FUELING ENGINE
WARNING:

This engine is certified to operate on unleaded
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. Mix gasoline and oil at a r atio of 40:1. A
40:1 r atio is obtained by m ixing 3. 2 ounces (95
ml)of oil with 1gallon (4 liters)of unleaded gaso-
line. DO NOT U SE automotive oil or boat oil.
These oils will cause engine dam age. When
mixing fuel, follow instructions printed o n con-
tainer. Once oil is added to gasoline, shake con-
tainer momentarily to assurethat the fuel is thor-
oughly m ixed. Always read and follow the safety
rules relating to fuel before fueling your unit.

(called gasohol or using ethanol or methanol)
can attract moisture w hich leads to separ ation
and formation of acids during storage. Acidic
gas can damage the fuel system of an engine
while in storage. To avoid engine problems,
empty the fuel system before storage for 30
days or longer. D r ain t he gas tank, start the en-
gine and let it run until the fuel lines and carbure-
tor are empty. Use fr esh fuel next season. Nev-
