Operation - McCulloch TrimMac ST+ Instruction Manual

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 unleaded
gasoline. Before operation, gasoline must be
mixed with a good quality 2-cycle air-cooled en-
gine oil designed to be 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 mo-
mentarily 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.
