OPERATION
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
authorized 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. We recommend Partner
®
brand oil mixed at a ratio of 40:1 (2.5%). A
40:1 ratio is obtained by mixing 5 liters of un-
leaded 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 contain-
er. Once oil is added to gasoline, shake con-
tainer 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 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 or permanent
damage may occur.
