GENERAL INFORMATION
Figure 6
1. Mix the gasoline and oil in the correct ratio for your
unit. Refer to “MIXING INSTRUCTIONS FOR
GASOLINE AND OIL” on page 2 - 3.
2. Clean the area around snowthrower fuel tank cap
so foreign matter does not get into the fuel tank.
Remove the cap from the fuel tank.
3. Fill snowthrower fuel tank to within 1/4 - 1/2 inch
from the top of the tank, not the filler neck.
4. Install the cap securely on snowthrower fuel tank.
Draining The Fuel Tank
To assure safe servicing of your snowthrower, it is
critical that the fuel tank be drained. To drain the fuel
tank on your snowthrower, use the following procedure:
1. Use a pump type siphon to remove as much fuel
from the tank as possible. Dispose of fuel
properly. One method of disposing of left over fuel
is to put it in the car. If you have a half tank of fuel
in the car, a gallon or two of fuel mix will blend with
the gas and have no effect. If the fuel is extremely
old and does not smell like gasoline, we would not
recommend its use in any engine. Contact your
local authorities for disposal instructions.
2. Use the primer and choke and start the engine. It
should run several minutes to consume the fuel in
the carburetor and fuel line. When the engine
stops, attempt to start it again. Use the primer
and choke. The engine may start and stop 2 or 3
times. Repeat until you cannot start the engine.
Note: Draining the fuel tank and letting the
unit run out of fuel is a critical servicing
procedure when preparing your snowthrower
for storage. Expending fuel from the engine
will prevent gum-like varnish deposits from
forming in the carburetor, fuel line, and fuel
tank. Such deposits, if allowed to form, will
cause starting problems the following season.
OFF SEASON STORAGE
Properly preparing the machine for off season storage
is the single most important thing that can be done to
prevent problems. The summer heat will rapidly
evaporate fuel in the tank and carburetor. Dried fuel in
the carburetor can and often does plug the fuel
passages and prevent starting the following snow
season. We recommend the use of a petroleum based
fuel stabilizer during the snow season. The stabilizer
will help keep fuel fresh and assist with starting.

GASOLINE CONTAINER
Because the gasoline/oil mixture in the
snowthrower fuel tank is explosive, the fuel
mixture must be drained outdoors, away from fire
and flame. Do not smoke while draining gasoline.

Because gasoline/oil mixture in the snowthrower
fuel tank is explosive, the fuel mixture must be
drained outdoors, away from fire and flame. Do
not smoke while draining gasoline. If fuel mixture
