OPERATION
BEFORE STARTING ENGINE
WARNING:
Be sure to read the fuel
information in the safety rules before you be-
gin. If you do not understand the safety rules,
do not attempt to fuel your unit. Contact an au-
thorized service dealer.
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. Mix gasoline and oil at a ra-
tio of 40:1 (2.5%). A 40:1 ratio is obtained by
mixing 5 liters of unleaded petrol with 0,125 li-
ter of oil. DO NOT USE automotive oil or boat
oil. These oils will cause engine damage.
When mixing fuel, follow instructions printed
on container. 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
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 sys-
tem 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.
