FUELING ENGINE
WARNING:
Remove fuel cap slowly
when refueling.
This engine is certified to operate on un-
leaded gasoline. Before operation, gasoline
must be mixed with a good quality 2-cycle air-
cooled engine oil mixed at a ratio of 40:1
(2.5%). A 40:1 ratio is obtained by mixing 5
liters of unleaded gasoline with 0,125 liter of
oil. DO NOT USE automotive oil or boat oil.
These oils will cause engine damage. When
mixing fuel, follow instructions printed on oil
container. Once oil is added to gasoline,
shake container momentarily to assure that
the f uel is thoroughly mixed. Always read and
follow t he safety rules relating to fuel before
fueling 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. To avoid engine
problems, empty the fuel system before stor-
age 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 products in the fuel tank orpermanent
damage may occur.
