How To Prepare The Engine
_lk ARNING: Follow the engine
manufacturer's instructions for the
type of fuel and oil to use. Always
use a safety fuel container. Do not smoke
when adding the fuel mixture to the engine.
When inside an enclosure, do not fill the
fuel tank. Before you add the fuel mixture,
stop the engine. Let the engine cool for
several minutes.
See the engine manufacturer's instructions for
the type of fuel and oil to use. Before you use
the unit, read the information on safety, opera-
tion, maintenance, and storage.
How To Mix The Fuel Mixture
The two cycle engine, used on this snow throw-
er, requires a mixture of gasoline and oil for lu-
brication 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
dean gasoline container. Always use fresh,
dean, unleaded gasoline.
Mix gasoline and oil as follows:
1. Pour one (1) U.S. quart of fresh, clean, un-
leaded automotive gasoline into a one gallon
size gasoline container.
2. Add 2.6 ounces of clean, high quality, two-
cycle oil to the gasoline container.
IMPORTANT: Do net use outboard motor
oil or multi-viscosity oils,such as 10W-30
or 10W-40.
3, install the fuel cap onto the gasoline contain-
er. Vigorously shake the gasoline container
to mix the oil with the gasoline.
4. Add an additional three (3) U.S. quarts of
gasoline to the gallon container. Again shake
the gasoline container.
Before You Operate
Before you operate your new snow thrower,
please review the following checklist:
• Make sure all assembly instructions have
been completed.
• Make sure the discharge chute rotates freely.
• Make sure that no loose parts remain in the
carton.
As you learn how to propedy use the snow
thrower, pay extra attention to the following im-
portant items.
• Make sure the fuel tank is filled with the
correct mixture of gasoline and oil.
• Become familiar with the location of all
controls and understand their function.
• Before starting the engine, make sure all
controls operate correctly.
Do not fill the fuel tank with gasoline that does not have oil mixed in it. Shake the
gasoline container before each filling of the fuel tank.
