OPERATION
BEFORE STARTING THE ENGINE
Mix gasoline and oil as follows:
WARNING: Experiences indicates that alcohol
blended fuels (called gasohol or those using
ethanol or methanol) can attract moisture
which leads to separation and formation of acids dur-
ing storage. Acidic gas can damage the fuel system
of an engine while in storage.
1.
Pour one (1) U.S. quart of fresh, clean, unleaded auto-
motive gasoline into a one gallon size gasoline contain-
er.
2.
Add 2.6 ounces of clean, high quality, Husqvarna two−
cycle oil to the gasoline container.
IMPORTANT: Do not use outboard motor oil or mul-
ti−viscosity oils,such as 10W−30 or 10W−40.
NOTE: To avoid engine problems, the fuel system must
be emptied before storage for 30 days or longer. Start
the engine and let it run until the fuel lines and carbure-
tor are empty. Use the carburetor bowl drain to empty
residual gasoline from the float chamber. Use fresh fuel
next season. See the Storage section in this manual for
additional information.

4.
Install the fuel cap onto the gasoline container. Vigor-
ously shake the gasoline container to mix the oil with
the gasoline.
Add an additional three (3) U.S. quarts of gasoline to
the gallon container. Again shake the gasoline contain-
er.
Never use engine or carburetor cleaner products in the
fuel tank or permanent damage can occur.
WARNING: Gasoline is flammable. Always use
caution when handling or storing gasoline.
Do not fill fuel tank while snow thrower is run-
ning, when it is hot, or when snow thrower is in an
enclosed area.
Keep away from open flame or an electrical spark and
do not smoke while filling the fuel tank.
Never fill the tank completely. Fill the tank to within
HOW TO MIX THE FUEL MIXTURE
The two cycle engine, used on this snow thrower, requires a
mixture of gasoline and oil for lubrication of the bearings and
other moving parts. The correct fuel mixture ratio is 50:1
(2.6
oz. oil per one gallon of gas − see the Fuel Mixture
Chart). Gasoline and oil must be pre−mixed in a clean gaso-
line container. Always use fresh, clean, unleaded gasoline.
1/4”
−1/2” from the top to provide space for expansion
of fuel.
Always fill fuel tank outdoors and use a funnel or
spout to prevent spilling.
Make sure to wipe up any spilled fuel before stating
the engine.
