FUELING ENGINE
WARNING:
Remove fuel cap slowly
when refueling.
This engine is certified to operate on unleaded
gasoline. Before operation, gasoline must be
mixed with a good quality 2-cycle air-cooled en-
gine oil. We recommend McCulloch® brand 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 dam-
age. When mixing fuel, follow instructions
printed on oil container. Once oil is added to
gasoline, shake container momentarily to as-
sure that the fuel is thoroughly mixed. Always
read and follow the safety rules relating to fuel
before fueling your unit.
IMPORTANT

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
