that
the fuel is thoroughly mixed. Always readand
follow the safety rules relating to fuel before
fueling your unit.
CAUTION: Never use straight gasoline in
your unit. This will cause p ermanent engine
damage and void the limited warranty .
